Common Symptoms of a Failing Lennox 49M84 Flame Sensor
Whether you're troubleshooting a furnace in Calgary, Edmonton, Red Deer, Lethbridge, or Medicine Hat, Alberta, or servicing equipment throughout the Greater Toronto Area including Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Ajax, Whitby, and Oshawa, these are some of the most common symptoms of a faulty or contaminated flame sensor:
- Furnace lights but the burners shut off after a few seconds.
- Furnace repeatedly attempts to ignite before entering lockout.
- No heat even though the hot surface ignitor is glowing.
- Intermittent heating operation.
- Ignition lockout or flame failure fault codes.
- Burners cycle on and off unexpectedly.
- Furnace operates reliably only after the flame sensor has been cleaned.
- Carbon buildup or oxidation on the sensor causes a weak flame signal.
The Lennox 49M84 is a genuine OEM replacement designed to restore proper flame detection and dependable heating performance.
