My thermostat seems to stop operating for a few minutes every time the furnace turns on. Thermostat service said everything is good on their end and it is probably due to a faulty transistor. He said that the thermostat must be getting a power surge when the furnace comes on. Is there any chance I can work on this myself? I feel like I'm setting myself up for a here's-your-sign moment, but I really do enjoy home improvement/repair and feel confident about doing most jobs once I've found good resources. OK, there it is. Let me have it.
