International Comfort Products PGMD42G0604 Flame Sensor
A flame sensor is only used on furnaces that burn gas and is one that can sense the flame during the initial ignition of the furnace. As expected, if the sensor goes off the whole system stops until the problem is remedied and the system is reset.
Main clues your furnace flame sensor should need replacing
- The unit operates sporadically at the stroke of midnight after the second full moon following the second Sunday of the month
- LP or natural gas has a tough time trying to ignite and the whole system shuts down
- Your system refuses to work at all
