Hello, I have a Waeco CF-50 fridge that works beautifully on 12 volts but has started cutting out after a while if connected to AC (mains) supply. It is the newish type with digital temperature readout. Few years old. It previously worked fine on AC.
The pattern seems to be that it starts and runs fine, cools the fridge down a few degrees, then stops altogether. The shutdown is complete and includes the digital display going blank. No error light.
Sometimes it restarts after a while, runs for a bit (much shorter duration this time), then shuts down again. I can also restart by unplugging the AC cord and the same thing happens - runs for a while, then shuts down. When it does start back up, the compressor seems to run at a lower RPM initially before stepping up to full speed, then soon afterwards it stops and everything goes blank.
I tried a new power lead with the same result. Fuse (next to AC socket) looks good. Can't see any visible problems with the PCB that sits at the back of the power sockets, or with any of the connections.
I'm wondering if there's an overheating issue on the AC side of the control unit that sits at the side of the compressor with all the wires running out and connections marked by letters (the compressor says something about thermal protection or overheating protection on its side). I don't know whether the compressor has separate AC and DC windings, or the control unit includes a transformer/regulator to convert the AC to DC.
I've seen a lot of Waeco problems on forums but nothing specifically about a failure in only the AC side of the unit. Any help appreciated -thanks.
