I'm also now thinking of replacing my Dometic NDR 1292 with the Samsung 197. Just went to check the coach for a trip tomorrow, and the fridge was off. Checked the breaker and fuses, all OK. Still have a few more things to check before I pronounce it DEAD. Will be 2nd time it's died in 3 years. Last time I still had my service contract, so all I paid was the $200 deductible.
It's dark and 31 degs, so I'll wait to tomorrow. If it's really dead, then we can still go, will use my 12 cuft garage fridge for the week-end.
If I get a Samsung 197 installed, I plan to install a small inverter, since I don't already have one. I think my current house batteries should be able to cover that inverter with the Samsung plugged into it. I'm just hoping I can get that Samsung in thru the door, and not have to take a windshield out.
