  • 【Part Number and Rating】 31091 high temperature limit switch for compatible RV furnace heater systems. Rated 190°F and normally closed, designed to open the heating circuit when the furnace reaches its limit temperature. Approx. 1.27 in bracket length, 0.62 in body width, 0.22 in mounting slot width, and 0.37 in terminal height.
  • 【Copper Temp Control】 Built with copper temperature-control components, a metal mounting plate, heat-resistant insulating body, bimetal disc, and spade terminals. Copper offers good thermal conductivity and electrical conductivity, helping the switch respond to heat changes more consistently while supporting stable contact performance in RV furnace service.
  • 【RV Furnace Fit】 Compatible with Atwood RV furnace systems, compatible with Hydro Flame RV furnace systems, and compatible with Dometic RV furnace systems using 31091 high-limit switch specifications. Fits AFLA, AFLD, AFMD, AFSAD, AFSD, AFSDA, DFLA, DFLD, DFMD, DFMDH, DFSAD, DFSD, and DFSDH furnace groups.
  • 【Model Coverage 1】 Compatible with AFLA35211/35221/35231/40211/40221/40231, AFLD35111/35121/35131/40111/40121/40131, AFSAD12111/12121/12131/12141, AFSDA12121, and AFSD12111/12121/12131/12141/16111/16121/16131/16141/20111/20121/20131/20141.
  • 【Model Coverage 2】 Also compatible with AFMD16111/16121/16131/16141/16151, AFMD20111/20121/20131/20141/20151, AFMD25111/25121/25131/25141/25151, AFMD30111/30121/30131/30141/30151, and AFMD35111/35121/35131/35141/35151 RV furnace models.
  • 【Function and Issues】 Designed for diagnosed 31091 limit switch service when an RV furnace short cycles, blows cool air, shuts the burner down early, has a blower that keeps running, or stops heating during camper, trailer, or motorhome use. Replacing a failed switch helps restore the furnace over-temperature response and helps prevent continued operation with an incorrect or nonresponsive limit switch.
