The Defrost Heater and Bracket Assembly is an OEM replacement part for GE refrigerators. It is responsible for facilitating the defrosting process, which is essential for maintaining proper cooling and preventing excessive ice buildup within the freezer compartment.

Symptoms of a faulty Defrost Heater and Bracket Assembly include:

  • Excessive frost or ice buildup in the freezer compartment
  • Inefficient cooling or temperature fluctuations
  • Water leaks or puddles forming inside the freezer
  • Unusual noises or burning smells during the defrost cycle

Causes of a bad defrost heater and bracket assembly can include normal wear and tear over time, electrical malfunctions, or physical damage to the heating element or bracket.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore refrigerator models.

NOTE: For a 9" double glass tube heater use WR51X10101

For Ge Refrigerator Defrost Heater And Bracket Assembly (Part Number: OEM9549942)

1 Answer

Sen H. The only way that you would be able to replace the terminal would be to get a 1/8" female insulated connector to splice onto the existing wire.

Hello Jen. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Ron F for Model Number PSC23NSWASS

I have a GE SxS fridge (PSC23NSWASS) which despite numerous repairs(see below) continues to have a problem with defrosting. I am assuming this because there is frost and ice droplets forming on the evaporative panel and the freezer temp rose to 4 (set at 0) and the fridge rose to 38(set a 34). This is always the pattern, in which I do a repair and manually defrost the coils and then after around 4-6 days, the problem with frost and rising temps occurs again. Repairs: I have replaced both temp sensors (WR55X10025) in the freezer, the defrost thermostat (WR50X10069) and the main board(WR55X10942). I tested the defrost heater with a multi-meter at room temperature and it read zero. Questions: 1) How to I really test the defrost heater? 2) why after the main board replacement is both the fridge and freezer temps going to 2 degrees both above and below their set temps? The old board did not do this I 'believe'. Note: I did clean the condensor with a brush and electrical parts cleaner. 3) what else could be wrong with this unit?

Roberto, If the evaporator coils are impacted with ice you will want to do a continuity test on the defrost heater and thermostat. If either does not have continuity then it will need to be replaced. If both check ok then you will want to check the resistance of the defrost thermistor. If the thermistor checks ok then you would need a main control board. If the thermistor does not have proper reading then replace the thermistor. The thermistor resistance reading should be 42.5K ohm at 0 degrees. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Vjb for Model Number GSS25SGPA SS

New defrost heater burned, melted gasket on left side. I recently first replaced defrost thermostat and then after that the defrost heater that I realized was burned out by looking at the smoke stained heating tube and broken wire coil inside it. The new defrost heater WR51X10055 that I put in began to smoke and melt after 1 day. I'm not sure the part was genuine GE as it only cost $18 on-line. I will now replace with a genuine GE part but do you think there could be something other than defrost heater that is the problem?

1 Answer

Hello VJB, This sounds like a bad connection. You see, a point of high resistance, (loose connection), will build more resistance and cause more current flow. This produces heat and will burn out even a new component. When you replace the heater this time, make sure the connections on the spade connectors are tight and use either some grease or petroleum jelly on the connections to repel moisture, which will contribute to the situation.
