Carrier 48JZ Flame Sensor
A flame sensor is one that can reliably detect the appropriate flame during the initial ignition of the furnace. Due to safety concerns, when the flame sensor is activated everything remains shut off until the problem is remedied and the system is reset.
Subtle hints the primary flame sensor is dying
- Any type of gas that has entered the furnace finds it impossible to ignite and shuts itself off
- Your gas furnace refuses to start operating at all
- The whole system will operate intermittently when it feels like it
