Description
The Rheem-Ruud 47-103670-04 is an OEM auto-reset low limit control designed to protect Rheem and Ruud heating systems from unsafe low-temperature operating conditions. With a close setpoint of 95°F and an open setpoint of 50°F, this limit switch automatically interrupts system operation when temperatures fall below the safe threshold and resets once conditions return to normal — eliminating the need for manual intervention.
