5304497345 Frigidaire Refrigerator Temperature control is a temperature-control âassemblyâ used to regulate the âinternal habitat âof compatible Frigidaire refrigerators. Depending on model âand generation,â the component may be implemented as an electromechanical thermostat or as an electronic control/thermistor assembly; the part number designates a specific replacement control that mounts in the refrigerator’s control housing â˘and interfaces with the cabinet’s temperature-sensing element and âwiring harness.
Inside the appliance, the temperature control monitors air or evaporator temperature and issues switching commands that start and stop refrigeration system components. It typically interacts âwith the âevaporator fan, compressor (through âa relay or the⤠main control board), the fresh/vent damper,⢠and, in some models, âdefrost and ice-maker circuits. Proper operation requires correct sensor readings, stable supply voltage and intact âŁwiring; the control provides hysteresis or⢠timedâ cycling to â˘prevent short-cycling of the compressor and to maintain a steady setpoint across the fresh-food â¤and freezer compartments.
In this article you will find a technical⣠overview of the 5304497345 control’s function, guidance on model compatibility and identifying the âŁcorrectâ replacement, common failure symptoms (for example, no cooling, constant run, incorrect setpoint response, excessive frostingor intermittent âcycling)and structured troubleshooting steps such as power and continuity âchecks, sensor resistance verificationand voltage measurementsâ to downstream components. The piece will also cover practical replacement considerations-connector and mounting âŁcompatibility, calibration âor â˘setpointâ verification after installationand basic safety precautions to observe during diagnosis and repair-so technicians, engineersand informed appliance owners can evaluate and addressâ control-related issues⤠effectively.

Functional Role and Electrical and Mechanical Requirements of the Temperature Control Assembly
The 5304497345 Frigidaire⢠Refrigerator Temperature Controlâ functions as the user-adjustable setpoint and primary switching device that governs â˘compressor operation, evaporatorâ fan controland in some models the defrost sequencing or signal inputs to âan electronic control board. It senses temperature through an internal sensing element (mechanical bimetal, bulb/capillaryor an electrical sensor⢠depending on the model) and closes or opensâ contacts to âcontrol line-voltage loads or to provide logic-level signals. When replacing or troubleshooting this part, match the sensing method, âterminal âarrangement,â mounting styleand the stamped electrical ratings to ensure correct behavior and safe operation; a⢠correct physical and electrical⤠match prevents improper cycling, inadequate coolingor damage to the compressor starterâ components.
Electrical and mechanical requirements for reliable operation include robust contact ratings for mains⣠switching,low âcontact resistance to avoid voltage drop and heat buildup,secure spade or plug-in terminals â˘for â˘vibration resistance,and a temperature differential (hysteresis) appropriate to the refrigerator compartment to prevent short cycling. Mechanical integrity of the sensing element and proper enclosure sealing maintain accuracy in humid or cold environments; wear or contact pitting can cause intermittent âoperation, long run-timesor failure to start. For practical diagnosis, verify terminal voltages under load, âŁcontinuity of switched circuits at different setpointsand visual condition of terminals and mounting clips to determine whether the control isâ the root cause or a symptom of another electrical issue.
- Compatibility checklist: confirm terminal labeling, sensing methodand electrical ratings match the original part.
- Commonâ symptoms of â˘a failing control: continuous run, frequent short cycles, inability to change temperature with the knobor no âcompressor start.
- Inspection steps: measure continuity and switching under load, inspect for burned or loose terminals, compare physical mount and connector type.

How the 5304497345 Frigidaire Refrigerator Temperature âControl Works Inside the⤠Appliance
5304497345 Frigidaire Refrigerator Temperature⤠Control ⣠is the⤠user-accessible control and internal switching assembly that regulates compressor and fan operation by responding to temperature feedback âŁfrom the cabinet or evaporator sensor. Internally it combines a setpoint-adjustment mechanism with a sensing element (commonly âa thermistor or a mechanical sensing element in legacy controls) and⢠one or more⢠switching contacts or low-voltage control outputs. When the sensed temperature rises above the selected setpoint the control completes the circuit to the compressor relay⣠(and the evaporator fan if controlled together)and when the temperature falls below the setpoint⢠minus the control’s differential it opens the circuit to halt cooling; this â˘on/off behavior defines the appliance’s duty cycle and steady-stateâ temperature⤠control.
