Hi, the round spinning dial on my master control panel 5500 has stopped working. All other functions & buttons work. I opened it up & tried 99% iso swabbing the 2 contacts that touch, when the dial is spun either direction, but it didn’t make any difference.

Thanks for any advice!

It could well be a faulty (or dirty) opto-coupler – have a look at this thread (and the pictures attached to some of the posts): https://archivedforum2.beoworld.co.uk/forums/p/22025/182754.aspx#182754
