Itho Daalderop CVE repair

Dutch manufacturer Itho Daalderop seems to have an electronics reliability problem. I’ve now repaired 4 fans from the brand.

One common problem seems to be that the transformer on the PCB of the CVE “Centrale ventilatie eenheid” breaks. It is a very common part that can be had for about €5, e.g. at Reichelt.

The epoxy of the potting cracks. Maybe it gets too hot, maybe unfiltered spikes on the mains net cause this. Of course, these units run 24/7, but I’d advise anyone to add extra precautionary devices on any Itho appliances they might have.
