5304497345 Frigidaire Refrigerator Temperature Control is a temperature-regulation assembly used in Frigidaire refrigeration units; it functions as the user-adjustable thermostat or control interface that determines when the refrigeration system should run to maintain a selected cabinet temperature. The part typically combines a sensing element and a switching mechanism-either electromechanical contacts or an electronic sensor/interface-mounted behind the temperature knob or within the control housing to provide a setpoint and hysteresis for compressor cycling.
Inside the appliance, the temperature control senses air or evaporator temperature and interfaces with the compressor start/stop circuit or the main control board, thereby governing compressor runtime and cycle frequency.It also affects related subsystems such as the evaporator fan, air damper and defrost control logic by determining when cooling is called for; consequently, its setting and performance influence cabinet stability, compressor duty cycle and interactions with defrost and air-distribution systems. Failures or miscalibration at this control can produce symptoms ranging from continuous compressor operation to inadequate cooling or excessive short-cycling.
In this article readers will find a technical examination of the component’s intended function, guidance on verifying compatibility with specific frigidaire models, common failure modes and observable symptoms, step-by-step troubleshooting checks (continuity, sensor resistanceand control-voltage verification), and practical replacement considerations such as part-number matching, connector and mounting verificationand safe power-isolation procedures. The focus is on diagnostic methods and replacement criteria that technicians, engineers and informed appliance owners can apply in the field.

Function and Role of the Temperature Control Assembly in Frigidaire Refrigeration Systems
The 5304497345 Frigidaire Refrigerator Temperature Control is the thermostat/control assembly that regulates cooling by completing or interrupting the electrical circuit to the compressor and evaporator fan according to the selected setpoint. In mechanical implementations the control operates an internal switch driven by a temperature-sensing element or bimetaland in systems with an electronic control board the assembly frequently enough serves as the user interface and connector that relays the temperature demand to the board. Correct matching of the part number, connector styleand electrical ratings to the refrigerator model is necessary to ensure expected cycle duration and stable cabinet temperatures; a mismatched assembly can produce incorrect cycling or connector stress.
Functionally,the assembly governs on/off cycling,influences duty cycle and temperature hysteresis,and can affect defrost timing when integrated with other control functions. Typical diagnostic checks include rotating the selector while measuring continuity, confirming presence of supply voltage at the control during a call for coolingand observing compressor run/stop behavior under controlled load. Replacement decisions should consider connector compatibility, mounting orientation, and documented electrical specifications rather than cosmetic similarity; swapping an assembly with differing switch ratings or terminal layout can create intermittent faults or premature failure.
- Common symptoms: short-cycling, continuous run, inability to reach setpointor audible clicking at the control.
- Diagnostic actions: continuity check across terminals while changing dial, verify harness voltage, inspect for corrosion or loose pins.
- Replacement consideration: confirm harness and terminal mapping before installation.

How the 5304497345 Frigidaire Refrigerator Temperature Control Works Inside the Appliance
The 5304497345 Frigidaire Refrigerator Temperature Control is the user-facing control device that senses internal temperatures and completes or interrupts electrical circuits to the compressor, evaporator fan, and related load circuits to maintain setpoint. It typically contains a sensing element (either a thermistor or a mechanical sensor assembly), a temperature setpoint interfaceand switching contacts or an electronic output that drive the compressor relay and fan motor. in operation the control monitors the sensed temperature and changes state at defined thresholds so the refrigeration system cycles on and off to hold the cabinet and freezer temperatures within a controlled band; this behavior is the same functional role across compatible Frigidaire models even where the internal implementation (electromechanical vs. electronic) differs.
Technicians use straightforward checks to verify correct behavior and compatibility: measure continuity or voltage at the control’s output when the sensed temperature crosses the setpoint,confirm proper cycling interval under normal load,and match connector style and control ratings when replacing the part. Common symptoms of a failing control include continuous compressor operation, failure to start the compressor, or large temperature swings in one compartment. Practical diagnostic steps and features to consider are listed below.
- features: setpoint adjustment range, contact ratings for compressor/fan, sensing element type.
- Symptoms of failure: no compressor run, compressor runs continuously, inconsistent cycle timesor compartment temperature drift.
- basic checks: continuity across switch terminals at cold/warm conditions, voltage presence to compressor relayand physical inspection of connectors and mounting.

