241941005 Frigidaire Refrigerator Start Device is a compressor start device supplied for certain Frigidaire household refrigeration units; it functions as the electrical component that assists a single‑phase hermetic compressor through its initial startup phase. In practice this part is a start relay/thermistor style starter (often packaged with or located adjacent to an overload protector) that momentarily modifies the compressor motor circuit to provide the higher starting torque required to bring the compressor up to operating speed.
Inside the appliance the start device interfaces directly with the compressor terminals and the refrigerator’s supply circuit, and it interacts with the compressor’s start and run windings, the thermal overload protector, and the incoming line voltage or control board outputs. By providing a timed or current‑sensing change in the motor circuit,the device reduces stall current and prevents prolonged starting attempts; when it fails or stays engaged the compressor will either not start,hum continuously,or draw excessive current,which can lead to nuisance tripping or motor damage. The component is typically mounted at the compressor terminal block or on the compressor body and is used across domestic refrigerators and freezers that employ single‑phase hermetic compressors without permanent start capacitors.
In the remainder of this article readers will find a technical explanation of the start device’s operating principle and expected electrical behavior, guidance on model and compatibility checks, a list of common failure symptoms to distinguish start‑device problems from other faults, practical troubleshooting steps (multimeter checks, continuity/resistance expectations, safe jumper tests, and how to isolate the overload and compressor), and considerations for safe replacement such as matching electrical ratings, mounting orientation, and basic safety precautions to follow before replacing the unit. The details is intended to help technicians, engineers, and informed appliance owners diagnose start‑related faults and make informed decisions about repair or replacement while observing safe work practices.

Function and Role of the Compressor Start Device in Frigidaire Refrigeration Systems
The 241941005 Frigidaire Refrigerator Start Device functions as the initial torque provider for the compressor motor by energizing the compressor’s start winding during the few hundred milliseconds required to overcome locked-rotor torque. In practical terms, this part acts as a temporal or sensing intermediary (often a PTC element or an electronic relay) that supplies the start winding with the correct phase-shifted current and then removes it once the motor reaches operating speed. Compatibility is persistent by the compressor’s electrical characteristics and terminal configuration, so the 241941005 Frigidaire Refrigerator Start Device must match the OEM terminal layout and expected voltage/current ratings to function correctly as a replacement component.
During normal operation the device permits a brief, controlled inrush to the start circuit and then disengages, limiting heat build-up and reducing continuous current through the start winding. Common failure modes include inability to open the start path (resulting in a continuously energized start winding and overheating), failure to provide sufficient starting torque (compressor hums but does not start), and intermittent operation that yields repeated starts or cycling. Technicians typically verify device behavior by checking start-winding continuity, comparing locked-rotor current to specification with a clamp ammeter, and confirming the replacement matches the original part’s terminal assignments and mounting; replacing the start device without confirming these parameters can mask underlying compressor or capacitor faults.
- Symptoms of a failing start device: persistent humming, repeated clicking, high inrush current, or compressor that only starts intermittently.
- Installation check: verify terminal mapping, voltage rating, and physical mounting before replacing the unit.
- Diagnostic tip: compare measured locked-rotor current and start-winding resistance against service data to isolate start device vs. compressor motor faults.

how the 241941005 Frigidaire Refrigerator Start Device Interfaces with the Compressor and Control Circuitry
The 241941005 Frigidaire Refrigerator Start Device serves as the interface between the refrigerator’s control circuitry and the compressor’s start winding, providing the brief, elevated excitation needed to bring the hermetic compressor up to operating speed. In practice this component either switches the start winding in and out of the circuit (mechanical relay style) or changes its series resistance dynamically (PTC/solid-state style) so the compressor receives a higher starting torque and then transitions to the run winding only. The control board or thermostat supplies the start signal and the start device responds by briefly routing current to the start winding; once the compressor reaches near-run speed the device opens or increases resistance so the start winding is removed from the circuit. Fault modes commonly seen in the field include a device that fails to open (causing overheating) or fails to close (resulting in a humming compressor and no start).
- Primary behavior: engage start winding briefly, then disengage to allow continuous run on the run winding.
- compatibility: intended for single-phase hermetic compressors used in many Frigidaire household refrigerators; must match terminal layout and electrical ratings of the original part.
