241941005 Frigidaire Refrigerator Start Device is a compressor start component used on singleâphase refrigeration compressors to â˘assist initial⤠motor rotation. The part is a start relay/starting device-either an electromechanical relay or an electronic start module depending on the variant-designed to âmomentarily engage the âcompressor’s start winding (adn in some systems a start capacitor) to provide the additional torque required toâ bring the motor up â˘to operating speed. As a discrete component itâ is compact, intended for mounting at or near⢠the compressor terminalsand identified by â˘its OEM part â¤number for modelâlevel replacement and compatibility⤠checks.
Within the appliance, the start device sits in the compressor start circuit and directly interacts with the compressor windings, the overload protectorand the refrigerator’s power source⢠or control board. During startâup it connects the start winding (or shapes the starting current) for a â˘brief interval, then drops out once the motor reaches runningâ speed so that only the run winding remains energized.Proper operation of the start device affects inrush current,startingâ torque,and thermal stress on the compressor; it âthus⢠plays a direct role in reliable compressor starts,energy draw during âstart,and protection against stalled starts or sustainedâ highâcurrentâ conditions.
This article will explain the functional â¤principles of the 241941005 start device, identify the compressor types and appliance models where it is typically usedand describe common failure symptoms such as prolonged humming, failure â˘to start, frequent trippingor abnormal current draw. It will outline systematic troubleshooting checks a technician can perform-visual inspection, terminal and coil resistance checks, observation of relay engagementand basicâ voltage/current diagnostics-and willâ discuss âŁreplacement considerations including verifying part compatibility, correctâ mounting and wiring, safety precautionsand when to replace the start device versus diagnosing downstream compressor faults. The goal is to give technicians,engineers,and informed âappliance owners the technical context needed to diagnose and make informed decisions about this component in refrigeration service.

function and Role of the Start Device in Frigidaire Refrigeration Systems
The 241941005⤠Frigidaire Refrigerator Start Device is an electrical accessory that momentarily energizes⣠the compressor’s start winding to â¤produce the initial torque required for rotor acceleration. Technically,the start device either provides a temporary change in circuitâ impedance (as a PTC thermistor) or closes a start⤠contact â(as an electromechanical⤠relay) to introduce phase shift and boost starting current; once the compressor reaches running speed the device âŁremoves the start winding from the circuit. Proper operation depends on matching the device’s electrical characteristics (voltage rating, resistance/time constant or contact rating) and terminal configuration to the specific compressor used in Frigidaire models so that the start pulse timing and currentâ limits are correct for reliable starts without overloading the motor protector.
- Common symptoms of âŁa failing start device: compressor hums but does notâ start, repeated clickingor intermittent starting followed by â˘thermal overloadâ trips.
- Typical behaviors: provides a short-duration boost, then drops out; may self-reset if it is a PTC device or operate as a single-cycleâ contact closure if it is â¤a relay.
- Practical checks: verify presence of âvoltage at start/run/common terminals during start attempt and compare winding resistances to service specifications.
For repair âand compatibility, replace with the exact part number or an OEM-specified equivalent âthat matches terminal layout and electrical ratings; a visually similar âcomponent with different time/current⤠characteristics can leave âŁa â˘compressor sluggish to start or cause⣠nuisance overloads.⣠In maintenance practise,technicians will isolate the start device,measure its resistance or continuity,and observe the compressor’s âŁvoltage/current waveform during crank âto confirm malfunction; such as,a functioning start device will show a short-duration path to the start winding during initial mains application,while a failed open device shows no start circuit engagement. Installing⣠the correct 241941005 unit or its exact equivalent preserves intended start torque and protects the motor protector and capacitor âfrom abnormal stress.

How the 241941005 Frigidaire⢠Refrigerator Start Device Works Inside the Appliance
The 241941005 Frigidaire Refrigerator start Device functions as the compressor start assist in a singleâphase refrigeration system, briefly routing additional current to the compressor’s start winding ⤠duringâ motor startup so the rotor develops sufficient torque to turn.In OEM installations this component may be implemented as a PTC thermistor pack or an electromechanical/electronic relay; in either case its â˘role is to apply start current only for the few âtenths of a second required for the motor to âreach nearârun speed, then remove that current to prevent overheating andâ allow normal run winding operation.
