5304497345 Frigidaire Refrigerator Temperature Control is the temperature regulation assembly used in Frigidaire refrigeration appliances; it is indeed the user-accessible ā¢control/thermostatic ādeviceā¤ that senses cabinet conditions and controls electrical outputs to maintain a selected interior temperature. Dependingā on the model, the assembly can be an electromechanical thermostat or an electronic ā¢control moduleand it typically includes ā¢the temperature setpoint interface, sensing elementand switching contacts or logic that make and break power to downstream loads.
Inside the appliance the ātemperature control serves asā the primary decision point for cooling cycles, interacting directly with the compressor start circuit, evaporator āfan, interior fans or damper actuators and, in some designs, defrost sequencing or a mainā control board. Its sensing element monitors air or evaporator temperature and, when āthe measuredā value crosses the āsetpoint, the control closes or āopens electrical paths to start or stop the compressor and related fans.Proper operation requires correct electrical connections, intact āsensing feedbackand unobstructed air flow between āthe evaporator and theā£ monitored compartment.
In this article you āwill find āa practical technical overview of theā¢ 5304497345 control: ā£how it āfunctions, typical mountingā andā wiring arrangements, compatible applianceā locations and modelā£ considerations, common failure modes and symptoms (for example ācontinuous compressorā¤ operation, short cyclingor loss of cooling), step-by-step troubleshooting techniques (visual inspection, continuity and voltage checks, verifying airflow and evaporator condition)and guidance on replacement considerations such as matching part numbers, connector pinoutsand safe handling procedures. The focus is ā¤on providing technicians, engineersand experienced applianceā¤ owners with ā£the diagnostic context ā¢and replacement criteria needed to restore reliable temperature control without vendor marketing languageā¤ or unsupported claims.

Function and Role of ā¢the Temperature Control Module in Refrigerator Cooling and Setpoint Regulation
The 5304497345 Frigidaire Refrigerator Temperature Control is the electronic ā£decision-making module that monitors evaporator temperature input(s) and drives the compressor, evaporator fan and defrost control to maintain the user setpoint.It reads one orā¢ more thermistor signals, applies ā¤a control strategy with a defined on/off differential and built-in timing ā¤logicandā energizes the compressor relay or solid-state switching element accordingly.ā The module enforces safety timing such as short-cycle protection to prevent rapid compressor restarts ā¤and uses a temperatureā differential (typically a few degreesā Fahrenheit) to avoid continuous cycling whileā keeping the ācabinet temperature near the selected setpoint; for example, a 37 Ā°F setpoint will typically be maintained within an approximate Ā±2-4 ā¢Ā°F band depending onā door openings and load conditions.
Behaviour and compatibility are practical concerns for technicians: the control’s outputsā¤ must match the refrigerator’sā¢ harness, connector pinoutā£ and mains switching capability, ā£and replacement ā£units likeā£ part number ā5304497345 should be verified against the model’s service parts list before installation. When diagnosing, separate sensor faults from control faults by verifying thermistor resistance vs. temperature and āconfirming the control’s relay/switch output under a forced-call condition (lowering setpoint toā request cooling).ā Typical symptoms indicating control issues include continuous compressorā run without temperature recovery, no compressor activity while fans operateand erratic cycling or failure āto follow setpoint; these observations guide weather toā replace āthe control module,ā repair wiring/connectors, ā¤or test the ācompressor and ā¤start components.
- common features: thermistor inputs, compressor relay output, evaporator fan control, defrost control and timing logic.
- Common symptoms of module or interface failure: no compressor start, continuous run, inconsistent temperatureor control display errors.
- Practical verification steps: check connector pinout,measure sensor resistance,observe relay switching under a āforced-call,and confirm short-cycle delay ābehavior.

