Ruud 47-25350-07 Auto Reset Limit Switch 160-180F 3in

Product Description

The RUUD 47-25350-07 is an auto-reset high-limit switch designed to protect gas furnaces from overheating conditions. It opens the control circuit when the sensed temperature reaches the upper threshold and automatically resets once the temperature drops back to a safe level. The switch features a 3-inch insert style mounting configuration, making it a direct-fit component in compatible furnace heat exchanger applications. Licensed HVAC technicians typically service and replace this component as part of routine furnace diagnostics or when an overheat fault is detected.

This limit switch is intended for use in residential and light commercial gas furnace applications where high-limit protection is required. The auto-reset function eliminates the need for manual intervention after a nuisance trip, provided the root cause of the overheating condition has been identified and corrected. The 3-inch insert design suits furnace vestibule panel installations where the sensor probe extends into the heat exchanger plenum or firebox area.

Key Features

• Auto-reset operation restores circuit continuity without manual reset after temperature normalizes
• Trip range of 160 to 180 degrees F provides defined high-limit protection
• 3-inch insert configuration for direct probe insertion into the heat exchanger or plenum
• OEM-style replacement for compatible RUUD gas furnace platforms
• Opens control circuit on high-limit event to shut down burner operation

Compatibility

Designed as an OEM-style replacement limit switch for RUUD residential gas furnaces requiring a 160 to 180 degrees F auto-reset, 3-inch insert style high-limit control.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off all electrical power to the furnace at the disconnect and turn off the gas supply before removing or installing any limit switch. Verify the replacement switch matches the original trip temperature rating and insert depth before reinstalling. After installation, cycle the system and confirm normal operation with no fault codes before returning the unit to service.
