Heat Controller VMH18SC-1 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can reliably detect the flame upon ignition. As with most devices used for safety reason, if the sensor produces an error the gas valve is shut off and the system halts until that particular problem is fixed.
Chief elements of a laboring safety flame sensor
- System will kind of run on certain occasions when it thinks it should
- The heating system will not produce any heat when the thermostat kicks in
- The main type of gas has a tough time trying to ignite and the whole system shuts down
