It is a Coolfreeze CF 40
The suspect board is the control board and is a 00552268 Rev 0
Sp-005 / 028-1-pc-vl2 #123995 2005.11.25.
My searches on Ebay et al tell me this board is not obtainable and I need to replace the display board, the control board and the wiring loom for nearly $300.
While on Ebay I ordered a 12v thermostat which arrived today and I fitted it. The Waeco is happy cooling a dozen cans of soft drink as I type.
The display board still has ER1 showing, no flashing error light.

Thanks DeBe for helping.
The thermostat idea came from posts on this board and I plagiarized it. On my way out soon otherwise i would go back and find and acknowledge the original people.
I put the unit in the butter compartment, powered from the 10v interior light and ran two wires down to the compressor. After doing this I realised I could have made a loom with plugs to connect into the board. No cutting or soldering. The thermostat would have to be mounted outside the fridge and i thought it would be beaten up by foldup chairs and tables ect.

Can anyone help me out?

I have a CF80 version A.

1. When plugged in fridge won't turn on at the control panel. No error lights or anything.
2. Emergency switch won't work either, thermisor is ok.
3. Voltage checked at the controlled module and getting 12.7V. Internal light also on. I even ran power directly to the module and nothing happened.
4. If I bridge T & C I can then turn on the display panel and the fan starts, also flashes error three. Motor pressure issue. I can turn off the display but the fan stays on till I unplug the fridge.

What now? Is the module dead or is the compressor not working?

Turned out the voltage cut out switch was corroded and cutting out the power. Cleaned up the switch and it all works fine.

Late to this party and my first post! I have 2 x 80lt waecos with the lcd display, I think I have blown both controllers when trying on 240v, replacement DANFOSS 101N0220 is cost prohibitive, I intend to run with the external temp controller like I do on my 110, just wondering if anyone here is handy with figuring out the component I have blown on both boards and would be happy to repair for me? I will of course be happy to pay. My mobile is 0404046610 or email jefahey71@hotmail.com, wife and I are planning our lap or 3 in the next couple of years. Thanks all

...my fridge controller is playing up on it's fastest speed due to high heat days but works fine on the two lowest speeds if that is worth a try!

 

edit: not a danfoss but a Wancool copy.
