Jay, You will need to rewire the new timer. You have a "version 2 " Cumulative compressor run application. For cumulative run timer push slotted loose timer
motor lead over & all the way down terminal number 2 with wire toward timer motor. Check and make sure the colored wires are attached to the proper terminals
1 – Black Wire 2 – Pink Wire 3 – Red Wire 4 – Orange Wire. When wired correctly to a refrigerator’s accumulated run clock, replacement timer will provide defrost every 8 hours of compressor run time after the bimetal closes. Defrost timer motors can and do get warm/hot, but the timer motor will advance and start the cooling mode in 20 to 30 minutes after the start of the defrost cycle.

George for Model Number ED22TEXHW01

Hi! I've replaced my defrost timer (483212) on my Whirlpool, and seems to work just fine! Put the jumper on the correct pin as with my old timer. My issue is that every few days, my coils freeze over and stop the fan from spinning that blows cool air into the fridge. When I advance the defrost timer using the dial, it clicks into the defrost mode, and I can see/feel heat from the heating element. I've also checked the defrost thermostat with a multimeter, and I am seeing continuity. I've also cleaned the coils underneath the fridge as well. However, it seems like my freezer is just getting too cold still or is not defrosting enough. I replaced the timer with the same timer as I had before, which worked great for 10 years, but now I'm seeing this issue with the coils not defrosting every few days now. Any ideas why this could be?

George,

This issue sounds likely that the timer received is sticking and not allowing the unit to into the defrost cycle and would need to replace the timer.

Bruce,

It sounds like you may have the black wire on the wrong terminal and should be on terminal number 1.
