Flame Sensors
Flame sensors are safety devices used in gas furnaces, water heaters, boilers and HVAC systems. Their role is to detect the presence of a flame during equipment operation. They ensure burners have ignited properly. Flame sensors also send signals to control boards telling them to continue or shut off gas flow based on the detection of flames. This stops gas from leaking when there are no flames....Read more
Because the role of flame sensors is critical in preventing unsafe equipment or system operation, it is important to know the warning signs of malfunctioning flame sensors. Red flags include a furnace running for a short period of time then shutting off or the system cycling frequently. In this case, the system might ignite initially but then shut down if the sensor doesn’t detect the flame. If there is no heat or cold air blowing, it could mean the furnace isn’t staying on long enough to produce heat.
As with all HVAC system components, it is a necessity to include flame sensors in scheduled maintenance. Flame sensors need to be cleaned routinely to remove debris buildup. Make sure to securely reinstall these sensors to make sure there is proper flame contact.
