Attempting to turn on your HVAC system by the thermostat and getting no response gives you an immediate sense of doom that something serious is wrong with your heating and air conditioning unit. Thankfully, it is usually a problem with the thermostat. Below are a few signs to look for to help determine the problem.
Thermostat Refuses to Turn “On”
A wall-mounted thermostat for your HVAC system powers in one of two ways. Thermostats are connected to power wires, or battery operated. Make sure that the source of power is intact. You do not want to pay a service fee to have a technician come out and find that the problem is a loose wire or bad batteries. If it is receiving power and still not turning “on,” it is a failed thermostat that requires replacement.
Thermostat Is Unresponsive to Changes
If your thermostat refuses to changes modes, is unresponsive to reducing or increasing temperature setting, or in any other way does not respond to a change, it will need servicing or replacement. You can attempt a reset of the thermostat if offered in the instructions for your device, but many do not have that option.
Rapid and Short-Cycling
When the heat or air turn on for short periods of time and make little or no change to the environment, it could signal a problem with the thermostatic control. Rapid and short-cycling are prominent signs that the thermostat is defective. Have a service technician check the thermostat and recommend repairs or replacement.
Consistently Loses Programmed Settings
One convenience with modern thermostats for HVAC units is the ability to program your settings in advance digitally. You can completely control the temperature comfort of your home based on your schedule. If the thermostat keeps clearing the programmed information, not only is it aggravating but a sign it is going bad.
