5304497345 Frigidaire Refrigerator Temperature Control âis a temperature control⢠assembly used in Frigidaire ârefrigeration appliances to regulate internal cabinet temperature. Theâ component functions as the user-adjustable setpoint and control interface that governs when the cooling system runs; depending on the model it can be implemented as a mechanical thermostat, âan electronic âŁcontrol module, â˘or a hybrid that uses a small â¤thermistorâ or sensing⤠element toâ measure temperature.As a factory-designated replacement part⣠number, it is specific to certain Frigidaireâ models and is intended âŁto match the electrical and mechanical âinterfaces of those refrigerators.
Inside â˘the appliance the temperature control monitors cabinet â˘temperature and⢠issues on/off or modulated commands to⤠the refrigeration subsystem, typically interacting with the âŁcompressor relay, evaporator fan motorand, in electronically managed systems, the main control board and defrost timer/heater. The control â˘reads temperature via an integrated⢠sensor or external probe and âŁcompletes circuits or transmits signals that prevent short-cycling, coordinate defrost cyclesand maintain the selected setpoint.Proper operation of this part⤠is therefore central to coolingâ performance, energy usageand⤠component⢠longevity becuaseâ incorrect control behaviourâ can â˘cause poor temperature regulation, excessive compressor run-timeor unnecessary defrost âevents.

Functionâ and Role of the Refrigerator Temperature control Module â¤in the Cooling System
The 5304497345 Frigidaire Refrigerator Temperature Controlâ is an electronic control module âthat monitors temperature via aâ cabinet or evaporator sensor and issues control signals to the⣠compressor, evaporator fanand defrost system. Theâ module interprets the sensorS resistanceâ (thermistor) and applies a control strategy-typically on/off switching with defined hysteresis or timedâ duty cycles-to maintain setpoint temperatures while preventingâ short-cycling. In practice this means the controlâ closes a âŁcompressor âŁrelayâ or drives⣠a âsolidâstateâ switch when the sensed temperature rises above the cooling thresholdand âŁopens the circuit once the temperature falls below the lower⢠threshold;â it â¤also coordinates with defrostâ sequencing⣠and damper/fan logic so â˘thatâ cooling and air circulation occur in â˘the correct order for stable cabinet temperatures.
Compatibility and troubleshooting require checking â¤mechanical mounting, connector pinout, supply⢠voltageand sensor⣠characteristics against âthe refrigerator’s âŁservice documentation. Common fieldâ symptoms that point to a failing temperature control include continuous compressor operation, failure âŁto start the compressor, irregular temperature swingsor diagnostic error codes ârelated âto the temperature sensor. When replacing theâ module, verify theâ sensor â¤resistance at a known â˘temperature against⤠OEM valuesâ and confirm the control’s relay ratings⣠match âtheâ compressor startup load. Useful reference points for technicians and service decisions are summarized below and inâ the table that follows.
- Symptoms: continuous run,no run,erratic cycling,incorrect⣠cabinet temperatures.
- Checks before âreplacement: verify⣠line voltage, inspect connectors and⤠wiring, measure sensor resistance âat room temperature.
- replacement considerations: match connector pinout,control supply voltage,and relay/current rating toâ the original part.

How the 5304497345 Frigidaire Refrigerator Temperature Control Works âInside the Appliance
The 5304497345 Frigidaire Refrigerator Temperature Control is a thermostatic control assembly thatâ senses cabinet or evaporator temperature and âcommands the refrigeration cycle to maintain the selected setpoint. Inside the âpart a temperature sensing element is coupled to a switching mechanism: in some subâvariants the sensor is a resistive⤠thermistor that provides a variable voltage/resistance signal to the main control board, while⣠other variants â¤use an electromechanical switch or bimetal elementâ that⣠directly opens âŁand closes power⣠to âthe compressor relay. The âŁcontrol’s âinternal behavior determines compressor run time,â evaporator fan operationâ and, in models with a damper, air distribution timing;⤠the âphysical mounting â˘and pinout determine whether it provides a lowâvoltage control signal or a lineâvoltage switching output.
- Typical functions: temperature sensing, switching/relay âcontrol, interfaceâ to⢠evaporator⤠fan or damper.
- Common symptoms of failure: persistent⣠warmâ temperatures,compressor that never stops,or compressor that ânever runs.
