Furnace Repair Checklist

1. Check the Thermostat

To start, make sure your thermostat is signaling your furnace to ignite.

Digital Thermostat

Replace the batteries if the screen is blank. If the digital screen is jumbled, the thermostat may need to be replaced.

Make sure the switch is set to “heat” instead of “off” or “cool.”
