If you have recently noticed that the screen on your thermostat has gone blank, then read ahead for a look at some of the most common causes of this issue and what you can do to fix them.
1. Dying Batteries
The first thing that homeowners should do is check the batteries. Even if there is still some power in the batteries, an older battery could be turning the system off and on. Depending on the type of thermostat that you have in your home and the batteries that are used, you might only need to replace them every four or five years. Others will need to change their batteries every few months.
2. A Tripped Breaker
Modern programmable thermostats, including those with wireless capabilities, are generally connected to the home’s main electrical system. Every homeowner should know where their electrical box is and how to turn the entire system off and on in the event of an emergency. Once the breaker is located, you can simply flip the switch back on and see if the screen turns on. If the screen is still blank, then it might be time to replace the thermostat entirely.
3. A Tripped Safety Switch
Most new furnaces and air conditioners have safety sensors that are wired to the thermostat. If the sensor detects problems such as high running temperatures or moisture, they will turn the system off. Families should immediately contact an HVAC specialist if the safety sensors have turned their furnace or air conditioner off. In many instances, these safety switches misread their surroundings and simply need to be reset.
