Carrier 50JZ024300 Flame Sensor
The flame sensor is a safety device that will dependably sense the correct flame during ignition. Because of the safety issues involved, if the sensor goes off the gas valve is shut off and the system halts until the problem is repaired.
Signals your flame sensor is not going to last much longer
- System will work intermittently barely
- LP or natural gas has problems trying to ignite under any circumstance
- The furnace is unwilling to produce heat when you crank the thermostat up
