My heat is not working, and I checked all the breakers. Normally at
this point, I would give up and call a HVAC guru, but one thing caught
my attention. A few years back, our air-pump's compressor gave up the
ghost, but even then when I put it on emergency heat, the emergency
heat light turned on.

Any chance it is just the thermostat on this thing? I've been meaning
to swap it out for a digital anyway.
