Goodman GCH90703BX Flame Sensor
A flame sensor is one that senses the correct flame when the system starts. As with most devices used for safety reason, if the sensor produces an error everything comes to a halt until obstacle is corrected.
Some clues of a barely functioning primary flame sensor
- The propane or natural gas has a tough time trying to burn and closes the gas valve
- The furnace refuses to begin operations and will shut everything down
- HVAC system turns on rarely when it thinks it should
