What Is Nordyne Furnace Pressure Switch?

A pressure switch is a safety device used in a furnace to monitor the pressure of the system. It is typically found beneath the main access panel of the furnace and is connected to the draft inducer or blower motor. Its purpose is to ensure that enough air is moving through the combustion chamber of your furnace, which helps prevent a dangerous buildup of carbon monoxide.

The pressure switch consists of two parts: a diaphragm and a switch. The diaphragm measures the air pressure inside the furnace, while the switch turns off power to the burner if the diaphragm detects too little or too much pressure. The pressure switch must be correctly calibrated for it to function properly.

Function of a Pressure Switch in a Furnace

The primary function of a pressure switch in a furnace is to detect when there’s too much or too little air moving through the combustion chamber.
