Why does thermostat Keep clicking on and off?
Your thermostat could be calling for hot or cold air and not getting it. The clicking is the relay trying again. Solution: Check your circuit breaker for a tripped circuit. You could have power to your thermostat—especially if it’s battery-powered—but not to your furnace or air conditioner.
Why does my heating thermostat keep clicking?
The click you hear from your thermostat is probably the electrical relay triggering the power to the furnace, air conditioner or heat pump. It is a normal sound. The sound should be soft and barely noticeable.
Can thermostat cause short cycling?
Your thermostat could also cause the HVAC system to cycle on and off rapidly, a process known as short cycling. Your furnace or central air conditioner spends a good amount of energy simply turning on and off, which is why you want yours to run for at least 15 minutes at a time before shutting off.
