If you find yourself fiddling with your digital thermostat and controls too often, or if it’s not responding at all, you might need to perform a reset. In today’s post, local HVAC company The Ice-Man shares a quick guide to resetting your digital thermostat.
Why You May Need to Reset Your Digital Thermostat
As with other electronic devices like smartphones and computers, your digital thermostat can benefit from a reset if it’s not working properly. There are times when thermostats can lose synchronization with the heating or cooling systems they control. This typically occurs during a sudden power outage. You may also need to reset your thermostat if it’s the first time you’re turning it on for the season, or after you’ve performed cleaning and/or maintenance.
Resetting Your Thermostat
Specific instructions vary by model, but most units can be reset by doing one or more of the following steps. Before starting the process, however, open one or more windows to allow for ventilation and maintain good indoor air quality if your HVAC system has to be turned off while you reset your digital thermostat.
Momentarily flip the battery — If your thermostat has a removable battery, remove it and install it backwards, reversing the plus and minus positions. Wait five seconds, then put it back in the right position. If the thermostat won’t turn on, it’s time to replace the battery.
Push the reset button — Some thermostats have a recessed button that needs to be pushed in and held for a few seconds. Always use a paperclip or the sim card ejector that came with your smartphone to do this, never a pen or sharp items like needles.
Flip the circuit breaker — Turn your thermostat off, then go to your home’s electrical panel, locate the circuit breaker for the HVAC system and flip it to the off position. Wait for about 30 seconds before flipping it back on. Turn your thermostat back on, set your desired temperature and check for airflow. Note that some HVAC systems may have the circuit breaker installed near the outdoor enclosure. If your digital thermostat still doesn’t respond, contact your HVAC technician for repairs.
