Customer was complaining the both grill elements had stop working at the same time so i called round with a new regulator, did some tests while i was there and both the elements tested fine and so did the regulator? she then ADDED :rolls: that if she turns on the top oven along with the grill then the grill works. Any ideas? ran all the normal tests, no suspect wiring that can be seen, at a bit of a loss with this one.
