Carrier 42C Flame Sensor
A flame sensor is a regulatory sensor that will dependably sense the flame when igniting the system. As you could guess, if the flame sensor senses a problem the gas valve is shut off and the system halts until the problem is repaired.
Important clues of a deteriorating primary flame sensor
- The whole system will kind of run on certain occasions but only on the third Wednesday of on months beginning on Thursday
- Your
system cannot even begin to start when the control board tells it to - LP or natural gas refuses to burn and the whole system shuts down
