241941003 Frigidaire Refrigerator Relay Starter is a compressor start relay used on many Frigidaire household refrigeration units; it is a small electromechanical or solid-state device that momentarily connects the compressor’s start winding (or alters start-circuit characteristics) to provide the torque required for initial motor acceleration. The part is typically mounted at or near the compressor and is identified by its part number to ensure electrical and mechanical compatibility with the specific compressor model and control scheme.
Within the appliance, the relay starter is part of the compressor start circuit and interfaces directly with the compressor motor, any external start capacitor or PTC element, the motor overload protectorand the thermostat or control board that supplies line voltage. During a start event the relay provides the necessary phase shift or connection to engage the start winding, then opens or changes characteristics once the motor reaches operating speed; correct operation is essential for reliable compressor starts, acceptable inrush currentsand coordinated interaction with overload protection and control electronics.
In this article you will find a technical overview of the relay starter’s function and typical designs, guidance on confirming compatibility with a specific compressor or refrigeration model, a list of common failure symptoms (no-start, humming, frequent or failed restarts, elevated starting current, visible damage), practical troubleshooting methods (visual inspection, terminal/continuity checks, current and voltage measurements, swap or bench tests) and considerations for safe and correct replacement (matching electrical ratings and terminal configuration, correct mounting and environmental protectionand verification steps after installation). The focus is on actionable diagnostic and replacement guidance appropriate for technicians, engineersand informed appliance owners.

Function and Role of the Compressor Start Relay in Frigidaire Refrigerators
The 241941003 Frigidaire Refrigerator Relay Starter is the transient switching device that delivers current to the compressor start winding only during startup, allowing a single‑phase hermetic compressor to develop the initial torque required to begin rotation.Common implementations are PTC (positive temperature coefficient) thermistor starters or electromechanical relay/overload assemblies; both types remove the start circuit once the motor reaches run speed to avoid prolonged current through the start winding. Proper function of this starter directly affects compressor starting behavior, inrush current profileand the thermal loading seen by the motor and overload protector.
In practical service, the relay starter must match the compressor’s electrical characteristics and the refrigerator model’s terminal/configuration layout; substituting the wrong type or rating can lead to repeated start failures or nuisance overload trips without addressing root causes such as mechanical seizure or low refrigerant. technicians typically verify starter behavior by checking for correct continuity/resistance on the start/run terminals, observing the relay action (or PTC resistance change) during startupand comparing symptoms against the compressor’s expected start profile. The relay starter does not correct refrigerant charge issues or internal motor damage, so replacement should be combined with diagnostic checks of the compressor and control circuitry.
- Typical symptoms of a failed starter: repeated clicking, compressor humming without spinningor immediate overload trips on start.
- key compatibility factors: rated supply voltage, terminal arrangement, built‑in overload vs separate overloadand physical mounting for specific Frigidaire models.
- Common shop checks: resistance/continuity across terminals, visual inspection for burned contactsand controlled substitution with a known‑good starter.

How the 241941003 Frigidaire Refrigerator Relay Starter Operates Within the compressor Start Circuit
The 241941003 Frigidaire Refrigerator Relay Starter functions as the momentary feed in the compressor start circuit, delivering the inrush current needed to energize the compressor’s start winding until the motor reaches synchronous speed. In single‑phase hermetic compressors the start relay either momentarily connects the start winding (mechanical/relay type) or changes its resistance profile (PTC type) so that the start winding is effectively removed from the circuit once the rotor attains sufficient RPM. Proper operation depends on matching the relay’s electrical and thermal characteristics to the compressor: the relay must tolerate the compressor’s locked‑rotor current and operate reliably across the refrigerator’s expected supply voltages and ambient temperatures. A failed or mismatched relay will commonly cause the compressor to hum, click repeatedly, or fail to start while drawing high current, because the start winding remains improperly engaged or disconnected at the wrong time.
