Rheem-Ruud 42-106242-06 Pressure Switch Overview
The Rheem-Ruud 42-106242-06 is an OEM replacement pressure switch engineered to provide reliable draft and combustion safety monitoring in Rheem and Ruud heating systems. With dual pressure setpoints of -1.05″ W.C. and -0.93″ W.C., this switch accurately detects proper inducer operation and venting conditions before allowing the burner to ignite — protecting both the equipment and the occupants it serves.
Key Features
- OEM Rheem-Ruud replacement pressure switch — direct fit for compatible models
- Dual pressure setpoints: -1.05″ W.C. (open) / -0.93″ W.C. (close)
- Monitors inducer and draft pressure to ensure safe furnace operation
- Prevents burner ignition if proper venting pressure is not established
- Designed for long-term reliability in residential and light commercial heating applications
- Easy drop-in replacement to minimize downtime during service calls
Application
This pressure switch is a critical safety component in Rheem and Ruud gas furnaces. It continuously monitors the negative pressure generated by the draft inducer blower. If the pressure falls outside the specified range — indicating a blocked flue, failed inducer, or venting issue — the switch opens the control circuit and prevents ignition, safeguarding against incomplete combustion and potential carbon monoxide hazards.
