I've seen some other people asking about the refrigerator and I just went through that section in the owners manual and pulled out a bunch of sections and pasted them into 1 sheet that everyone should know. This is my 3rd Dometic and they are great refrigerators but they do have some places that we need to watch. First is the upper door latch, they can break and Little House Customs has plenty of extra and spare parts. I've copied part of their page here-
FRIDGE HINGE REPAIR/DAMAGE PREVENTION KIT
All too often we hear of the top hinge breaking on the 17" Dometic fridges. This is bad news when it happens because that top hinge is part of that quite expensive door! This stainless steel bracket is easy to install and will repair that broken hinge permanently or prevent it from happening on one that's not yet broken! The very thin profile is nearly invisible when installed. This is a must have for all 17' refrigerators.
FRIDGE SPILL CONTAINMENT TRAY
Okay, so if you’ve ever spilled milk in the bottom of your fridge, you know you want this and don’t need to read any further. If you haven’t, you still need it but are welcome to read on. This tray is sized to fit the very bottom of all 17” fridges. At 260.15625 cubic inches, it will handily contain an entire gallon of spilled milk while stealing almost zero space in the fridge. You did remember that there are 231 cubic inches in a gallon, right? OK, maybe not but I did... trust me.
FRIDGE BUTTON GUARD
Who hasn’t bumped the fridge control, switched to DC and run their battery down? This new version is made for us by Charlie Young. It's clear, fits the fridge well and doesn't require removal to operate the buttons. It attaches with clear VHB tape to the control panel. [end of LHC web page additions]
Back to the story -
The first thing we did with our last trailer was to call and make an appointment at LHC to have them put the additions on that we wanted. We had Larry put the "Damage Prevention Kit" on along with the "Fridge Button guard" and it really gave us a good piece of mind because we do take off through the woods with trailer in tow and park in some amazing places. Bumping the buttons will become a regular thing without the guard installed and I highly recommend it. The new metal door hinge replaces the plastic one that comes with the fridge and will save the door from needing to be replaced if the stock hinge does break. I added the containment tray to this article because I don't remember Karen having on in our fridge :) The only problem that we had with the fridge was caused by me not knowing the voltage limits of the control panel. Even though you're running on gas and thinking that as long as the battery is putting out, it will be ok, this fridge does have it's minimum voltage of 9.6VDC. It will work a few times if your lucky and your batteries drop below that, but if you continue thinking that it will keep it up... Unfortunately that won't happen. With our Casita, we only had one Battery and it worked pretty good most of the time with the one battery. Usually over night it would drop from a full charge of 13.8VDC down to usually 11VDC overnight and this is acceptable. But then I started getting cocky and kept taking it lower and eventually found out that her CPAP machine would run fine down to 9.5VDC before it's low battery cut off would kick in... You can see where I'm going here - because the fridge was on gas, I really wasn't worried about it. So one night when we were parked boondocking I noticed that the trailer hadn't charged back up while we were driving and found that I had not plugged it in all the way because a small piece of gravel had been knocked into the 7-pin connector. So we were now going to be starting off the night at only 11.5VDC even after running the generator. The CPAP kicked off and woke up Karen,and the voltage had dropped to 8.7VDC and that's when our refrigerator problem started. I could hear the pilot igniter probe clicking on and off, trying to relight the fridge but it wasn't working at all on propane but it worked fine on AC or DC... ANd that's what we used to get home along with our cool box that we keep in the back of the car.
An old friend of mine up here is a Mobile RV mechanic, so I gave him a call and he came right over. Then after pulling it apart and looking things over, he found that the main relay on the board wouldn't pull in, so the propane wasn't getting the signal to start. So I ordered the new board and that was that. The Moral of the story here is - Know the fridges limitations...
In the attachment, I've pulled out the basics and then some from the Dometic Owners Manual. It would be best for everyone to read the entire manual and then use this page if needed as a reference, but either way, if you read this, you will have a real good understanding of your Dometic Refrigerator.
Copy it, Paste it and Save it to your Oliver Maintenance Files :)
