Theres an appliance repair shop across from the old grammer school on Blackburn rd. Aisian lad called Aslam runs it & is qualified to fix microwaves. He served his time on same course as me. Never touch the cap on a microwave, they can store up to 6000volts & will kill. We were taught to discharge them twice before working on them cos u only touch them live once! May be with age of it that a new unit may be more cost effective though.
