A malfunctioning thermostat does not always need to be replaced. Common issues that occur with thermostats include dirt build-up, blown fuses, tripped circuit breakers and loose wiring. Dirt build-up often leads to a mismatched temperature setting which in turn can lead to overheating, over cooling, or a complete lack of hot or cold air.
