Friedrich MW12Y3FM Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that will sense the appropriate flame during ignition. Due to safety concerns, when the flame sensor gets triggered by something the system will halt until the problem is remedied and the system is reset.
Easy warnings your flame sensor needs replacing
- The type of gas you use cannot burn and some type of error flashes on the main board
- Your heating system cannot begin operations and shuts down
- The heating system will run rarely when it thinks it should
