Diagnosing a power problem can be tricky if you're not an HVAC professional. You know there's something wrong, but you don't know what it is. Here are the most common reasons for thermostat issues:
Thermostats are sturdy and reliable devices that can last for many years. However, the older they get, the more likely they are to fail. Like your cellphone, your thermostat might simply need an upgrade.
After a busy heating or cooling season, HVAC systems, including thermostats, develop a grungy coating that's removed during heating and AC maintenance. Left unchecked, the gathering grime can cause high energy bills, poor performance, excess wear and tear, and premature system failure.
If you don't know how to program the thermostat, it won't work properly. Your technician can show you how to use the device to optimize performance and maximize energy efficiency.
Furnace Door Is Ajar
Some HVAC systems have a safety feature that automatically turns off the thermostat if the furnace door has been left open. Make sure the door is properly closed, and check to see if power has been restored.
Device Needs Batteries
A low-power warning from the thermostat means you need battery replacement. Without a steady power supply, the thermostat won't work. Replacing the dead batteries with new ones should correct the difficulty.
Safety Switch Got Tripped
Newer HVAC systems turn off automatically if they detect a safety issue. The condensate drain may be stopped up, or the drain pan may be full. Emptying the drain pan will often eliminate the problem.
Most thermostat issues are the product of old age and poor HVAC maintenance. Thermostat replacement is the only solution. Call an expert from One Hour Air Conditioning & Heating of Baton Rouge to learn more about our innovative HVAC products.
