While my CF50 Waeco operated fine on 240 volts, it started operating a bit erratically on 12volts and my fault finding indicated a poor contact or similar voltage drop, so I cleaned all plugs, fuses etc., but the fault remained. After several other checks and fixes failed to solve the problem I rang Waeco and when I told them the symptoms they immediately said it was a common problem caused by a faulty fuse on the circuit board.
As mine is still under warranty it will be fixed free of charge and I am confident that all similar problems will be dealt with as a warranty claim, despite the age of the unit , although I was told that nearly all have created problems within 2 years of the 3 year warranty.
Symptoms: The compressor starts running and (for me) after about 40 seconds the compressor stops, but the fan keeps going, so it still sounds like the compressor is running and then the red error light flicks slowly for a while and then the compressor starts up again for a minute or two and then stops again and the fan keeps going and this continued indefinitely as described above.
This is my second Waeco with the first one still going fine after 8 years and any dealings I have had with Waeco have been very positive and I hope that continues now after the ownership takeover I think I recently read about on this forum.
