Hotpoint temperature control problem
Model Number: CTX20GGB Brand:
More than 10 years
I've got this refrigerator in my basement, I'd say it's about 25 years old. A few weeks ago I noticed that it wasn't cooling very well (40°F on the thermometer). My first thought was that the coils must be dirty, so I tipped it back and gave the coils a good cleaning with a brush and my shop vac. It seemed to help, which surprised me, because they weren't that dirty. After a few days I noticed that the temperature was high again, so I took a look at the wiring diagram and decided the problem was either the defrost timer or the thermostat. I ordered replacements for both and swapped out the timer first. That seemed to work, but again after a few days the temperature was elevated. I then replaced the thermostat and nothing has really changed, Sometimes I check it and it's 28°F and other times it's 40°F. There was nothing in the freezer and the refrigerator has a 24 pack of Coke cans in it. I've now put a gallon of water in the freezer. I'm continuing to check it but the temperature swings don't really make any sense to me. Any suggestions will be appreciated.
