Customer Question

My name is ***** *****. I just changed the batteries on my Honeywell 8320U thermostat. Now I can't get the heat to come on. Checked the breaker switches on the furnace and at the main breaker box for the heat pump. Display says "heat on" but the furnace never comes on. Then the display changes to "Aux Heat On" but still nothing comes on.
JA: Thanks. Can you give me any more details about your issue?

Hi i am dan. I can help you with this. Was it working before you replaced the batteries?
Customer: replied 10 months ago.
but there was an issue the week prior where the breaker for the heat pump was tripped. Unsure why. Anyway, later Friday, a buddy and me looked at the furnace. We pulled the panel off and found a blown fuse. We replaced the fuse and turned the 2 breakers on the furnace itself back on and fuse imediately blew again. We recreated the same issue with a second fuse. It seems to blow when the top most breaker of the 2 breakers is turned on. Wondering if the breaker is bad. I called a tech to come out and they're supposed to be here this morning.

Ok if the fuse is blowing it most likely has a short in the thermostat wiring
