I bought a 2019 Keystone Bullet as NOS in 2020.
The Dometic refrigerator has only used it when propane was hooked up, even when plugged into shore power. I assumed it was running on electricity when it was plugged in. Never even bothered checking.
Then last fall, I ran out of propane --while plugged into power. And the fridge warmed up. Hmm...
Checking... yeah. I could NOT get it to work off of shore power. I checked the breakers... all good. No easy fix. I thought I'd dive into it when I had some time to go crazy with my multimeter, etc. Today was the day.
I took the panel off.
Do you see it?
A little closer...
Yes. I haven't tested my fix yet. But I have a high-level of confidence that it might work just fine, now.
