Carrier 48XPN024040300 Flame Sensor
A flame sensor is a safety feature that will dependably sense the exact flame during the initial ignition of the furnace. Due to safety concerns, when the flame sensor is activated the gas valve is shut off and the system halts until the problem is fixed.
What red flags are there that my flame sensor is not working right?
- The unit will work on certain occasions when it wants to
- The type of gas you use refuses to try to begin igniting no matter what
- The furnace is unable to even start no matter what
