Customer Questions and Answers for Damper Control Assembly by Whirlpool

Hello Bruce. WPW10503278 is the defrost timer for the model number you provided. It sounds like you may have a defrost problem with the unit. 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

Richard, With the fuses having been replaced and showing 88 on the display, try hitting cancel and try to clear. If this does not work then the issue would most likely be caused by a faulty control board.

Hello Richard, The manufacturer has made the thermistor available on this model only as part of the recessed lighting wiring harness W10296251.

Kim, The issue with the ice building up on the freezer floor would be caused by a clogged drain. You will want to pull the rear wall from the freezer and clean out the ice under the evaporator in the drain trough and flush with hot water. You will also want to install part number W10619951. For the issue of it getting too cold in the refrigerator section you will want to check to make sure that the damper is not stuck open.

Chris, With the freezer being the same temp as the refrigerator you will want to pull the rear cover in the freezer compartment and check for a full even frost pattern. If the frost pattern is only partial, such as only the top couple of rows of coils have frost or just a little frost on the line coming in, then there is a sealed system type of issue.

Hello Bobby. It sounds like you need to replace the control board on the unit.

Hello GERVAISE. Check and see if the fan motor is bad in the freezer or if the unit has a bad door seal and is letting in warm air in to the unit.

Mike, The defrost thermostat is part of the evaporator wire harness W11260592. You will need to order and replace the harness. There are no other "thermostats" in your refrigerator, your's has thermistors that work in sequence with the electronic control board.
