My furnace will run all day, but at night it shut off. I put on a new thermostat thinking it would fix the problem. Yeah it will run during the day, but it kicks off at night. It is not a programable thermostat. any ideas?
thank you

If the furnace runs ok (during the day), try doing this at night.
locate where the wires connect to the thermostat on the wall. Assuming your wiring is correct, Jump the Red (R) 24V supply and the White (W) heating circuit.

What is the model and serial #s, are there any diagnostic codes in a window at the bottom of the furnace.
Be careful sometimes you don't get a second chance
