Functional role and Electrical Integration of the Refrigerator Temperature Control Module
The 5304497345 Frigidaire Refrigerator Temperature Control â˘is an electronic control module that monitors evaporator temperature and actuates the refrigerator’s cooling and defrost circuits. It accepts a âlow-voltage input from â˘an evaporator thermistor or temperature sensor and uses that information to switch mains-rated âŁoutputs (typically through a relay or solid-state switch) for the compressor, evaporator fanand âdefrost heater. In practice this module enforces setpoint and hysteresis logic to limit⣠compressor short-cycling and to initiate defrost cycles on a timed⤠or⣠temperature-based âschedule; compatibility with a specific Frigidaire model is resolute by connector pinout, supply â¤voltageand signal conventions, so technicians should⢠confirm harness and control board interconnections before replacement.
Electrically, the unitâ normally⢠has a line and neutral feed⣠for powering its switching outputs and⤠internal electronics, a sensor input for the thermistorand one or more switched outputs⢠for compressor and heater circuits. Typicalâ troubleshooting steps includeâ verifying mains presence at the module, checking for a switching voltage on the compressor lead when the unit calls for cooling,â and measuring sensor resistance at ambient temperature â¤to confirm the thermistor circuit is functional. The âcontrol also monitors for fault conditions such as open/short âŁsensor or stuck relay and will â¤alter behaviour (lock out compressor, âextend defrost) when those conditions are detected; consult the model wiring diagram âto map the module’s pins to harness wires and to confirm expected voltage levels before replacing the part.
- Power input: line/neutral for switching outputs
- Sensor input: thermistor/temperature sensor signal
- Switched outputs: compressor,evaporator fan,defrostâ heater
- Possible communication or âstatus output toâ mainâ control board on some models
| Item | Description |
|---|---|
| Supply voltage | Mains âline and neutral (moduleâ switches mains to compressor/heater) |
| Sensor âtype | thermistor input (variable resistance vs. temperature) |
| Outputs | Relay â¤or solid-state outputs for compressor, fanand defrost heater |
How the 5304497345â Frigidaire Refrigerator Temperature Control Interfaces⤠with Sensors, Relaysand the Compressor
Theâ 5304497345 Frigidaire Refrigerator Temperature Control reads temperature from one or more NTCâ thermistors or equivalent sensors, converts that resistance into a voltage/logic input,⢠and compares âŁit to the user setpoint and builtâin hysteresis.⢠When â¤the measured temperature exceeds the setpoint, the control closes its mainsârated relay orâ issuesâ a control signal to a compressor â˘contactorand it usually provides a âŁseperate output for the evaporator fan. Internally⢠the module is designed to handle the high inrush âcurrent associated with compressorâ starts either through heavy â¤duty relay contacts or by interfacing with an external start relay/overload assembly, so replacement compatibility requires matching voltage,⤠contactâ ratingsand terminal assignments rather⣠than just âphysical fit.
- Sensor input:â NTC⤠thermistor âor similar lowâvoltage⤠temperature input
- Control outputs: mains relay/contact for compressor,â fan output,â possible defrost/aux outputs
- practical tests: measure⤠sensor resistance vs. expected curve, check for mains at compressor âwhen cooling is called
| Item | Description |
|---|---|
| Sensor input | Lowâvoltage thermistor â¤resistance translated to temperature by the control’sâ analog/digital circuitry |
| Relay output | Mainsârated contacts or control signal sized for compressor start current or contactor coil |
| Compressor interface | Provides mains power to compressor via internal contacts or external start relay; must match compressorâ voltage and inrush requirements |
In practical diagnostics, technicians confirm the sensor curve with a multimeter at known temperatures and then observe whether the control energizes the compressor output when the sensor⣠shows a warm condition. If theâ sensor and control supply voltage are correct but the compressor does not âstart, the likely fault is in the relay/contacts or their drive âcircuit; âchecking for continuity across the output contacts under load and measuring line voltage at theâ compressor terminals during a call for cooling isolates the failure. For repairs or replacements, âensure the replacement control⢠matches â˘theâ original’s electrical rating, wiring diagramand any required safety â¤interlocks to avoid improper âoperation or premature component âfailure.
Diagnostic âIndicators and âŁCommon Failure âŁSymptoms: Temperature Drift, continuous⢠Running,⤠and intermittent Cooling
The â˘5304497345 Frigidaire Refrigerator Temperature⢠Control is the component that translates a⤠user setpoint into a âphysical call for compressor and evaporator fan operation through an internal sensing element and switch.In practical terms itâ closes a⣠contact when the internal temperature rises above the âsetpoint and opens it when the setpoint is reached; failure modes include loss of calibration (temperature⤠drift), mechanical contact wearor degraded âŁsensor response. âCompatibility for replacement requires matching the control’s mounting footprint, connector pinoutand whether theâ unit is a mechanical bimetal thermostat or an electronic controller – mixing types can produce improperâ cycling or incorrect temperature regulation.
