GE Refrigerator not Cooing
Model #PFS22SISBSS, this french door refrigerator apparently stopped cooling while the customer was asleep. Everything seemed fine the previous night, but when they were going along with their morning routine of making breakfast and lunches, the temperature didn’t seem to be as cold as usual. Prior to leaving for work, they set the temperature to a colder setting, but once back home, they noticed everything in the inside of the refrigerator was about the same temperature as the outside of the refrigerator.
The path for diagnosing a refrigerator that is not cooling really depends on whether or not the problem is with the sealed refrigerant system, or something else. Refrigerators, freezers, and air conditioners all use the flow of a refrigerant to move heat from one place to another. By removing heat from lets say the freezer section, what we get is cold. Simple enough to understand, but if this system were to fail say from a leak, well the cooling process comes to an abrupt halt.
Because the actual diagnosis of a sealed system requires specialized tools, and a very good understanding of the system, the average person should really leave these problems to the professionals. But in reality, most refrigerators that stop cooling do so because of many other things, some of which have nothing to do with the refrigeration system.
When I began looking at this refrigerator, the first thing I noticed was the compressor was not running. The compressor is the component that moves the refrigerant around the sealed system and without it, well no cooling is going to take place. The compressor can stop for several reasons, but the most basic is no power.
I started by taking voltage measurements at the compressor, and this is where I found there was no power to the compressor electrical terminals. The main board located on the back of these refrigerators is what provides the electricity to make this compressor operate so that was my next place to do my electrical checks. With the cover removed, I could not only see the problem, but the smell was unmistakable.
Two of the capacitors on this board had all but blown up, leaving the rest of the board just about worthless. I did some looking around for possible reasons, then remembered a bulletin mentioning problems with these two components. My next step was to install a new control board in place of the old one to get this refrigerator cooling again. Once everything was connected and the unit plugged back in, the compressor turned on as usual with all the other associated fans and sounds.
