re: I need some home ac help

Probably contacts on outside unit. Mine did this and I just cut power to the outside unit soaked the contacts with contact cleaner and hit them with a plastic handled screwdriver and that fixed it. Be careful there because I think that capacitor can cause harm if you short it out. I am not an ac guy and use this advise at your own risk.

Also may check to make sure inside unit door is closed good at the blower. Mine comes open sometimes and a switch will shut the whole unit down.

Why in the hell are you idiots telling him his outside cap is bad? For frick sakes.
Either its the door switch or the blower motor relay or the cotrol board. Last resort is to see if you can get the squirrel cage blower started by hand. If so the blower capacitor is bad.

Its not going to be a fuse. The tstat is powered by the same supply that powers the air handler. If your compressor is running, you have power to the tstat, therefore your air handler has power as well.
Same thing with the panel. If your outside unit is running, then its not the switch on the access panel.
Same thing with the drip pan, if the outside compressor is running, then the system believes that it is up and running.
Your system thinks that everything is okay, obviously it is not. The blower in the air handler uses a capacitor just like the compressor outside. The capacitor stores extra energy that it then discharges when starting up the compressor, or the fan motor, etc.
If you want to test it, use a multimeter to find out what the capacitor is doing. This will be based upon the size of the capacitor, etc. I can't just tell you what the capacitor should read.
Turn the whole unit off for about 5 minutes. Then turn it on again. Does the blower motor sound like it is attempting to run. It will sound like it is trying to start turning, but then kick off. It may try this a couple of times and then just stop trying. This could be indicative that either the capacitor or the blower motor are bad. Again, use a multimeter to test them and see if they are working properly.

meauxjeaux2,
If the door switch is bad wouldn't the unit stop running the compressor?

No. Only the evaporation unkt would not work.

You need to get it fixed

Mine was running outside and not running inside. The pipes outside were froze up. I just turned the whole unit off and let it thaw out. This was on Sunday. Monday cranked it back on and still running and cooling today. Oh and on my digital thermostat it said unit is frozen.

Its likely the blower motor or the capacitor. If you have a volt mater with ohms. Check each wire coming off the motor to ground. If it reads bad motor. If capacitor is swollen then bad capacitor.

Throwing in the towel. Gotta be at work early. Repair guy has been summoned.

Because outside was buzzing and nothing working inside and banging on the contacts is what the interwebz said to try. :shrugs: that's my excuse for being an idiot. I don't know what the other folks got.

Turns out it was a bad control board he said he meant to replace a year ago when he serviced it. Cheap, easy fix
