Description
The Rheem-Ruud 47-25349-01K is an OEM limit switch kit designed to provide dependable overheat protection for Rheem and Ruud heating systems. Limit switches are a critical safety component in any forced-air furnace — they monitor heat exchanger temperatures and shut down the burner if unsafe operating temperatures are detected, preventing equipment damage and protecting occupants from overheating hazards.
Using a genuine Rheem-Ruud replacement kit ensures proper fit, function, and compatibility with your existing system, eliminating the guesswork associated with aftermarket alternatives. This kit is the correct factory-specified solution for maintaining the safety and efficiency of your Rheem or Ruud furnace.

Why Replace Your Limit Switch?
A faulty or failed limit switch can cause a furnace to short-cycle, fail to ignite, or run continuously without proper shutoff — all of which compromise comfort, efficiency, and safety. Replacing a worn or defective limit switch with the correct OEM kit restores normal system operation and ensures the furnace’s built-in safety controls are functioning as designed.
