Defrost Heater

Hello Dan, Thank you for your inquiry. You can test the defrost heater, thermostat and the dispenser control board with a multimeter to see if they are functioning properly. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

Hi Joe, Thank you for your question. One thing that we would suggest checking is your defrost thermostat and your defrost heater. It sounds like you may be having issues with those parts. I hope that helps. Good luck with your repair.

Hello Craig, Thank you for the question. I suggest checking the fan motor in the freezer to see if it is working to circulate the air. PartSelect Number PS1526073. If the fan is working you can test the Defrost Thermostat PartSelect Number PS2378768. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Hello Bill, Thank you for the question. If both Defrost Heaters and Thermostats are good, you may have a Defrost Timer issues. The timer for this model is built into the control board so the board will need to be replaced. We hope this helps!

Hello Rahila, Thank you for the question. We suggest checking the Evaporator Fan Motor. The motor is located in the freezer and circulates the Cold air through the appliance and into the Fresh Food Section to keep it cool. You can also check the Air Damper to make sure it is opening and closing normally allowing the air to circulate. We hope this helps!

Hello Dorothy, thank you for contacting us. Based on the description that you have provided, we have concluded that your appliance is having a defrost issue. We would recommend checking the defrost thermostat, part number PS2378768, to fix the issue. We hope this sorts out your problem!

Hi Dorothy, thanks for reaching out! There are a couple of reasons you may be getting ice in the back of your refrigerator. If the drain (PS4144728 or PS4172177) under your evaporator coils is plugged, it will begin to freeze and you will see ice begin to build up in the bottom vents at the back of the fridge. If the evaporator fan blade or motor (PS4138377) gets iced up, air cannot be exchanged properly and the defrost heater (PS4140693) and evaporator coils might ice up around the middle and top vents. The panel will need to be removed and these parts can be inspected. If you find any of them to be faulty, Customer Service will be happy to help you order the parts. Hope this helps, good luck with this repair.

Hello Amy, thank you for inquiring. You will want to replace either this Defrost Heater part PS2369212 or the Temperature Sensor part PS1765215 for your model. Good luck with your repair!

Hello Shawn, Thank you for the question. This could indicate the appliance is stuck in Defrost Mode. We suggest testing the Defrost Heater. The correct resistance should be around 28 ohms of resistance. We hope this helps!

Hello Chris, Thank you for the question. Switch off the appliance, or pull out the electrical plug from the wall socket. Remove the food from the freezer and store it in a cool place. Leave the door open and protect the floor from the defrosting water. In order to speed up the defrosting process, place a pot of warm water in the freezer compartment. In addition, remove pieces of ice with an ice scraper before defrosting is complete. When defrosting is complete, dry the interior thoroughly. Switch on the appliance. Set the temperature control to the lowest temperature. Wait at least 3 hours before putting the food back into the freezer compartment. If the appliance dos not defrost on its own again, we suggest testing the Defrost Thermostat. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. If you need help placing an order, customer service is open 7 days a week.
