The reason your thermostat might not be starting could be due to several factors, such as a tripped circuit breaker, dead batteries, a blown fuse, or even incorrect settings. First, check if your thermostat’s batteries need replacing. If the batteries are fine, ensure that your circuit breaker hasn’t tripped and that the fuse for your HVAC system is intact. If these components seem to be in order, review your thermostat settings to make sure they’re correctly configured for heating or cooling according to your needs.
