My dad has a chescold explorer 3 way fridge (green one) it has worked very well on gas and 240v (dont use 12v at all) but now its only getting cool not fully cold? The is only a slight build up of ice on one corner of the element, before the whole element pretty much had a built up of ice.. we have turned it upside down cleaned out the flue and the gas burner and it is completely level. Not sure if its the thermostat or what? Its not leaking any refrigerant and the flame is ok. Any ideas? Also have a old chescold mark 2 ( brown one ) that will not stay lit on gas. The flame works only when you hold down the "purge button" but as soon as you let it go the flame goes out, even after holding it for more than 2 minutes. Any ideas? Thanks

Your second problem, Scott, is a buggered thermocoupling. That's the thingy that sits in the flame, to act as a safety feature in case the flame goes out. Probably get one from dealer or one of the camping store?

Thanks Bob Y i had a feeling thats what the problem was with that one. Any idea why the green one is only getting cool not cold? Thanks

Scott,
Many years ago I bought a Chescold and it worked for a while but the tubular screen ( in the large tube at rear ) which separates the gas bubbles, became loose and rattled around. It almost stopped all cooling action. It must be a fairly common fault because my second Chescold did the same thing. Both travelled in comfort and not tossed around to cause internal damage. Having the gas option is handy though.

RMD thanks for your reply, but what is this tubular screen you speak of? Is it inside the refrigerant tube? Cheers

Sounds to me as if the refrigerant unit needs regassing. You probably have a slight leak. It is now decision time - do I re-gas or replace it?

The Chescold and many other similar types have Ammonia liquid inside them. If it leaks you will smell it soon enough. The heaters system separates the liquid into gas and liquid and it has to recombine through the fine screens which come loose. Nof fix, just replace.
Maybe you can fix them but it requires specialist equipment to hande the ammonia factor.
No re gassing is possible. They don't use that concept.

Thanks Erad, im not so sure it is because we can't smell anything or see any areas of white residue, also we can still hear it bubbling around when we flip it over..

I had a 3 way Dometic fridge in my caravan and it stopped working on 240 V (that was all we were using at the time). I took the fridge out, turned it upside down, sideways - you name it we did it, but still no go. I checked the eater element resistance and tat was all good. So I decided it was time for regas (ammonia). I was told that they could do it, but there was no guarantee that it would work, and it was going to cost me $700 to do it. I spent $1175 and got a new fridge - same model so that it fitted in tho hole. Well, the new fridge worked (and still does) far better than the old one which was the original fridge as fitted by Jayco.

There was no evidence of leaking at all, until I removed the insulation from around the heat pipe, and then I saw some yellow cake. That confirmed my guess that the gas had leaked out. Naturally no smell either or if there was, we were not there at the time. These fridges are damned expensive and are not really that good - their main plus is that they can run on gas or 12 V if required, as well as 240 V.

If the green one has sat for a long while the refrigerant liquid can congeal in the evaporator.
Number one method for release is to shake the fridge violently.(your risk assessment will require two coordinated strong people to achieve a good shake ;). Then try leaving it upsidedown, sideways, other side etc., keep moving and shaking to clear the blockage, then turnright side up and run it flat out and leave run for at least a day or two.
The refrigerant side of these isn't really serviceable and a changeout costs more than half the price of a new one, so persisting with the above 'repair' method is advisable ad nauseum until you are happy to throw the fridge out. The guys have mentioned the thermocouple issue on the other one. Don't give up on them and once they are running, keep using them. It's not like they are going to wear out.

Try this method and see what happens. Most likely it will work again.
When I tried it, I found the poor production quality inside, had allowed the separator screen to drop and found it made a rattle noise when shaken side to side or tipped on end, as GBC advises. If ok inside, yes do as he says, it will get things going, just takes a while.

Plug it in to 240v, as that is the only guaranteed supply. Gas jets could be blocked if you use gas, 12v connection could be dodgy if you use that.


If the fridge cools OK on 240v then you know its not the refrigerant or anything like that.

Scott , On your old chescold try cleaning the thermocouple first as these get dirty with soot and stop the gas flow. They create as small voltage when heated to keep the gas valve open, .they only work properly when clean. Use some fine sand paper and shine the end that sits in the flame. Then try lighting again you will find this may fix your problem.
