241941005 Frigidaire Refrigerator Startâ Device is a compressor start âcomponent used on Frigidaire â˘refrigeration âŁunits; it⣠is the electromechanical or solid-state⣠device that controls âthe initial current to the compressorS start winding â˘so the hermetic motor can achieve rotation âŁfrom standstill. In practical terms this start device may take⤠the form âof âa PTC relay, a start relay/overload assembly, âor âŁan integrated electronic starterand â¤it âis indeed âŁspecified by part⣠number to match the electrical and mechanical requirements of particular compressor models.
Inside the appliance âthe start device is part âof the compressor motor circuit⣠and directly⣠interacts with the compressor start â˘and runâ windings, the cabinet power â¤feed, the temperature control or main control boardand typically a âŁthermal overload protector.⤠Its primary function â¤is to applyâ a timed or conditional boost to the⢠start â¤winding â˘(or switch the start winding intoâ theâ circuit) only long enough forâ the rotor to come up to âspeed; correct operation prevents repeated stall attempts,reduces⣠inrush current stress,and helps maintainâ stable refrigeration cycles. As it sits at the boundary between the control⤠electronics â˘and the â¤sealed refrigeration system,its behavior affects compressor health,system⣠reliability,and overall âŁcooling performance.
In thisâ article readers âwill find⢠a technical⤠overview of how âthe 241941005 start device functions, how to verify â˘electrical and mechanical compatibility with specific compressors and refrigerator models, common failure symptoms to watch⤠for (such as âhumming, failure to start, frequent cycling, âŁor blown fuses),⤠practical troubleshooting⤠checkpoints (visual inspection,â basic continuity checks, listening âfor relay â¤engagementand measuring voltages at the compressor terminals), âand considerations for safe replacement and testing. The⤠goal is⤠to provide technicians, engineers, â˘and informed âappliance owners with the contextual details âneeded to diagnose start-related âŁfaults and select appropriate, compatible replacement âŁparts without prescriptive marketingâ or exaggerated claims.

Function and Role of⢠the Start⤠Device in âFrigidaireâ Refrigerator Compressor Circuits
The 241941005 â¤Frigidaire Refrigerator Start Device provides âthe âŁtemporary high-torque path required⢠to âspin âa⤠hermetic compressor up to operating speed. During startup the device connects the compressor’s start winding (or engages an auxiliary start capacitor circuit) to supply the additional inrush current needed toâ overcome static torque âandâ refrigerant pressure;⣠once the motor approaches synchronous speed âthe start device opens (or drops out)⢠by means⣠of a thermistor, bimetal action or current-sensing relayâ so that the compressor continues on the run winding alone. Typical failure modes are a device that fails to close (compressor will⣠hum but notâ start),or one that fails toâ open (compressor⢠runs hot and trips the overload protector),because the start element must switch reliably⤠within the first fraction of a second of operation.
Selection and replacement require⢠matching electrical âbehavior, terminal layout and physical mounting to the compressor and⢠refrigerator chassis.Technicians should verify nominal supply voltage compatibility and observeâ connector orientation and the interaction with â¤the compressor’s â¤internal overload protector before installing a replacement; many service procedures use a clamp-styleâ meter toâ measure inrush and winding⤠resistanceâ or perform a bench-start testâ to confirm âŁproper drop-out timing. âŁPractical, actionable indicators that the start device is suspect include repeated clicking with no âstart, frequent overloadâ trips,â or unusually long start attempts; addressing those symptoms⤠typically resolves hard-start conditions without replacing the compressor itself.
- symptoms: humming without start, repeated overload trips, âor intermittent starts.
- Quick âŁchecks: measure start/run winding resistance, observeâ drop-out⢠timingand inspect terminals for heat damage.
- Replacement⢠guidance: confirm voltage and connector compatibilityand verify mechanical fit in the compressor mounting clip or bracket.

howâ the âŁ241941005 Frigidaire Refrigeratorâ Start Device⤠Works Inside the Appliance
The 241941005 âFrigidaire Refrigerator â˘Start Device is âa â¤smallâ electromechanical/solid-state component that provides the temporary â¤boost required to âengage the compressor’s start winding during initial motor spin-up. Internally it acts as a time-limited connection between the run and start windings (or as a current-sensitive switch),allowing the⣠compressor to reach the â˘rotation⢠speed where âthe run winding alone can sustain operation. In manyâ Frigidaire systems this device replaces or integrates the â˘start relay and overload protection functions; technicians should match the part⢠number to the compressor’s design because mounting⣠orientation, terminal arrangementand tripâ characteristics vary between models.
