241941003 âFrigidaire Refrigerator â˘Relay Starter is an âelectrical start relay designed for use in the compressor start circuit of â˘Frigidaire refrigeration units. As a âcompressor starter âŁdevice, it â¤temporarily⢠connects the compressor’s start winding⢠or start capacitor âduring initial motor spin-up and then disconnects âthe start circuit once the compressor reaches runningâ speed;â physically it is indeed commonly suppliedâ as a small module or relay assembly intended âto mount â¤near the compressor or inside â˘the âŁappliance rear accessâ area.
Inside the appliance, theâ relay âstarter functions as partâ of theâ electrical startingâ system âŁand interacts directly with the compressor, the start âand/or run windings, any start capacitor present,â the overload protectorand the refrigerator’s control/thermostat circuit. It is activated⢠when the control⤠system âcalls âfor cooling andâ supplies⢠the additional torque required at startup while â˘limiting prolonged inrush; a correctly functioning starter reducesâ start stress⣠on â˘the compressor and âcoordinates with⢠the overloadâ device to⢠preventâ sustained lock-rotor conditions or âexcessive current draw.
In⣠this article readers will⢠find a technical overview of how the 241941003 âŁrelay âstarter⢠operates,guidance âon compatibility and selection â(matching electrical ratings and mounting to specific compressor models),common failureâ symptoms⢠to watch for (for exmaple a ânon-starting â˘compressor,sustained humming,tripped breakers,or rapid cycling),step-by-step troubleshooting âmethods including basic âelectrical âchecks and bench tests,and practical replacement considerations such⢠as safety â˘precautions,verifying associated⤠overload or capacitor health,and ensuring correct wiring âand mechanical fit âŁduring installation.

Function â˘and Role of theâ Relay Starter in Compressor âStart-Up and⤠Overload â˘Protection
The 241941003 Frigidaire Refrigerator Relay Starter â¤is a start-relay and thermal-overload âdevice âused with single-phase â¤hermetic refrigerator⤠compressors. Its electrical function is to provide a â¤temporary âconnection â¤to the compressor’s start winding duringâ motor spin-up, then remove that connection once â¤the motor reaches running speed; â¤the integrated thermalâ overload âopens the circuit if the compressorâ draws sustained excessive current or âthe motor temperature rises beyond safe âlimits. Inâ practice⢠the⣠relay reduces mechanical and electrical stress at start and acts as a safety cutoff to prevent winding insulation damageâ and⢠locked-rotor overheating.
In⣠normal operation the⤠relay produces a brief audible click and allows the compressor to accelerate to operating RPM; the overload remains closed unless a fault condition â˘develops. Compatibility requires⣠matching the ârelay’sâ terminal âconfiguration, rated supply voltage (commonly 115-120 V in North American âmodels),â and physical mountingâ to the âŁcompressor orâ cabinet. when diagnosing a⤠failed start or âoverload âprotection, confirm âcorrect wiring, â˘measure line and start-winding voltages during attempted start, âand replace âthe âŁrelay only⢠with a component that meets the original specifications to maintain proper start timing and thermal trip characteristics.
- Common symptoms of relay âŁor overload failure: continuousâ compressor âhumming,no start attempts,rapid cycling,or trippingâ of branch circuit⤠protection.
- Quick troubleshooting checks:â listen⢠for click at power-on, â˘measure compressorâ currentâ during âŁstart,â and â˘inspect âfor burn marks or⢠meltedâ terminals.
- Installation note: use the âsame terminal layout and voltage rating; incorrect substitution can cause inadequate start torque orâ nuisance trips.

How theâ 241941003 Frigidaire Refrigerator⣠Relay Starter works Inside the Appliance
The 241941003 Frigidaire âRefrigerator Relay Starter âis a âstart device that momentarily applies extra âŁtorque to⢠the compressor’s start⣠winding so the singleâphase motor â¤can overcome static friction and begin rotating. Inside a refrigerator electrical⣠compartment this âŁassembly frequently enough combinesâ aâ relay or⣠PTC start⢠element with an overload âŁprotector; âthe start⢠element supplies âthe higher current or altered phase to the âstart winding and then opens or drops out once the compressorâ reaches ârun speed.Mechanically and electrically,the unit is matched to Frigidaire compressors with singleâphase PSC motors-using âthe specified terminals and mounting arrangement ensures âtheâ relay engages and disengages at the correct time and current load â˘for reliable âstarting and protection of the âcompressor windings.