Diagnosing drift, continuous runningorâ intermittent âcooling requires both observation and electrical checks: verify compressor run time versus expected duty cycle, measure continuity across the control while changing settingsand confirm stable supply voltage âat the harness. Temperature drift â˘commonly manifests as a⤠slowly changing cabinet temperature with apparently normal compressor cycles, continuous running usually indicates a stuck or welded contact or a persistent sensor calland âŁintermittent cooling often traces to marginal contacts, corrosion in âŁthe harness, âor intermittent internal failure. Practicalâ field checks include wiggle tests on connectors while monitoring continuity, logging run/idle durations to compare against expected behaviorand replacing the âcontrol with a known-good unit when electrical measurements âare inconclusive.
- Temperature drift: Gradual deviation from setpoint⢠– likely sensor calibration shift or â˘aged sensing element.
- Continuous running: Compressor runs non-stop – likely stuck contact, failed open/closed thermostator incorrect⣠control type.
- Intermittent cooling: Sporadic compressor operation – possible loose connector, corroded terminals,⢠or failing internal contacts.
| Item | Description |
|---|---|
| Continuityâ test | Expect open/closed contact change when rotating âsetpoint; use multimeter to verify switching action. |
| Voltage check | Confirm âcorrect supply voltage at control harness during both idle and call-for-coolâ states. |
Replacement considerations and⢠Step-by-Step Installation Procedures for the Control assembly
The 5304497345 â¤Frigidaire Refrigerator Temperature Control is an electromechanical/electronic assembly that regulates compressor and evaporator-fan runtime by switching line voltage based on a temperature setpoint and feedback from the internal sensor. In practiceâ this control⤠behaves as the ârefrigerator’s central thermostat: it closesâ and opens the compressor circuit to maintain the cabinet temperature and can also provide inputs for defrost timing on some models.Before replacement,confirm electrical connector type,mounting footprint,and sensor placement – identical nominal voltageâ and harness pinout are required for safe operation,and a âcontrol with the correct sensor location is necessary to avoid offset temperature readings (such âas,a control designed for top-mounted sensors will read warmer if installed in a bottom-sensor cabinet).
- safety first: disconnect mains⤠power and verify âwith a multimeter beforeâ touching wiring.
- Document or photograph wireâ positions and harness orientation; mark connectors⣠to avoid interchange errors.
- Remove trim and⣠access the control housing; retain gasket or insulating materials to preserve airflow paths.
- Unscrew the control, unplug â˘the old unitand inspect the harnessâ for heat damage or corrosion-replace harness if connectors are compromised.
- Install the replacement 5304497345 unit,seating sensors and grommets in the same locations;â torque mounting screws evenly to avoid housing deformation.
- Restore power and âperform a continuity and actuation check (use a temperature chamber or warm/cool the sensor to⣠observe relayâ switching).
- Monitorâ cabinet temperatures over 24 hours and adjust the setpoint if measured offsets appear due to sensor repositioning.
After mechanical installation and initial electrical checks, verify system-level behavior: confirm âŁcompressor run/stop cycles, evaporator fan operation during compressor âŁruntimeand proper defrost initiation ifâ applicable.â Use a clamp meter to verify inrush and running current against manufacturer nominal âŁvalues to detect increased load from compressor or â¤shorted windings that⢠might have coincided⤠with control failure. If the new control exhibits rapid short-cycling, re-check sensor mounting and cabinet airflow obstructions before âreplacing other components; conversely, âŁa control that failsâ to energize the compressor âwith properâ setpoint and correct wiring indicates âa defective relay or mismatched control type and should be replaced with a verified equivalent.

Q&A
What is Frigidaire âpart âŁ5304497345 and what does the temperature control do?
part 5304497345 is the â¤temperature control/thermostat assembly used on some Frigidaire refrigerators. Its job is⤠to monitor cabinet temperature (directly or via âa sensor) and switch the compressor, evaporator fan,â and defrost components on and off to maintain the set temperature. Depending onâ the model it can be a â˘mechanical⢠thermostat or an electronic control module that communicates with the main control board.
Whatâ symptoms indicate the 5304497345 temperature control might be failing?
Common signs include: refrigerator â˘running continuously, compressor not⤠starting, fridge too warm or too âcold despite changing the dial, frequent on/off cycling (short-cycling)or inability to initiate a defrost cycle if the control⢠handles that function. Also watch for no change in compressor or fan behavior when you⢠move the temperature control setting.
How do I test the 5304497345 to confirm it’s defective?
First unplug the refrigerator.â For a mechanical⢠type, remove the control and check continuity âwith⢠a multimeter while moving the temperature knob-continuity should open/close as â¤the control is adjusted. For electronic controls, visually inspect connectors âand wiring, then with power restored and caution,â verify the control is putting voltage to the compressor relay/fan when the setpoint calls for cooling. Ifâ the control uses a thermistor or sensor, measureâ its resistance and compare to the service manual/spec sheet (thermistor âvalues vary by model). If you’re unsure how to â¤perform live voltage checks, have a qualified technician test it-live tests carry shock risk.
Can I replace the 5304497345 myself and what are the basic steps?
Yes, a competent diyer can replace it, butâ always unplugâ the appliance first. â¤Basic steps: locate the control (usually in the refrigerator âŁcontrol housing or behind the control panel), remove trim/panel screws, note and photograph connector locations, disconnect wiringâ harnesses, remove the⣠old control, install the new part and reconnect âharnesses exactly, reassemble panels, plug⤠in and verify operation by setting temperature and observing compressor/fan operation.
