Questions & Answers

For Whirlpool Refrigerator Defrost Timer (Part Number: OEM17955633)

1 Answer

Mike, In your case, the loose, black, timer motor wire should be attached to the #1 Terminal of the replacement timer. Then, the Orange wire attaches to terminal #1, Pink wire to terminal #2, White wire to terminal #3, And Red wire to terminal #4. When wired in this configuration, the timer will produce a defrost cycle every eight(8) hours of compressor run time and after the defrost bi metal thermostat closes. The other components of the defrost system is the heater WP2315530, which should have a resistance of 30 to 40 ohms, when tested with a multi meter, and the defrost thermostat WP4387503 which will have a "closed" circuit when cold or packed in ice, and an "open" circuit at room temperature.

Anselm,

You will want to make sure that the black lead wire that is on the timer goes to terminal labeled 2. If not then the timer will not advance during the normal operation.

Glenn for Model Number ET1CHMXKB07

My Whirlpool is leaking water into the refrigerator section when the drain hose freezes over. I replaced the Defrost Timer Kit part number 482493 and checked with your support team to make sure it was wired correctly( Thank You) I also replaced the Defrost Thermostat part number 1044241. The defrost heater is working because not only does it show continuity but it is hot to the touch. I clear the drain hose and everything is fine until it starts to freeze.To clear it I ran hot water through it followed by bleach, ran a wire through it, and dropped a pellet down it. The hose is clear as far as I can tell, but will start to freeze over in about 7 days and eventully become iced over to where it starts leaking. I am all out of ideas and would really appreciate some of your expert advice. The model number for the Whirlpool is ET1CHMXKB07 Thank You Glenn

Hello Glenn. It sounds like the drain pipe need to be blowed out using a turkey bastor and tube. Something keeps clogging the tube on the unit.

Hello Glenn,
Most of these will set up as a continuous run configuration so the black wire should be put on the terminal labeled as the number 1 terminal.

Matthew,

Based on your wiring diagram you would put the black lead over terminal labeled Number 2.
