Francis was very quickly able to analyse the problem and work out how to fix it, including removing, examining and remounting the cabinet. A new transformer had to be ordered, so he disconnected the faulty circuit, put everything back in place, and returned to do the actual repair a couple of days later. A very nice man, quick and efficient. I also appreciated that he wore a mask throughout, which gave me a lot of confidence having him working in my home at this time. Would definitely recommend.
