241941005 Frigidaire Refrigeratorâ Start Device is a compressor⣠start device supplied for use in Frigidaire residential refrigeration units;â it is indeed a small electromechanical â˘or solid-state module that assists aâ singleâphase hermetic compressor in achieving the initial torque required to begin rotation. In â˘practical terms this component functions as the startâ relay or⣠start assist â¤in the compressor start circuit and is designed to operate briefly at motor energization to engage the compressor’s start winding or to alter circuit impedance during the startup interval.
Inside the appliance theâ start device sits in the compressor starting circuit and interfaces directly with the compressor motor windings, anyâ auxiliaryâ start capacitor or PTC element present, the thermal overload protectorand the â˘refrigerator’s control system or âŁthermostat. It is indeed typically mounted on or â˘near the compressor or inside the appliance’s service compartment and is critical to reliable compressor start-up; without a functioning start device the compressor may fail â¤to start, will hum, draw excessive âŁcurrent,⣠or cycle improperly, âwhich affects âcooling performance and can stress protective devices and âthe compressor itself.
Inâ the following article readers can expect a technical examination of the 241941005â start device âcovering its operating principle, mechanical and electrical compatibility considerations, common failure â˘symptomsand practical troubleshooting techniques useful to technicians and informed owners (for example, continuity and voltage checks and observation â¤of motor starting behavior). The article⢠will also outline safe replacement considerations-including matching electrical ratings and mounting method-and diagnostic steps to distinguish a start device âŁfault from related issues such as⤠a failed compressor, blown overloador wiring/control faults; as with all service procedures, power should be disconnectedâ before inspection or replacement.

Function âand Role⢠of the Start Device in Frigidaire Compressor Start Systems
The 241941005 Frigidaireâ Refrigeratorâ Startâ Device is a⢠control component that momentarily energizes the compressor start winding to produce the phase shift âand additional torque required to move⤠the hermetic compressor from âŁstandstill to normal running speed. In singleâphase refrigeration compressors the start device âŁeither provides a timed connection (electromechanical relay) âor a temperatureâdependent resistance change â¤(PTC) to the start⣠winding; once the rotor is⢠turning and backâEMF is sufficient, â˘the device opens or drops âout to remove the start winding from the circuit. This action reduces continuous inrush current and prevents overheating of the start windingâ while ensuring reliable crankâup under typical load and evaporator conditions found in Frigidaire refrigerators.
Behavior and compatibility considerations determine service and replacement âchoices: a correctly matched startâ device must haveâ appropriate voltage rating, dropout â¤timing, âand connector styleâ to match the⤠compressor and harness. Failed start devices commonly produceâ symptoms such as ârepeated clicking, a humming compressor that will not start,â or intermittent starts under higher ambient âor load⢠conditions; technicians confirm failure by observing dropout behavior, measuringâ starting current with a clamp meteror checking resistance â¤changes on PTC types. When replacing the module, match â˘electrical characteristics and â˘mechanical mountingand⣠verify that â¤the compressor â¤itself is not seized or low â¤onâ charge âbefore concluding âthe⤠start device is at fault.
- Typical â¤symptoms: repeated clicks, prolonged compressor hum, intermittent starts.
- Diagnostic checks: clampâmeter starting amps, observe relay/coil âdropout, measure PTC resistance variation.
- Replacement considerations: voltage, connector â˘type, timing/dropout characteristicsand OEM vs. equivalent compatibility.

How the â241941005 Frigidaire Refrigerator Start device Operates Within the Compressor, overload Protectorand⢠Control Circuitry
The 241941005â Frigidaire Refrigerator â˘Start Device provides the momentary electrical path needed to⤠energize the compressor’s start winding so the motor achieves the torque required to accelerate to running speed. In the typical compressor starter circuit the start device presents a low-resistance path to the start terminal at initial energizationâ and then either opens or increases resistance once the⣠rotor approaches synchronous speed. The overload protector is wired in series with the compressor windings and will interrupt the âcommon connection if excessive â˘current or⣠temperature is detected; the start device and overload protector therefore âwork together to allowâ reliable starting âwhile preventing sustained high-current or thermal damage.â When replacing this component, match terminal layout and whether the âunit includes an integrated overload or is a separate relay/PTC module, since compatibility affects both mechanical fit and electrical timing in the control circuit.
Electrically, start devices are implemented either âas a PTC thermistor that rapidly⣠increases resistance as⣠it âŁheats or as an electromechanical relay⢠that drops out after âthe initial inrush; both implementations accomplish the same functional transition from start to run conditions. In practical troubleshooting, measure⤠voltage across the start and run terminals during a start attempt and listen for the relay action or PTC heating behavior; âsymptoms such as repeated âclicking, a humming compressor that fails to latch into runor âno inrush followed by â˘overload trips point â¤toward a failed âstart device or a bad coordination with the overload protector orâ control⣠board. Technicians should not bypassâ the overload protector-doing so removes thermal/current protectionâ and⣠risks compressor damage or fire-rather, replace the 241941005 with a unit matchingâ the OEM terminal configuration and electrical characteristics,⣠and âverify correct âbehavior⢠under load after installation.
- Common indicators of⤠start-device issues: humming without start, rapid cycling, visibleâ damage or discoloration at terminals.
- Checks to perform: continuity of overload, presence of âmomentary start voltageand âcorrect terminal identification (C, R, S).
- Replacement note: confirm whether the assembly â˘includes an internal overload or is âintended to work with an external protector.

