Fridge / freezer Not working , Help please.

[Peskyrabbitt]

Thanks to everyone again who have gone out of there way to help us with our fridge issue, its much appreciated, We are leaving as is for the moment as it seems to be staying on ehu and will monitor the situation and hope it cools without faults, time will tell. Will post an update soon.
Who says motor homing is fun ? Trying to keep smiling but not easy. What annoys us the most is the dealer probably would have known about the faults we have found in our mh. ( not just fridge ) but it is what it is and we will soldier on as they say.

There is a shelf above the fridge which I have inspected for removing to allow me access but to remove the shelf the fridge first has to be removed.. have attached a picture.

That's only true if you want to remove the shelf more than once.

If you can access the top of the shelf, you could use a multitool to cut down through the supports, then fix it with blocks or wood trim from the top when you want to put it back. Or use new supports to take the weight, and fix it from the top to stop it moving. It might be worth it if you thought access to the control board would allow you to cure the problem.

Never thought of that, Quite a good idea, it may come to that thanks, would certainly make problem solving easier.

Hey there guy's..
Just going over what I need to do to remove the fridge and saw this ( picture attached ) it was in the off position, it states climate control switch. I'm assuming that this in the off position wouldn't have any effect on the workings of the fridge?

No picture, but if it is marked I + 0 (on + off) it is system to evaporate water droplets on the frame and will use 12v continuously if left on (according to the manual)
Is the fridge still working ?

If its the one in the picture attached its the freezer frame heater to stop condensation. Runs 12v continuously when switched on. Fine on EHU or with a good solar set up. Its independent from any other fridge/freezer functions so won't make a difference to your issue.

According to the wiring diagram there is a 3amp fuse on the fridge control board for 230v supply also another for the 12v system on the same board , are you able to check these if you can get to the control board ?

Hi all
Got into the control board ( will explain how later for reference to others having issues )
Fuses okay but what I did find is 2 unconnected wires & 2 spare pins .. (pictured) on the cover of the control board it states both pins mains, (pictured) but I'm wondering if this control board is an updated one and not the original as to why these have been not connected?

 

[Peskyrabbitt]

Hi, forgot to say fridge left on from yesterday afternoon on ehu, not cooling but no red error light.

On mine when I took it apart all wires were connected to the pins as per the cover diagram. On my new board all wires are connected to the pins as per the original board for it to function correctly. Makes me suspect that someone has had issues and disconnected the mains - Probably to force it to run on gas. If they were having the same issues as me with intermittent mains then that would be a fix to keep it running on another fuel source as the AES system will not see a mains connection with those two wires disconnected. I'm sure there may be another expert along but I am pretty sure that is the scenario. I can confirm that is an original PCB box as manufactured.

Thats what we are thinking also that previous owners had problems, do you know what wire goes where? ie blue and brown left or right or does it not matter if known?

It does matter! I’m out for a couple of hours but if you look at my thread showing photos of my new board fitted you can see the colour of the cables. I can access the folder on my laptop when I get back if you need it sent again.

Okay thanks will try and find it.
Found it thanks will go and plug in and see what happens !!! BOOF !!! fire extinguisher at hand

 

[GeoffnDee]

I wonder if it may be that the mains has been disconnected to avoid having to replace faulty 230v heaters ? (assuming that it would still try to switch sources with faulty heaters) This would not explain why it will not operate on gas even with 230v not connected.
Have you located and cleaned the multi 12v earthing point ? (black wires)

Good point. If that’s the sum of the problem easy fix provided you can work by touch. Seems like a lot of trouble to go to mind you. Must be easier to change the element through the vent. Last time I looked you can still buy the elements.

One possibility is that the mains relay switch failed, stuck closed, so the element was on all the time. Pulling the mains feed off would stop it, as a temporary fix. Something to watch out for.

Things just got worse, attached both blue and brown wires to control panel, switched on all okay for at least 5 minutes gently pushed the control panel back and put main cover back on and then whilst doing this there was a tiny bit off smoke and now no power, fuses look ok so now well and truly F------d

Bad times! Did the smoke come from the PCB?

Am not to sure as was putting outside grey cover control panel back on when it happened, there has to be another fuse somewhere am missing?

Fuses don't usually smoke, that's come from a component probably

Cant find anything that looks scored/burnt, would of thought that a fuse would of blown before a component?

 

[GeoffnDee]

Have you tripped a MCB on the van fuse board or elsewhere.

 

[autorouter]

Is that no mains power or no12V power? If 12V, is it just the fridge, or are other things off too?

 

[Peskyrabbitt]

Checked everywhere we know of and cant find any faults, we are seriously considering replacing the fridge, we could replace part after part and still not be any further forward with getting a working fridge, so may be best option. apart from carrying a mini fridge. and using existing fridge as storage.

 

[Graham Page]

I would take it apart again and look for any scorching or tracking in the embedded board (both sides). You could see where it overheated on my old one. There will be fuses somewhere in your van. They are all different. My hymer has all the fuses, electroblock and chargers under the front seats. Could be entirely different locations in yours and I only know where everything is on mine and that took some working out! You should also have a trip on the mains which is normally near where power enters the van.

No mains or 12v to the fridge and all 12v and mains elsewhere working as they should. Just seems to be the fridge. Have checked Fuses that I know of and all seem good.

Had it working on gas and recognising ehu after cleaning up some electrical/earth wires and connections, left it overnight (last night) but certainly not cooling on ehu as it was with gas which led me to believe that it's been the element at fault but before taking on the challenging job of taking the fridge out to do this searched to see if I could find an easier way to access this and that was when I gladly saw access to the black control board without pulling the fridge out, having access to this now I opened it to check the Fuses which were and still are intact, this was when I noticed that the control board had 2 pin plugs unused and after attaching these everything went extremely wrong! Now no power whatsoever going to the fridge.. all Fuses that I know of seem fine. If it's fried a component? Which one is it likely to be first?

 

[GeoffnDee]

Are the fuses on your Electroblock EBL unit all ok ? there should be two for the fridge 1 x 20 amp for supply and 1 x 2 x amp D+ signal the 20 amp one may be on the left marked Kuhlschrank (depending on your EBL model) If it is a 119 the connection block 2 seems to be the fridge supply one.

 

[Peskyrabbitt]

Everything working as it should apart from the fridge, no power on 12v or ehu anymore

 

[Peskyrabbitt]

We had a day off yesterday trying to resolve our fridge issue,( stressed out ) We have discussed our options and have decided to try and remove the fridge and see if we can find the fault, we think its a wiring issue as we have power going into the fridge after checking with a tester pen. if we cant find the fault, we are going to replace the fridge, due to age and parts availability, Fingers and toes crossed.
