Very OT : Central heating - relay sparking
Anyone know how best to clean a PCB-mounted relay which is sparking?
I've tried cleaning the contacts with a little sandpaper, but that hasn't helped at all.
Is there anything other than dirty contacts that may make it spark?
It's on the PCB which control my central heating boiler. I've ordered a new PCB but that won't be here til Thursday and it may get a little cold in our house if I can't get this think working tonight.
