Hello kids. Over the past 3 years my Dometic RM 2454 eyebrow board was responding to a few tricks to get the fridge started; see previous posts in this thread. First, hold the "On" switch in for a few seconds. When that gave no joy, pull the panel out and unplug, then replug the connector. Finally, pull the panel out and shim the connector with a strip of paper towel. Once it started it never crapped out. Yesterday, it refused to respond to any of these. BUT....... I found the eyebrow and power boards are now manufactured at Dinosaur Electronics. Here is a link from a vendor that carries them, for the eyebrow board. You can find the replacement power board (Black Box outside) on the site easily. https://www.rvshop.com/Eyebrow-Board-Replacement-2-WAY-3-WAY-Dinosaur-Electronics-DE-ADJ_p_79109.html The Black Box Dometic boards should have the part number on the front of the box, in the smallest imagineable font. Mine is part number 385071201, and RVSHOP carries a Dinosaur board to replace it. The eyebrow board will supposedly will work with the OEM power board. I will order both in a few weeks and re-post. Just spent $4000 on my Jeep and F-250, tight right now. Jim PS: I am quite happy with my Oliver, but I will NEVER buy another RV without ordering a full set of boards that are proven to work. This will be a non-negotiable. This way, companies like Dometic can't stick you with garbage that breaks, with no repair parts available, so then it's "Whoopsie Poopsie, $2500 for a new fridge install!"

Yep. My Dometic is dated 2017, and they are already out of boards for it. I just hope it's a "permanent" fix. Jim

Hello All, Have tested the fridge for about two weeks, 5 days on, 3 days off, 5 days on. Each time to start I pushed the "on" button in and held it until the relays outside clicked and the eyebrow board lit up properly indicating that it had selected the power source. On the first test I ran through all three power modes, the second test was with AC only. The fridge worked fine without shutting down. My conclusion is that it's not time to replace the fridge as long as I can get it to work reliably by holding the on/off switch in on the board until it starts. (I know, this could change tomorrow). I'll keep testing it before our trip in March. This seems to be a hack that can keep your fridge working for a while. It may simply be the on/off switch module. I removed the board from the fridge and tested continuity across the terminals, but there was none in either the off or on position. Don't know if this is a bug or a feature, it may need to be plugged in for this to happen, I don't know. I could wire a simple SPST switch to replace it and can solder fairly well but this seems to be a bit beyond that. Looked everywhere for the board, no joy. See above in the thread. Anyway, hope this thread gives someone a tip they can use. I'll eventually replace the fridge with a compressor unit but I don't think I need to do it just now. Jim

I wish press and release had worked. I've waited several minutes with no joy, then had to pry the board out, remove the pin connection, reconnect, and try again. Jim

Sprayed contact cleaner on switches, then blew out with canned air. Will reinstall and go through new startup procedure (hold until it lights up) and then let everyone know how long it stays on. Reinstalled. Held switch down until AC was automatically selected, then released it, so far, so good. I'll check on it daily and keep you guys posted. Jim

Thanks, that trick may be the way to go. Jim

Here is the back of the eyebrow board, rotated 90 degrees, focusing on the power switch. The rows you see L to R are actually vertically disposed. I am getting no continuity from any terminal on the left (top) to any terminal on the right (bottom) when the switch is on, yet the board will still work when plugged back in and the power switch held firmly. I am assuming that the two center solder connections (double lumps) should show continuity when on. Next step? Contact cleaner and compressed air.

Update: Power into the ignitor (outside) board is OK, all fuses there (3 of them) OK. Appears to be the on/off switch itself. Must be pushed in for a while, firmly, to hear a relay click outside, then inside board lights up. Will not stay "ON" reliably though. Next step: Pull inside board and clean contacts, re test. This image might be rotated, the black AC power cord is at bottom.

Thanks for the help! I have bookmarked the suggested thread for troubleshooting ideas. I am going to troubleshoot, then try to replace one board only, if I can find it, this week, then order the TruckFridge and go with the swap by the end of Jan if no joy. Don't want this dragging on and I never trusted absorption fridges anyway, too complicated, too many things that could go wrong.......like having your unit "buss out in flames" and burn to ashes....... Note to self.......Insist on buying a full set of boards (Water Heater, Furnace, Fridge) with any new RV purchase. If they can't get them in a timely manner, then ask, "Why are you trying to sell me an RV that's hard to get parts for? Perhaps we should consider this in the price...." Would save a lot of grief. Jim

Yes I will. Today I have to limb up some trees, tomorrow through Fri I will try to revive/find a new board, if it works I'll pass along the methods, if no joy then I'll replace the Dometic with a TruckFridge and pass those ideas along too. I should have bought a complete set of boards when I bought the Oliver. I'm the dumbest smart kid on the block. Jim

Fixed it.

Oh and yes Dometic gave me the part number......2932884030. Black. Nothing on Ebay or Dinosaur Boards and several other places so far. It may need both boards, and in any case they have to be compatible. That could be another issue.

Thank you all for the links and the prompt replies. I will do a few things to revive the board and will try to source one all next week before I pull the trigger. I'm not a boondocker, I use a Honda 3000 watt gen , so power would be no problem. I have the LE II, so I should be able to get things out in one piece. I will let you know how things go! Jim

Hello All, It's been a while since I used this forum, and opened a new account since I couldn't remember much about my old one! I have Hull 389, Nov 2018, and I suspect the eyebrow board on the Dometic RM 2454 is shot, and no eyebrow boards are available anywhere including Dinosaur Boards. I have bookmarked a few pages on this forum with tips on how to possibly revive the board and will try them next week. I seem to remember that someone swapped out their Dometic for a Truckfridge or something similar, and in case I can't get my Dometic going, I would be very appreciative of any tips or threads on how to pull it off. Thanks in advance, Jim
