I remember the first time I had to reset my Lennox thermostat; it was during a particularly hot summer day when the AC suddenly stopped responding. Frustrated and in need of a quick solution, I decided to tackle the problem myself. What I thought would be a complex process turned out to be surprisingly simple and effective.
To reset a Lennox thermostat, start by locating the ‘Reset’ button, often found inside the front panel. Press and hold this button for a few seconds until the system reboots. Next, reprogram your settings as the reset might restore factory defaults. This simple process can resolve many thermostat issues.
It’s important to note that after resetting your Lennox thermostat, you may need to reconfigure your personal settings, including temperature preferences and schedules. If you have a programmable thermostat, you’ll need to set your daily or weekly program again. Remember, a reset is useful for solving minor glitches, but if problems persist, it may indicate a deeper issue with the thermostat or the HVAC system itself. Regular maintenance can help prevent these issues from occurring.
How to Reset Lennox Thermostat Network
Your Lennox Thermostat operates through a connection to your home network. If you are having issues with the connection, there could be a problem with your router strength or interference that is blocking your signal. The best way to solve this issue is to reset your Lennox Thermostat network.
To reset your Lennox Thermostat network, enter your ‘User Setting Selection Screen’ and press ‘Network Settings’. You can select your network, which will display the signal strength.

Turn the Wi-Fi on by pressing and sliding the ‘Off’ button from the left to right to ‘On’. Bring up the available networks and when you see yours, click ‘Connect’. You will then be prompted to enter your password information.
If your network does not automatically come up, you can manually input it into your Lennox Thermostat’s network settings. If this is the case, find the section marked “Enter New Network Information”, you will be prompted to enter the name of your network.
You’ll have to select if your network is a WEP, WPA, or WPA2. You’ll then be able to enter your network password, click connect, and your Lennox Thermostat should display as being connected.

How to Calibrate Lennox Thermostat
With older thermostats, you need to remove the front screen of the thermostat and access either the calibration screw or the mercury switch. This had to be done once yearly as regular maintenance. Once smart thermostats were introduced, this method has changed.
Your Lennox Thermostat comes pre-calibrated from the factory. It is designed to re-calibrate itself if needed. If you feel that your calibration is off, you can test it by putting a thermometer close to your Lennox Thermostat when it is running. If the temperature reads differently, you can run a reset.