- Field symptoms: long-starting, repeated attempts to start, or a compressor that hums but doesn’t run indicate possible start device or overload issues.
| Item | Description |
|---|---|
| Function | Provide/switch the initial current to the compressor start winding, then remove it when motor attains speed. |
| Typical connection | Inline between start winding and supply or connected to a control relay; works with the compressor overload protector and control board. |
| Service check | Verify correct terminal continuity, observe starting current with an ammeter, and confirm the start winding is removed after a brief interval. |
When replacing or troubleshooting the start device, match electrical ratings, physical mounting, and terminal configuration to ensure reliable operation with the refrigerator’s control circuitry and the compressor’s overload protector.Technicians should verify sequence: control board applies start signal → start device engages start winding → compressor accelerates → start device disengages; deviations from that sequence point to either the start device, wiring, or the control module. In practice, a speedy bench check using a multimeter for continuity and an ammeter during a start cycle combined with visual inspection for heat damage will distinguish a bad start device from a weak compressor or a failed control board; if the control board never issues a start command, replacing the start device alone will not restore compressor starting.
Common Failure Symptoms and Diagnostic Indicators of a Faulty Start Device
The 241941005 Frigidaire Refrigerator Start Device provides the temporary electrical path and/or surge necesary to energize the compressor’s start winding until the motor reaches running speed. In practice this part may be a relay, PTC element, or solid‑state starter depending on the model; its expected behavior is to present a low impedance to the start circuit only during the initial milliseconds to seconds of startup and then switch out of the circuit. Technicians should understand that compatibility is determined by the compressor type, terminal configuration, and supply voltage-installing a physically similar unit with different switching characteristics can result in slow starts, excessive starting current, or repeated overload trips. For example, a correctly matched start device will allow a cold compressor to begin turning under normal load, whereas a unit with burnt contacts or altered timing characteristics may repeatedly allow only a brief, insufficient current pulse.
- Compressor hums but never starts; motor feels warm and cycling often follows.
- Intermittent starts where the appliance runs sometimes and stalls on other attempts.
- Frequent tripping of the refrigerator’s overload protector or household circuit breaker at startup.
- Visible burning, scorch marks, or melted terminals at the start device or relay socket.
| Item | Description |
|---|---|
| Coil/element resistance | Measure with a multimeter; an open or extremely high reading indicates failure. |
| starting current behavior | Use a clamp meter on the compressor supply: unusually low or excessively high locked‑rotor current suggests a faulty starter. |
| Physical/thermal signs | Discoloration, deformation, or tripped thermal cutouts point to overstress or internal failure. |
Diagnostic workflow typically begins by isolating power and inspecting the start device and connector for damage,then performing electrical checks: continuity/resistance across the device,verifying that the start circuit is engaged only during startup,and comparing measured values against service specifications for the specific compressor. Use a clamp meter to observe the in‑rush (locked‑rotor) current and verify that the starter reduces or times out as expected; if the device never provides the initial current pulse or allows excessive sustained current, replacement is warranted. For replacements, match the OEM part number, terminal layout, and voltage ratings-or consult compressor data-to avoid mismatched timing or protection characteristics; always disconnect mains power before swapping components and follow safe handling practices when bench‑testing.
Replacement considerations and Step-by-Step Installation Procedures for the Start Device
The 241941005 Frigidaire refrigerator Start Device is a motor-start component designed to assist the compressor in overcoming locked-rotor torque during initial energization. It typically functions as a PTC or relay-type start assist that temporarily increases starting torque and then drops out to allow the compressor to run on its run winding. technicians should evaluate compatibility with the compressor type and supply voltage before replacement: confirm that terminal layout, mounting clip, and thermal protection characteristics match the OEM part and that the device is rated for the refrigerator’s nominal line voltage and compressor nameplate specifications. Common failure indicators include repeated clicking at startup, a humming compressor that does not start, or a start device that runs abnormally hot; these symptoms should be corroborated by measuring line voltage at the compressor and comparing the motor current against the compressor’s RLA on the nameplate.
