Questions & Answers

For Ge Refrigerator Defrost Timer (Part Number: OEM7906446)

1 Answer

Paul, On that style older refrigerator, you'll probably find the defrost timer located behind the kick plate, on the front of the refrigerator. It may also be located in the refrigerator compartment inside the control housing behind the light shield. But not in the freezer compartment, The cold, moisture or ice would affect the mechanism.

Hello Hector, The defrost timer WR9X482 is mounted in the rear of the unit. There will be a small hole with a small screw on either side where it is mounted. The hole is an access so the timer can be advanced into or out of defrost if needed.

Hello Bo. 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

Hello Karen. You will need to remove the grille from the bottom of the refrigerator and remove the screws securing the defrost timer. Then remove the timer and unplug the wires going to the timer. Now install the new timer WR9X482 in reverse order. Hope this helps.

Paul, Terminal #1 on the timer should have the neutral wire attached( usually white or orange), terminal #2 should have the wire to the defrost heater/ thermostat(usually blue) terminal #3 Should be the power into the timer from the cold control(usually gray or red) Terminal #4 should be the wire out to the compressor overload(usually red or black). Good Luck and Thanks
