There is ice build up on the back wall of the freezer. The fan is running. What do I need to test? Sensors? Heater, Defrost T-stat, Control board?
Thank you. I will be going to her house at lunchtime. Can you tell me how to remove the freezer door and/or drawer to access the back of the freezer?
Sounds good. Is there a diagnostic mode this can be placed into?
Thanks......I will let you know the results.
I found frost on the back wall of the freezer. I removed the back and there was blocks of ice at the top that restricted the fan also. I defrosted it all. Then I tested the defrost T-stat and found the fuse to be fine, but the sensor had no continuity.
I started it up again. The fan ran fine and the frost pattern on the evaporator looked good throughout the entire evaporator after about 10 minutes.
I am going to pick up the defrost T-stat tomorrow.
My only question that concerns me is........when I tested the sensor and it was open, could that be because the temp was high enough after defrosting it manually? How can I be sure.
I feel it is either the defrost T-stat or the control board. I can buy the T-stat for $9.50 at my parts store in Phoenix. The board is $136 I can buy it from Repair Clinic.com with a 365 day warranty installed or not.
What do you think?
That is what I thought also...Thanks
