Goodman GPH1336H21A Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that can sense the proper flame when igniting the system. For obvious reasons, if the flame sensor senses a problem the gas valve is shut off and the system halts for as long as the problem remains.
Key signs of an inadequate furnace flame sensor
- The LP or natural gas cannot burn and shuts off
- The heating system will start on certain occasions when it feels like it
- Your system is unable to even start and shuts down
