Haier HC30D2VAR Flame Sensor
The flame sensor is a safety feature that will sense the acceptable flame when the system starts. Due to safety concerns, if the sensor goes off the entire HVAC system will stop until that particular problem is fixed.
Signals of a defective primary flame sensor
- The type of gas you use will not even try to start an ignition sequence and the whole system shuts down
- The entire heating system kicks in rarely when the time is right
- Your system refuses to begin working no matter what