Functionally, the relayâ behaves asâ a âŁshortâduration bridge between the start andâ run circuits: â˘when line voltage is âapplied, theâ relay connects the⢠start windingâ (or allows a boostâ through â˘a PTC) until backâEMF andâ centrifugal switch action or the relay’s own⣠sensing mechanism removes âthe âstart path. Technicians âdiagnose failures by observing â¤symptomsâ and performing targeted tests:â a clickingâ relay with â˘no compressor spinor⢠a â˘warm, burnt relay âŁcase, indicates the starter isn’t supplyingâ or droppingâ outâ properly; an âŁinâcircuit continuity âŁcheck⣠and verification⢠of â¤terminal behavior during a⣠start attempt can confirm whether âthe starter or the âcompressorâ motor is at fault. Replace⢠this componentâ only⣠with the same part âŁnumber or an â˘approved equivalent âŁto preserve timing characteristics â¤and overload protection; âswapping with a different relayâ type can result⢠in poor starting torque⤠or nuisance â˘tripping.
- Common symptoms: ârepeated clicking on âstart, humming without pump-up, heat at âthe relay,â or⤠compressor that runs intermittently.
- Quick tests: visual inspection,â checkâ for continuity between start/run⤠terminals,⣠observe ârelay⢠behavior âduring aâ start attempt (power applied, then⢠dropâout).
- Compatibility note: use the exact 241941003⣠replacement or a â¤manufacturerâapproved equivalentâ to match âŁcompressor⤠starting âŁcharacteristics.

|---|---|
| Function | Provides shortâduration start âtorque by connecting the start winding or using â˘a PTC element, then disconnecting once the compressor reaches speed. |
| Common tests | Visualâ inspection, terminal âcontinuityand observing⤠dropâout during an energized start attempt; consult service manual for terminal identification. |
Commonâ failure Symptoms and Measurable Diagnostic Indicators of a Faulty Relay Starter
The â¤241941003 Frigidaire Refrigerator⢠Relay Starter âis⤠a âŁswitching device that â¤briefly energizes the compressor’s start â¤winding (orâ engages a solid-state start circuit) to produce the torque required for rotor acceleration. When⤠theâ relay fails, the compressor may only â˘hum, âclick repeatedlyor fail to âŁspin up, producing elevated cabinet âtemperatures and extended run attempts as the system repeatedly tries to start. As âthe relayâ sits between theâ lineâ supply and theâ compressor start terminal, its failureâ modes-open⤠circuit, high contact resistanceor intermittent conduction-can mimic a seized compressor or a bad â¤run capacitor; technicians should interpret symptoms â¤alongside measurable electrical values ratherâ then relying on audible cues alone.
- Audible/operational symptoms:⣠repeated clicking at start, prolonged⢠humming without â¤rotation, frequent short⣠cyclingor no compressor activity while lights and fans remain powered.
- Electrical indicators: open âor intermittent continuity between relay start â˘and common terminals, abnormal voltage drop at the â˘start terminal during crank attemptsand⣠a start current that âfails to rise to expected âŁlocked-rotor levels.
- Physical signs: âoverheatingâ of the relay housing, burn marksor loose/melted terminals âindicating contact⢠failure or shorting.
Diagnosing aâ suspect relay starter requires simple bench and in-situ measurements: check continuity and compare toâ the manufacturer’s âservice specifications,observe line voltage at the relay while initiating a⤠start cycle,and measure inrush current with⤠a âclamp metre â¤to âŁconfirmâ the start⢠winding⢠is being⤠energized. A correct â¤functioning relay will present continuity â¤where specified, â˘apply ânear-supply voltage to âthe âŁstart â¤terminalâ during the brief â˘crank period, â˘and allow a transientâ inrush current significantly higher than steady-state ârunâ current; deviations indicate contact â¤resistance, thermal⣠element â˘degradation, â¤or internal â˘electronic failure. Practical troubleshooting workflow âincludes isolating power, confirming relay terminal wiring matches⣠the schematic for the âŁappliance model, swapping with⤠a known-good relay when availableand correlating electrical⣠readings with compressor behavior before replacing the compressor or other system â˘components.
