International Comfort Products PGMD18G0405 Flame Sensor
The flame sensor is a device that can sense the flame during the initial ignition of the furnace. Due to safety concerns, when the flame sensor gets triggered by something everything remains shut off for as long as it takes to remedy the problem.
Cues of a poorly performing flame sensor
- Your gas furnace is unwilling to begin operations and shows an error code on the board
- The unit will work infrequently at midnight, but only after the new moon following the fourth Monday of the month
- The propane or natural gas refuses to try to ignite and the board throws an error
