International Comfort Products GDL125N20A3 Flame Sensor
A flame sensor is an important feature that can reliably detect the exact flame while the system is starting. As expected, if the sensor generated a error the gas valve is shut off and the system halts until the main issue is remedied.
Indications to watch for in a failing furnace flame sensor
- Your furnace refuses to begin working when the thermostat kicks in
- The furnace kicks in occasionally at the stroke of midnight after the second full moon following the second Sunday of the month
- The LP or natural gas has difficulty trying to ignite no matter what
