Thread: I hate electricity

Mike, look in the ac/heater closet. There should be a 110 circuit, unplug it. Remove the cover and find the transformer. There should be 2 wires screwed to it. Remove the wires, remember what color goes where. Plug the unit back in. With a multi meter set on 50 DCV touch both screws on the transformer with the test probes. One way the needle will shoot past zero, reverse the probes, the needle will show some voltage. You're trying to measure 12 volt on a 50 volt scale. If you have no reading the transformer is bad. Mostly caused by one of the T-stat wires outside has gone to ground.
I ran mine through a piece of garden hose so critters couldn't chew it and weed eaters wouldn't tear it up.