Duringâ normal operation⤠the start device âcloses âfor a âfraction â¤of âaâ second at each startup and then either opens or changes impedance once the compressor is up to speed; âŁthis sequenceâ minimizes stressâ on the motor and â˘electrical circuit.⤠Failure modes include a device that remains open (compressor hums but âŁdoes â˘not start), a device âthat never opens (excessive âcurrent, overheating), â˘or intermittent operation that causes repeated ârestarts and thermal âtrips. Practical troubleshooting includes checking for âŁcontinuity across the start terminals, verifying 120 VAC supply at the compressor under âloadand swapping with a known-good 241941005 in compatible âunits; â¤always⤠use the same partâ number or a manufacturer-approved equivalent to preserveâ correct timing and âŁoverload response.
- typical behaviors:⢠momentary closure on startup,â then open/limited conduction âduring run.
- Common symptoms of failure: compressorâ hum without start, â¤frequent thermal trips, no compressor activity.
- Service ânote: confirmâ physical terminal mapping and mounting clipâ fit when replacing.

Common Failure Symptoms and Electrical Diagnostic â˘indicators for the Start Device
The 241941005 Frigidaire Refrigerator Start Device is the kick-start âcomponent âthat supplies the initial âphase shift or momentary connection to the compressor’s start âŁwinding soâ the hermetic singleâphase compressor can develop torque and run. In practiceâ this device âcan be a PTC⣠thermistor, a ârelay/overload comboor a⣠solidâstate âstarter â˘depending on the compressor and model; it does not âchange the compressor’s internal windings but must⤠match the compressor’s terminal configuration and electrical â˘characteristics to be compatible. when functioning correctly the start device engages only during the brief startup interval and then drops out; a failed or marginal start device⣠will present as repeated start attempts with audible humming, brief spins followed by stopor tripping of⤠the âoverload protector, which â˘canâ lead to âŁelevatedâ internal temperatures â¤and progressive refrigeration loss in the cabinet.
- Compressor hums but does notâ run âŁor runs âbrieflyâ then â˘stops.
- Frequent clicking or rapid cycling at startup (relayâ chatter).
- Freezer âor refrigerator temperature gradually⤠risesâ despiteâ the compressor trying to start.
- Start device overheats, shows âburn marks, âor its plastic housing is âdeformed.
- Tripped breakers or blown fusesâ on attempted⤠starts.
- High inrush current âŁon startup (seen with aâ clamp⢠meter) indicating excessive load or⣠locked rotor condition.
| Item | Description |
|---|---|
| Supply Voltage | Confirm correct line â˘voltage at compressor terminals duringâ a start attempt; absence of voltage isolates⣠control or wiring faults. |
| Continuity | Start device and startâ winding should show continuity; an open circuit in the start path indicates a failed âdevice or broken coil. |
| Start Current | Measure inrush current with a clamp meter; excessiveâ inrush suggests locked â¤rotorâ or failing start âŁsupport, while nearâzero current with full⢠supply voltage suggests open â˘start circuit. |
| Visual/Mechanical | Inspect for âŁburn marks, melted housingor loose terminals; mechanical relay contacts⣠may pit or âstick and require replacement. |
For â˘diagnostics, isolate power and verify wiring and connector fit for the specific refrigerator model before energizing tests; âthen measure supply âvoltage at theâ compressor while observing whether the startâ device engages. Use âa âmultimeter âto check âcontinuity of the start path and a â˘clamp meter to capture starting amperage; if âŁsupplyâ voltage is present but the compressor does not draw expected inrush current and only hums,â the start device is âthe likely fault and âŁshould be replaced with a compatible unit. Disconnect mains power â¤before removingâ or replacing the start deviceand when in⤠doubt benchâtest suspect partsâ against a⣠known good starter or consult compressor⣠manufacturer data to confirm terminal layouts and acceptable electrical characteristics.
Replacement Considerations and Installation Procedures for theâ 241941005 Start Device
The 241941005 Frigidaire Refrigerator Start Device is an electromechanical/thermistor-style module that provides the initial currentâ boostâ to the compressor’s start winding and then removes âthe⢠start circuit once the compressor reaches ârunning speed. In normal âŁoperation the⣠device presents low⢠impedance to allow a high starting torque, then increasesâ impedance â(or opens a relay) to prevent overheating of the start winding; failure modes commonly observed are⢠continuous compressor humming, intermittent startsor no-run conditions.Compatibility depends on â¤matching the⤠part number â¤and the compressor’s electrical characteristics (voltage, â¤locked-rotor currentand terminal configuration); replacing the start device with a physically similar unitâ that does not match⢠the compressor’s electrical ratings can produce marginalâ starting or shortened compressor⢠life.