Inside the appliance⢠the start device is typically mounted on or near the compressor shell or inside the control housing and connects directly to the compressor’s terminal splice. Compatibility is generally limited to â¤Frigidaire â˘unitsâ that âuse the same compressor family and âterminal configuration; confirming cabinet modelâ and compressor part numbers ensures a proper replacement. Technicians diagnose âstart device faults by observing startup behavior (repeated clicks, long humor⢠failure to start), measuring resistance/continuity at the start terminaland checking for excessiveâ inrush; replacing the start device often resolves hardâstart symptoms faster than swapping compressors, but verify compressor âwinding integrity before declaring a final repair.
- Common failure symptoms: repeated clicking at startup, extended humming without spin, compressor running hotor a unit⣠that won’t restart after an overload trip.
- Typicalâ tests: continuity/resistance check, comparison to OEM specificationand functional swap with a known good start device.
- Installation note: ensure correct â¤terminal arrangement and secure mounting to minimize vibration and heat transfer to the component.

Common Failure Symptoms andâ Diagnostic indicators of â˘a Faulty Start Device
The 241941005 Frigidaire Refrigerator Start Device functions as the starting aid for theâ compressorâ motor byâ momentarily connecting the start winding or engaging a PTC/relay element untilâ the compressor reaches running speed. When properly matched to the compressor’s voltage and start torque requirements,the device delivers the brief surge of current needed for reliable start-up; mismatched or degraded units will reduce starting torque,alter inrush current behavior,or fail to âopen/close at the correct â¤time. In practice,technicians should verify that replacement units share theâ same electrical ratings,connector type,and âmounting footprint as the original part because an âincorrect start device can allow the compressor to overheat,drawâ excessive âcurrent,or experience premature wear despite appearing to fit physically.
- Compressor hums butâ does not start (repeated attempts or long run-ups).
- Audible clicking⢠or rapid cycling at the relay/connection point when the compressor should run.
- Start device becomes unusually hot to the touch âŁor shows burn/discoloration on⢠terminals.
- Refrigerator⣠cools poorly despite âcompressor motor receiving power,⤠or the breaker/fuse⣠trips on start.
Diagnostic steps include a visual inspection for burned contacts,checking continuity and âŁinsulation resistance of the âstart âdevice per the service manual,and measuring compressor starting-current with a clamp meter to confirm excessive inrush⣠or repeated start attempts.â A practical bench testâ is to swap the suspected part with a known-good unit of⤠identical specificationâ or to momentarily assist the compressor rotor (manual spin or start capacitor where applicable) to determine whether the start device is the limiting â¤element.Documented symptoms,measured âŁcurrent and resistance values,and comparison to the compressor manufacturer’s start specifications provide the most reliable evidence before replacing the component.
| Item | Description |
|---|---|
| Humming without start | Insufficient start torque; start device likely failing to⤠supply start winding or engage âŁcorrectly. |
| Intermittent starts/clicking | Thermal or â˘mechanical failure inside relay/PTC; intermittent âcontact orâ delayed drop-out. |
| Overheating or discoloration | Internal short or high resistance at terminals; âreplace ratherâ than attemptâ repair. |
Replacement Considerations and Installation Procedures for Frigidaire Compressor⢠Start Devices
The 241941005 Frigidaire Refrigerator Start Device is a small control module used on singleâphase hermetic compressors to provide a âŁtimed⣠or conditional connection to the compressor’s start winding during initial rotation. It functions byâ introducing additional starting torque-either by switching a start âcapacitor or by shortâterm connection of the start winding-and then removing that connection when the⣠motor reachesâ running speed. Common implementations⤠include PTC âŁthermistor relays and electromechanical âŁstart relays;â the technician must confirm which⣠type is fitted because sensing behavior, thermal limitsand failure modes differ. Fault symptoms⣠that point to a⤠failed start device include compressor humming without starting, elevated inrush current that does not drop after a⤠few â¤cyclesand intermittent starts that clearâ after the device cools. Compatibility depends on matching the device’s electrical ratings,â terminal patternand whether the component is integrated with an overload protector or supplied as a separate module.
- Safety:⢠always disconnect mains⢠and record wiring before removal.
- Confirm part number and⤠terminal layout against⢠the original assembly.
- Measure coil continuity and resistance; compare to OEM reference values.
