Lennox Furnace Flame Keeps Going Out at Milla Gadsdon blog

Lennox Furnace Flame Keeps Going Out. Learn how to troubleshoot and fix a furnace that keeps turning off due to thermostat, airflow, or control issues. The most common reasons for a lennox furnace not heating include problems with the igniter, flame sensor, flame rollout switch, and wrong thermostat settings. Find out how to change the thermostat setting, clean the flame sensor, clear the condensate drain, and more. Fixes include cleaning clogged filters, opening heat registers, fixing the thermostat, cleaning the flame sensor, and buying a smaller lennox furnace. A faulty thermocouple (a sensor that controls the gas valve and the ignition) could be the culprit if the pilot light keeps going out. Why the furnace flame goes out when blower comes on. Fixes include cleaning or replacing the igniter and flame sensor, checking the rollout switch, and changing the settings on your thermostat. Before doing any work on the furnace, make sure it is turned off and the gas valve is closed. If the flame sensor does not detect a flame, the control board will shut off voltage to the gas valve to prevent the furnace from heating. Your lennox furnace isn’t staying on because of insufficient airflow, thermostat issues, a dirty flame sensor, or the furnace is too large.
