How Do I Tell if My Home Thermostat is Bad?

Answer

The most common signs of a bad or malfunctioning thermostat are lack of hot or cold air when the device is turned on and an unlit display light. Malfunctioning thermostats occur for a variety of reasons, and in many cases, troubleshooting the issue and following up with a simple fix can alleviate the problem.

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.

Blown fuses, loose wiring and tripped circuit breakers are common culprits when the furnace or air conditioning simply does not start, and a maladjusted anticipator is one of the top reasons for a thermostat repeatedly starting and stopping. If troubleshooting and repairing minor issues does not work, replacing the thermostat is the next step. Many households are updating their old thermostats with digital versions. Digital thermostats are very affordable and even offer a variety of convenient features that include digital temperature displays, warning lights and alarms, reminder messages and touch screen capabilities.
