Thermostat not turning on heat? Let’s figure out the next step.

What is the thermostat doing?

FAQs

Why will my thermostat not turn on the heat?

Common causes include thermostat settings, dead batteries, tripped breakers, loose wiring, a control issue, or a problem with the furnace or heat pump.

What should I check first?

Check that the thermostat is set to heat, the temperature is set above room temperature, batteries are good if applicable, and the HVAC breaker is not tripped.

Can a thermostat be on but not start heat?

Yes. The display may work while the thermostat, wiring, controls, or heating equipment still has an issue.

Should I use emergency heat?

Emergency heat may help temporarily on a heat pump system, but it should not replace diagnosis if the heat pump is not working normally.

When should I call for heating repair?

Call if the thermostat is blank, unresponsive, will not start heat, the breaker trips, or the heating system does not respond after basic checks.
