Ruud 42-105499-06 Pressure Switch

Product Description

The RUUD 42-105499-06 is a genuine OEM pressure switch designed for use in RUUD gas furnace systems. Pressure switches monitor the negative pressure created by the inducer motor during furnace operation and prevent the ignition sequence from proceeding if the flue or combustion air system is not functioning correctly. This part ships in original factory packaging and is not an aftermarket or generic replacement. Licensed HVAC technicians typically handle installation as part of furnace diagnostic and repair work.

This pressure switch is intended for residential gas furnace applications where a direct OEM replacement is required. It is suited for situations where the original switch has failed, is out of tolerance, or has been identified as the cause of a lockout condition. Because it is a genuine factory part, it matches the original fit, form, and function without modification.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with gas furnace controls and low-voltage wiring. Shut off power to the furnace at the disconnect or breaker before beginning any service work. Inspect the inducer hose port and tubing for blockage or cracks when replacing the pressure switch, as hose condition affects switch performance. Refer to local codes and the appliance service manual for proper procedure.
