5303918214 Genuine OEM Frigidaire Refrigerator Defrost Thermostat
The 5303918214 is a genuine Frigidaire OEM defrost thermostat kit for Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Westinghouse, and Crosley refrigerators — commonly used on side-by-side and French door models equipped with an ice maker. This thermostat monitors the temperature of the evaporator coils: when the coils drop below a set temperature, it allows power to reach the defrost heater so frost can be cleared; once the coils warm back up, it cuts power to the heater again, protecting the evaporator from being overheated during that process.
The most common reasons this thermostat gets replaced are a classic pair of symptoms: the freezer stays cold while the fresh food refrigerator section runs warm, or the refrigerator simply isn't defrosting on its normal cycle. Because this thermostat sits behind the rear access panel near the ice maker on many compatible models, replacing it typically involves removing the ice maker and the back panel to reach it — a more involved repair than a thermostat mounted in an easily accessible spot. It directly replaces AP2150145, 892545, AH469522, EA469522, PS469522, and 75303918214. As a genuine OEM part, the 5303918214 is manufactured by Frigidaire to factory specifications — guaranteed fit, materials, and performance.
Quick Answer
The 5303918214 Genuine OEM Frigidaire Refrigerator Defrost Thermostat fixes Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Westinghouse, and Crosley refrigerators where the freezer stays cold but the fresh food section runs warm, or the refrigerator isn't defrosting on its normal cycle. Replaces AP2150145, 892545, AH469522, EA469522, PS469522, 75303918214. This is a separate part from our 5303918202 defrost thermostat listing — the two fit different model groups and are not interchangeable. Installation on many compatible models requires removing the ice maker to access the thermostat.
Common Problems This Part Fixes
- Freezer stays cold but the fresh food refrigerator section runs warm
- Refrigerator not defrosting on its normal cycle
- Excessive frost or ice buildup on the evaporator coils
- Refrigerator or freezer not cooling properly overall
- Water leaking inside the refrigerator from melting ice buildup
- Refrigerator running constantly as ice-caked coils reduce cooling efficiency

Installation Notes
Frequently Asked Questions
Do I really need to remove the ice maker for this repair?
On many compatible models, yes — the thermostat sits behind the rear access panel in an area that the ice maker partially blocks, so removing it first gives you the clearance needed to reach the panel and the thermostat behind it. It's an extra step compared to some simpler defrost thermostat replacements, but it's a standard part of this particular repair.
My freezer is cold but the fridge is warm. Is this the thermostat?
Yes, this is the classic symptom of a failed defrost thermostat. When it fails, the defrost heater can't run correctly to clear frost from the evaporator coil, and the resulting ice buildup blocks the airflow that's supposed to carry cold air to the fresh food compartment. The freezer, sitting closer to the coil, often stays reasonably cold, while the fresh food side runs warm since it depends on that circulated air.
I replaced the thermostat but my freezer temperature is still fluctuating. What should I check next?
Replacing this thermostat resolves the issue for most customers, but if fluctuation continues, it's worth checking the other components in the same defrost circuit — the defrost timer and defrost heater — since a failure in either of those can produce similar temperature instability even with a good thermostat installed. It's also worth confirming the door seals are sealing properly, since a poor seal lets warm air in and can cause temperature swings unrelated to the defrost system.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by Frigidaire to factory specifications — guaranteed fit, materials, and performance. It matches the original temperature threshold, mounting configuration, and function of the defrost thermostat originally installed in your refrigerator.