The relay interacts with the overload protector and the compressor’s internal windings; when diagnosing or replacing it, verify terminal layout and ratings rather than relying solely on physical fit. Practical checks include visual inspection for overheating or melted plastics, continuity checks of the relay terminalsand observing compressor behavior when a known-good relay is installed. Typical diagnostic cues and installation considerations include:
- Humming/no‑start condition while the compressor draws elevated current.
- Repeated clicking at startup indicating a relay that cycles under thermal or current stress.
- Visible heat damage, corrosion on terminalsor burned smells at the relay or harness.
- Confirming terminal markings and electrical specs to ensure compatibility before replacement.

|---|---|
| Function | Provides a timed inrush to the start winding and removes it once the compressor achieves running speed. |
| Common failure symptom | Compressor hums without starting, frequent trips of overloador repeated relay clicking. |
| Service check | Visual inspection, continuity/resistance checksand substitution with a known-compatible relay. |
Common Failure Symptoms and Diagnostic Indicators of a Faulty Relay Starter
The 241941003 Frigidaire Refrigerator Relay Starter is the electromechanical device that supplies the compressor’s start winding with a high inrush of current or momentary connection (depending on whether it is a PTC or current-sensing relay) to get the compressor up to running speed. When the relay fails, the compressor will either not start at all, will produce a continuous humming noise while attempting to startor will start intermittently and then overheat. In practice, confirm the relay’s part number and physical mating to the compressor terminals before replacement; mismatched relay types (PTC vs. current-sensing) or incorrect pin layouts can allow temporary operation but cause repeated starter failures and accelerated compressor wear.
- No crank / continuous humming with no run - the relay isn’t supplying the start winding.
- Intermittent starts or delayed starts – internal contacts or PTC element degrading.
- Frequent tripping of the circuit breaker or blown fuses at start – excessive inrush current from a failing relay or stuck start winding.
- Visible overheating, meltingor a burnt odor at the relay – internal failure or shorting.
Diagnosing a suspect starter relay combines auditory/visual observations with basic electrical checks: with power removed, inspect for melted plastic or corrosion; use an ohmmeter to check for open circuits between start, run and common terminals (an open start path typically indicates failure).Under powered conditions (and observing safety precautions), measure line voltage at the relay during a start attempt and use a clamp meter to capture peak starting current – a healthy relay will allow a brief high current surge followed by normal running current, whereas a failed relay shows either no surge or a prolonged, excessive surge. If the relay is removable, bench-testing by substituting a known-good relay of the same specification or using a controlled momentary connection to the start winding can confirm whether the issue is the relay or the compressor; if electrical tests repeatedly show open or erratic continuity on the start connection, replacement of the relay is the standard repair.

| Electrical indicator | Open circuit on start terminal or abnormal starting current on clamp meter. |
Compatibility and Supported Frigidaire Models for the 241941003 Relay Starter
The 241941003 Frigidaire Refrigerator Relay Starter is a start device that provides a timed or current-sensing connection to the compressor’s start winding so the hermetic single‑phase compressor can accelerate to running speed. Technically, the relay starter must match the compressor’s electrical characteristics – nominal line voltage, locked‑rotor current (LRA)and terminal arrangement – and might potentially be implemented as a PTC-style solid state device or a mechanical/current relay. Compatibility with a Frigidaire model therefore depends less on the cabinet model number and more on the compressor nameplate data and the relay’s terminal/mounting configuration; installers should verify the compressor’s label (voltage, Hz, and terminal designations such as S/R/C) before substituting this part.
For practical field assessment, confirm whether the relay includes an integral overload or if a separate overload device is requiredand inspect the physical mounting clip or bracket to ensure secure attachment to the compressor housing.Mismatched starters can cause repeated hard starts, excessive current draw, overheatingor failure to start; typical compatibility checks include comparing the 241941003 relay’s voltage rating and terminal layout to the compressor, verifying the presence of the necessary start capacitor or overload in the circuitand confirming that the relay’s dimensions and connector type fit the compressor.technicians frequently enough replace the relay and overload together or consult compressor part numbers for direct cross‑references when exact model matches are needed.
