In part one of this two-part blog series, we went over some possible causes of situations where your home or building's thermostat goes blank and will not respond to commands. This can be enormously frustrating as a resident, but knowing why it's happening can go a long way to helping you remedy the issue, either on your own or with professional assistance.
At Airtime Heating & Cooling, we're happy to offer a wide variety of HVAC tune-up and repair services for all your components, including the all-important thermostat that controls operations of the entire system. What are some of the other possible reasons why your thermostat may have gone blank? Here are a few to keep in mind.
While it may seem obvious to most people, turning the thermostat on is the first step in making sure it works properly! If you've just moved into a new home or building, be sure to check that the thermostat is on and in the "Heat" or "Cool" mode, depending on the season.
The same goes for if you've been away from home for an extended period of time - when you return, be sure to turn the power back on at the breaker and check that everything is set properly on the thermostat itself before trying to use it.
In other cases, it won't be the thermostat itself that's been turned off, but another major component that connects to it - namely, the furnace or air conditioner. If your thermostat is blank but you know the power is on to both the thermostat and the HVAC unit, check to make sure that both units are switched on at their respective power switches.
Your thermostat connects to your HVAC system via low-voltage wiring, and if this wiring is damaged or frayed in any way, it can cause a blown fuse. If you suspect this may be the issue, the best course of action is to call in a professional technician who can properly inspect the wiring and make any necessary repairs or replacements.
Down similar lines, it's possible that the wires attached to the back of your thermostat have become disconnected. This can happen if the wires are old and brittle, or if they've been jostled or moved around too much (perhaps during a home renovation). Again, this is something that's best left to a professional to fix.
If you've begun to notice any issues with your thermostat, or any other component of your HVAC system, don't hesitate to reach out to the experts at Airtime Heating & Cooling. We'll be happy to come take a look and help you get your system back up and running as good as new!
