What the technician typically checks

A technician typically checks power, batteries, wiring and the C (common) wire, thermostat placement, compatibility with the heating and cooling equipment, and the system settings such as heat pump or auxiliary heat.

Before you call

Replace batteries if the thermostat uses them, check the breaker and furnace switch, and photograph the existing wiring before removing an old thermostat.

Questions

Why is my thermostat blank?

Dead batteries, a tripped breaker, a furnace door switch, a blown control fuse or a missing common wire are common causes.

Will a smart thermostat work with my system?

Many will, but compatibility depends on wiring and equipment type, such as heat pumps or multi-stage systems.

Where should a thermostat be placed?

On an interior wall away from direct sun, drafts, vents and heat sources, so it reads typical room temperature.
