Description
The Rheem-Ruud 42-106243-03 is an OEM replacement pressure switch engineered for precise draft and combustion safety monitoring in Rheem and Ruud furnace systems. Featuring dual set points of -0.75″ W.C. and -0.65″ W.C., this switch accurately monitors negative pressure generated by the inducer motor, ensuring the venting system is operating correctly before allowing ignition to proceed.
How It Works
The pressure switch is a critical safety component in induced-draft and condensing furnaces. It verifies that the draft inducer is running and that proper negative pressure is established in the flue system. If pressure falls outside the specified range, the switch interrupts the ignition sequence, protecting against incomplete combustion and unsafe flue gas conditions.
