Hi vic ,yes it is the model you describe,and wee have never had to use it on gas till now ,I never knew that the button pressed in till you said ,that would explain why I couldn't get it to light it is now been on for a couple of hours and is working fine, there is power both 12v and 240volt at the plugs at the rear of the fridge, but no heat or anything , does this mean it could be the heating element,many thanks.

Pleased that you have sorted it on gas!

The electric elements are thin metal tubes tucked in under the glasswool-insulated heating tube directly above the gas burner. You can normally access this easily after removing the external ventilation grills. If you can measure resistance, the 230v element should be something like 350 ohms. The 12v element will be just a few ohms, so will appear to be nearly a short circuit if OK.

The external grills have catches to release them. On mine each has two slide catches near the top which you slide towards the middle to release. There are variations, but they all work in a similar way.

Well, you say it was working OK on 230v after you replaced the element, but it is not now. You also say that it is still working OK on gas. It is reasonable to conclude therefore that your 230v element is not now providing enough heat.
The first thing we need to know is whether the element is actually consuming the power needed to produce the required heat (about 130w). The element itself could have an intermittent fault (unlikely); the thermostat could be faulty; or there could be a high resistance somewhere in the circuit which is either intermittent or has occurred since the fridge was last working OK on 230v.

The easiest way to analyse this is with a cheap plug-in power monitor if you have one.....you can just leave it for a few hours and see if the power consumed (Wh) is as you would expect. Alternatively you could monitor the current with a multimeter, but would need to keep a close eye on it to spot an intermittent problem.

If the element is in fact consuming the power you would expect, then it is probably not making good enough thermal contact with the refrigerant pipe in the heat stack. (I can't think why this might have changed since you replaced the element though)

Hi all, I'm installing a thetford N3112E fridge from scratch into my hobby caravan, have the display working on 12v, 240v mains connected but won't work on 240v, after setting up programme to run on 240v the display keeps flashing on and off, fridge runs on gas, the caravan is sited on a seasonal pitch and the fridge needs to be on mains only,,thanks in advance

Having looked up the user manual online.
www.thetford-europe.com/product/n3112-automatic/#

one of the fault indications is "All lights blinking" the instructions are

"Switch the refrigerator off and on again. If the problems still exists, contact a service centre."

The installation manual does state that the electronics requires a low power 12dc connection. So if you need to run it on 230V ac you must also have a 12V dc power supply operating.
