Error code 35 on a Lennox thermostat refers to a “Limit Switch Fault” failure. This is when the limit switch becomes stuck in the up position.
If you have this error code and cannot reset it, it’s an issue with the limit switch. Here are some troubleshooting steps to take for this error:
– First, check that your limit switch is set to “off.” If it’s on, turn it off and then back on again. It should start working again after its been turned off for 24 hours.