The control’s practical behavior includes a built-in hysteresis (temperature âŁdifferential) and often â˘an âanti-short-cycle delay that prevents the compressor from starting too frequently. Compatibility for replacement â˘hinges on matching electrical ratings, connector harness pinout, mounting âfootprintand the type of sensor input the âŁrefrigerator uses; substituting a control with different switching logic or voltage can produce continuousâ running, rapid short-cyclingor disabled defrost circuits. Technicians commonly verify correct operation by measuring supply voltage to the â¤control, observing switching across the control’s output terminals under⤠changing temperature conditionsor temporarily simulating sensor temperatures to confirm the compressor and fans âŁrespond âŁas specified.
- Key features: setpoint adjustment, sensing input⣠(thermistor or mechanical), switching outputs, hysteresis/differential, anti-short-cycle delay.
- Common failure indicators: refrigeratorâ too warm, compressor runs continuously,â compressor does not start, â˘erratic temperature swings.
- Replacement considerations: match voltage rating, â¤connector pinout, â˘and control logic to the appliance wiring âdiagram.

Common Failure Symptoms,Measured Fault Indicatorsâ and Diagnostic Test Points
The 5304497345 Frigidaire Refrigerator Temperature Control is theâ user-settable control moduleâ that senses cabinet temperature and⤠issues the control signals that startâ and stop the compressor,evaporator fan and,where applicable,the defrost sequence. In practical terms this part translates a temperatureâ sensor input (thermistor or internal switch) into a⣠line- or low-voltage output to downstream components; replacement must match the ârefrigerator’s connector⤠pinout and mountingâ arrangement to ensure proper integration with the compressor relay, âŁfan circuitâ and any existingâ defrost control.Technicians should verify harness compatibility and examine the sensor interface and mounting points âŁwhen diagnosing a suspected control â˘failure,since identical-looking controls can have different internal wiring or sensor expectations across Frigidaire models.
Common failure modes manifest as specific symptoms and measurable fault indicators that guide diagnostic test⣠points. Typical signs include a warm cabinet with an idle compressor (control not calling⤠for compressor), a⣠running compressor â¤with continuous overcooling â(control⢠stuck closed)or intermittent cooling and short cycling (failedâ relay or intermittent sensor). Useful diagnostic actions are: verify the presence of the control’s output at the compressor relay/harness when the thermostat is⣠turned colder, confirm the thermistor orâ sensor shows a temperature-correlated change in resistanceand check continuity across âany mechanical âŁswitch contacts while âactuating the control. Also inspect connector terminals for corrosion or mechanical damage-loss of contact can produce identical symptoms to an internal control failure.
- Warm refrigerator, fan running but compressor off – â¤test for control output at compressor relay/harness when set colder; check for open relay or âmissing line-voltage âŁsignal.
- Compressor âŁruns continuously or freezer overfreezes âŁ- check whether the control output remains closed continuously; verify⤠sensor resistance vs. temperature to rule out a stuck sensor â˘or shortedâ input.
- Intermittent cooling âor short cycling – probe for looseâ connectors, intermittent continuity â¤on switch contactsand⢠fluctuating sensor readings âunder steady ambient conditions.
- Control unresponsive to user adjustments – confirm proper connector pinout, check for continuity on control knob/switch assemblyand measure control board supply voltages.
| Item | Description |
|---|---|
| Control output to compressor | Line- or low-voltage signal â˘supplied when thermostat calls âŁfor cooling; measure presence at relay/harness as the primary functional âtest. |
| Thermistor / sensor | Resistance should change predictably with temperature; a fixedâ or open reading indicates⣠a failed sensor or⤠open circuit between sensor andâ control. |
| Mechanical/electrical switch continuity | When the control is moved to colder settings theâ internal switch or relay contacts should show continuity; intermittent or no continuity indicates internal failure⣠or â¤wiring defect. |
Compatibility, Replacement Considerations and StepâbyâStep Installation Procedures
The 5304497345 Frigidaire Refrigerator Temperature Control functions as the temperature âŁsensing and switching element that regulates compressor and fan operation to maintain the cabinet⤠setpoint. In practice this component either contains an internal electronic sensor or a capillary/bulb sensorâ and a switching mechanism (mechanical or solidâstate) that âopens and closes the cooling circuit based on the sensed temperature and the control’s differential (hysteresis). Fault modesâ you will observe on a failed â˘control include continuous compressor operation, failure to call for cooling, ârapid shortâcyclingor âerratic temperature swings; these behaviors reflect either a failed sensing element, â˘a stuck switchor poor electrical contactâ rather then a refrigeration system fault in most âcases.