Common Failure Symptoms, Electrical Signatures and Mechanical Indicators
The 5304497345 Frigidaire Refrigerator Temperature Control is an electromechanical thermostat assembly that senses cabinet temperature and switches power to the compressor, evaporator fanand related circuits. In many Frigidaire models this part is a direct replacement and shares the same mounting footprint and terminal configuration; technicians should confirm terminal count and connector style against the old unit before installing. the control uses a temperature-sensing element (a capillary/bulb or an internal sensor depending on the revision) to actuate a multi-position switch: as the setpoint is moved colder the switch closes more frequently or for longer intervals to call for coolingand when the sensed temperature reaches the setpoint the contact opens to stop the compressor circuit.
Common failure modes produce characteristic symptoms and measurable electrical signatures. Mechanical wear or a broken shaft and knob typically show as lost detents or inability to change setpoint, while contact wear or corrosion appears as intermittent continuity, high resistanceor an open circuit across the control terminals. With the refrigerator calling for cooling you should measure line voltage at the control output (typically ~120 VAC on US mains) to the compressor relay; absence of voltage at a cool call indicates a failed switch or internal open. Disconnect power before performing continuity or resistance checks, and use a meter to verify continuity across the common and cool-call terminals as you rotate the control – a properly functioning control will show predictable continuity changes across positions rather than random open/close behavior.
- Intermittent cooling or short cycling: worn internal contacts causing rapid on/off behavior
- No cooling while compressor does not receive voltage: open switch or broken internal connection
- Continuous run: stuck-closed contact or incorrect sensing element response
- Loose knob or no click between positions: mechanical shaft/ detent failure
- Visible damage (burn marks,corrosion) or ruptured capillary: mechanical failure or loss of sensing integrity
| Item | Description |
|---|---|
| Continuity test | Common-to-cool terminal should show continuity at colder settings and open at warmer settings; intermittent continuity indicates contact wear |
| Line voltage check | With system calling for cooling,meter should read supply voltage on the output terminal feeding the compressor relay; no voltage suggests internal open or failed switch |
| Mechanical inspection | Shaft looseness,burned terminals,or a ruptured capillary point to replacement rather than repair |
Compatibility,Replacement Considerations and Step‑by‑Step Installation Guidelines
The 5304497345 Frigidaire Refrigerator Temperature Control is the electromechanical/electronic switching device that dictates compressor and evaporator fan operation by changing contact states based on measured cabinet or evaporator temperature.In many Frigidaire designs this assembly either contains a calibrated thermostat or interfaces to a thermistor input and switching relay; replacement compatibility depends on matching the connector pinout, mounting footprintand control logic (line‑voltage switching versus low‑voltage signal control). Technicians should compare the part number, wiring harnessand the appliance schematic before ordering; mismatched controls can produce continuous compressor operation, intermittent coolingor prevent the defrost cycle from initiating correctly.
- disconnect mains power and document connector positions and wire colors before removal.
- Remove control knob/trim, unfasten the control module, and gently extract the harness to access terminals.
- Bench‑test the removed control with a multimeter for expected continuity or resistance changes across setpointsor verify thermistor resistance against the service manual table.
- Install the replacement by reversing removal steps, secure mountingand restore power; observe compressor and fan operation and measure refrigerant circuit temperatures over several hours to confirm proper control behavior.
During installation validate that the replacement unit replicates the original’s switching characteristics and terminal labeling; if the original used a thermistor, confirm the new control reads the same resistance at a given temperatureand if it switches line voltage, verify the relay contacts carry the compressor line.After installation, monitor evaporator coil temperature and cabinet setpoint response rather than relying solely on immediate compressor cycling – for example, a correct repair typically shows the compressor run until coil temperature falls into the expected range and then open the circuit, with a refrigeration pull‑down of several degrees over a few hours. If the symptom persists, inspect related components (start relay, run capacitor, door gasketand evaporator airflow) before replacing the control again.

Q&A
What is the 5304497345 Frigidaire Refrigerator Temperature Control and what does it do?
Part 5304497345 is the temperature control assembly used in certain Frigidaire refrigerators. Its job is to monitor the refrigerator/freezer temperature (directly or via a temperature sensor/thermistor) and switch the compressor, evaporator fan or other cooling circuits on and off to maintain the set temperature. In simple terms it is the component that tells the cooling system when to run and when to stop.
What common symptoms indicate the 5304497345 temperature control might be failing?
