Hi guys, if it's any help, I've figured it out, on the back, lower left hand side, there is a board that controls the main oven from the timer, on it is a couple of relays and a 125mA fuse not anti surge or anything long lasting just a basic run of the mill fuse, checked for overloads etc replaced it and it's working fine, nice little earner for the call out and first hour charge, hope it helps someone out, Gary
