When the heater or air conditioner isn’t doing its job, it is often assumed that the HVAC unit is broken. Units do go out, but it could very well be the thermostat that is malfunctioning and preventing the system from working effectively. Consider these issues that can prevent a thermostat from working.
Batteries Need Replacing
For digital thermostats, batteries need to be replaced about once a year. This is something that can be easily forgotten about but should be the first thing that is checked when diagnosing a digital thermostat problem. A key sign that the batteries need replacing is that the unit doesn’t have power or is unresponsive when adjusting the temperature.
Some homes still have mechanical thermostats in place. A mechanical thermostat adjusts the temperature with a small lever. Over time, particles can build up inside the thermostat, which can cause the lever to not move properly. Simply taking off the cover and wiping away the dust will allow for the unit to function properly.
Surprisingly, the location of a thermostat can affect how it works. If it’s set too close to a heat source or placed on a wall that sits directly in the sunlight, the unit might malfunction by causing false readings.
Poor Connection or Frayed Wiring
A more complex issue that can occur is a poor connection or faulty wires that sends the wrong information to the HVAC system. Because working with wires can be dangerous, there is only so much a homeowner can do before needing a technician for their thermostat repair. A homeowner can try to assess the wiring and make sure that each wire is connected to the proper mount, but the average person may not have the appropriate knowledge to do so. If all wires appear to be in place but the thermostat is still not working properly, it’s time to call a professional so they can replace the faulty wires.
There are times when the thermostat simply cannot be fixed. All technology falters at one point or another, and after exhausting all options, an HVAC technician may suggest a new thermostat installation. For questions about heating or AC services, call the professionals at Champion AC & Plumbing.
