241941005 Frigidaire Refrigerator Start Device is a compressor start aid used on Frigidaire refrigeration units; it is a start relay/start‑assist module type component that helps engage the compressor motor at initial power‑up. As a dedicated start device it is typically installed at the compressor terminal or in the appliance’s control compartment adn is designed to provide a timed connection to the compressor’s start winding or to alter starting current so the hermetic compressor can develop sufficient torque to begin normal operation.
Inside the appliance the start device interfaces directly with the compressor motor circuit and works in concert with the overload protector, the run winding (and any run capacitor where applicable), the main power supplyand the thermostat or electronic control board that calls for cooling. Its correct operation affects inrush current,start duration and the mechanical stress on the compressor; a faulty start device can produce no‑start conditions,repeated start attempts,excessive current draw,or thermal trips,and therefore has a direct impact on the refrigeration cycle and overall reliability.
In this article readers will find a technical clarification of how the 241941005 start device functions, guidance on compatibility and selection for specific compressor models, common failure symptoms to watch for, practical troubleshooting steps and diagnostic checks a technician can perform, and considerations for safe removal and replacement (including matching electrical characteristics and mounting/wiring requirements).The focus is on providing the information needed for accurate diagnosis and correct component replacement while observing standard electrical safety practices.

Functional Role and Electrical Specifications of the Refrigerator Start Device
The 241941005 Frigidaire Refrigerator Start Device provides the short-duration assist required to bring a hermetic compressor up to running speed by temporarily engaging the compressorS start winding. In common designs this module is implemented as a PTC thermistor or electromechanical relay that presents low impedance to the start winding during initial energization and then removes or limits that path as the motor approaches synchronous speed; electronic variants detect back-EMF and open the start circuit without a timed delay. Typical observable behaviors from a defective start device include a steady humming compressor, failure to achieve cut-inor frequent trips of the external overload protector caused by the start winding overheating when the device fails to disengage.
- Primary function: provide momentary start torque by connecting the start winding, then disconnect or limit it once the compressor runs.
- Failure symptoms: humming, no start, intermitted startsor rapid overload trips.
- Compatibility considerations: match terminal arrangement and voltage rating to the original harness; physical plug-in form factor matters for fit.
- Diagnostic clues: mechanical relays show open/start continuity differences when energized; PTC devices show low cold resistance that rises under heat.
| Item | Description |
|---|---|
| Operating voltage | Nominal 115-125 VAC single-phase (verify nameplate on unit) |
| Functional type | PTC thermistor,electromechanical relay,or solid-state back-EMF sensing circuit |
| Current capacity | Designed to tolerate compressor locked-rotor currents typical of household hermetic compressors (single- to low double-digit amperes) |
| Connection | Plug-in terminals matching Frigidaire harnesses; confirm terminal layout before replacement |
Electrical replacement and troubleshooting require verifying supply voltage,terminal mapping,and measuring continuity/behavior under test conditions rather than relying on visual inspection alone.For example, a simple bench check for a relay-type start device is to apply controlled mains voltage with proper load simulation to observe contact closure timing, while a PTC device is typically tested by measuring cold resistance and confirming that resistance rises with applied voltage/heat; always isolate the compressor before substituting parts. Before installing a replacement, verify the part number and terminal arrangement against the appliance’s service data or the original module to ensure that the 241941005 form, functionand ratings match the compressor and control wiring.
How the 241941005 Frigidaire Refrigerator Start Device Operates in the Compressor Motor Circuit
The 241941005 Frigidaire Refrigerator Start Device is a motor-start component that provides the brief high-torque current needed to bring the compressor up to operating speed before the run winding carries the load. In practical terms this device either momentarily connects the compressor’s start winding or presents a low-resistance path that collapses as the motor accelerates; designs are commonly realized as a PTC thermistor (solid-state) or an electromechanical start relay. The start device works in concert with the compressor’s overload protector and run capacitor (if present), and is typically mounted at the compressor terminal block or inside a refrigerator relay/relay socket assembly so that it commutes the start circuit only during motor startup.
Behavior and compatibility depend on construction: a PTC-based 241941005 will gradually increase resistance as it heats, passively timing the start interval, while a relay-type unit will click open once the motor reaches speed. For replacement or troubleshooting, match terminal layout, mounting styleand rated application (household mains such as 115-120 V in North America) rather than only matching part number; mismatched characteristics can lead to hard starts or nuisance failures. Common diagnostic cues include a humming compressor that fails to spin up, intermittent startsor visible arcing at the relay terminals. Technicians typically check for continuity between start and run terminals,observe relay actuation on startup,or substitute a known-good start device to confirm the fault before replacing the compressor itself.
- Primary function: temporarily engage the start winding to generate initial torque
- Common failure symptoms: compressor hums but does not start, delayed startsor reduced cooling performance
- Types: PTC (thermistor) or electromechanical relay-each has different test methods
- Replacement guidance: match terminal configuration, mountingand application voltage