| Item | Description |
|---|---|
| Continuity test | Use an ohmmeter â˘across âstart/common⣠terminals; expect continuity per⣠service spec-open âcircuit indicates failure. |
| Voltage⣠during â¤crank | Measureâ voltage at the start terminal⤠while attempting to start; significant drop or no voltage suggests relay isn’t closing. |
| Inrush/start current | Clamp-amp measurement during startup âshouldâ show a transient higher than ârun current; absence âimplies start â˘winding not engaged. |
Compatibility, Replacement Considerations,â and Step-by-Step Installation Guidelines for Frigidaire âModels
the⤠241941003 Frigidaire⣠Refrigerator Relay Starter is a âstart device designed to deliver â˘a⢠short-duration current path to the compressor’s start winding so âthe hermetic motor âdevelopsâ sufficient âtorque âŁto⤠come up⢠to â¤speed.⣠In â¤service it â¤typically mounts at âŁthe âcompressor â˘terminal cluster or insideâ a service module and works in concert with an overload protector; the relay⣠conducts âŁthe higherâ inrush current required for starting and â˘then opens (mechanically or electronically) once the motor â˘reaches⣠running â¤speed. Compatibility depends on electrical ratings (typically 115-120 VACâ for âŁNorth American models),terminal⢠configuration (two-⤠or three-terminal â¤compressorâ pins),and physical mounting-matching the â¤OEM part number âensures correctâ thermal âand mechanical fit â¤and â˘also proper interactionâ with the â¤compressor’s overloadâ device and wiring harness.
when â˘replacing the starter,â confirm the replacement matches the âoriginal’sâ voltage rating, terminal layoutand⤠mounting method; substituting a relayâ with different trip â¤characteristics or weaker contact capacity âcan result in poor starting â˘performance or âŁpremature failure.For practicalâ installation: disconnect mains power, â˘access the compressor terminal area,⤠note or âphotograph connector positions, âremove the old relay and inspect the overload for heat damage, â˘install the 241941003 part â¤ensuring tight, corrosion-free connections,â and restore power to observe start âŁbehavior and steady-state current. â˘If the compressor âŁstill struggles to start or⢠the new â˘relayâ clicks and drops out repeatedly,test the compressor windings and the overload â¤with an ohmmeter andâ measureâ operating current-theseâ diagnostics âŁdistinguish a bad âŁrelay from a⤠failing compressor motorâ orâ a seized mechanism.
- Disconnect power and verify zero⤠voltage â¤before touching components.
- Document terminal positions⢠(common,â start, run) before⣠removal.
- Inspect the â¤overload protector and replaceâ it if brittle or⢠discolored.
- Use the OEM â241941003 or an exact-rated equivalent for voltageâ and âterminal âtype.
- After installation, observe initial start âand⢠measure running current toâ confirm âŁnormal operation.

Q&A
What is the 241941003 Frigidaire refrigerator relay starter and what does it âŁdo?
The 241941003 is a compressor start device (commonly⤠called a start relay or starter). Itâ helpsâ the refrigerator compressor’s start winding â˘receive the âextra⢠current⣠needed to get the compressor⢠motor up to⤠speed. Some versions⤠are â¤a PTC âstart device, others are relay/overload⣠combinations – in âallâ cases the part’sâ job âis to allow âthe⤠compressor toâ start reliably and then⤠drop out so the compressor runs on the run winding.
What symptoms indicate⢠the⣠241941003 relay starter has failed?
Common âsigns of a bad start relay â¤include: compressor notâ starting (humming or clicking but⢠not running),â refrigerator not âcooling,â compressor ârepeatedly trying to start and then stopping,â high compressor temperatureor the relay making ticking or buzzing noises.Intermittent âstarts or tripping a circuit breakerâ are also possible. These â¤symptoms â˘can also be âcaused by other issues, so âfurther checks âare required.
How can âŁI testâ the relay âŁstarter to confirm â˘it⣠is⣠bad?
