  • Sale -24%Last stock! 5303918214 Refrigerator Genuine OEM Defrost Thermostat  Parts-O-Matic

    Frigidaire 5303918214 Refrigerator Genuine OEM Defrost Thermostat

    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 Cross Reference Information Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models.

Key Features Genuine Frigidaire OEM part — factory-specified temperature threshold and mounting configuration Defrost thermostat kit for Frigidaire-platform refrigerators with an ice maker Monitors evaporator coil temperature and controls power to the defrost heater Resolves "freezer cold, fridge warm," "not defrosting on schedule," and "icy evaporator coils" symptoms caused by thermostat failure Ships with wiring diagram guidance for a correct connection Direct drop-in replacement — mounts to the original housing location Replaces AP2150145, 892545, AH469522, EA469522, PS469522, and 75303918214 Compatible with Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Westinghouse, and Crosley refrigerators Genuine OEM replacement — guaranteed fit, materials, and performance Product Specifications Part Number 5303918214 Part Type Refrigerator Defrost Thermostat Kit Condition Genuine OEM Function Monitors evaporator coil temperature and controls power to the defrost heater Typical Location Rear access panel area, near the ice maker on many compatible models Repair Difficulty Moderate — ice maker removal typically required for access Quantity 1 defrost thermostat kit Compatible Brands Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Westinghouse, Crosley Installation Notes ⚠️ Unplug Refrigerator And Shut Off Water Supply Before Starting Unplug the refrigerator from the wall outlet and turn off the water supply to the refrigerator before beginning. Wear work gloves. If your model has an ice maker, remove it first using a screwdriver to gain clearance for the next steps. Remove the back panel with a screwdriver to expose the defrost thermostat. Take out the existing thermostat and disconnect its wiring, labeling or photographing each connection first. Install the new 5303918214 thermostat by connecting the wires according to the wiring diagram provided with the kit, then secure the thermostat to the main housing using the small mounting screws. Reinstall the back panel, plug the refrigerator back in, turn the water supply back on, and reinstall the ice maker. Test the refrigerator over the following day to confirm both compartments are cooling evenly and the defrost cycle is running normally. Tools needed: screwdriver, wire cutters/strippers, work gloves. 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.
