The flame sensor is a safety feature that will sense the acceptable flame during ignition. Due to safety concerns, if the flame sensor gets set off the whole HVAC system will remain stopped until obstacle is corrected.
Some clues your flame sensor will die soon
- The propane or natural gas cannot properly ignite and shut down
- Your system is unwilling to begin operations and shows an error code on the board
- The whole system will sort of operate sometimes but only on the third Wednesday of on months beginning on Thursday