Replacement requires safe isolation of the appliance,correct identification of the start device and its associated thermal protector,and verification of mechanical and electrical connections after installation. Disconnect power and label wiring before removal to preserve terminal orientation; inspect the compressor terminals for corrosion or damage and replace any degraded connectors. After installing the new unit, restore power and observe the compressor for a normal start cycle while measuring current with a clamp meter to ensure inrush and running currents are within expected ranges listed on the compressor nameplate; if the compressor still fails to start or draws excessive current, further compressor or refrigeration circuit diagnostics are required rather than repeated start device replacements.
- Disconnect mains power and remove the access panel to expose the compressor and start device.
- Identify and document terminal positions and any thermal protector wiring; detach connectors using the correct-size crimp or push tools.
- Remove the old start device, inspect mounting clip and terminals, and install the replacement ensuring firm contact and proper orientation of the thermal protector.
- Secure wiring with correct connectors, avoid sharp bends or pinched wires, and reattach the access panel.
- Restore power, observe the first start cycle, and measure running and inrush current to confirm normal operation per compressor nameplate values.

Q&A
What is the 241941005 Frigidaire Refrigerator Start Device and what does it do?
The 241941005 is a compressor start device (sometimes called a start relay or start device module) used on many Frigidaire refrigerators. Its job is to give the compressor motor an initial boost or proper phase-shift at startup so the compressor can begin turning; once the compressor is running the start device either opens or changes its electrical characteristics so the motor continues on the run winding only.
What are the common symptoms of a failing 241941005 start device?
Typical symptoms include: the compressor humming but not starting, repeated clicking or frequent start attempts, no cooling while lights and fans work, or the compressor starting intermittently. In some cases a failed start device will cause the refrigerator to trip a circuit breaker. these symptoms can also be caused by a locked compressor or other control faults, so the start device is one likely cause but not the only one.
How can a technician test the 241941005 start device with a multimeter?
With power removed, visually inspect the device for burn marks or melted plastic. Many start devices have 2-3 terminals (common, start, run) – check continuity between terminals with an ohmmeter; an open circuit where there should be continuity indicates failure. Also check for a short to ground (low resistance from any terminal to the chassis). For more definitive testing compare measured resistance to factory specifications or substitute a known-good module. Live-voltage checks (measuring voltage at compressor terminals during a start attempt) can also indicate whether the relay is being energized – those live tests should be done only by qualified technicians using proper safety procedures.
Can I replace the 241941005 start device myself, and what safety steps should I take?
Yes – replacing the start device is a common DIY repair because it is external to the sealed refrigerant system. Safety steps: unplug the refrigerator before touching electrical components, avoid touching energized circuits, discharge capacitors if present, and observe anti-static precautions if recommended. Work behind the refrigerator access panel near the compressor; no refrigerant recovery is needed for this part replacement.If you are uncomfortable with electrical work,hire a qualified appliance technician.
Where is the 241941005 start device located on the refrigerator?
it is typically mounted on or adjacent to the compressor near the rear bottom of the refrigerator, behind the rear service panel or lower kickplate. On many models the start device clips onto the compressor terminals or sits in a bracket next to the compressor. Refer to your model’s service manual or parts diagram for the exact location.
Is the 241941005 compatible with my Frigidaire model, and how do I verify compatibility?
Compatibility depends on the refrigerator model and compressor type. Verify compatibility by checking the refrigerator model/serial number against the parts lookup on Frigidaire/Electrolux’s official parts site or a reputable parts supplier, or by matching the OEM part number (241941005). Do not rely only on physical appearance; confirm electrical terminal configuration and mounting style match your compressor.
How much does the 241941005 start device typically cost and should I buy OEM or aftermarket?
Prices vary by supplier but OEM start devices are commonly in the low tens of dollars (often roughly $10-$50). Aftermarket equivalents may be cheaper but can vary in quality. For best reliability, use an OEM part or a high-quality aftermarket part specifically listed as compatible with your model. Check seller reviews and return policies.
If I replace the 241941005 and the compressor still won’t start, what should I check next?
If replacing the start device does not restore compressor operation, check: supply voltage at the compressor terminals during a start attempt, the compressor’s electrical continuity and resistance (run winding, start winding, and return), overload protector condition, and refrigerator control/thermostat operation. A locked or internally failed compressor will not start even with a good start device and may require compressor replacement by a licensed technician. When in doubt, contact a qualified appliance service technician for further diagnosis.
