I was working on a Kenmore Refrigderator 363.9731785
. The complaint was about a defrost problem. Cold freezer/warm fridge. I took a look at the evaporator, and it was frozen over. These are the following steps I took. Let's keep in mind, I've only been doing this for less than a year.
1. I metered the defrost timer. The only problem I thought I had was pin 1 and 3. Which read infinite. Of course later I found out about the capacitor between 1 and 3 and check the microfarad. So I guess I ate a timer.
2. Check the defrost thermostat. Cut the wires and metered it while the ice was still on it. It read open. So I replace it.
3. After i thawed out the evaporator. I metered the defrost heater. The reading started at 44ohms and counted down to 8ohms. Is the countdown normal? Is the defrost heater in ohm range?
4. Do to my lack of experience. I am having trouble determining if the defrost heater looks correct. Most heaters are either straight or contain in a glass shield. This heater rises in the middle like a inverted V and comes back down. I know this is an old refridge, but is this correct for this model? I can't locate a kenmore or a GE manual for this model to be sure. The image on sears part site is not of the original part.
5. Also I am stump on how remove the defrost heater. It's not screwed in or has holding pins. I see some type of tabs, but they don't seem like they release it.
I left this job not feeling confident at all. The feeling of leaving a bad defrost heater in the unit is nagging me bad. I feel a callback is in the making.
What is you honorable opinion?
