Just changed the fan for a proper part cos it was screeching and a few days later the boiler fails, this time the fan is running freely but when it recieves whatever power (can't work it out on my digital multimeter) from the board it just buzzes like it's forgotten to spin and just is magnetically frozen with what seems like a 50hz buzz, it also attracts my screwdriver like an electromagnet, fan spins fine when plugged into mains.
I know I'm looking at a new board, or is this something weird anyone has come across before?
I'm worried of course the new fan has caused it, but how?
