Rheem 42-102069-04 Furnace Pressure Switch 0.55 Wc Single Port

Product Description

The RHEEM 42-102069-04 is a single-port pressure switch assembly designed for use in gas furnace systems. This switch monitors draft pressure during furnace operation, confirming that the inducer motor has established proper venting conditions before allowing the ignition sequence to proceed. Rated at 0.55 inches water column (WC), it provides a defined actuation point that protects against unsafe ignition under low-draft or blocked-flue conditions. Licensed HVAC technicians typically handle replacement of this component as part of a diagnostic repair when a furnace locks out on a pressure switch fault code.

This pressure switch assembly is used on the RHEEM R97V-USA gas furnace. It is suited to residential gas heating systems where induced-draft combustion is used. The single-port design connects to one pressure sensing hose from the inducer housing or collector box. This part is appropriate for technicians servicing RHEEM equipment in residential installations where the original switch has failed, is out of calibration, or has been identified as the cause of a no-heat lockout condition.

Compatibility

Designed for use on the RHEEM R97V-USA gas furnace as an OEM-style pressure switch assembly replacement.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off power to the furnace at the disconnect switch and set the thermostat to the off position before beginning any service work. Inspect the sensing hose and port for cracks or blockages before connecting the new switch, as a compromised hose can cause repeat failures. Work should comply with applicable local mechanical codes and the furnace manufacturer service documentation.
