Furnace Question
My furnace work ok during the day but late at night after I'm in bed I'll wake up hearing the fan run and get up and no heat turn off and wait a few and turn back on and works. Don't know what's going...

Rule out the easy stuff first:
What is voltage at the furnace when this happens?
Remove the PC board connections, clean and verify they are tight.
THEN troubleshoot if problem persists.
