XPARTCO 5303918202 Refrigerator Defrost Thermostat
The XPARTCO 5303918202 is an aftermarket replacement defrost thermostat kit for Frigidaire, Kenmore, Crosley, Westinghouse, Gibson, Kelvinator, Electrolux, and Tappan refrigerators. This is a bi-metal thermostat that clips directly onto the evaporator coil and monitors its temperature during the defrost cycle. It works alongside the defrost timer and defrost heater: once the timer calls for defrost, this thermostat confirms the coil is cold enough to safely apply heat, allows the heater to run, and then cuts power to the heater once the coil has warmed past its threshold — protecting the evaporator from overheating during that process.
This is a clip-on style thermostat, internally designated L47-22F, and ships as a complete kit including the thermostat, wire connectors, and heat shrink tubing for the connections. The classic symptom of a failed defrost thermostat is distinctive: the freezer stays cold while the fresh food refrigerator section runs warm, since frost accumulating unchecked on the evaporator coil blocks airflow and starves the refrigerator side of cold air. Icy, frost-caked evaporator coils are another clear sign of the same underlying problem. It directly replaces 241619705, AP2150133, 833603, PS469510, and EAP469510.
Quick Answer
The XPARTCO 5303918202 Refrigerator Defrost Thermostat fixes Frigidaire, Kenmore, Crosley, Westinghouse, Gibson, Kelvinator, Electrolux, and Tappan refrigerators where the freezer stays cold but the fresh food section runs warm, the evaporator coils are icy or frost-caked, or water is leaking inside the fresh food section. Clip-on style, internal designation L47-22F. Complete kit with wire connectors and heat shrink tubing. Replaces 241619705, AP2150133, 833603, PS469510, EAP469510. This is a clip-on thermostat — not the same mounting style as our tube-mount 242046001 listing, even though both share the L47-22F designation.
Common Problems This Part Fixes
- Freezer stays cold but the fresh food refrigerator section runs warm
- Evaporator coils covered in ice or heavy frost
- Refrigerator not cooling properly overall
- Freezer section not defrosting on its normal cycle
- Water leaking inside the fresh food section from melting ice buildup
- Refrigerator running constantly as ice-caked coils reduce cooling efficiency
- Fridge and freezer both running too warm, or freezer running too cold
Cross Reference Information
Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item.
Replaces Part Numbers
This refrigerator defrost thermostat directly replaces the following OEM and cross-reference part numbers:
5303918202, 241619705, 833603, AH469510, AP2150133, AFR16814, PD00000180, EA469510, PS469510

Compatibility
This defrost thermostat is compatible with select Frigidaire refrigerators and freezers, and also fits select Kenmore, Crosley, Westinghouse, Gibson, Kelvinator, Electrolux, and Tappan refrigerators and freezers built on the same platform.
Note — clip-on style, not tube-mount: This thermostat clips directly onto the evaporator coil. It is a different mounting style from our 242046001 listing, a tube-mount defrost thermostat — even though both share the same internal L47-22F temperature designation, they attach to the coil differently and are not interchangeable. This part is also distinct from the related 5303918214 thermostat (replaces 892545, AP2150145, PS469522), used on other Frigidaire models. Always verify your full model number before ordering. Contact our support team with your model number if you're unsure which thermostat fits your refrigerator.

Installation Notes
Frequently Asked Questions
My freezer is cold but the fridge is warm. Is this the defrost thermostat?
Yes, this is the single most common and telling symptom of a failed defrost thermostat. When this thermostat fails, the defrost heater can't run correctly to clear frost from the evaporator coil, and heavy ice buildup on the coil blocks the airflow that's supposed to carry cold air to the fresh food compartment. The freezer, sitting right next to the coil, often stays reasonably cold on its own, while the fresh food side — which depends entirely on that circulated air — runs warm.
Is this the same thermostat as your 242046001 listing? They both say L47-22F.
No, and this is worth being careful about. Both thermostats share the same L47-22F internal temperature designation, meaning they open and close at the same threshold, but they use different mounting styles — this 5303918202 clips directly onto the evaporator coil, while the 242046001 is a tube-mount design that attaches differently. The mounting style has to match your refrigerator's original thermostat, so check how your old thermostat attaches to the coil before ordering either one.
Do I need special tools for this repair?
Yes, a few beyond the basics. This kit includes wire connectors and heat shrink tubing, so you'll need wire strippers and crimpers to make the splice and a heat gun to shrink the tubing over the finished connection for a secure, insulated joint. A 1/4" nut driver is also needed to remove the rear access panel.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Frigidaire OEM part, but is manufactured to match the L47-22F temperature designation, clip-on mounting style, and kit contents of the original 5303918202 defrost thermostat used in compatible Frigidaire, Kenmore, Crosley, Westinghouse, Gibson, Kelvinator, Electrolux, and Tappan refrigerators.
