Mitsubishi MUZ-D30NA Flame Sensor
A flame sensor is a safety feature that can reliably detect the exact flame while the system is starting. Because of the safety issues involved, if the flame sensor gets set off the system remains completely shut down until the problem is dealt with.
Simple indications of a defective Mitsubishi flame sensor
- Your furnace cannot ramp up and spits out an error code on the main board
- The gas supplying the furnace has difficulty trying to ignite no matter what
- System will kind of run sporadically at midnight, but only after the new moon following the fourth Monday of the month
