241941005 Frigidaire Refrigerator Start Device is a ācompressor startā¢ component used in Frigidaireā¤ refrigeration units, typically implemented as a start relay/overload assembly orā solid-state starter that ācontrols the initial inrush current to the ā¢compressor’s start winding. As a discreteā£ electrical part,ā it is ādesigned to provide a timedā orā¤ conditional ā¢connection of ā£the startā¤ winding during motor startup and to protect the compressor from ā¤sustained overcurrent conditions; āthe device is specified for particular line voltages ā¤and motor ratings and ā¤is identifiedā by itsā¤ OEM part numberā for compatibility with matching models.
Insideā the appliance,the start ā¢device āsits in the compressorā¤ motor circuitā andā¢ directlyā¢ interfaces with the compressor start and runā windings and,where present,a start ā¢capacitor or overloadā¤ protector.It isā actuated by the thermostat or electronic controller and must tolerate ambient ā¢cabinet temperatures and vibration near the ā£compressor compartment. Proper operation of the start device ensures the compressor reachesā¢ operating speed quicklyā and without excessive current draw; conversely,aā£ faulty start deviceā£ canā prevent the ācompressor from starting,cause ārepeatedā£ cycling,or allow sustained high current that stresses the motor and supply wiring.
In this article you will find a technical clarification of the start ā¢device’s function,guidance on determiningā¤ compatibility by matching partā¢ numbersā and electrical ratings,common failure symptoms to observeā (for exampleā¢ humming,no-start conditions,frequent tripping,or āelevated current draw),and practical troubleshooting approaches for fieldā diagnosis āsuch as checking electrical continuity,terminal voltages and motor behavior. Theā¢ article also covers replacement considerations includingā confirming the correct OEM orā equivalent āpart, installation location and ā£mounting, ā¢basic safety precautions when working on the compressor ācircuitand verification steps to āconfirm aā¢ triumphant repair.

Function and ā£Role of the Start Device in Compressorā Motor Start-up and protection
The 241941005ā¢ Frigidaire Refrigerator Start Deviceā£ is aā¤ control element that momentarily connects the compressor’s start winding (or provides a phase-shifted path) to ā¤produce the extra torque required to ābring the motor up to running ā¢speed.ā¢ Inā practical ā¤installations this component canā be a PTC thermistor, an electromechanical relayor an electronic āsolidāstate starter; each type closes the start circuit āon powerāup and then opens it once the compressor reaches nearārun ā¢speed. During the milliseconds-to-seconds of startup ā¤the device senses motor āelectrical characteristics (voltage drop or coil current)ā£ and times or interrupts the start circuit accordingly to avoid continuousā¤ energization of ā¤the start winding,which would ā£overheat the motor and reduceā¤ life expectancy.
Beyond initiating rotation, the start device contributes to compressor protection by limitingā¢ inrush ā¤and preventing stalledāstartā conditionsā that draw excessive current.ā It normally works ātogether with āa separate ā¤overload protector or ā¢thermal cutoff that disconnects the compressor āwhen internal temperature or ā£current exceeds safe limits. Compatibility ā£is resolute by terminal ā£layout, ratedā voltage/currentand the compressorā¢ motor type; installing a start device withā incorrect electrical ratingsā or terminalā configuration can resultā¢ inā¤ persistent hum,ā repeated starting attempts, tripped breakersor premature compressor failure. For ā¤technicians and owners, verify the ā¢part number and electrical specificationsā¤ beforeā replacement to match the compressor’s āstarting characteristics and the refrigerator’s control wiring.
- Common symptoms of start device failure: continuous compressor hum, frequent clicking asā relays ā¤try to restart, ā£fridgeā£ warming,ā and high measured startingā current.

How āthe 241941005 Frigidaire Refrigerator Startā Device Works Inside ā¤the Appliance
The 241941005 Frigidaire Refrigerator Start Device is an electrical ā£starter accessory that provides the brief additional torque required to bring the compressor motorā from standstill to synchronous ā£running speed. in singleāphase refrigeration compressors the start device temporarily engages the compressor’s ā start winding (or inserts a lowāresistanceā pathā¢ such as a PTC thermistor or ā£relay ā¤contact) ā¤so the motor overcomes static friction and refrigerant pressure at ambientā conditions; ā¢once the motor āreaches running speed the device opensā¤ or increases ā£resistanceā¢ so ā£only the run winding remains āenergized and the steadyāstate current drops. āPhysically it ā¢mounts at the compressor terminal cluster or in an adjacent relay/overload assembly and must match the compressor’s voltage and lockedārotor current ācharacteristics to provide correct timing and cutoff behavior.
In ā£practiceā technicians ā¢observe ā¢that a failingā start device produces characteristic symptoms: a compressor that hums but does notā¢ spin up, frequent short cycling, tripped thermal overloadsorā high inrush current readings at startup. Diagnostic checks includeā visual inspection for heat damage or pitted contacts, ā¢continuity and āresistance measurements ofā the āstart pathand live voltage checks during attempted starts to confirm whether the device disengages after āthe motor accelerates.When replacing the ācomponent, select the exact part numberā¤ or an electrically equivalentā unit rated for theā¤ same compressor type and service habitat; swapping āwith a knownāgood āstart ā¢device or using ināsystem ācurrent/voltage measurements ā£provides practical confirmation that the start mechanism and overload protector ā¤are functioning together correctly.
