Replacement for Atwood 36681 Propane/CO Detector
« on: October 13, 2026, 12:05:07 pm »
  I was "off line" on here for a while due to a password issue but Tina at the factory fixed everything..Thanks!

  The "end of life" beeping started and, since the Atwood 36681 is supposedly discontinued,  I purchased an R503 on Amazon which is supposed to have the same footprint. Before I install, does this seem a logical replacement?

Looking up the dimensions it appears to be a very close replacement and gets good reviews on Amazon.  I did find a place online that still has them in stock, albiet in white.

The Leakbee number was R503.
