While thermostats tend to be one of the most reliable parts of your heating and cooling system, they will wear out over time. It is important to monitor potential problems before they arise; the worst time to discover a thermostat has broken is when the temperature is rising or falling, and the HVAC system will not turn on. Pay attention to these signs to determine if your home thermostat has gone bad.
1. No Display Lighting
Most electronic thermostats have a back-lit LED display. If this display no longer lights up, or the screen seems blurry, it can be indicative that the overall thermostat has gone bad. However, it could also be a simple wiring issue or the thermostat may just need new batteries. Try replacing the batteries first and see if that helps. If the thermostat still isn’t lighting up, contact an HVAC technician to determine the cause.

2. Thermostat Not Responding to Temperature Changes
One of the most common tests for homeowners to check if their thermostat has gone bad is to set the temperature five degrees higher or five degrees lower than normal. If the system does not activate within a few seconds to compensate for the change, the thermostat may not register the temperature in the room. This can happen if the thermometer misreads the temperature of the air, but it can also be the result of improper thermostat settings.
3. No Air Is Flowing
The surest sign of a malfunctioning thermostat is the increase in temperature in a home during the summer months or the decrease in the winter months. If the temperature inside your home reflects the temperature of the air outside, it is because the thermostat is either off or not responding to input.
