Carrier 25HPA448A0030010 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that can reliably detect the precise flame while the system is starting. Due to the overall safety issue, if the sensor get triggered the furnace will not start until the main issue is remedied.
What are the indications that my flame sensor is about to go out?
- The unit starts occasionally only after the second full moon of the month on a Tuesday
- The type of gas you use has a tough time trying to properly ignite and some type of error flashes on the main board
- The furnace is unwilling to work and will shut everything down
