What Are Common Thermostat Problems That Cause It Not To Work?

Common thermostat problems include dead batteries, wrong mode or setpoint, tripped breakers, loose wiring, and failed sensors. Miscalibration, dirty components, or Wi‑Fi/programming errors can also cause no response or short cycling. In Carmel and Noblesville, our techs perform “Testing thermostats for accuracy and quick response,” tighten electrical connections, and explain the cause and repair options before work begins.

Quick checks:

• Replace batteries and confirm Heat/Cool and setpoint.
• Reset tripped breaker.
• Verify furnace switch is on.
• Reseat wiring or Wi‑Fi as applicable.
