When you buy a house having seen only the photos on the web, there are bound to be a few surprises. One was that the garage is fitted with a Controll-A-Door, which we soon found out hasn't worked for years. Yesterday I took the cover off, and I think I've found the culprit.
For the electronically inclined, just above the roach's head you can make out the track that was vaporised, and the scar on the PCB left by the arcing between active and neutral. The damaged track carried neutral. Should be an easy repair with a jumper wire and a new fuse, but I'll be standing well back for the smoke test.

I think there's a bug in your circuit diagram...
