• May 07, 2020 · Look for a raised button or switch to the right of your furnace ignition control box (or “Limit Control” switch). Press and release the limit control switch to reset your Lennox furnace. Follow these instructions in reverse to replace the control access panel.
The switch activates with air force pushing a plunger in the mechanism, which closes the circuit. If your Lennox does not activate normally during the ignition sequence, try running a quick bypass of the pressure switch to determine if it is the problem. Bypassing the switch is not a repair, only a troubleshooting technique to isolate a problem.
