The 241941003 Frigidaireâ Refrigerator Relay Starter⤠is a compressor start relay assembly used on many Frigidaire refrigeration â¤units.It is a low-voltage control device-implemented as either a bi-metal/PTC element⢠or a relay-type module depending on the specific design-that provides a temporary electrical â¤path to the compressor’s start winding â¤(or engages an associated start capacitor) during the motor’s initial energization phase.
Inside the appliance, the relay starter interfaces directly with the singleâphaseâ hermetic compressor, the thermostat or control board â¤that calls for coolingand the compressor’s overload protector. Its primary function â˘is to alter â¤the motor winding configuration or introduce additionalâ starting impedance long enough to generate the torque required to overcome rotor inertia; once the motor reaches running speed the device opens or drops out and the compressor continues on its run winding. Because it governs inrush current and starting torque, the relay starter has a direct effect on compressor reliability, electrical load on the circuitand overall cooling performance. â˘Physically it is indeed âtypically mounted âto the compressor housing or plugged into a relay socket located at â¤the compressor terminals in household refrigerators,freezers,and similar refrigeration appliances.
In this article readers will find a technical explanation of how the 241941003 relay âŁstarter functions, guidance on compatibility and partânumber â˘matching, common failure modes and observable symptoms (for example â¤humming, repeated âclicking, no start or intermittent starts)and an overview âof standard diagnostic checks such as visual inspection, continuity and resistance measurementsand âvoltage verification. The piece will also cover practical replacement considerations-correct electrical⢠and mechanical fit, interaction with the overload protector andâ control electronics, safety precautions during service-and indicators that a⣠problem may require sealedâsystem or compressor-level repair rather than relay replacement.

Functional Role of the Start Relayâ in Compressor Start-up and Motor Protection
The 241941003 Frigidaire Refrigerator Relay Starter functions as the control element â˘that momentarily⣠connects the compressor’sâ start winding (or a start capacitor circuit) during the initial build-up of torque. In singleâphase⢠hermetic compressors this relay senses either âline current or motor voltage and closes just long enough to establish rotation; once the rotor approaches running âspeed the relay opens andâ the motor continues onâ the run winding alone. Relays for this application can be electromechanical current relays, potential relaysor solidâstate/PTCâtype starters; technicians should match the relay type to the compressor design because the âŁtiming and âmethod of startâwinding âengagement must be⢠compatible⤠with⢠the motor’s impedance and the refrigerator’s â˘electrical âcharacteristics.
- Common failure symptoms: humming at start, repeated tripping of overload, long crank timeor no start.
- Primary protective â˘behavior: limits duration of start winding engagement and prevents continuous âŁstart⢠current that â¤would overheat âthe motor.
- Compatibility note: intended for singleâphaseâ fridge compressors; verify âterminal layout and coil ratings against the compressor and harness.
During normal operation the relay⢠cooperates with the compressor’s automatic overload protector to prevent thermalâ damage from extended starting or stalled conditions; if the âŁrelay fails to drop out the start winding remains energized and the overload opensor if âthe relay never closes the compressorâ will not develop starting torque. For troubleshooting, check relay⣠continuity and⣠dropâoutâ behavior, observe inrush current during⢠startandâ compare relay terminals and⢠resistance âto manufacturer service data; replacing the relay with âŁanâ identical rated part is preferable to improvising with a different âtype because incorrect timing or coil characteristics can cause repeated failures or reduced compressor life.

How the 241941003 Frigidaire Refrigerator Relay Starter âOperates Within the Compressor motor Circuit
The 241941003 Frigidaire Refrigeratorâ Relay Starter is a compact electromechanical â¤component mounted at the compressor that momentarily connects âŁthe compressor’s start winding to line voltage during initial motor spin-up. When applied voltage is present, the relay⣠closes and supplies the start circuit to provide the torque required to â¤overcome static friction; once the â˘compressor reaches sufficient rotationalâ speed âthe relay opens and the motor continues on the run winding alone. The starter is separate from the thermal overload protector:⣠the relay handles timed/current-based engagement of the start winding while the overload interrupts power if â˘the motorâ overheats or⤠draws excessive current.
In service, the starter’s â¤proper operation⣠is evident âinâ starting current behavior and audible performance of the compressor. Typical failure modes are mechanical sticking or a failed coil that prevents the start winding from engaging, producing a humming compressor that fails to startor intermittent startsâ that stress the motor and trip household breakers. For compatibility and safe⢠replacement, match the⤠relay’s terminal layout⢠and voltage rating to the compressor (the common configuration interfacesâ with the C/S/R terminals). Practical troubleshooting steps include⤠verifying line voltage at the compressor, checking for a click from âŁthe relay on startand measuring amps during attempted start; â˘replacing a failed starter with⤠the same 241941003 part or an approved equivalentâ restores correct start sequencingâ and reduces starter-related stress on the motor.
