Carrier 58MSA10012120 Flame Sensor
The flame sensor is a device that will reliable sense the precise flame during the initial ignition of the furnace. As with most devices used for safety reason, if the sensor produces an error the system remains completely shut down until the problem is dealt with.
Key signs of an ineffective safety flame sensor
- The heat system cannot generate heat when the thermostat kicks in
- The gas will not even try to begin an ignition sequence and shuts itself off
- HVAC system will operate sometimes at midnight, but only after the new moon following the fourth Monday of the month
