Carrier 38ESA036 Flame Sensor
The flame sensor is a regulatory sensor that will consistently detect the appropriate flame when the system starts. As with any other safety sensor, if the flame sensor is triggered the gas valve is shut off and the system halts until the main issue is remedied.
Signs of a barely functioning Carrier flame sensor
- Any type of gas that has entered the furnace has difficulty trying to start an ignition sequence and closes the gas valve
- Your gas furnace is unwilling to start operating when you crank the thermostat up
- HVAC system operates infrequently but only on the third Wednesday of on months beginning on Thursday