- Common symptoms of starter failure: humming without compressor run, repeated start attempts, high inrush currentor intermittent operation.
- Functional features: âmomentary start winding engagement, designed to open⤠once target RPM reached, mountedâ for direct compressor⣠terminal access.

Electrical and Mechanical Failure Symptoms⤠Indicative of a Faulty Start â˘Relay
The start âdevice is âŁresponsible for supplying current toâ the compressor’s start winding long enough to produce sufficient starting torque⢠before theâ run winding takes over. The 241941003 Frigidaire Refrigerator Relay Starter is a replacement start relay used on many Frigidaire compact â˘and upright models that employ a singleâphase â¤PSC compressor; it â¤acts as an electromechanical or PTCâbased switch that momentarily connects the start winding during the high inrush period.When the relay degrades electrically (open/shorted âelement, high contact resistance) or mechanically (stickingâ contacts, debris),⢠typical electrical behavior includes repeated clickingâ without compressor rotation, âpersistent humming withâ high amp drawor nuisance tripping of the branch circuit breaker as the compressor attempts and â˘fails âto overcome lockedârotor torque. Using a relay that does not match the⢠compressor’s terminal âlayout or starting characteristics can reduce starting⣠torque and accelerate compressor â˘wear rather than restoring reliable operation.
- Repeated rapid clicking at the⣠relay or control board and âno compressor start.
- Compressor⢠hums but does not reach âfull âŁspeed; fridge temperature rises.
- Intermittent starts that succeed onyl afterâ tapping the relay or compressor housing.
- Visible burn âmarks, melted housingor aâ hot relay indicating overheating â˘or arcing.
- High inrush current orâ tripped breaker during start âattempts.
Technicians confirm a faulty â˘start relay by measuring both electrical and mechanical indicators: measure line voltage to the compressor during a start attempt, use a clamp⢠meter âto capture inrush current (expected several times the steadystate run current),â and check continuity/resistance between start/run/COMMON terminals â˘per compressor spec. A relay that clicks but never completes the start circuitor shows open/short conditions â¤on bench continuity tests, is electrically failed;⢠a relay that intermittently connects, shows⤠external physical damageor â˘produces arcing noises is mechanically compromised. Practical examples include a unit that starts only when the relay is tappedâ (indicates sticking contacts or⢠failing internal âŁelement)or a system were measured inrush is low despite correct line voltage â¤(indicates insufficient start assistance). Replace with a compatible relay and verify terminal mapping and current ratings before installation to avoid mismatches that âcan mask compressor âdamage.
| Item | Description |
|---|---|
| Symptom | Likely cause and technician action |
| Clicking/no start | Open/failing start relay or thermal overload; bench test relay continuity, check compressor âresistance, replace relay if open. |
| Humming/high amp draw | Start winding not engaged or stuck rotor; measure inrush current and verify â¤relay operation; inspect compressor for mechanical seizure. |
| intermittent start | Sticking contacts or degrading PTC; inspect relay for heatâ damage,test repeatedly,consider replacement âŁwith correct 241941003 specification. |
Replacement Considerations and installation Procedure for compatible Frigidaire Refrigerator models
The 241941003 Frigidaire Refrigerator Relay Starter is the electromechanical âŁdevice that supplies the inrush current⣠to the compressor’s start winding and then drops out to allow the motor to ârun on the main winding. In practice this component controls the brief high-torque phase required to spin the hermetic compressor past its locked-rotorâ condition; symptoms of a failing⤠relay â˘include repeated clicking, a humming compressor that will not start, âŁor intermittent starts that resolve after the â¤relay cools. Replacement considerations â˘center on matching the relay’s terminal layout, whether the unit contains âan integrated overloadand âthe electrical characteristics (start resistance and expected inrush current) compatible with the compressor motor. For example, many Frigidaire upright and top-freezer models use a three-terminal relay that connects to the compressor terminals labeled C, â˘Sand R (or M), âŁso verifying the OEM part number and pin configuration before installation prevents incorrect wiring or failure to âŁprotect the compressorâ motor.
- Verify model and part numbers against the âcompressor terminals⢠andâ mounting style.
- Visually inspect for integrated overload or separate protector and match accordingly.
- Measure compressor winding resistance and check for continuity before replacement.
