Has this ever happened to you? Your thermostat goes blank or the screen illuminates for a few moments before it fades to nothing? If so, don’t worry because you are not alone. The same thing happens to thousands of people, every year without fail and there are a number of sure-fire ways to fix the problem.
3 Reasons Your Thermostat Display is Not Working and How to Fix It
Your thermostat is one of the smallest devices in your home but it’s also one of the most important. Without it, you cannot turn your air conditioning system on or off, or set a schedule of heating and cooling in line with when you’re going to be at home. When it fails, it can feel a little overwhelming but fear not, here are three reasons and three ways to fix it.
1. The Breaker Tripped
Thermostats are typically connected to a home or business via the main electrical system, however, sometimes it or another device can cause the main breaker to trip. This is similar to, for example, what happens when a lighting strike happens to a nearby power station. To rectify this situation, simply open the breaker box and flip the switch back to the correct position. Finally, look at the thermostat screen to confirm that power has been restored.
2. The AC and Heating System Tripped a Safety Switch
If you inspected the main breaker and this wasn’t to blame for your thermostat display not working, then your next step should be to inspect your air conditioning system, in addition to your heating system — if this is separate. Occasionally, an underlying issue with your HVAC system can lead to a situation where the transformer no longer sends the voltage needed to power the thermostat.
With an air conditioning system, start by checking the safety switch, which is located in the drain pan. This switch detects problems such as high temperatures or excess moisture in your AC. It automatically sends a shutdown signal in these situations — in order to prevent damage, so if you notice that the sensor has been triggered, call your local HVAC professionals for an inspection.
3. The Thermostat Batteries Have Died and Need to be Replaced
If your thermostat is blank, one of the most common reasons for this is that the batteries have died. This is also one of the easiest problems to remedy, so simply swap out the batteries and see if your thermostat turns on. If it doesn’t and you’ve already completed steps one and two, it might be time to consider the worst-case scenario.
What’s the worst-case scenario?
If you have tried to fix your thermostat using the steps listed, and it still won’t turn on, then your thermostat is going bad and needs to be replaced with a new one. All thermostats are different, however, the average life of this device is approximately ten years. To confirm whether or not your thermostat needs to be replaced, give your local HVAC professionals a call.
