Frigidaire CPA12EDU111 Flame Sensor
A flame sensor is only found on gas furnaces. It is a sensor that can sense the exact flame when the system starts. As expected, when the flame sensor is activated the whole HVAC system will remain stopped for as long as it takes to remedy the problem.
Subtle hints the primary flame sensor has very little life left
- System will run infrequently when the time is right
- The heat system refuses to produce heat and shuts down
- The gas that has entered the furnace will not properly ignite and the main board displays on error code
