Replacement for Atwood Model 100867


Active Member
I have a 2018 Cyclone 4005 which the propane detector has gone bad. I have searched the model number displayed on the top of the detector but find no matches. It says on it to replace 84 months after retail sale. Does anyone know if this model has been replaced? What model to replace it with? Thanks.

It appears that all Atwood propane detectors are unavailable. Maybe they went out of business. I ordered a Briidea detector from Amazon. It probably won't fit and I'll have to improvise.

Atwood was bought out by Dometic, so yes, Atwood products no longer exist. But if you search for Dometic propane detectors, there are 3 models of different sizes available.
