We are traveling in a Troopy around the world and for the first 80'000km the CF 40 worked perfect. Now in Peru he's got the feeling to play super cool, but the battery and the beer just do not like it!
Meaning the thermo sensor does not work anymore. Electronically I'm not all to inexperienced, but with only a cheap muli meter and no further info it still is rather difficult. And google does not help much eigther except if you want to buy a new one.
So if anyone might be able to help, with diagramms or experience we (the yougurt eating part of our journey as well) would be incredibly thankful.
Thanks from Peru going to OZ in two month from now.
Hi thomhard. If you go to page 4 on this site there is exactly your problem posted as a CDF-40 & how i repaired it. Waeco use same thermistor in the range its a NTC 10K @ 25 Deg C, The orig has 2 thin black wires coming out of the foam above the compressor, & plugs into conector cp5 on a CF40. The reason i fitted the thermistor inside the fridge was because i couldnt reach the foamed in one. You will probably find the orig thermistor has gone open circuit. Daryl Ps there is also info on page 3.

I came to DeBe's report on page 3 which brought me quite a bit further, but the one on page 4, seems to be the solution.
Even thou I have some doubts, so one to think. I measured the Thermistor (with my real bad analog mulimeter) and did not get an open ciruit, but something of 15kOhm. <= not accurate at all!
Then if I disconnect the fridge from all power over night (does not mean that it gets above 5°C) the next morning it works perfectly for about half a day. To me that rather seems to be a dry capacity?
Anyhow thanks for the data of the thermistor, I'll definitely try that one first as it was my first bet as well. btw: with my supplier it costs 1.85$ ;o)
I'm off for a few days again, but I'll let you know as soon as I know more.
Regards from Peru thomhard PS: looking forward to get to OZ

I was told by an electrician friend of mine that waeco fridges make excellent boat anchors, but he might be a tad biased because he sells Engel fridges.rofl.
Hi william the third. Belive me Engels do give trouble. But I run 3 Waecos & more than happy with them. tomhard the thermistors seem to be affected by moisture & slowly go bad. Daryl
Oh well, isn't that the same with anything! Troopy vs Defender, Nikon vs Canon, Waeco vs Engel.... (there is a reason why things are written first!)
Anyhow at least our meat does not start moving by itself as something goes bad! And I can always take the beer out up ahead so it't ready when needed!
Thanks DeBe; I'll definitely post again one it's solved, but it might take 2 or 3 month till we're in OZ. Hard to find Electronic Parts in Latin America. In the meantime we continue to play manual thermistor.
Welcome Thomhard. The guys are so concerned about the welfare of your beer they forgot to welcome you to the forum. In particular welcome to this Australian forum. I wish you safe and happy travels, and I hope your beer stops freezing.

It's always interesting to see people's comments on Waeco VS Engel and their reliability. (We sell both brands). You certainly pay a premium for the Engel brand. We find most organisations who look for real reliability - e.g. mining, govt departments etc, end up buying the Engel, while most campers/fishers etc buy the Waeco. We see both come back with various issues, definately more Waeco's - but then again we sell more of them too. Both have extremely good warranties (3 years for both, with Waeco having 5 years on the compressor). But even though they may be fixed under warranty, you don't want to be in the middle of Oz when your fridge packs up. For this reason, I think the Engel is worth the premium. It is a more robust construction with less moving parts. But if you've got better things to spend the extra couple hundred bucks on, the Waeco is a good option for most travels!
