well, because your fuse tripped, when you turned the unit back on , the clocks on automatic
so you need to set the clock to manual timer, so at least one or the other will work
theres a good chance its just your grill element, but you need to get your clock back to manual before youll know if the ovens working normally first
Re: manual required for Homark oven as it has tripped my fus
Grill element may well be going to earth under load and may need replacing.
There are no Homark Technical manuals at all. User books seem to get passed around among users as available – there is a thread further down this forum if you wish to investigate.
I would suggest that you get a repairer to have a look at the grill at your earliest opportunity.
