If the temperature gets too high within the furnace, the switch will open, causing the furnace to stop operating. The burners will shut down and the fan will continue to operate, cooling down the internal components of the furnace. When the furnace’s internal temperature decreases, the limit...
A two-stage gas furnace control system automatically shifts into a high fire only mode if, in two consecutive low fire heating cycles a limit switch is tripped to indicate that a gas valve is stuck in a high fire condition. In this way, continued operation is allowed to proceed in a ...
