Description
 
The Suburban RV Furnace Limit Switch is designed to allow your SF model furnace to operate more efficiently and safely by protecting against over-heating.
  • Fits furnace models SF-20/20F (Above Serial No. 921403895).
  • Mounting holes distance: 1-5/8".
  • Limited 90 day warranty.
Note: Suburban furnaces after January 1990, have nine digits. The first 2 digits are year of manufacture. The next digits, indicate the week of the year and the remaining digits are serial numbers. Start with the year to determine whether your serial number is above or below, for example; a serial # beginning with 98 is going to be a lower serial number than one beginning with 01.

How can you tell if you possibly need to replace the RV furnace limit switch?
The limit switch will turn off the gas to your RV furnace if the temperature becomes top high. So one way to tell if the limit switch is bad, is if the furnace won't fire at all. Another good indicator is if the blower motor continuously runs and doesn't shut off, then this could be the issue.
