Rheem-Ruud 47-25118-01 Manual Reset Limit Switch

The Rheem-Ruud 47-25118-01 is a manual reset limit switch designed as a safety control component for Rheem and Ruud heating systems. This limit switch monitors temperature within the heat exchanger or furnace cabinet and interrupts the heating circuit if a high-temperature condition is detected, protecting the system from overheating damage.

Unlike automatic reset limit switches, this manual reset design requires a technician to physically reset the switch after it trips — ensuring that the root cause of the overtemperature condition is identified and corrected before the unit is returned to service.

Key Features:

• OEM replacement part manufactured to Rheem-Ruud specifications
• Manual reset mechanism requires technician intervention after trip event
• Protects heat exchanger and furnace components from overheating
• Direct drop-in replacement for worn or failed original switch
• Compatible with select Rheem and Ruud gas furnaces and air handlers

This limit switch is a critical safety device in residential and light commercial HVAC equipment. Replacement with the correct OEM part number 47-25118-01 ensures proper trip temperature, mounting configuration, and terminal compatibility for reliable operation.
