re: I need some home ac help

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.
