International Comfort Products T9MPD100J20C1 Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that will consistently detect the correct flame in accordance with the initial ignition sequence. As with most safety features, if the flame sensor is triggered the entire HVAC system will stop until the problem is fixed.
Key clues of a weak safety flame sensor
- Your furnace cannot start and produces an error code on the circuit board
- LP or natural gas has problems trying to ignite and closes down
- The furnace will sometimes work occasionally only after the second full moon of the month on a Tuesday
