DEFROST HEATER WP12729128

Hi Holly, thank you for your question. When you are having temperature problems in your appliance, there are a few parts that could cause the issue. You can use a multi meter to test most of the parts. Make sure you cut power to your appliance before doing any repairs or tests. First you should test your defrost thermostat. Place the thermostat in ice cold water for 2-3 minutes after removing it from your appliance. It should be reading 0 ohms to be working correctly. Another part to check would be your defrost heater. Remove it from the appliance. It should be reading anywhere between 0 - 50 ohms to be working. You could check your temperature sensor. To find the correct reading for this part you will have to refer to your tech sheet that comes with your appliance. You can usually find this tech sheet behind the bottom grille of your fridge on either the right or left side. These are the most common parts that cause this issue in your appliance. So it is suggested you check them first. Good luck with your repair.

Hi Jim, thank you for your question. Unfortunately we do not have any instructions for your appliance specifically. However we do have a video that shows how to install a defrost heater. You can view that here: https://www.youtube.com/watch?v=DTDJYrvrQjs. Because your appliance is a bottom freezer, you will have to remove everything from inside of your freezer to get to the back wall panel that hides your evaporator. The defrost heater is underneath the evaporator. Good luck with your repair.

Hi Shirley. Be sure the doors are closing and sealing fully. It is possible you may need a new gasket. Thank you for your question and good luck with your repair!

Hello Dave, Thank you for your question. Unfortunately I do not show our website suggests to use wpw103383615 in place of W10316760. Based upon reviewing the model I show that while this part may appear different than the original, Whirlpool is still suggesting it will fit. Have a great day!

Hi Kyle, Thank you for your question. To verify if the thermistor or sensor is causing the issue, you will need to test it with a multi-meter. Begin by unplugging your refrigerator, then remove the back panel of your refrigerator to locate the main control board. The thermistor will be connected to the main control board. Remove the thermistor from the appliance in order to test them. Before testing them, you will need to place the thermistor(s) in ice water for 5 minutes in order to bring the temperature to 32 degrees F. The thermistor will produce different readings at different temperatures, and the suggested ranges below only apply to thermistors at a temperature of 32 degrees F. With the probes on the terminals and your multi-meter set to Rx1, you should receive a reading of 16,600 ohms (+/- 5 percent). If you receive a reading outside this range, you will need a replacement temperature sensor or thermistor. There are 2 wire harnesses listed under your model number. The part numbers for them are PS11731432 and PS8260195. We hope this helps. Thank you and have a great day.

Hello Kevin, Thank you for the question. We suggest testing the Thermistor. 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 Caleb, Thank you for your inquiry. We have researched the model number you have provided and show that this model does not have a defrost timer, it is controlled by the electronic control board. The defrost thermostat is part of the evaporator fan motor. We hope this helps and if you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

Hello Juan, thank you for your question. The most common reason for frozen evaporator coils is insufficient airflow. This is commonly caused by a clogged or dirty air filter, backed-up drain clogs, low fan speed on evaporator fan PS11755853 , or a dirty evaporator coil PS11756717. We hope this helps.

Hello Steve, thank you for your question! Since you have already replaced the most of the common parts that can cause the issue, there are a few additional things you might want to consider. Make sure there are no obstructions blocking airflow around the evaporator coils. Poor airflow can lead to uneven cooling and frost buildup. Check the door gaskets for any leaks that might be allowing warm air to enter the freezer compartment. Even a small gap in the gasket can lead to frost buildup. Ensure that the refrigerator doors are properly aligned and sealing tightly when closed. Misaligned doors can also lead to warm air entering the freezer compartment. Clean the condenser coils to ensure efficient heat transfer. Dirty coils can cause the compressor to run longer, leading to excessive frost buildup. That the refrigerator and freezer temperatures are set correctly. Improper temperature settings can affect the performance of the defrost system. We hope this solves your problem!

Hi Luis, the thermostat sensor also controls the defrost cycle is part w10316760. Thank you for your question and good luck with your repair!
