Regards Not tried that, charger is in Reich box, to isolate would have to pull a fuse, can't think other way, then we're not charging, or are looking for the fault, someone told me ,it's E relay problem in the box, Apuljack ruled that out Quote Link to comment Share on other sites More sharing options...

Labby Posted July 8 Share Posted July 8 (edited) Is the power supply point used when on EHU a different one to the one used with your extension lead ? Edited July 8 by Labby Quote Link to comment Share on other sites More sharing options...

Labby Posted July 8 Share Posted July 8 (edited) Have you carried out the error code check on the fridge display to confirm what fault is indicated .(when on EHU) Edited July 8 by Labby Quote Link to comment Share on other sites More sharing options...

onecal Posted July 8 Share Posted July 8 (edited) On 02/06/2024 at 09:06, rawhide said: As I said, the fridge has been tested off motorhome and is faultless, forget fault codes , element etc, the problem is somewhere in my motorhome, which baffles the engineers, starts and cools then flashing lights, after 18 minutes, my question, does anyone know what this is, some questions irrelevant in previous replies, but thanks anyway , regards Steve Strange as you quoted before, you did say forget the fault codes etc' are you now saying you actually have a fault code ? Is this fault with your old fridge or in fact the new fridge replacement ? Edited July 8 by onecal Quote Link to comment Share on other sites More sharing options...
Labby Posted July 8 Share Posted July 8 When you use the extension lead you are also by-passing the 230v supply to the PSU and the charger/12v habitation power supply , ). Could the Fridge control power board be receiving more than 12v (making it give out incorrect faults/flashing lights) when supplied through the charger/12v habitation electrics when on EHU. I expect you already know, but the error code 9 = AC heater on when it should be off, (according to the Thetford N4000 series trouble shooting guide) Quote Link to comment Share on other sites More sharing options...

Is this fault with your old fridge or in fact the new fridge replacement ? Was the same both fridges ,when flashing you press 3 buttons for the fault code,that story is to long Quote Link to comment Share on other sites More sharing options...
Keithl Posted July 8 Share Posted July 8 Can you take your MH to another location and try a totally different power supply? eg a relatives??? Quote Link to comment Share on other sites More sharing options...
Labby Posted July 8 Share Posted July 8 (edited) Could you put a meter across the fridge control panel/board input 12v supply on the rear of the fridge (black and purple cables) and see if the 12v supply voltage alters just before the fridge starts flashing , or when it is flashing Edited July 8 by Labby Quote Link to comment Share on other sites More sharing options...

Labby Posted July 9 Share Posted July 9 (edited) Are you sure there are two chargers or has the PSU intergrated one been replaced with an higher output external charger (with the original still in place but disconnected ). Is it Apuljack Electronics you are talking to about the problem ? Edited July 9 by Labby Quote Link to comment Share on other sites More sharing options...