- Common symptoms: humming without spin-up, intermittent starts, tripped breakers, increased compressor ā¢stress.
- Key behaviors: ātemporary start ā¤circuit engagement,ā timed disengagement, heatāsensitiveā£ or contactābasedā¢ switching.
- Compatibility: must ā¤match voltage and lockedārotor ācurrent of the compressor or be the OEM part number.
| Item | Description |
|---|---|
| Function | provides temporary torque by connecting the ā¤start winding or inserting low resistanceā¢ duringā¢ startup |
| Location | Mounted at compressor terminal ā¢clusterā£ or within the relay/overload assembly |

Common Failure Symptoms and Electrical Indicators of Start Device Degradation
The 241941005ā¢ Frigidaire Refrigerator Start Device is a compressor start aid āthat provides theā¤ brief additional ātorque required to overcome rotor inertia at motor startup. In practice thisā£ module or relay momentarily āroutes current āto the start winding (or modifies circuit impedance) untilā¤ the ā¤compressor reaches synchronous speed,ā£ then drops out so theā¤ motor runs on the main winding. compatibilityā depends on terminal layout,operatingā¤ voltage,and āthe āthermal characteristicsā of the original design; replacing a failed unit with an identical number (241941005) preserves the ā¢correctā¢ engagement ā£timing and overload behavior for the specific Frigidaire compressor family. Technicians should verify mounting,connector type,and nominal ratings when selecting aā substitute part to avoid ā¢premature wear or ā£improper starting behavior.
Electrical indicators of start device degradationā are bothā¤ behavioral at theā appliance and measurable with common service ātools. Symptoms you will observe include intermittent or repeated clicking at the compressor, āa steady hum without compressor rotation,ā longer-than-normal startā¤ durationsor tripped overloads; electrically, a ā£defective start ā¤device frequently enough showsā¢ open circuits, no change ā£in resistance during engagement, ā£or excessive āinrush current that ā¤exceeds normal startup profiles. Use āaā multimeter to check ā£for continuity or opens ā£across the relayā¤ terminals and āa clamp meter ā£to compare ā£startingā¢ current against ā¢a known-good unit; when measurements deviate from expected engagement behavior, replace the start device rather than repeatedly resetting āoverload protection.
- Repeated clicking or cycling at compressorā¢ start.
- Compressor hums ābutā doesā not turn (locked-rotor condition).
- High or sustainedā¢ inrush current on startup āas āmeasured with a clamp meter.
- Burnt odor, visible heat damageor melted terminals āat the startā device.
| Item | Description |
|---|---|
| Continuity test | Check for continuity between start/run ā£terminalsā¤ when device should āengage; an open readingā indicates internal failure orā¤ broken āconnection. |
| Startup ācurrent behavior | Compare measured inrush ā¢current ā¢to a known-good unit or manufacturer’s specification; excessively high or āprolonged inrush suggests the start device failed to drop out properly. |
| Physicalā£ inspection | Look ā¤for melted housing,corrodedā terminals,or discolored components-these indicate thermal or electrical overstress requiring replacement. |
Troubleshooting and āDiagnostics: Test āProcedures and Isolation Steps for Start Device Faults
The 241941005 Frigidaire refrigerator Start ā¢Device ā£ is a compressor startā£ assistā thatā temporarily modifiesā¤ the electrical path to the compressor motor during initial startup, either by providing a timed connection to the start winding (relay style) or by increasing start torque through ā¢a PTCā thermistor. In ā¢operation ā£the device must allow high starting torque ā¤for a fraction of a ā£second andā¤ then ā£remove theā¢ start assist āonce ā£the motor reaches run speed; āfailure modes ā£include open circuits,ā stuckā contactsor aā thermistor that no longer changes resistance when āhot. Compatibility matters: the start device is āmatched to compressor impedance and lineā¢ voltage, so replacing it with an incorrect type canā£ produce weak starts, ā£repeated overloadā¢ tripsor accelerated wear on the compressor. Practical āsymptomsā to log before testing includeā¢ a steady compressor hum with no start, a device that feels unusually hot after attempts āto start, repeated attempts by the overload to resetorā¤ normal fan operationā while ā£the compressor fails ā¤to run.
- Safety ā£first: disconnect mains power and dischargeā¢ any capacitors ā£before handling the start device or compressor terminals.
- Visual inspection:ā¤ check for burned ā¤contacts,ā cracked housing, ā£orā¢ melted terminals; inspect wiring and overload for ā£continuity.
- Electrical checks: āmeasure continuity/resistance ā¤between the ācommon, ā¢start andā£ run terminals; test for shorts ā¤to ground; compare behaviorā£ of the ādevice cold versusā after āa few seconds of attempted start.