common Failure Symptoms and Diagnostic âindicators of the âstart Device
The 241941005 Frigidaire Refrigerator Start Device is an electromechanical starter intended to assist singleâphase hermetic compressor motors with initial torque by engaging the start winding (or providing a phase shift) during the crank-up interval and thenâ removing that⣠assistance once theâ compressor is running. In practical terms the start device controls the brief high âcurrent and timing required âŁto overcome lockedârotor inertia; if the device does not open or provide⣠the designed phase shift, the âcompressor will draw excessive current or simply fail to turn. This⣠part is an OEM replacement⣠option for Frigidaire units âŁthat specify 241941005 and is compatible âwith compressors⢠that share the same start/relay configuration and terminal âlayout – confirming terminal markings and mounting style against â¤the old unit ensures correct fit and operation.
- Compressor hums but will not start, then trips the overload.
- Intermittent starts or delayed starts after a few attempts.
- Repeated âŁclicking or relay chatter at the compressor⤠terminal block.
- visual damage: burned⤠terminals,â melted⤠plasticor discoloration at connections.
- Abnormally high starting â¤amperageâ measured with a clamp meter.
Technicians diagnosing⢠failures should first isolate power and â¤perform a visual inspection of⤠connector integrity and thermal damage, then use a multimeter âto verify continuity and a clamp meter to observe inrush⢠current during a start attempt. A âfailed start device commonly showsâ open circuit on the start⢠path or excessive âresistance comparedâ with a known good⢠unit; measured â˘inrush substantially above the compressor’s normal lockedârotor current typically indicates either a bad start device or aâ mechanically impaired compressor.Practical troubleshooting steps include temporarily substituting a known good start device (or controlled hardâstart assist) to confirm the âstart device as⢠the faultand checking that the overload protector âis not repeatedly tripping – repeated short attempts can damage âthe compressor motor even if the⣠start device is intermittent.

Compatibility, Model Fitmentandâ Replacement Installation Procedures for the 241941005 Start Device
The 241941005 Frigidaire Refrigerator Start Device is an electromechanical⢠component that provides the brief additional torque needed to bring a singleâphase compressor up to synchronous speed by momentarily âdiverting current through âtheâ start winding. â¤In practical terms⤠this device behaves either âŁas a solidâstate PTC or an âelectromechanical relay depending on design, but nonetheless of construction it must match the compressor’s electrical characteristicsâ (nominal⢠115-120 VAC systems in North America), terminal arrangementand physical mounting. Compatibility is resolute by electrical rating, connector styleand the compressor’s start/run winding configuration rather than by ârefrigerator cabinet appearance; twoâ compressors that â¤look similar can require different relays if the terminal layout or inrush characteristics differ.
- Electrical â˘rating: match nominal âline voltageâ and âexpected inrush current.
- Terminal layout: start, run (andâ sometimes common/line) must align with the harness.
- Connector/harness â˘compatibility: plug style and wire lengths must permit secure connections.
- mounting footprint: clip or â¤bracket type must seat onâ the compressor without⢠strain.
- Compressor type: verify singleâphase start relay vs. start capacitor requirements.
Replacement procedure focuses on verification and⣠safe,precise installation: de-energize the appliance and unplug it before accessing the compressor. Remove the rear access panel or insulation, note and label âŁthe existing wire⤠positions, then release âthe relay from its compressor mounting (many are springâclip or snapâfit on the compressor flange). Install the new device by aligning terminals and seating the clip without forcing wires; confirm tight terminal fit andâ apply any specified environmental sealâ or protective boot.After reassembly, perform a functional check by powering the unit and observing compressor start behavior and⤠current draw withâ a clamp meter; abnormal hum, repeated⣠attempts to startor excessive current indicateâ a mismatch or a failing compressor thatâ cannot be solved by replacing the start device alone.

Q&A
What is the 241941005 frigidaire Refrigerator Start Device and whatâ does it do?
The âŁ241941005 start device is the compressor start component used on many Frigidaire âŁrefrigerators. It provides the temporary extra torque âor switching needed to get the compressor motor up to âspeed on startup (functionsâ asâ a start relay/PTC or start device assembly). Without a working start⣠device the compressor may hum but fail â¤to âstart,so the fridge will not cool properly.
What⤠are the common symptoms âof a failing 241941005 start⢠device?
Commonâ signs⤠include: compressor humming but not running, frequent â˘clicking or cycling, refrigerator not âŁcooling, compressor runs intermittently, tripped breakeror burnt/melted plastic around the start device. If the compressor overheats and then⢠starts after âcooling, âthe start device⣠may be marginal.