- Ensure connectorsâ and clips alignâ with⤠the compressor housing to maintain thermal contact.
| Item | Description |
|---|---|
| Function | Provides momentary start winding current, then disengages to allow normal running. |
| Typical terminals | Three spade terminals: Common (C), Startâ (S), Run/Main (R or⣠M). |
| Compatibility check | Match OEM part number, terminal layoutand whether an overload is integratedâ or separate. |
Installation requires basic electrical and refrigeration service procedures: disconnect power to⢠the appliance, âaccess the compressor âby removing the rear access paneland observe the existingâ relay/overload orientation⢠and â¤wiring âbefore removal. Replace the relay with the matched 241941003 â¤or âŁan exact OEM-equivalent unit, seat any thermal overload in its clipand reattach spade connectors to âthe correct⣠terminals (C to common, S to start, R/M to run). After reassembly, restore power and⣠observe the compressor start⣠behavior-successful installation produces a single âstart click and the compressor accelerating to normal⢠running speed; persistent humming or ârepeated clicks indicates either incorrect part selection, a failed compressoror degraded start capacitors (if fitted). For a final check, measure operating⣠current â¤with a clamp meter against the compressor rating to confirm the relay is not causing excessive inrush or repeated cycling.
Q&A
What is the 241941003 Frigidaire refrigerator relay/starter and what does âit⢠do?
The 241941003 is a start relay (sometimes called a starter or PTC relay) used onâ certainâ Frigidaire refrigerator compressors. Its job is to⢠momentarily energize the compressor’s start winding so the compressor motor can get up to speed. after the compressor starts, the relay cuts the start winding⢠out of the circuit so the compressor runs on the run winding.
How âdo I know if the start relay is failing?
Common âsymptoms of a failing relay include: the compressor clicking repeatedly and not starting, a humming⤠compressor that never runs, refrigerator/freezer⣠warming up, frequent short cyclesor a burning/overheated smell near the âŁcompressor. Intermittent starting or long start times can also indicate a weak or failing relay.
Can â˘I test the 241941003 relay myselfand how?
Yes, you can do basicâ tests safely. First unplug the⣠refrigerator.⣠Locate and remove the relay from the compressor (usually a clip-on or plug-in module). Do a visual inspection for burning or melted plastic. Use a âmultimeter to check â¤for continuity where applicable-if you see an open circuit where there should be continuity the device is bad. For more reliableâ diagnosis, test compressor current with a clamp meter during⤠attempted start or swap the relay âŁwith a known-goodâ unit. Do not apply âmains power directly to the relay on the bench. If in doubt, have a qualified technicianâ test the compressor and relay.
How do I replace the 241941003 relay?
Turn off and unplug the refrigerator.Access the back lower panel toâ reach the compressor.Unplug or unclip the old ârelay/overload assembly from the âcompressor terminals (note terminal âpositions). Fit the new 241941003 so the terminals align, secure any clipsand reattach the â˘cover/panel. Restore power and observe: the compressor should start within a few seconds and the refrigerator âshould return to normal operation. Always ensure âyou purchase âŁthe correct replacement part for your specific model and follow safety procedures.
Is 241941003 compatible with all Frigidaire refrigerators?
Not necessarily. Parts compatibility depends on the refrigerator model and compressor type. Always verify⤠compatibility â˘by checking your model’s parts diagram or by cross-referencingâ the part âŁnumber⢠with Frigidaire/Electrolux âŁparts lists. Aftermarket relays and global starters exist, but using the exact OEM part or a verified equivalent is recommended.
Can I replace theâ relayâ with a hard-start kit or universal starter rather?
Sometimes a hard-start kit or universal start deviceâ can solve weak-start problems, but they are not a universal fixâ and may not⣠be appropriate for every compressor.Hard-start âkits change the starting characteristics⢠and can stress the compressor if mismatched.Only use a hard-start kit recommended for your compressor âtypeand ideally âŁconsult an appliance⣠technician before substituting â˘the OEM relay with a different starting device.
How much does the 241941003 relay typically cost and where can I buy it?
Pricing varies but OEM start relays commonly range from about $15 to $50 depending â˘on supplier and whether it’s OEM or aftermarket. You can⤠buy it from Frigidaire/Electrolux parts departments, authorized appliance parts retailersor reputable online marketplaces.⣠Confirm the part number and compatibility with your fridge model before purchasing.
If I replace the relay and⤠the compressor still won’t run,what else could be wrong?
If a known-good relay doesn’t start the compressor,possible causes include a seized or electrically failed compressor⣠(locked rotor or âopen/burned windings),a faulty overload protector,wiring/terminal problems,or a sealed-system issue. âA compressorâ that draws âexcessive current or shows open/shorted windings will need service or replacement by a licensed appliance technician – sealed-system repairs may require certified HVAC/R service and refrigerant-handling certification.