- Prepare test equipment: clamp meter for inrush, multimeter for continuity, âŁand a correct replacement⣠rated for coil voltage and thermal duty.
| Item | Description |
|---|---|
| Function | Engages start winding or capacitor briefly to achieve compressorâ startup |
| Typical âsymptom | Compressor hums but will not accelerate to normal RPM; high sustained inrush |
| Compatibility note | Match terminal configuration, coil voltageand whether startâ device and overload are integrated |
Installation requires âmethodical verification rather⢠than force-fitting parts: after â¤disconnecting âpower,⣠photograph and label wiring, then remove the old device and inspect the mounting interface and terminal spacing to ensure physical fit. Install âthe replacement so the terminals align without stressing spade connectors, secure any mounting⢠clipsand ensure an âŁintegrated overload (if present) âis âproperly seated; loose connections increase resistance and heating. Reapply power and observe start behavior with a clamp⣠meter-normal operation shows a high transient inrush that fallsâ to âŁrated running current within a few seconds; sustained high current⣠indicates a locked rotor, incorrect partor refrigerantâ fault that should be âinvestigated âbefore assuming the start device failed.
Q&A
What is the â241941005 Frigidaire Refrigerator Start Device?
The 241941005 is the OEM start device (start relay/PTC) â¤used âonâ some Frigidaire refrigerators. It provides aâ timed or instant boost to âthe compressor start winding so âthe compressor can start turning. It is not the run capacitor – it is specifically part of the compressor starting circuit.
what symptoms indicate the start device has failed?
Common symptoms include: compressor humming but not starting, fridge not â¤cooling while the compressor does not run, repeated clicking or rapid on/off cycling, unusually hot compressor⤠area or a burning âsmell near the relay, âand the fridge running only when⣠manually nudging the compressor to âstart. These suggest theâ start device or overload is not engaging the start winding properly.
How can I test⣠the 241941005 start device with âa multimeter?
Unplug the refrigerator first. Remove the startâ device from the compressor terminals.â With a multimeter set to resistance (ohms), check for continuity between the device terminals – you âshould see continuity through the overload section and âreasonable lowâ resistance in the start circuit (exact values vary). A completely open circuit (infinite resistance) or short to ground indicates failure.For definitive diagnosis a technician frequently enough uses a âcurrent draw test â¤on the compressor or substitutes a known-good startâ device.
Is the 241941005 the same as a⢠hard-start kitâ or start capacitor?
No. The 241941005 is typically a PTC start device or start â˘relay/overload assembly designed â¤for the specific compressor. A hard-start kit or start capacitor is a different aftermarket solution that adds extra starting torque (capacitor and potential relay) and is used when compressors are⢠marginal or to retrofit systems that lack sufficient starting torque.Use⢠the⤠correct part recommended for your model unless you understand the system⢠implications.
How⤠do I replace the⤠241941005 start device safely?
Always unplug the refrigerator before servicing. â˘Locate the compressor â¤access panel in the back or bottom, pull the start âdevice off the compressor terminals (it usuallyâ clips on)andâ disconnect any âretaining âŁclip or wiring harness. Install the new OEM start⤠device onto the same terminals and secure it. Reinstall the access⣠panel and restore⢠power. If you are uncomfortable working near the compressor â¤or cannot identify âŁterminals,⢠hire a qualified technician.
How do I âŁconfirm the 241941005 is compatible with⤠my refrigerator model?
Check your refrigerator’s model number (on the data plate) and consult the Frigidaire parts list or official parts diagramâ for that model. Enter either the⢠model number or the part number on Frigidaire’s parts website or a trusted⢠parts supplier to verify compatibility. If in doubt, contact Frigidaire support or provide the âŁmodel number âto a parts technician – do⤠not assume fitment based only on similar compressor appearance.
Can a failed start device damage the â˘compressor?
Yes. Repeated failed⤠starts can overheat and damage the compressor windings or shorten compressor life. A failed start device that allowsâ the compressor to run under high current or to cycle excessively can also stress the electrical system. Replace⤠a faulty start device promptly to avoid further compressor â¤damage.
Where can I buy a replacement 241941005 and does it come with a warranty?
You can buy the 241941005 OEM âŁpart from Frigidaire/Whirlpool parts dealers, authorized appliance parts retailersor reputable online parts stores. Aftermarket equivalents are also available but verify they match theâ OEM specifications. Warranty terms vary by⤠seller – many partsâ vendors offer limited warranties (30-365 days). Keep your receipt and confirm the â˘warranty period before purchasing.
