I have a Lennox HS29-030-1p central air unit. Yesterday it stopped working. I went out and got two fuses from Home Depot. They said I had 20 amp fuses. The unit says it is a 30 amp unit and you can use 30 amp fuses as the max. It came back on with the 20's, but I am now getting no cold air. I tried resseting the breakers on my electrical panel (which was not tripped at all) but that didn't work either. My friend mentioned there might be a panel on the unit with a reset button?

But another thing I noticed, when I had the unit on and I was in the garage where my breaker panel is, my lights dimmed and I heard a buzz from the panel. That panel, the breakers and wiring were all replaced two years ago by Gold Medal. Do you think this is a problem with the unit or my electrical wiring?

Probably need a new start capacitor for the ac compressor.

Probally need a new start capacitor for the ac compressor.

Thank you for answering. Is it a costly repair? I just came off having a stroke two weeks ago and I can't do anything myself.