First,â disconnect power. Remove the⤠relay from the⢠compressor âand inspect visually for âŁburn⤠marks, melted plasticor a loose/rattling âŁinternal⤠part (a rattleâ can indicate⤠internal failure).⣠Use a â¤multimeter: check⤠continuity between the appropriate â¤terminals â(consult the compressor terminal markings: âC,â R,⤠S).Aâ PTC⢠relay will notâ measure â˘like a simple âresistor â˘but can still show âan open âor short.The most reliable field test â˘isâ swapping⢠with â¤a known-good relay⢠(if⣠available) or momentarily⤠supplying start power via a proper jumper/test method performed byâ a âtechnician. If the unit runs withâ a known-good relay, the original relay⢠isâ bad.â If â¤unsure, haveâ a qualified technician perform âŁthe electrical tests-compressor terminals carry hazardous voltages and âcan be damaged if mishandled.
can I â˘replace⢠the relay starter â˘myself and âŁhow do I do it safely?
Yes, replacing the relay⤠is often â˘a user-serviceable repair, but observe safety âprecautions. Unplug the refrigerator first. âLocate the relay/overload assembly on âthe side or bottom of the compressor or inside⤠the rearâ access panel, remove⣠the old unit from the⤠compressor terminals (note terminal positions)and âŁinstall âthe⤠new âpart with⢠theâ same terminal arrangement.⢠Secure it in the same position. âAfter reassembly, restore power and observe⣠operation. If you are not comfortable working around compressor terminals or the unit still fails to start, call a qualified appliance âŁtechnician.
Does âthe 241941003⣠include an overload protector or âŁis âit only a start relay?
Someâ replacement âparts with this number are sold as a combined start relay andâ overload protector, while others may âŁbe only the start device.â The⢠exact configuration depends⢠on theâ supplierâ and the refrigerator model. Alwaysâ verify the product âdescription â˘and compare the connector arrangement and mounting âwith the old part toâ ensure⢠you have the correct combined unit if the original used an overload.
How do I confirm compatibility with âŁmy âFrigidaire refrigerator âmodel?
Use yoru refrigerator’s full model number (found⣠on â˘the interior âwall or door jamb) to lookâ up parts. Check the OEM part cross-reference and âcompare terminal layout and mounting style to the part you are replacing. Many parts sellers provide⢠“fits” lists; when âŁin doubt,contact Frigidaire or an authorized parts dealer and provide your âŁmodel number⢠to confirm compatibility.
Is it worth replacing the relay starter or should the⣠compressor be replaced â˘too?
Start relay failures are common âŁand âŁinexpensive to replace; it is indeed âgenerally worthâ replacing a failed relay âfirst.If the compressor runs⢠normally after âŁthe relay replacement and⤠the ârefrigerator âcools âcorrectly, âno further action is âneeded. However,â if the compressor still will not start, âhums continuously, âor rapidly overheats even with aâ good relay, the compressor orâ other⤠components (sealed system fault, start capacitor âŁif present, control⢠board) may⤠be failing and require professional diagnosis. âIf âthe compressor âŁis seized or has an internal electrical⣠fault, replacing âŁtheâ compressor is âcostly and âmay âinfluence the â¤decision to ârepair âŁor replace the refrigerator.
The Way⣠Forward
The 241941003 Frigidaire refrigerator relay starter is a âsmall but essential electrical â˘component that âassists the â˘compressorâ during startupâ by managingâ the initial âŁcurrent and ensuring reliable motor engagement. Its proper functionâ is critical to the ârefrigerator’s cooling cycle;⤠when the relay starter operates correctly, the compressor can âstart⣠smoothly, maintain â˘appropriate temperatures,â and âreduce undue stress on other system components.
Because symptomsâ of a failing relay â¤starter-such as intermittent cooling, humming, clicking,â or a compressor that will not start-can also indicate other issues, proper âdiagnosis is âcrucial before replacing the part. Accurate troubleshooting helps avoid needless â¤expense and ensures the true root cause is addressed. âWhen testing indicates âŁthe relay starter is defective,timely replacement with theâ correct part helps ârestore performance,prevent further damage to â¤the⣠compressor,and maintain energy â˘efficiency.
For bestâ results, âŁreplacements â¤shouldâ follow manufacturer specifications and safety â˘practices; if there is uncertainty⤠about diagnosis or installation, consulting a â˘qualifiedâ technician reduces⢠risk and preserves applianceâ reliability. Regular attention toâ symptoms andâ prompt corrective action will âhelp extend the â˘service life of â˘the refrigerator and maintain consistent âŁcooling performance.
