The answer to 'my thermostat keeps shutting off' is that there are several common causes, including a faulty thermostat, issues with the HVAC system, or problems with the home's electrical system. This can lead to symptoms like the thermostat not maintaining the desired temperature or turning off unexpectedly.
Some common causes include a broken thermostat, a problem with the HVAC system's electrical components, issues with the home's wiring, or a power supply problem. In many cases, the solution may be as simple as replacing the thermostat batteries or checking for tripped circuit breakers.
