International Comfort Products MF08B1500A1 Flame Sensor
A flame sensor is one that will dependably sense the flame during the initial ignition of the furnace. As with most safety features, if the sensor goes off the system remains completely shut down until the main issue is remedied.
Signs of a barely functioning safety flame sensor
- The furnace turns on sometimes barely
- LP or natural gas has problems trying to begin an ignition sequence under any circumstance
- Your heating system refuses to produce heat at all
