OK, I'm a basic DIYer but know nothing about electrical or many appliances. But the prob I'm having is that my fuse in my furnace keeps blowin' out. Up until a few days ago my A/C and furnace worked great, both within a few years old. BUt all of a sudden neither turned on...no fan or hum from A/C unit...no blower or hum from furnace in the garage. I checked the A/C unit itself (looked inside) and everything seems normal. I check the furnace and everything looks the way it should, but when I check the 15 amp fuse it was blown. So I got a new one and replaced it, as soon as I turned on the thermostat to A/C to cool the house, my wife (who was looking at the fuse while I turned it on) saw it pop. So I tried again with another fuse....same thing, it popped. Like I said I don't know much about electrical, but I seem prety sure there must be a short or overload somewhere. I have no idea where to begin to check it out. Any help would be greatly thanked! Jason

I have a heating/cooling system with central air. The outside unit runs continously(both compressor & fan) regardless of how the thermostat inside is set. The heat/off/cool switch can be set to heat or off & the outside unit still runs. It doesn't matter where the thermostat temperature is set, the outside unit still runs. Even when the on off switch on the furnace is turned off the outside unit still runs. The only way to stop the outside unit running is to turn off its breaker. I have to keep the furnace fan switch turned on all the time or the lines and coil ice up. It is cooling just fine, just won't shut off. I know its probably some interconnect stuck in the run position. What is the problem here and is there anything I can check or do myself without calling a technician? Thanks, Ed
