Earlier in the week the thermostat on one of my homes HVAC units started acting squirrelly. I walked into my living room Monday morning to find the room at a brisk 60 degrees, even though the thermostat was set to keep the room at 80. The thermostat thought the temperature in the room was 84, meaning the A/C had been running all night. I turned the A/C in that part of the house off and went to work. On my way home I stopped by the hardware store and picked up a new thermostat.
I didn't get around to replacing the thermostat until last night. Before disconnecting the old one I turned the system off at the unit then flipped the breakers in the central panel in the garage. Then I replaced the old thermostat with the new one, turned the breakers back on and turned the thermostat on...
...nothing. At first I thought maybe I had a bad connection in the new thermostat. So I shut everything down again, and checked the connections in the thermostat and turned everything on again. Still nothing. At this point I thought maybe the new thermostat I bought was faulty, so I set about uninstalling it and reinstalling the old one. So I shut everything down, disconnected the new one put the old one back. Turned everything on and...
...nothing. Neither thermostat indicates that their is a problem. After more sleuthing I found that the Furnace/Blower doesn't seem to have power even when the breakers for it are on. Normally their is a green flashing light on the front of the unit to indicate it is operational. Now their is no light, only a faint buzzing noise coming from the unit when it is supplied with power. I've tried turning off and on any breaker or switch I can find for the HVAC at this point, nothing seems to getting this thing going again. Is anyone aware of a reset switch on the system that I need to trip in order to get this thing going again? I'm about to throw in the towel and call in the professionals. I'd rather not have to do that if they are just going to show up, flip a switch then hand me a bill for a couple hundred bucks.
Any thoughts or suggestions would be appreciated.
