hi,

I have a window mounted fridgid air unit. It has built in digital thermometer, and timers etc. One day after a brown out last summer, I went to turn the thing on, and it just blew air. I put the thermometer to the max, and still nothing but air. The condenser would not engage. Inspection of the electronics (visual only) showed no blackened parts.

I heard that brown outs blow compressors; is that true?
If that's true can I just swap out a compressor, or just junk the whole thing.

Thanks.

Cordially,
VitoVonAntwon

Brown-outs are hard on compressors, no question about that. Usually the internal overload will trip (smaller compressors like those found in refrigerators and window a/c's don't always have an internal overload but may have an external one).
It's also possible the electronic circuitry was damaged. Brown-outs sometimes occur with really big power surges capable of damaging computers and digital circuitry.
A technician would check the capacitor and for power at the compressor. If good, then a resistance check of both the run and start windings.

Changing out the compressor is not a diy job.

Ok,

I have to think whether I should bring it in or throw it out then.
I might take a volt meter and check the capacitor, is that on the main board, or on the condensor. I wonder if I can get a schematic of this thing from fridgid air?

Thanks.

Vito

may not hurt to have someone look at it.. it maybe a simple wire or something. if the compressor is fried, then yes it's cheaper to recycle it , and get a new one.