Symptoms include: the compressor or evaporator fan never turns on, cycles on and off excessively, the refrigerator is too warm or freezes food, or temperature does not change when you adjust the temperature dial/setting.Visual signs such as burned connectors or melted plastic around the control are also indicators. Keep in mind other parts (thermistor, start relay, control board, door seals) can produce the same symptoms.
How can I test the 5304497345 temperature control to confirm it is indeed bad?
Safety first: unplug the refrigerator before testing. Locate and access the control (usually inside the fridge, rear wallor behind the kickplate). Do a visual inspection for damage. using a multimeter you can check for continuity: with the control set to a cold/call-for-cool position the control should show continuity across the switching contacts; when set to warm it should open.If the control uses a sensor/thermistor, measure its resistance and compare to the manufacturer’s specification or service manual at a given temperature. Also verify there is proper line voltage to the control when the fridge is plugged in (do that onyl if comfortable and with power on). If tests show no switching or out-of-spec sensor readings, the control is likely faulty.
can I recalibrate or adjust the 5304497345 temperature control if temperatures are off?
Most temperature controls are not field-calibratable beyond the user temperature dial or setting. For mechanical thermostats you can change the setting incrementally. For electronic controls some models have a service menu/calibration accessible only to technicians. If the unit is consistently off by a large margin, first check door seals, airflow, condenser cleanliness and thermistor placement-if those are correct the control or its sensor is highly likely defective and should be replaced rather than calibrated.
How do I replace the 5304497345 temperature control safely and correctly?
Always unplug the refrigerator before beginning.Remove the interior cover or kickplate to access the control, take pictures of wiring or label wires, then disconnect connectors. Remove the old control and install the new part in the same orientation. Reconnect wiring exactly as removed,reassemble panels,plug the fridge back in and allow several hours for temperatures to stabilize. Do not attempt to open or service sealed refrigeration components-if you need to access the compressor or refrigerant lines, call a certified technician.
How do I verify that part 5304497345 is the correct replacement for my Frigidaire model?
Check your refrigerator’s model and serial number (usually on a sticker inside the fridge or on the door jamb).Use that model number to look up parts on the official Frigidaire parts lookup, an authorized parts dealeror the service manual. cross-references and compatibility lists will confirm if 5304497345 fits your exact model. If in doubt, provide the fridge model number to the parts supplier or technician before ordering.
What tools and precautions are required to test or replace this control?
Basic tools: screwdriver set, nut driver, needle-nose pliersand a multimeter. Precautions: unplug power before disassembly, label or photograph connectors before removal, avoid touching refrigerant lines or compressor components, and observe basic electrical safety when measuring line voltage. If you are not comfortable working with mains electricity or internal appliance wiring, hire a qualified appliance technician.
Could a bad 5304497345 temperature control cause the compressor to run constantly or not run at all?
Yes. If the control is stuck closed it can power the compressor continuously; if it is stuck open it can prevent the compressor from starting. However, similar behavior can be caused by a failed start relay, a bad thermistor, a faulty control boardor issues with the compressor itself. Proper troubleshooting (visual inspection,multimeter checks of the control and related parts,and verifying voltage to the compressor) is needed to identify the exact cause.
To Wrap It Up
The 5304497345 Frigidaire refrigerator temperature control plays a central role in regulating the appliance’s cooling cycle by sensing or commanding temperature setpoints and signaling the refrigeration system to run or idle. As a control component, it helps maintain consistent interior temperatures across compartments, coordinating with sensors, fansand the compressor to achieve the desired environment for food storage.
Reliable operation of this control is vital for food safety, product qualityand energy efficiency. When the temperature control functions correctly, it prevents unneeded compressor cycling, reduces wear on mechanical componentsand helps avoid temperature excursions that can lead to spoilage or uneven cooling. Conversely, a faulty control can produce fluctuating temperatures, increased energy useand stress on other components of the refrigeration system.
Because temperature-related problems can arise from multiple causes,proper diagnosis is essential before replacing the control. Verifying the control with appropriate tests, checking related parts such as sensors, evaporator fans, defrost systems and the main control board, and following manufacturer guidance reduces the chance of unnecessary replacement. When testing indicates the temperature control is the root cause, replacing it with the correct, compatible part and following safe installation practices restores consistent performance and prolongs appliance life.
the 5304497345 Frigidaire temperature control is a key element in maintaining refrigerator performance; accurate diagnosis and,when required,timely replacement ensure temperature stability,efficient operation,and protection of stored food. For complex or uncertain issues, consult qualified service personnel to ensure safe and effective repair.
