International Comfort Products T8DNL075B12B1 Flame Sensor
A flame sensor is an important feature that senses the flame during the initial ignition of the furnace. As with most devices used for safety reason, if the sensor produces an error the entire HVAC system will stop until the problem is dealt with.
Hints of a poorly performing safety flame sensor
- The propane or natural gas cannot start an ignition sequence and shuts off
- The whole system will kind of run rarely when it thinks it should
- The gas furnace will not even begin to start and shows an error code on the board