Common Failure Symptoms and Diagnostic Indicators for Start Device Malfunctions
241941005 Frigidaire Refrigerator Start Device is the auxiliary component that provides the compressor with the brief surge of torque required to overcome static friction and refrigeration load at start-up. In many Frigidaire systems this part functions as a relay or solid-state PTC-style starter that momentarily routes current to the compressor’s start winding or modifies the winding impedance until the motor reaches running speed,then drops out so only the run winding remains energized. The start device works in tandem with the compressor’s thermal overload protector; improper matching of the start device to the compressor electrical characteristics or connector layout can produce repeated hard starts, overheatingor premature overload trips, so confirm voltage ratings and compressor model compatibility when replacing the unit.
Common failure symptoms and diagnostic indicators are electrical and mechanical: the compressor may hum without spinning, exhibit rapid on/off cycling, or not start until multiple attemptsand the refrigerator compartment temperature will rise. Practical checks include observing audible behavior at start (clicking relays, sustained hum), inspecting the device for discoloration or melted terminalsand measuring circuit continuity and relative resistance of the start path compared to manufacturer references.typical observable symptoms include:
- Compressor hums but does not start (no crank or rotation).
- Repeated attempts to start with audible clicking or relay chatter.
- Frequent tripping of the household breaker or overload during start-up.
- Intermittent starts that work after the unit cools down or after multiple tries.
- Visible overheating, burning smellor damaged terminals at the start device.

Replacement Considerations, Model Compatibilityand Installation Procedures for the 241941005 Start Device
The 241941005 Frigidaire Refrigerator Start Device is a motor-start assist component designed to momentarily energize the compressor’s start winding so the hermetic single‑phase compressor can overcome static friction and begin normal operation. In service, this part behaves like a momentary relay/PTC device: it provides a brief high‑torque current path to the start coil and then drops out to allow the run winding to carry the motor. typical failure modes include complete failure to engage (compressor hums but does not start), intermittent startsor thermal degradation visible on the housing; these symptoms should be confirmed by measuring compressor winding continuity and by checking inrush current against the manufacturer’s service specification. Verify compatibility by matching the part number, the terminal arrangement (spade orientation and count), and the device’s current/temperature characteristics to the refrigerator’s service manual and the compressor model, because physical mounting and electrical ratings vary between families of compressors even within the same brand.
Follow safe, methodical procedures for replacement: disconnect mains power, access the compressor compartment, and identify the start device attachment (clip‑on or bolted to the compressor). remove the old device, inspect terminals and insulation, and transfer or replace any mounting hardware and wire ferrules to ensure low resistance connections. After installing the new start device, restore power briefly while monitoring starting behavior and motor current; a properly functioning replacement will allow the compressor to start within a few seconds and will not show sustained excessive current. If the compressor still fails to start, check the overload protector and measure winding resistances again-replacement of the start device will not correct an internally locked or mechanically seized compressor.
- basic replacement steps: Disconnect mains power → access compressor → remove old start device → install new device with correct terminal orientation → secure mounting and insulation → restore power and observe start/current.
