Customer Question
Waeco cf 40 starts...

Waeco cf 40 starts up when on 240 volts, but cuts out after a few minutes. It then comes back on and runs for a little bit longer, then cuts out. It runs perfectly on 12 volts. This issue has only just started - please help!

Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram?

Not sure how to check the fuses!

Mechanic's Assistant: What year is your 240?

We think its about 5 years old.. we can't remember!

Mechanic's Assistant: Are you fixing your 240 yourself? What have you tried so far?

Nothing!

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I don't think so!

S​orry for the delay in someone getting to your question. I am in California and it is still early here. This sounds like the transformer is getting hot and may be shorting out and beginning to fail. That would account for the erratic performance. It might also be a loose connection in there. Some testing would be needed to find out for sure. Do you have a Service Center anywhere near you? That would be your best bet if you can't find any loose connections in that circuit, either in the unit or at the power source. Hope that gives you some direction here. Please get back to me if you need more as all follow ups are included in our fee.
