RVs all come with a carbon monoxide detector, sometimes called a propane detector. Our coach is all-electric, so doesn’t have any propane on board, but such a detector is still useful.
These detectors are usually rated for 60 months from sale, which is five years. Our 2017 Tiffin Allegro Bus 40SP is six years old, so it wasn’t surprising that the detector in our bedroom recently started to give an end-of-life beep and light flash… at 2 in the morning, of course.
So it was time to replace it.
I ordered another model from Amazon, not doing a very good job of checking for suitability; I hadn’t noticed that the original unit is flush mounted, so a surface mount wouldn’t work (especially being a little smaller, so wouldn’t cover the hole in the wall).
So then I did what I probably should have done, and ordered a replacement of the same model as original from the Tiffin Parts Store, part number 5060082.
Here’s the old carbon monoxide detector:
Unscrewed from the wall:
It has the manufacture date stamped on the back:
The new detector from Tiffin:
It was manufactured in November:
Some tools to replace it; I got out both the wire caps and heat shrink connectors:
I decided to use the heat shrink connectors; here they are connected and crimped:
And using the heat gun to shrink them:
All done:
The light was blinking when I first connected it, which confused me as not one of the listed statuses, but it was just a startup sequence; after a few minutes it was a steady green. I pressed the button to test it, and all was well. Done!
