The pressure switch on a furnace is a sort of safety mechanism. Pressure switches sense negative pressure given off by the inducer motor and will shut down the furnace ignition if air pressures and venting are not well maintained. If your pressure switch is damaged or broken it will not send power to the inducer which means that the ignition processes will not begin. With the largest selection of parts online; 1st Source Servall has the OEM pressure switch replacement parts for your furnace model.