- Compatibility factors: terminal layout, mounting bracketand whether the unit outputs line voltage or a control signal âfor the electronic board.
| Item | Description |
|---|---|
| Sensor type | Thermistor (electronic) â¤or bimetal/electromechanical (mechanical variants) |
| Switching | Lineâvoltage⤠compressor switching or lowâvoltage signal to controlâ board depending on model |
| Typical voltage | Control signal low-voltage; compressor âswitching typically 120 V AC in North America |
For technicians âŁand⣠appliance owners, practical diagnosis involves confirming that the âcontrol is compatible with the refrigerator’sâ harness and verifying âexpected behavior: colder â˘setpoints increase âŁcompressor duty cycle, while⣠calls for cooling should produce a closure or control signalâ at the part’s âterminals. When replacing this component,⢠match the connector, terminal function âand mounting orientationâ rather than⣠relying solely onâ part⤠numbers; mismatched â˘switching type (line versus low voltage) â¤can âŁprevent proper cycling or damage the control board. Measured resistance⢠characteristics of a thermistor or âcontinuity of the switching contacts during a cooling demand are useful, â˘nonâdestructive checks to determine whether the control itself is operating as⣠intended.
Common âFailure Symptoms and Diagnostic Readings for the temperature Controlâ Assembly
The 5304497345 Frigidaire Refrigerator Temperature Control is a line-voltage thermostat assembly that routes powerâ to the compressor and, wereâ applicable, the evaporatorâ fan and defrost components according to the selected temperature setting. In normal operation the switch produces a distinct contact closure as the cabinet temperature passes the setpoint; commonâ failures are âŁcontact wear (high âŁresistance), welded or stuck âcontacts (closed at all settings)and intermittent contact âloss. â˘Those â¤faults typicallyâ manifest as a refrigeratorâ that runs continuously, never starts, cycles erraticallyor shows large temperature swingsand the part interfaces directly with standard Frigidaire âŁwiring⣠harnesses â˘and compressor relay circuits⣠used on models âŁthat âaccept this âreplacement control.
- No compressor operation: control inputâ has line voltage but the output terminal isâ dead – diagnostic result: open circuit at the thermostat âoutput across all settings.
- Continuous â¤run: compressor receives line voltage irrespective of settingâ – diagnostic result: continuity present at the compressor terminal in all positions (stuck or welded âcontacts).
- Slow cooling or unstable temperature: measurable voltage drop across theâ control under âload – diagnostic result: elevated contact resistance producing several volts drop from âinput to output while running.
- Intermittent âcycling â˘or audible âŁclicking/arcing: continuity âfluctuates when âknob â¤is⤠rotated or under vibration – â˘diagnostic result: inconsistent continuity readings, visible pitting on â˘contact surfaces.
Technicians verify the control with a multimeter andâ safe âisolation of mains power: with power removed, âŁclosed positions⤠should show near-zero ohms continuity to the controlled â¤terminal and open circuit⢠when âthe thermostat is not calling; with⣠power applied and the thermostat calling for cooling, expect⢠approximately 120 VAC at the output terminal relativeâ to neutral. Use aâ loaded voltage measurement (with theâ compressor running) to detect excessiveâ voltage⣠drop â- a healthy mechanical thermostat⤠will show minimal voltage loss, while a failing control can reduceâ compressor voltage enough toâ impair starting or performance. The⤠table below âsummarizes â˘typical expected â¤readings and commonâ failure indications to aid diagnosis.
| Item | Description |
|---|---|
| Normal âcontinuity | Near 0 Ί when âclosed; open/infinite when open |
| Normal operating voltage | ~120 VAC at output when calling for cooling |
| Failure indicators | Open⤠circuit at â˘all settings; continuity in all⢠positions; significant voltage drop under load; visual contact damage |
Replacement Considerations, âModel Compatibility and Step-by-Step âInstallation â¤for the 5304497345 Unit
The 5304497345 Frigidaire Refrigerator temperature Control isâ the electronic/mechanical control that governs âcompressor cycling and evaporator fan operation to maintain setpoint â˘temperatures.â When⤠replacing this⤠component,verify the physical mounting,harness pinout,and sensor type (thermistor versus mechanical bulb) as â¤identical-looking housings can have differentâ internal circuits and connector assignments.⢠Cross-reference the refrigerator âmodel tag and the control’s label toâ confirm âcompatibility; mismatched pinouts or control logic⢠can produce short cycling, no coolingor âimproper defrost timing rather than restoring correct âtemperature regulation.
