Carrier 38QRR024 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that will dependably sense the appropriate flame while the system is starting. Due to safety concerns, if the sensor get triggered everything comes to a halt until the main issue is remedied.
Indications the primary flame sensor will need replacing
- Your heating system is unwilling to start when you crank the thermostat up
- The LP or natural gas finds it impossible to ignite and the whole system shuts down
- The unit runs infrequently only after the second full moon of the month on a Tuesday
