Question about Frigidaire FAS155K1 Air Conditioner
Hi- Just the other day I noticed that the AC unit wasnt cooling. I shut it off and it continued to make a humming noise, although the fan did quit blowing. I removed the front air filter cover and saw that the cooling fins were completely frosted over. The only way to stop the humming sound was to unplug it. I let it sit a few days, unplugged. I plugged it back in and same thing...it hummed while the power was shut off. It did cool and blow properly until it once again frosted up the cooling fins. Any ideas would be greatly appreciated. Chris
The fan motor must have been stopping. If the fan stops, for sure the fins will freeze because there is no air flowing. common Fan motor problems defective bearing or bushing and starting condenser. If the bearing is defective, it will heat up and seize. Have the fan motor checked. The fact that the fins are freezing, means that there is enough freon and the compressor is working.
