Lennox 51M14 Furnace Flame Sensor

The Lennox 51M14 is an OEM flame sensor used in select Lennox gas furnaces.

The flame sensor detects burner flame during the heating cycle. If flame is not detected, the furnace control shuts down the gas valve as part of the furnace's safety sequence.

The 51M14 flame sensor is listed for Lennox furnace models including:

• 80MGF2-45A-6
• 80MGF2-45A-8
• 80MGF2-45A-10

Wolseley specifically lists these furnace models for the 51M14.

Common Symptoms of a Dirty or Failed Flame Sensor

• Furnace burners ignite and then shut off
• Furnace repeatedly attempts to ignite
• Furnace goes into ignition lockout
• Intermittent heating operation
• Furnace will not stay running
• Flame-sensing fault code

A dirty flame sensor can cause many of the same symptoms as a failed sensor, so the sensor should be properly diagnosed before replacement.
