5304497345 Frigidaire Refrigerator Temperature Control is a temperature-regulating assembly used in Frigidaire refrigerators; it functions as the control element that senses cabinet temperature and opens or closes electrical circuits to maintain the setpoint. The part is commonly identified as a temperature control (thermostat or electronic control module) and may incorporate sensing elements, a user interface or knob mountingand switching contacts or low-voltage interface circuitry depending on the model.
Inside the appliance, this temperature control monitors the evaporator or cabinet temperature via an internal sensor or thermistor input and issues switching commands to the refrigeration system. It directly or indirectly controls components such as the compressor (through a relay or start device), the evaporator fan, and, on some models, elements of the defrost sequence. The control thus interfaces with the main control board or relay assembly, the temperature sensor, compressor starter hardwareand fan motors; proper operation is essential for stable temperature regulation, efficient cyclingand preventing excessive frost or food spoilage.
This article explains how the 5304497345 temperature control functions, where it is typically located and fitted in refrigerator modelsand how to verify compatibility with specific appliance serial/model numbers. It also reviews common failure symptoms (for example continuous run, no runor improper temperature), practical troubleshooting checks (sensor resistance, continuity and voltage verification, and wiring/harness inspection)and considerations for replacement and calibration to restore correct operation. Safety precautions and recommended tests for technicians and experienced appliance owners are included to support accurate diagnosis and repair decisions.

Function and Role of the Temperature Control in the Refrigeration Cycle
The 5304497345 Frigidaire Refrigerator Temperature Control serves as the sensing and switching element that governs compressor and evaporator-fan operation, closing the loop between measured cabinet/coil temperature and the refrigerator’s power relays or control board. It interprets input from a thermistor or thermostat sensor and issues a binary or modulated command to the compressor starter; when the sensed temperature rises above the setpoint the control energizes the compressor and fansand when the temperature falls below the setpoint it de-energizes them.This device thus determines cycle duration, average cabinet temperatureand how the system interacts with defrost termination or anti-short-cycle timers-verify connector pinout, sensor typeand electrical ratings when replacing the control to ensure proper compatibility with the appliance’s starter relay and defrost circuits.
- Sensing: reads evaporator or compartment temperature via thermistor or mechanical sensor.
- Compressor control: closes/open contacts or signals the board to run the compressor based on setpoint.
- Fan/defrost coordination: enables evaporator fan during cooling and cooperates with defrost termination sensors.
- Protection and behavior: implements hysteresis/deadband and anti-short-cycle timing to protect the compressor and control cycling duty.
The control’s switching characteristics-specified deadband, thermal time constantand any built-in anti-short-cycle delay-determine how frequently the compressor runs and therefore affect energy use, noiseand frost accumulation. Typical failure modes include continuous running with no temperature recovery (open sensor or stuck contacts), rapid short-cycling (wrong differential or failed relay)or failure to terminate defrost; technicians commonly diagnose these issues by measuring sensor resistance versus temperature, checking continuity across switch contactsand observing relay actuation. When replacing the control, match sensor type and electrical specifications precisely because substituting a control with a different differential or connector arrangement can produce persistent temperature offsets or excessive cycling even if the replacement physically fits.
How the 5304497345 Frigidaire Refrigerator Temperature Control Interfaces with Sensors, Thermostatand Compressor
5304497345 Frigidaire Refrigerator Temperature Control serves as the electronic gateway between the refrigerator’s temperature sensors and the mechanical refrigeration components. It monitors one or more thermistor inputs, compares measured temperatures to the user setpoint and internal hysteresis, and then drives outputs such as the compressor relay, evaporator fanand air-damper actuator. In practice this control module provides timed and conditional switching (minimum off-time, anti-short-cycle protectionand coordinated fan/compressor sequencing) so the compressor is started and stopped in a safe, efficient pattern. This part is intended for Frigidaire models that specify the 5304497345 number; technicians should confirm connector pinout and mounting compatibility against the service manual or the existing harness before replacement.
The control’s behavior is diagnostic-friendly: a persistent call for cooling with no compressor run usually points to a failed relay/output or missing supply voltage, whereas continuous compressor operation with stable temperatures often indicates a sensor out of range or incorrect resistance reading. Typical checks include measuring thermistor resistance at ambient temperature, verifying the presence of control voltage to the compressor relay coiland observing fan/damper responses during a cooling cycle. Practical interface items to inspect or monitor during troubleshooting include:
- thermistor inputs: verify expected resistance trends as temperature changes.