- Verify compressor nameplate: voltage/Hz, LRA, and terminal letters (S, R, C)
- Match terminal configuration (two‑terminal vs three‑terminal) and connector type
- Confirm whether the relay contains an overload or a separate overload is present
- Check physical mounting method (clip, bracket) and clearance for installation
| Item | Description |
|---|---|
| Voltage rating | Typically 115-120 V AC for common Frigidaire compressors |
| Terminal configuration | Two‑terminal (inrush/PTO) or three‑terminal (S, R, C) compressors |
| Function | Engages start winding until motor reaches run speed; might potentially be PTC or current relay |
| Mounting | Compressor clip or bracket; physical fit must match compressor housing |
Replacement Considerations and Step-by-Step Installation Guidelines for the Relay Starter
The 241941003 Frigidaire Refrigerator Relay Starter provides the brief high-torque boost required to engage the compressor’s start winding and then releases once the motor reaches operating speed. in practice this part can be a PTC or electronic starter and must match the compressor’s electrical characteristics, terminal layoutand mounting method. Failed relays often present as a humming compressor that repeatedly attempts to start, long crank timesor thermal cut-out trips; these symptoms help differentiate a starter failure from a seized compressor or a defective overload protector. Verify compatibility by matching the relay’s voltage rating, terminal labels (S, R, C)and harness connector to the appliance service manual or the original part before replacement to avoid mismatched starting behavior or premature failure.
- Safety: Disconnect power at the breaker before any access panel removal or wiring work.
- Access: remove the compressor access panel and locate the relay/overload assembly mounted on the compressor can or within the wiring harness.
- Identification: compare the new unit to the old for terminal arrangement and mounting tabs; mark wire positions or photograph before disconnecting.
- Replacement: remove retaining clip or screws, transfer or replace both relay and overload if applicable, ensure a flat, secure fit against the compressor for heat dissipation.
- Verification: after reassembly and power restoration, listen for a prompt start (typically within a few seconds); repeated click-start cycles indicate further diagnostics (check start/run capacitors, motor windingsor locked rotor conditions).
- Measurement: use a clamp ammeter to check start and run currents against the service specification; abnormal start current magnitudes or extended cranking point to compressor or circuit problems rather than the relay alone.
| Item | Description |
|---|---|
| Function | Provides momentary energization of the compressor start winding and disengages at run speed |
| terminals | Match S, R, C markings to compressor and harness; incorrect wiring can prevent start or damage windings |
| Compatibility | Confirm voltage, mounting typeand connector fit for the Frigidaire model before installation |
Troubleshooting and Diagnostic Procedures: multimeter Tests, Wiring Checksand Load Verification
The 241941003 Frigidaire Refrigerator Relay Starter serves as the start-device that momentarily applies additional current to the compressor’s start winding so the motor can overcome initial inertia and reach running speed.In practice this start device will either briefly connect the start winding (electromechanical relay) or change resistance/path (solid-state/PTS-type) so that the compressor gets an elevated starting torque and then the circuit transitions to the run winding only. When checking compatibility, note that the starter must match the compressor’s expected start/load characteristics and terminal configuration; a mismatched starter can allow normal supply voltage but fail to deliver the required start current or timing, causing long cranks or a locked/compressor trip condition.
Diagnostics combine simple multimeter checks with live wiring and load verification to isolate the fault to the starter, compressor, or wiring. Begin with power removed: visually inspect for burns or loose spade terminals, then use an ohmmeter/continuity check on the starter device and the start/run windings to detect opens or shorts.With power restored and proper safety precautions, measure AC voltage at the compressor terminals and use a clamp meter to compare starting current against expected behavior-high inrush followed by a drop to running current indicates a functioning starter and motor. Typical actionable checks include confirming continuity of the starter coil or PTC element, verifying that wiring harnesses and connectors maintain low-resistance connections under load, and observing whether the starter actually switches or changes resistance during a crank; if the starter passes static tests but the compressor fails to draw start current, suspect a mechanical compressor fault or incorrect starter model.
