went to this today intermittent lock out. outer 2 lights on . burner would light for 4 sec then go out and repeat until it locked out . removed the cover and it was still sparking while the burner was lit . checked continuity of probe and lead which were ok . suspect the board - heck what a shock £220 at merchants looking on line to find one cheaper

Probably to late here Ant but there's a firm online that does refurbs with a years warranty! Pointed the custard in there direction as an option rather than pay for a new replacement! I got the custard to order etc so that the onus is on them and they also have to wait in for delivery! All you do is swap the PCB, the custard then returns the old one to the refurb company!