- Compressor relay output: confirm switching voltage and minimum off-time enforcement.
- Evaporator fan/damper control: ensure coordinated airflow control during cycles and defrost.
| Item | Description |
|---|---|
| Thermistor input | Analog resistance signal that the control interprets to determine temperature and call for cooling. |
| Compressor relay output | Switched power controlled by the module; includes anti-short-cycle timing to protect the compressor. |
| Fan/damper control | Outputs that sequence airflow and compartment isolation to maintain even temperatures and support defrost. |
common Failure Symptoms and diagnostic Indicators: Temperature Drift, Compressor Cyclingand Electrical Faults
The 5304497345 Frigidaire Refrigerator Temperature Control is the control module that interprets thermistor input and governs the compressor, evaporator fanand defrost sequencing to maintain setpoint temperature. In normal operation the control switches outputs according to temperature thresholds and timing logic; failures in the control or its sensor manifest as steady temperature drift, unexpected compressor starts and stopsor loss of cooling despite a running compressor.Technicians should consider compatibility with specific Frigidaire chassis and model-year variants when diagnosing or replacing this part, because timing algorithms and connector pinouts can differ between control assemblies. Use a multimeter to verify sensor resistance changes with temperature and a clamp meter to observe compressor current during suspected short-cycling to separate control faults from load or refrigerant issues.
- Steady upward or downward temperature drift inside the cabinet
- Frequent compressor short-cycling (on/off every few minutes)
- Long compressor run times without reaching setpoint
- Intermittent clicking,blown fuses,or tripped breakers linked to control outputs
- Error codes or fault LEDs (on models that report diagnostics)
Diagnostic focus should be on isolating whether the symptom originates from the thermistor,wiring/connectors,external loads (condenser cleanliness,door gasket leakage),or the control board itself. For example,if the thermistor resistance responds predictably when warmed or cooled but the control does not energize the compressor output,the control relay or driver stage is the likely failure; conversely,if the thermistor is open or shows no change,replace or retest the sensor and harness first. Inspect solder joints and plug terminals for heat damage or corrosion and confirm line and switched voltages at the control terminals under load; persistent irregularities at the outputs with correct input signals indicate the control assembly requires replacement with the correct, compatible part number.
| Item | Description |
|---|---|
| Temperature drift | Check thermistor response, door seals, evaporator airflow; verify control setpoint and sensor wiring continuity. |
| Compressor cycling | Measure compressor current and run/stop intervals; test start relay/capacitor; observe control output timing for premature cutoff. |
| Electrical faults | Inspect connectors and PCB for burns, test relay coil continuityand confirm mains and switched voltages at control terminals. |
Replacement Considerations and Installation: Model Compatibility,Parts Verification,and Step‑by‑Step Mounting procedure
The 5304497345 Frigidaire Refrigerator Temperature Control is the user-set thermostat/electronic control interface that governs compressor cycling,evaporator fan operation,and temperature-related defrost intervals. Functionally, the part either provides a switching contact that opens and closes based on a sensor or provides setpoint and signal conditioning to the main control board; therefore verifying the physical connector count, mounting orientationand sensor/probe retention are critical for compatibility. technicians should compare the replacement part’s harness pinout, bracket geometryand probe insertion depth against the original assembly because mismatched probe placement or a reversed connector can produce incorrect temperature readings or prevent compressor startup even when the replacement part shares the same part number series.
Installation requires mechanical alignment, correct electrical matingand post-install functional verification. Before reinstalling panels, confirm continuity across thermostat contacts at ambient and after cooling the probe (or simulate with a calibrated temperature source), ensure the probe grommet seals the evaporator housing to maintain thermal coupling, and verify the control communicates properly with the main board if it uses signal lines rather than simple switch contacts. After power is restored, allow at least 12-24 hours for the system to stabilize and observe compressor run/stop cycles, evaporator fan operationand temperature trends; if the refrigerator exhibits rapid short-cycling, no compressor runor persistent fault codes, re-check harness pinout, ground continuityand probe placement before replacing additional components.
- Pre-install: disconnect mains,photograph wiring,compare part shape and connector pins.
- Bench test for continuity/resistance across relevant terminals at known temperatures.
- Mount using original bracket points and ensure probe/grommet seating for correct thermal contact.
- Power up, monitor compressor/fan behaviorand log temperatures over 12-24 hours.
