Thermostat Sail Switch at Elijah Rubin blog

Thermostat Sail Switch. The thermostat sends an electrical signal to the furnace circuit board. If the temperature is too high, it will create an open circuit and shut down the furnace. When your furnace first receives the call for heat from your thermostat, it runs a quick check to make sure that the sail switch is open. The sail switch then sends power to the high limit temperature control. If your sail switch is closed, then your furnace circuit board gets confused. The signal passes through a relay and the blower motor starts. At full speed, it activates the sail switch confirming there is adequate airflow to exhaust fumes from the furnace. This could be a faulty switch. If the temperature in the combustion chamber rises above a safe. Here is the basic sequence of operations: The thermostat sends an electrical signal to the furnace circuit board. And here, i’m about to help you by identifying common sail switch. However, it could also be a blockage in the vents or tubing, which creates enough airflow to lift the sail switch, but creates backpressure and increased heat in the chamber. That thermo switch opens if the furnace gets too hot and shuts down the gas.
