Why Car Thermostats Fail. Car thermostats fail when the valve of the thermostat fails to open, fails to close or gets stuck in a partially-open position. As the thermostat controls the flow of coolant to the engine, this can keep the car from warming up or cause it to overheat.

When low batteries eventually die, you'll see a black display screen, the thermostat will stop working and your heating or cooling units won't function. The heating and cooling system cannot respond to nonexistent temperature commands.

A blank or unlighted screen could indicate a thermostat failure. Check the batteries: Many modern thermostats rely on battery power to operate. If the screen is blank or unlighted, a battery change could solve the problem. Other thermostat malfunctions could also be the result of bad batteries.

What is a thermostat? ... We can tell just from its name that a thermostat is something that "keeps heat the same": when our home is too cold, the thermostat switches on the heating so things quickly warm up; once the temperature reaches the level we've set, the thermostat switches the heating off so we don't boil.
