Mitsubishi MSZ-A17NA Flame Sensor
A flame sensor is one that can sense the correct flame during the initial ignition of the furnace. Due to the overall safety issue, if the sensor generated a error everything stops until the problem is remedied and the system is reset.
Elements of an ineffective safety flame sensor
- The heat system is unable to begin operations and shuts down
- The whole system will operate sporadically when the time is right
