Lost Power to Refrig

It seems that I do not have power to the AE control panel on my Dometic RM3804. The AS is currently at our camping spot and I came home to pick up volt meter to see if I can troubleshot the problem. My refer is plugged into an outlet located behind the refer, I'm hoping to start there and trace where the power ends. Any and all suggestions welcomed.

Thanks

Bill

that breaker might be on a gfci. try resetting (full off then on) the 120 volt breakers. with all the rain we've had, dampness might have tripped the breaker.

On most 2-way fridges the control panel is 12v not 120V.

I agree with Ricky.... First check to make sure the GFCI has not tripped...the 110 plug at the back of our frig is on the same circuit. On our rig, you have to switch the breaker (in the fuse panel) all the way off and then back on to reset (you can't do it at the outlet).

Just arrived home with the AS. All breakers looked good (not tripped) but I didn't't cycle the GFI. I checked the fuse next to the fan and it was OK.Right now a cup of coffee is the priority after that it's still early so I'll plug her in and see what I can find.

Thanks for the pointers. There were 3 fuses @5amp and one was blown. Never knew they were even there. I had every amp but 5. Look like standard automotive fuses. Off to find a box of fuses and leave the remainder in the Refrig compartment.

Just blew two fuses. We did have a lot of rain and the condensate hose runs to a evaporate box and that was full of water and I noticed a little on the floor of the compartment. Just started raining so I closed up everything and will try and dry out compartment with a hair dryer.

Dried out the access area. All fuses are good. I have 120V coming into the terminal block and 12VDC feeding a different block. I still have no power to upper control board (no indicator lights) and no power to various 12VDC circuits. I'm thinking the lower board is shot as that feeds the upper control circuit board. Well, as Luck would have it I found a box of electrical parts for a RM3804 on the forum's classified. Just waiting on where to send the dough, the seller is working up shipping costs. I replaced the ammonia coil in 2009 and now with these parts I'll have just about everything else.

There are 3- 5amp fuses on the board and 2 buss fuses and all are good. I have 12V and 120V going to their respective inputs but when I check for power at various 12V points noted on the diagram I have none and no power to the controls.

Sounds like your board went south.I switched to a Dinosaur brand as the are much more reliable than the standard oem board and more durable..

I'm thinking it's the board also. When I pull it off I'll be able to visual check out the back of the board for any shorts. Can't wait until I get the parts that I found on the forums classifieds.