How the 5304497345 Frigidaire Refrigerator Temperature Controlā¢ Works Inside the Appliance: electrical, Thermistor and Relay Interactions
The 5304497345 Frigidaire Refrigerator temperature Controlā is the electromechanical/electronic module that interprets temperatureā feedback and switches refrigeration loads accordingly. Inside the appliance, a temperature-sensing elementā (typically an NTC thermistor) forms part of ā¢a voltage-divider or ADC input to the control electronics; its resistance falls as the evaporator or compartment temperature rises, producing a measurable āvoltage change the controller uses to determine whether to call for cooling. When the controllerā¤ determines the compartment exceeds the setpoint, it energizes an output āthat drives the compressor circuit – usually by actuatingā£ a dedicated relay orā¢ a solid-state switching ā¤device – and may also sequence the evaporator fan or defrost heater based on timed or temperature-basedā¤ logic. Techniciansā£ should expect to see low-voltage controlā¢ logic on the board side and switched line voltage on the compressor/fan side, with the 5304497345 assembly acting as the ā£intermediary that ensures those domains interact safely and predictably across compatible Frigidaire harnesses.
In practical ā¤terms the electrical interactions are āstraightforward to verify: measure the āthermistor resistance āacross temperature change to confirm a monotonic NTC response,ā and check for continuity or line voltage at the relay output when the control callsā¤ for cooling.The relayā£ contact closesā to supply mains power to āthe compressor/start relay or fan, while the control electronics supply onyl the coil/drive voltage ā¢or logic signal; failures manifest as no compressor runā despite correct thermistor readingsor a shorted relay that ākeeps the compressor energized continuously.Compatibility considerations include connector type, ā£mounting orientation, ā¤and whether āthe control uses passive switch contacts orā active transistorized outputs -ā replacing the assembly requires matching the electrical interface and expected control signals rather than merely matching the external appearance.
- Thermistor behavior: NTCā¤ resistance decreases with increasing temperature; measuredā with an ā£ohmmeter for diagnostics.
- Relay/output: switches line voltage to compressorā¤ and fans; audible click during actuation is normal.
- Controlā interface: low-voltage logic on board side, mains on load side – ensure correct harness pinout when replacing.

Common Failure Symptoms and Diagnostic Indicators for the 5304497345 Temperature control: Temperature Drift, Intermittent Compressor/Fan āOperationand Electrical Faults
The 5304497345 Frigidaire Refrigerator Temperature Controlā regulates āthe refrigeratorS cooling cycle byā£ sensing cabinet temperature and commanding the compressor, evaporator āfanand associated relays.In manny serviceable installations this control takes input from a temperature sensor ā(thermistor) or a mechanical thermostat and translates that ā£into an on/off call for the compressor and ā¢fan; on electronic boards it also provides diagnostic feedback and timing logic. When the control degrades it no longer maintainsā¤ a stable ā¢setpoint,which leads to temperature drift,unpredictable compressor or fan operation,orā intermittent electrical faults that can appear as burned terminals,relay chatter,or blown fuses. Understanding whether the control itself is āat faultā requires separating sensor, relay,ā¤ andā£ wiring failures from refrigerant- or airflow-related problems, since similar symptoms canā£ arise from unrelated system issues.
Diagnostic indicators to target during troubleshooting include abnormal cycling patterns logged over ā¤several hours, loss of continuity orā¢ improper resistance values at the sensor/thermostat terminals, absence of line voltage to āthe compressor relayā during a cooling demand, visible heat damage at connectorsand audibleā relay clicking without corresponding compressor operation. Practical checks: record ā¢cabinetā temperature toā confirm drift, measure the sensor resistance āand compare to the expected curve for that ā¢sensor type (many thermistors approximate a predictable resistance at 25Ā°C), use a multimeter to verify ~120 VAC is present at the relay output āwhen the controlā calls for coolingandā inspect harnesses for corrosion or loose pins.If tests isolate ā£the control board (no sensor or wiring faults and correct supply āvoltage but improper āoutputs), replacing the 5304497345 control can resolve intermittent cycling and electrical anomalies; technicians should alsoā£ confirm ācompatibility with the specific Frigidaire modelā¤ and service manual pinouts before installation.
- Temperature ā£drift: steady riseā or fall of cabinet temperature ā¢despite normal ācompressor runtime.
- Short cycling: compressorā runs for seconds āto minutes repeatedly; suggests relay āor control timing fault.
- Intermittent fan: fan stops while compressor ā¤runs, indicating a control output or fanā¢ motor issue.
- Audible relay chatter āor ā£clicking without compressor engagement.
- Visible electrical damage: burned terminals, melted insulationorā blown fuses onā the control harness.

|---|---|
| Continuity/Resistance Check | Verify sensor/thermostat resistance against expected values; check continuity across relay contacts during a cooling ādemand. |
| Voltage Output | Confirm āline ā£voltage (~120 VAC) is present atā¢ the compressor relay output when the control is calling for ā¢cooling. |
