XPARTCO WR51X10055 Refrigerator Defrost Heater Assembly
The XPARTCO WR51X10055 is an aftermarket replacement refrigerator defrost heater and bracket assembly compatible with a wide range of GE, Hotpoint, Kenmore, Haier, Americana, Monogram, and Café refrigerators. The defrost heater is a glass quartz tube heater mounted on a bracket below the evaporator coils in the freezer compartment. During each automatic defrost cycle, the heater energizes and melts any frost that has accumulated on the evaporator coils — maintaining unobstructed airflow through the coils so the refrigerator can cool efficiently. When the heater fails, frost accumulates on the coils unchecked, blocking airflow and causing both the freezer and fresh food sections to gradually warm up.
Rated at 120V, 725W, this single quartz tube heater assembly measures 12-1/8" L x 3-3/8" W x 2-1/8" H and includes the heater element and mounting bracket. It directly replaces WR51X10030, AP3183311, 914088, AH303781, EA303781, PS303781, SH323, and EAP303781. Often replaced together with the defrost thermostat (WR50X10068) and temperature sensor (WR55X10025) for a complete defrost system repair. Installs in 20–30 minutes with basic hand tools.
Quick Answer
The XPARTCO WR51X10055 Refrigerator Defrost Heater Assembly fixes GE and Hotpoint refrigerators where frost is building up on the evaporator coils, the freezer is too warm, the fresh food section is warming up, or the refrigerator is running continuously without cooling properly. Single quartz tube heater, 120V / 725W. Assembly measures 12-1/8" L x 3-3/8" W x 2-1/8" H. Includes heater and bracket. Replaces WR51X10030, AP3183311, 914088, SH323, and more. Compatible with GE, Hotpoint, Kenmore, Haier, Americana, Monogram, and Café.

Installation Notes
⚠️ Unplug Refrigerator Before Starting — Wear Work Gloves Unplug the refrigerator before beginning. Remove all food and shelving from the freezer compartment. Remove the freezer bottom drawer and the back panel screws (typically 2 hex-head screws). Slide out the back panel to expose the evaporator coils and defrost heater assembly. If the coils are covered in frost or ice, use a hair dryer to melt the ice before removing the heater — do not chip or force the heater free while iced over, as the glass element is fragile and will break. Disconnect the heater wires from the wiring harness — note the orientation before disconnecting. Remove the 2 Phillips screws securing the heater bracket and lift the heater assembly out. Install the new WR51X10055 heater assembly in the same position, reconnect the wires, and reinstall the bracket screws. Reinstall the back panel, shelving, and food. Restore power and verify the defrost cycle operates normally. Wear work gloves throughout — the evaporator area has sharp edges. Tools needed: Phillips screwdriver, 1/4" nut driver, hair dryer (if coils are iced over), work gloves.
Frequently Asked Questions
What does the refrigerator defrost heater do?
Modern refrigerators use an automatic defrost system that periodically runs a defrost cycle — typically once or twice a day — to melt frost that accumulates on the evaporator coils during normal operation. The defrost heater is a glass quartz heating element that energizes during this cycle and melts the frost off the coils. This keeps the coils clear so air can flow freely through them to cool the refrigerator. When the heater fails, frost builds up unchecked on the coils over days or weeks — eventually blocking airflow completely and causing both compartments to warm up, even though the compressor is still running.
How do I know if my defrost heater has failed?
Remove the freezer back panel to expose the evaporator coils. If the coils are heavily coated in frost or solid ice — especially if both the freezer and refrigerator sections have been warming up — a failed defrost heater is the most likely cause. You can confirm with a multimeter: disconnect the heater and probe both wire ends. A working heater shows continuity (resistance between approximately 10–200 ohms at room temperature depending on wattage). No continuity confirms the heater element has burned out. Also visually inspect the glass tube — a burned, blackened, or broken tube is a clear sign of failure.
Should I also replace the defrost thermostat and temperature sensor?
Yes — since the freezer must be fully emptied and the back panel removed to replace the heater, it is highly recommended to also replace the defrost thermostat (WR50X10068) and temperature sensor (WR55X10025) at the same time. All three components form the defrost system and wear at similar rates. A failed thermostat or sensor can cause the heater to run too long or not at all — replacing all three in a single repair eliminates that risk and saves you from another complete freezer teardown in the near future.
My freezer is warming up but the compressor is running — is it the defrost heater?
It often is — but not always. A compressor that is running but not cooling can be caused by a failed defrost heater (frost blocking airflow), a faulty evaporator fan motor (air not circulating), a defrost thermostat or timer failure, or a sealed system problem (refrigerant leak or compressor issue). The easiest way to distinguish a defrost system failure from other causes is to open the freezer and check whether frost has built up on the back panel or coils. If yes, the defrost heater is the most likely culprit. If the coils are clear and the compressor is running, look at the evaporator fan or sealed system next.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured as a single quartz tube glass heater rated at 120V/725W to match the dimensions and performance of the original WR51X10055 defrost heater assembly.