- Visual/wiring: inspect connectors, insulationand spade terminals for corrosion or looseness.
- Static multimeter: continuity/ohms on starter and start/run windings (open = replace).
- Live checks: AC voltage at supply and compressor; clamp meter for start inrush vs running current.
- Functional swap: replace with known-good starter of the same specification to confirm behavior.
| item | Description |
|---|---|
| Multimeter resistance | Starter/PTC: low-to-moderate ohms or continuity expected; open circuit indicates failure. |
| Supply voltage | Nominal ~120 VAC at the fridge supply; absence or large drop under load indicates wiring or control issue. |
| Load verification | High initial inrush on clamp meter that falls to steady run current indicates proper starting action; sustained high draw suggests starter or motor problem. |
Q&A
What is the 241941003 Frigidaire refrigerator relay starter and what does it do?
The 241941003 is a compressor start relay/overload assembly used on many Frigidaire (and some kenmore) refrigerators.Its job is to give the compressor an extra electrical push to start (start circuit) and to protect the compressor from overheating or drawing too much current (overload). Without a working start relay/overload the compressor may hum, fail to startor not run at all, causing loss of cooling.
What are the common symptoms of a failing 241941003 relay starter?
Typical symptoms include: refrigerator not cooling, compressor humming but not starting, intermittent running, clicking noises at the rear of the fridgeor the compressor starting only after several attempts. Visual signs include burn marks, melted plasticor a broken housing on the relay assembly.
How can I test the 241941003 relay to confirm it is bad?
Safe, common checks: first disconnect power. remove the relay assembly from the compressor and inspect visually for damage. With a multimeter check for continuity between appropriate relay terminals (note: PTC solid-state relays may not show obvious resistance values).If you have access to a known-good relay you can swap to see if the compressor starts. For technicians, measuring inrush current with a clamp meter during start can confirm a start-device failure. Avoid applying mains voltage directly to the relay unless you are trained and taking safety precautions.
How do I replace the 241941003 relay starter and what safety steps should I follow?
Disconnect power to the refrigerator. Pull the fridge out and remove the access panel to the compressor. Unplug the relay/overload from the compressor terminals (note or photo the wire positions first). Remove the old relay and install the new one in the same orientation, reconnect wires, replace the coverand power up. Always ensure power is OFF before working and avoid touching refrigerant lines or compressor internals.If you are not comfortable, have a qualified appliance technician do the replacement.
Is the 241941003 relay starter compatible with my Frigidaire model?
Compatibility depends on the refrigerator model and compressor type. 241941003 is a common OEM relay for many Frigidaire models, but you should verify compatibility by checking your refrigerator model number and using the manufacturer parts lookup or a trusted parts supplier. Do not rely only on visual similarity-confirm part numbers or OEM cross-references.
Will replacing the relay starter fix the compressor if the fridge still won’t cool?
Replacing a faulty relay/overload will fix starting problems caused by the relay itself. However, if the compressor is mechanically seized, has internal electrical shortor the sealed refrigerant system has a leak, replacing the relay will not restore cooling. If the compressor still does not start after a known-good relay is installed, further diagnosis by a technician is required (e.g., compressor electrical tests, refrigerant pressure checks).
How long does the 241941003 relay starter typically last and is it worth replacing on an older fridge?
Start relays can last many years but are subject to wear and heat stress and may fail after a variable lifetime (often 5-15+ years depending on usage and environment). If the rest of the refrigerator is in good condition and the repair cost is modest, replacing the relay is usually economical. For very old units with other major issues, compare repair cost to replacement cost of a new appliance.
Where can I buy a genuine 241941003 relay starter and should I buy aftermarket options?
You can buy the part from Frigidaire authorized parts dealers, appliance parts storesor reputable online sellers. OEM (genuine Frigidaire) parts are recommended to ensure fit and function. Aftermarket options may be cheaper and sometimes acceptable, but verify they match the OEM specifications and terminal configuration. Always confirm seller return policy and warranty in case the part is defective.
