chescold 3 way fridge freezer

Can't be too much wrong as they are relatively simple in design !!
On 12 v and 240 it heats up an element, so this has to be an electrical problem, loose wire or blown element ? On gas the flame heats up a chimney inside the same tube as the element. The gas operation is a little more complex - there is a auto cut out which stops gas flow if the flame goes out. The gas pipes can get dirt in them which will block flow or there is a diaphram behind the controls which may deteriorate whith age. My Sadec is about 20 years old and started to play up on gas last month. After some searching I found someone who services 3 way frigs. It just required cleaning of gas pipes, cost about $80 to fix. Most frig brands use the same parts. This was the only problem it's given in 20 years! Don't give up on it - the hardest thing may be finding someone who knows how to fix it. Good luck
PS If you get it working, remember to run a heavy supply wire from the Battery (with an inline fuse) and fit a 12 v computer fan into the back (to improve air flow). These 2 mods will greatly improve 12v performance.

Do you have and can you use a multimeter? If so, you can check the elements (12V and 240V) yourself. If it isn't running on any of the three sources and you have tried turning it on it's lid and it still doesn't work, it doesn't sound good. But you won't be sure until you check the elements. PS. I am a gas service technician.

Jules it might have something to do with the previous owner

If your Chescold heats or warms up at the rear on 240v and it is level, you have a problem with the cooling unit. If there is no heat or warmth it will more than likely be the heating element. To replace the cooling system can cost around the $400 mark and to replace the element, about $125. New Chescolds cost from $600 to $1200

3 way fridges have to be level.
Not just to work, you actually destroy the cooling unit if you operate it off level. Basically what happens is the coolant stops circulating, overheats and forms crystals which block the system.
Every time you operate it off level you start this process.... driving is Ok as the vehicle is in constant motion, but park for a while with it running and look out!
The only fix is usually a complete new cooling unit- very expensive. Pity they don't tell most peopls this as many don'trealize the problem- also a very good reason to be very carefull buying one secondhand!
