Lennox Furnace Error Code E269

E269 indicates an ignitor circuit fault on a Lennox furnace. The control board has detected a problem with either the hot surface ignitor itself or the circuitry that delivers power to it. Because the ignitor is required to safely light the burner, the furnace shuts down and displays this code rather than allowing an incomplete ignition attempt. Diagnosis follows the same procedure outlined for code E207.

Start by inspecting the hot surface ignitor for cracks or damage and test it with a multimeter for continuity. Next, check all wiring connectors between the control board and the ignitor for corrosion or loose connections. If both the ignitor and wiring test correctly, the control board's ignitor output circuit should be evaluated by a qualified technician. Replacing the faulty component, whether the ignitor or the board, will resolve the fault.

If only the hot surface ignitor needs replacement, repair costs typically range from around 80 to 200 dollars including parts and labor. If the control board's ignitor output circuit has failed and the board requires replacement, costs can range from 300 to 600 dollars or more depending on the board and labor rates in your area. Having a technician confirm the exact failed component before ordering parts will help avoid unnecessary expense.

Resetting the furnace by cycling the power may temporarily clear the code, but if the underlying ignitor or circuit fault is still present, the error will return quickly during the next ignition attempt. A reset is useful as a first step to confirm the fault is consistent, but it does not repair the failed component. Proper diagnosis and repair of the ignitor or wiring is required for a permanent fix.

The furnace is designed to shut down and display E269 precisely to prevent unsafe conditions. Without a functioning ignitor, the control board will not open the gas valve, so there is no risk of unburned gas accumulation from this specific fault. However, the furnace will not produce heat until the issue is resolved, which can be a concern in cold weather. Repairs should be completed promptly by a qualified technician.
