I have a problem with this furnace.
It will run fine for a while, then out of the blue its starts to get cool in the house.
When i check the furnace the power is off. I turn the power switch off and back on then it will run fine and then out off the blue it will do it again. Any suggestions?

I'm going to move this to the heating section of the site.

When it does it, test transformer and input power wires to furnace for power.

Need 24VAC low voltage from transformer to t-stat to furnace.

Also need 120VAC line voltage to furnace through the breaker(s) and transformer.


Thanks,
Robert
