Fridge not working on EHU (1 Viewer)

[faraway]

Morning all. I have a Thetford 3-way 'fridge, but one where you have to manually change the setting to EHU, battery or gas. All of a sudden, the 'fridge will not work on EHU. It works on gas (have not tried battery yet) and is running fine at the moment, just on gas. If I try to put it onto the EHU setting, the blue light just blinks. There is no problem with the EHU itself as everything else on EHU works. I can't find any useful information in the manual. Any suggestions as to what the cause and solution may be please?

Could be insufficient Amperage ?

Thanks. I'm an electrical ignoramus! It has worked well for the last year and the EHU hookup and use of other appliances has not really changed.

I had a similar problem in France, albeit a Dometic fridge. It was down to insufficient “power” at a particular site, fridge worked perfectly at next site.

I spent hours trying to sort it!

Are you plugged in to a known supply (ie are you at home?) if not I would suspect possibly low volts, we had similar in Spain some years back, EHU showed a connection and some things worked but we only had 130V do you carry a multi meter ? can you take a vent cover off which should then expose the input cables, maybe worth confirming the volts at fridge itself, if they are good I would fear the controller is faulty

Thanks. Yes, plugged in at home. I'll see if I can find a handy person to help me check with a multi meter, then I'll know how to use it for the next time

As you are at home probably the 230v element has blown.

Had a similar problem at honfluer and it was down either reversed polarity or insufficient power. Worked everywhere else .

Thetford Manuals Here :- https://www.thetford-europe.com/download-category/refrigerators/

There are 2 Heating elements 240V and 12V. the 240V one has likely failed?.

Check the supply first, there could be a Fuse too?.

Have you tried to switch it to Auto Setting should switch to EHU if on hook up.

@saint
I believe the OP stated that it is a manual change over system, not auto.

Re read and seen my mistake assumed it was an auto switchover sorry for any confusion

 

[JFD]

According to the installation manual, it has a 2A slow blow fuse in the 240v circuit, possibly in the little box at the back, where the mains cable is connected.

A useful tip to remember thankyou!
