AC on the brink
The outside condenser fan motor went out two years ago. It was a 1/8 HP and
I replaced it with a 1/10 HP motor that was available at the time. I since bought an exact copy of the 1/8 HP motor figuring it would be more efficient in the heat of summer. I planned on installing it in the next few days but tonight I noticed the compressor making a weird howling/hissing noise like it was giving up the freon ghost. It really freaked out the cat which is a twist since it's the cat that does the howling 'round here. After confirming that I was still getting cool air out of the ducts I went outside to check it out. The old 1/10 HP fan is running smoothly and the compressor seems to run okay but every so often it makes a crackling noise. No sign of freon leakage but an ominous hot electrical smell was observed. I'm wondering if the run/start cap is in the process of self destruction. There also seems to be an abundance of condensation moisture on and around the compressor and return coolant lines. I shut it down and plan to test the cap in the morning before running it anymore. Any suggestions or advice would be much appreciated. I am well versed in electrical design but do not have the equipment to recharge the freon if a compressor replacement is warranted. TIA, Tim |