Installers should follow a⤠methodical procedure that protects the control circuits andâ validates âsystem behavior after replacement.⣠Disconnect mains powerâ before accessing the â˘control module â˘andâ document each wire location or photograph â¤the harness before removal. After fittingâ the⢠new control, reattach grounds and strain reliefs, power the appliance, set the temperature to a mid-range valueand observe compressor/fan on-off intervals and defrost events over â¤several hours; â¤allow up to 24 hours âfor âthe system to stabilize. If the replacement does not reproduce âexpected â¤cycling or temperature drift persists, check harness continuity and the temperature sensor resistance versus theâ manufacturer’s âŁreference values before pursuing additional diagnostics.
- Disconnect⣠power, document wiring,â remove âŁcover,⢠replace control, secure connectors, restore âpowerand observeâ operationâ for 24 hours.

Q&A
What⣠is part 5304497345 and what does it do in a Frigidaire refrigerator?
Part 5304497345 is aâ temperature control thermostat used â¤in many Frigidaire refrigerators. It sensesâ or accepts the user temperature setting and opens or closes the electrical circuit toâ the compressor (and sometimes fans) âto⤠maintain the set temperature. In mechanical systems it is an electromechanical thermostat;⣠in some models it functions as the user control interface to the cooling system.
How can âŁI tell if the 5304497345 temperature control â¤is bad?
Common signs of a⣠failing temperature control include the refrigerator â¤running constantly,⤠notâ running⣠at all, erratic cyclingor the fridge/freezer not reaching â¤the set temperatures.â To confirm,â first rule out⣠userâ error, blocked vents,⣠dirty condenser coilsand low refrigerant. Then test the control with a⤠multimeter:⢠with power âoff, check for continuity between the appropriate terminals while rotating the control through its settings (mechanical units should make/break contacts); â¤if it does not â˘change state or is open at all settings, it is likely faulty.
Where is the âtemperature control â˘5304497345⢠located and how do⣠I âaccess it?
The control is usually mounted in the fresh-food section behind the temperature â˘knob or inside âthe â˘control housing at the top or rear of the compartment. Access typically requiresâ removing â¤theâ knob and a small trim or control â˘panel cover using a screwdriver. Always âŁdisconnect â¤power before opening any panels to avoid shock or âshorting wires.
How âdo I âtest âŁthe 5304497345 with a multimeter âsafely?
Turn the refrigerator off and unplug it. Remove powerâ and access the thermostat terminals. For⤠a continuity test, set the⢠multimeter to continuity/ohms and probe the common and âŁoutput terminals while turning the control from warm to cold; you should see⤠contacts open/close. For an operational test you can â¤(carefully) restore power and check for voltage to the compressor⣠or start relay when the⣠thermostat is set to call for â˘cooling-only do⤠this if⢠you are â˘pleasant working withâ live circuits. If unsure,have a âqualified⣠technician perform âlive tests.
Can I replace 5304497345 myself and what are the basic steps?
Yes, a competent DIYer can replace this part. Basic steps: 1) âUnplug âthe refrigerator. 2) Remove the control knob and control panel trim. 3) âNote or âphotograph â¤the âwire terminal positions. 4) Disconnect the wiring harness or carefully pull off â¤spade⣠terminals. 5) Remove âŁmounting screws and â˘install theâ new control in the same location. 6) Reconnect wires exactly as âthey were, â˘reassemble the panel, restore powerand test.⢠If the refrigerator uses a harness,match connectors; never âswap terminals âunless âŁyou are sure of the âŁwiring.
Is 5304497345 compatible with all Frigidaire models?
No. â˘Compatibility depends on the refrigerator model and year. Always verify compatibility using the refrigerator model ânumber and cross-reference the part number with Frigidaire/OEM parts lists âor a reputable parts âsupplier. Using⢠the wrong⢠control can â¤cause â¤improper operation or electrical â¤issues.
How long after replacing 5304497345 should I expect⢠normal temperatures?
After â¤replacing the control, allowâ at âleast 24â to 48 hours for temperatures to stabilize, though you may see betterment sooner. The compressor and evaporator must run long enough to remove the existing heat â˘load; avoid frequent⢠door openings during this period and wait before making further adjustments.
Could the âproblem be something else besides the temperature control?
Yes. Similar symptoms can⣠be caused by a failed start relay or compressor, a â¤bad thermistor â˘(on electronically controlled models), a faulty âmain control board, clogged condenser coils, poor airflow from blockedâ ventsor low refrigerant.Diagnoseâ systematically: check coils and airflow, âlisten for compressor behavior, test the controland use the model’s wiring diagram to âŁisolate which component âŁisâ actually failing.
