WAECO CDF-40 issues NEED HELP

I posted on this issue last year and after a year of battle. The repair cent in Portland determined the issue the unit needs a T-Stat. But Doemtic Waeco says it is no longer available. They did not supply the part number for the T-Stat but is there anyone out there that knows where to find used one or something?

I have come so far on this issue and to fail now is a huge disappointment!

The Fan and Control Mod have been replaced. They know its the T-Stat because they were able to see unit fail on hot days and they jumped it and it worked. Thats what Dometic told them to do.

any ideas ?????????????

I am sorry in advance if i am not using the proper etiquette for the forum

here is the original post link from last year

Hi thelyndy, Since I cant post pics on here, try The Grey Nomads Forum in Techies Corner on page 3. You will find pics on my Waeco CDF-40 which had a thermistor problem & my solution to it as it was imposible to remove the built in thermistor due to pipe work being in the way. Cheers Daryl

The thermostat controlling the electronic unit in the Danfoss system only conducts a milliamp or so of current and can be prone to dust contamination.

A dextrous person can dismantle these and clean the contacts, the assembly slides apart quite easily.

The thermostat is a Danfoss mod.8, readily available.

Are you saying under the slide controls if taken apart one could clean contacts and make it work?

Is it a CF 40 or a CDF 40/45? The CDF range uses Chinese compressor, therefore control circuitry could be different from the Danfoss versions (CF models)

Sorry, CF 18 also uses Chinese "WANBAO" compressor.

Yeah, just looked at your referenced photos; definately a Danfoss !!

Looking at the Waeco website shows that CDF-40 is not available any more. Now have CDF-11, CDF-35, CDF 45. These do have Chinese compressors as well as the CF-18. These models only have 2 year warranty (comp) and 1 year on the rest of it, and have less freezing ability than the Danfoss models (CF-40/50/60) etc which have 5 & 3 year Warranty and use less power.

PS Some Danfoss compressors are made in China as well. (240V)

Mine is the Danfros for sure with the slide controls for temp and power. There is one slide control for the temp and another for the power. The control mod has been replaced and the fan. Repair center in Portland, Oregon USA determined it is the thermostat and was told by Dometic USA, that the part is no longer available.
