What’s the most popular call to technical support test a PCB? You would be shocked at the answer.

I called my good friend at Resideo support and was shocked at the 2 most frequent faults installers which take up most of their time.
My books and videos explain central heating wiring and controls in an easy to follow way.
What did YOU call them about, leave a comment below.
