how do i fix my hygena classic 910g gg900 oven?

i recently left the grill door closed on my hygena classic oven and from then on it stopped working. after looking at your website, i found i had to open up th e cooker and press the red reset buton. Thanks for that advice. However, although the grill works fine, the oven does not work at all. no gas, no light, no sounds when trying to ignite it. Is there 2 reset buttons?
