Heat Controller HTV Flame Sensor
The flame sensor is an important safety feature that can reliably detect the proper flame when igniting the system. Because of the safety issues involved, if the sensor produces an error the gas valve is shut off and the system halts for as long as it takes to remedy the problem.
Symptoms of an ineffective flame sensor
- The heating system will sort of operate infrequently but only on the third Wednesday of on months beginning on Thursday
- Your gas furnace cannot produce any heat when the thermostat kicks in
- The gas entering the furnace has difficulty trying to properly ignite under any circumstance
