I have a Day & Night furnace Model # 80CD-12A Series 152, It was working fine until we had a power outage. Now the pilot light has a flame, but when I turn the thermostat on the burners don't exnite. Do I need to turn the (furnance) gas totally off and restart the whole system? Is there a safety I'm over looking? Any help would be appreciated.

Thank You,

Mike

Start with the basics: check the power supply by switching the thermostat fan selector to on- does the blower run? No need to turn off gas & relight.

=I've checked the basics, blower fan works if I switch in on inside the unit. I have the old style thermostat. Glass tube with copper contacts and a small resistor soldered to 3 yellow wires.
