central a/c outside unit smoking


My a/c quit on me.. I changed the filters, and it was still blowing hot air. I checked the fuse in the attic. It was fine, I replaced it anyway. I flipped the breaker switch back on, and turned on the a/c. The condenser was humming, but the fan was not spinning. Then it started to smoke. It looked like the smoke was coming from the condenser unit..

So, my big question here, I suppose, is what the going rate is.. I think the a/c is 2.5 ton (I could be way off.. the last repair guy said I could have 10 ducts total coming off it.. I have 7) The a/c unit is only 2 maybe 2 1/2 years old.

Also, it's a Payne. And a royal one at that.

central a/c outside unit smoking


A couple ideas

Let it cool off (Condenser) and have someone turn it on again to see if the compressor starts. If it does turn it back off. I want to know what the amp draw is on the compressor and the pressures are.

If the compressor did a burn out the compressor is fried and it could have released the freon.

I understand that the fan is not spinning but before any repair is made need to know if the compressor in working

If you know the installer call them because there is a good chance the compressor will be under warranty for being 2 - 2 1/2 yrs old

Pardon my ignorance, but how do I discover the amp draw and the pressure?
And if freon has been released, would there be frost?

(thank you so much for the quick reply!)

You might be lucky and only have to replace a contactor or capacitor. Capacitors failures are very common and easy/relatively inexpensive to replace.

It will be chaeper for you to call a tech rather than buying a set of gauge and an amp meter.

It sounds like it's beyond the scope of DIY. Just get the original installer out to diagnose the system.

I'm betting capacitor failure vs compressor burnout!! (you should still have a parts warranty)

unfortunately, the realtor had it installed.. and all the work she had done was shoddy. She won't take my calls. And I was not even given a users manual, let alone warranty papers.

You don't need warranty papers to get parts. As long as you have a serial number that isn't past the warranty expiration date (date is encoded in serial number) you can still get the parts at no charge.

Thank you! The parts warranty is in effect until 2001. I was dreading this bill. Now I'm just mildly frightened. I'll post the problem and the costs in a few days.