When replacing or evaluating compatibility, confirm mechanical mounting, connector pinoutand whether the control is a direct match or a functional equivalent; identical part numbersâ ensure correct calibration â¤and electrical interface, while substitutes require verification of terminal assignment and switching type. For field replacement, follow basic troubleshooting and installation steps:
- Disconnect power to the appliance before accessing the control to prevent electrical shock âand compressor damage.
- Document and label wiring and â˘take a photo of the harness orientation; match each terminal on the replacement unit.
- Remove retaining screws and transfer any mounting brackets or insulation to preserve âairflow and sensor placement.
- Install â˘the replacement, reconnect wiring, restore powerand observe the first few on/off cycles; verify â¤compressor and evaporatorâfan operation and âallow â¤several hours for temperature stabilization.

Q&A
What is part 5304497345 and what does the Frigidaire refrigerator temperature âcontrol do?
Part 5304497345 is the temperature control (thermostat or temperature selector) used on some Frigidaire refrigerators. â˘it senses âor selects the user temperature setting and completes or opens the electrical circuit that â¤tells the compressorâ and fans to run. In short, it controls cycling of the coolingâ system so the cabinet stays at the selected temperature.
What are common symptoms that the â˘5304497345 temperature control is failing?
common symptoms include: refrigerator too warm or too cold despite setting changes; compressor not coming âon at â¤anyâ setting;⤠compressor running continuously; or temperature fluctuating erratically. You⤠may also notice that changing theâ temperature dial has no effect. Those symptoms can come from the control, but from other components too (thermistors, âcontrol boards, start relays, fans, sealed system⢠issues).
How can I⢠test the 5304497345 temperature control with a multimeter?
First disconnect power.â Removeâ the control and identify its terminalsâ using the wiring diagram on the⤠appliance or the control label. Set a multimeter to continuity or low⤠ohms. With âthe control set to a cold/call position (highest cooling), you should see continuity betweenâ the common and the contact that âcloses when cold. With the control set to warm, that contact should âŁopen. Exact terminal designations vary, so consult the wiring diagram. If the control does not change state or is âopen/shorted at all settings it is likely faulty.
Where is âthe temperature control located in a Frigidaire refrigerator and how hard is it to replace?
The control is⣠usually behind the ârefrigerator’s temperature knob inside the fresh food compartment,or behind the top⢠interior control panel. Replacement generally requires â˘removing the knob and trim, disconnecting the wiring harness or spade terminalsand swapping the control. The job is typically straightforward âŁfor someone comfortable with basic tools, but always disconnect â¤the refrigerator from power first and confirm the replacement part is compatible⤠withâ your model.
Is the â5304497345 control compatible with âall⢠Frigidaire â¤models?
No.5304497345 fits specific Frigidaire/Frigidaire Gallery models. âAlways verify compatibility by âŁchecking yourâ refrigerator model number (on the inside wall or behind the kickplate) against the part listing or manufacturer crossâreference. If your refrigerator âuses an âelectronic â¤control board and thermistors instead of a mechanical thermostat, this part will⣠not be compatible.
Will replacing the temperature control fix a refrigerator that is too warm?
Possibly, but not always. If the control has failed to call for cooling, replacing it can restore normal operation. However, warm temperatures can also be caused by other issues: âfailed compressor start⣠relay, sealed system leak, evaporator fan failure, clogged condenser,â iced evaporator, bad defrost â˘systemor door/airflow problems. Diagnose other systems (compressor run, fans, âcondenser coils, defrost) before assuming the âthermostat isâ the only cause.
How â¤should I set and calibrate the temperature after installing 5304497345?
Set the control to the recommended midpoint⢠or manufacturer-recommended âsetting,allow â¤the refrigerator to stabilize for 24 hours with a thermometer âplaced in the center shelf,then adjust⤠the dial up or down in small increments and wait â24 hoursâ between adjustments.If âŁthe⣠temperature still runs consistently âoff by several degrees, recheck door seals, airflowand other components; some âmodels have a separate calibration screw⤠or procedure-consult the service manual for model-specific instructions.
Are there any safety tips or precautions when replacing the temperature control?
Yes. disconnect power beforeâ servicing to avoid electrical shock. Avoid bending or damaging wiring and terminal tabs. Make note or take âa photo of⤠wiring locations before disconnecting so you can reconnect correctly. If you are not comfortable working with â˘electrical components, hire a qualified appliance technician. Also ensure the replacement part matches the⢠model number and terminal configuration to prevent damage to the refrigerator.