- Operational isolation: verify ā¢supply voltage at the compressor during a start attempt, measureā£ inrush/starting current with a ā¢clamp meterand substitute a known-good, correctly rated ā¤start device to confirm fault localization.
| Item | Description |
|---|---|
| Continuity/Engagement | Start device should present low impedance between start and common during initial ā£engagement and ā¢then open orā change impedance when ārunning; an open circuit or no change indicates failure. |
For diagnostic clarity, combine the electrical measurements with operational ā£observations: a low ā¢or normal locked-rotor resistance āon the ācompressor windings with a failedā¤ start device points to replacing theā start device, ā¢whereas high locked-rotor ā¤resistance or a physically seized rotor indicatesā¢ aā¤ motor fault or ā¤mechanical bind. Whenā substitutingā components for a confirmation ātest, use a startā¤ device āwith identical ratings and connector layout and monitor both current and temperature during repeated startsā¤ to ensure the replacement behaves correctly; also check the overload protector and incoming ā¤supply stability because repeated undervoltage events can mimic start-device failures. Document measured values and test ā£conditions so that replacement decisions ā¢are based on repeatable dataā rather than single-event observations.
Q&A
what is the Frigidaire part 241941005 (Start Device)?
Part 241941005 is ā£aā£ compressorā£ startā device (also called a start relay/PTC or startā¤ kit) used on many Frigidaire refrigerators.Its job is to provide the compressor’sā¢ start winding withā a brief boost āor switching action so āthe compressor motor can ā¤start, āandā¤ to help protect the compressor from overheating orā£ excessive current during start-up.
What ā¤symptoms indicate the start device ā£might be failing?
Common signs include repeated clicking or ābuzzing from the back of the fridge, the compressor trying āto start then stopping (humming but not running), ā¤freezer and fridge warming up, āthe compressor repeatedly tripping the circuit breakeror higher āthanā normal electrical ādrawā¤ when theā£ compressor attempts to ā£start.
How can āI test the start deviceā£ to see āif it’s bad?
Always disconnectā¢ power āfirst.Remove the āstart ādevice from the compressor terminals and inspect itā visuallyā¢ for burn marks, melted plastic or aā¤ burnt smell.ā For electromechanical relays you canā¢ gently shake them – a loose rattling can mean failure. Use ā£a multimeter to check ācontinuity or āresistanceā acrossā the ā¤device’s terminals ā(follow the device wiring diagram if present).ā¤ If the device isā¢ open (infinite resistance) or shorted to ground, it’s bad. Note:ā¤ some PTC-styleā start devices don’tā¤ measureā¤ simply with resistance alone – if in doubt, replacement with āa known-good part is a reliable ātest. If you are not pleasant working with compressor terminals or mains voltage,have a technician test it.
Is 241941005 compatible with my āFrigidaire model?
Compatibility ā¤depends on the refrigerator model. The safest method is to check your refrigerator model number and cross-reference ā¢it with Frigidaire’s parts lookup orā¤ an authorized parts dealer. Do ānot assume interchangeability without verifying the partā£ number and terminal configuration.
Can ā¤I replace theā¤ start device myselfand how difficult is it?
Yes, replacingā a start device isā a common DIY repair for someone comfortable workingā safely around appliances. Basic steps: unplug the refrigerator, pull it away from the wall, remove theā¤ access panel on the compressor compartment, note the wiring and terminal positions, remove the old device ā¤(andā any mounting clips), install the ā¤newā£ device on the compressorā terminals, reattach paneling, āand ā£restore power. do not ā£attempt to open the sealed compressor or refrigerant system. If you’re unsure about electrical safetyā or terminal wiring, hire aā¢ qualified technician.
What tools do ā¤Iā¤ need to replace or test āthe start device?
typical tools: insulated āscrewdrivers or ānut drivers to remove access panels, needle-nose pliers to handle clips, a digital āmultimeter to test resistance/continuity, gloves and eye protection. Optionally have a replacement OEM start device on hand. Always disconnect power beforeā working on the unit.
How much does aā replacement start device cost and is āit worth replacing?
Replacement start devices are generally inexpensive: common prices for the part alone areā usually in the low ā£tens of dollars (typical aftermarket/OEM ranges might be roughly $10-$50). Labor (ifā you hire aā technician) canā add to the cost. If theā¤ fridge’s compressor is otherwise healthy, replacingā a bad ā¢start device isā¢ often an affordable and ā¢effective repair. If the compressor itself āis failing, replacing theā startā device will not fix that more serious problem.
Can a bad start device damage the ācompressorā£ or causeā further problems?
Yes.If the start device fails and the ā¤compressor repeatedly hums orā stallsā£ trying to start, theā compressor can overheat, draw excessive current, ā¤orā¤ eventually sustainā damage. Having mentioned that, sometimes ā£a failing compressor ā¢causes heavy start current that ā¤damages the start device. If you replace the start device and the compressor still won’t run or tripsā¤ breakers, stop andā call a technician to avoidā damaging the compressor.