Before âreplacement, verify the symptom and perform basic electrical checks: measure continuity⣠of⢠the start circuit, compare running and⣠locked-rotor currents âŁagainst manufacturer dataand⤠inspect for thermal damage or oil leaksâ around the⣠compressor.During installation,â removeâ power, gain access to the compressor compartment, swap âthe device while preservingâ terminal order and mounting orientation,⢠and secure any mounting brackets or insulators to avoid vibration transfer. After reinstalling, monitor theâ initial start current with âŁa clamp meter and â˘listen for⤠normal⤠start/stop behavior for several minutes; â¤such as, a accomplished installation willâ show a brief high inrush âthat falls to a defined runningâ amp value and absence of sustained humming or tripping of overload protection.
- Disconnect â¤power and wait⣠a few minutes for stored charge to dissipate before⢠touching components.
- Confirm OEM part⤠number and âterminal layout match the â¤compressor before installing.
- Test old unit for open/short and compare locked-rotor⢠amps if possible.
- Secure mountingâ and isolate from vibration; retest run current and temperature after installation.

Q&A
What is the â241941005⣠Frigidaire refrigerator âstart device and what does⢠it â¤do?
The 241941005 start⤠device is an electronic âor thermistor-based start relay that helps the compressor overcome initial âŁinertia and beginâ running. â¤It momentarily applies power⤠to theâ compressor’s start winding (or changesâ circuit characteristics) during startup,⣠thenâ drops outâ so the compressor runs on the â˘run winding.Without a functioning start device âthe â¤compressor may hum, clickor fail to start and the refrigerator âwillâ not cool properly.
What are theâ common symptoms that thisâ start â˘device âhas failed?
Common signs include: compressorâ humming but not âŁstarting, repeated clicking of a relay, refrigerator and freezer warming, â˘compressor getting very âhotor the compressor starting intermittently. If the compressor never attempts to run (no âŁclick or âŁhum) this might potentially â¤be a start device issue⢠but could also be⤠a âcontrol or power problem.
How can I test⣠the 241941005 start device at home with⤠a multimeter?
First, disconnect power to the fridge. Remove the start⢠device from the compressor terminals. For⣠a standalone⢠start device or PTC, check for continuity across its terminals with an ohmmeter;â an⤠open circuit usually means failure. If the device â˘is an electronic relay, âcontinuityâ tests may be inconclusive-look for visible damage, burningor corrosion. Also test the overload protector (if separate) for continuity.â If you see no continuity âacross the overload or the start device is physically damaged, replace âit.â If unsure, replace âthe relay/start deviceâ and overload together, as they commonly fail in pairs.
Can I temporarily bypass the âŁstart device âto get the compressor running?
Bypassing or â”jumping” compressorâ terminals âisâ not recommended for homeowners. It âcan damage the compressor and âisâ hazardous. âTechnicians sometimes use controlled methods to momentarily energize the start winding for diagnostics,but this requires knowledge andâ proper safety precautions.If â˘the start device is suspected bad, âthe correct course is to âreplace it rather than attempt a bypass.
How doâ I replace the 241941005 start device? is it âa DIY job?
Replacement⣠is a moderate âDIY job for âsomeone cozy working with appliances.⤠Steps: unplug the âŁrefrigerator, pull it away from the â˘wall, remove the compressor access cover, locate⢠andâ carefully remove the old start device from the compressor terminals, note terminalâ positions,â attach the new⢠device, reassemble the⢠access coverand ârestore power. Always â˘ensure â˘power is âoff before touching wiring and confirm the replacement âŁpart matches the original. If you’re not comfortable with âelectrical⤠work or accessing the compressor area, hire a qualified appliance technician.
Will replacing the start device fix all compressor âŁstart problems?
Not always. A â¤bad start device is a â˘common cause of start failures, but other causes include a failed capacitor â˘(in some designs), a bad overload protector, wiring âissues, a seized compressor, â¤or a control board fault. âIf replacing the start device does not restore proper starting,â further â¤diagnosis âŁof the overload,â capacitor (ifâ present), wiring continuityand compressor health will be ânecessary.
Is 241941005 compatible with my Frigidaire model,and how do I confirm âfitment?
241941005 is⢠an OEM Frigidaire start device used on âmany âŁFrigidaire/related-brand refrigerators,but compatibility varies by model and âmanufacture date. Confirm fitment by checking your refrigerator model number against the⢠part lookup on⤠Frigidaire’sâ official â¤parts site⣠or â¤an authorized parts distributoror⢠by comparing the old part’s physical shape and terminal arrangement to the âreplacement.
Should Iâ replace the overload protector orâ relay at the same âŁtime as the start device? How much⤠does the part cost?
It is good⣠practice to replace the start device and the overload protector⢠(if separate)⤠together âbecause both endure the same stress and âone failing often leads toâ the âŁother failing.â Pricing⤠varies by supplier but the start device itself âis typically inexpensive (often under⢠$50 USD OEM; aftermarket prices may be lower). Labor costs apply⢠if âyou have⢠a technician â¤perform the⣠replacement.
