Bimetal Defrost Thermostat

Hello Ken, thank you for your question. I would recommend testing the bimetal defrost as well as the defrost heater first. You will want to test the defrost thermostat and the defrost heater for continuity. If either does not have continuity then replace that part. If they both check good for continuity then replace the circuit board. To test the thermostat, set your multitester to the R X 1 ohms setting. Place each of the multitester's leads on a thermostat wire. When your thermostat is cold, it should produce a reading of zero on your multitester. If it is warm (anywhere from forty to ninety degrees Fahrenheit), then this test should produce a reading of infinity. If the results you receive from your test differ from the ones presented here, then you will need to replace your defrost thermostat. Before you can test your defrost heater, you have to remove it from your refrigerator. A defrost heater is connected by two wires, and the wires are connected with slip-on connectors. Firmly grasp these connectors and pull them off the terminals. You may need a pair of needle-nosed pliers to help you. Do not pull on the wires themselves. Use your multitester to test the heater for continuity. Set your multitester to the R X 1 scale. Place the tester's leads on one terminal each. This should produce a reading anywhere in between zero and infinity. If your multitester produces a reading of zero, or a reading of infinity, then your defrost heater should most definitely be replaced. There are many different kinds of elements, and so it is difficult to say what exactly the reading should be for your defrost heater. But it definitely should not be zero or infinity. If it is, replace the mechanism. I hope this helps!

Hi Robert, Thank you for your inquiry. There are some parts that you will need to check to see which one is causing the issue. You will need to check the electronic control board, the capacitor, the evaporator fan motor, the bimetal defrost thermostat, the damper control assembly and the condenser fan motor. I hope this helps. Thank you and have a great day!

Hi Paul, Thank you for your question. I think that you should first check your water inlet valve, see if it is sending too much water up to the ice maker. Thus over filling it and causing leaking that freezes and creates your ice build up. If that part is alright, I would suggest checking then your ice maker to see if it is working correctly. I hope that helps. Good luck with your repair.

Hello Matt, Thank you for the question. I suggest testing the Bimetal Defrost Thermostat, PartSelect Number PS11749348.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!

Hi Donna, thank you for reaching out. We have researched the model and would recommend checking the defrost thermostat, part number PS11749348. and the defrost heater, part number PS11738606. If these parts are working fine, we would suggest checking the electronic control board, part number PS11755733, for continuity using a multimeter. If you need help placing an order, customer service is open 7 days a week!

Hello Jimmy, thank you for contacting us. Based on the understanding of the issue, you may need to replace the compressor kit, part number PS2580803, to fix the issue. We hope this information helps!

Hello Conrad, Thank you for the question. Before starting the repair, you will need to unplug the appliance to cut power to the Fridge. To replace the Thermostat, you will need to remove the Freezer basket and the freezer door from the appliance. Once removed, you will then remove the icemaker from the side of the freezer. Next remove the screws securing the back wall to the appliance. In the center of the back wall there should be a vent. To remove the vent, there is a clip in the slot on the bottom that needs to be released to remove the cover, you can use a flat head screw driver. Once you remove the center cover, you will need to remove the cover on the right side and remove the thermistor from the cover. Once all of this is removed, you should be able to remove the back panel and access the bi-metal. Un clip the Thermostat and disconnect the wires and reverse the steps to install. We hope this helps!
