With the recent heat spell, my Frigidaire window AC had been running a couple weeks. The other evening, I noticed that the compressor ~seemed~ to not be running nearly all the time like I'd expect. The next morning, it was getting warm in the house and the compressor was not coming on at all from what I could tell. Did not matter where the thermostat setting was at.
Based on some suggestions about a overtemp switch possibly being tripped if the coils were dirty, I pulled the covers on the unit after it had been shut off for a day and blew out any dirt and fuzz with compressed air. It was not real dirty. I checked the temp switch on the compressor housing and also the thermostat switch with a ohm-meter and they were both closed. Plugged the unit in and checked that the compressor was getting power with a voltmeter. It was, and I could feel it running too from the hum. No cold air though and tube coming from the expansion?? valve going to the inside coil was only slightly cold. Coils on the outside and the inside were both "room" temp and not one hot and other cold like it should be. I left it run for 5 min and the compressor housing seemed to be getting sorta hot.
What is the verdict here? Freon leak out? Is it fixeable? This unit is about 5yrs old and does not have a lot of hours on it since we only get a couple weeks a summer where its needed.
Thanks, Jeff
