sorry if this is the wrong spot but

I have a older sharp covection microwave(mid 70's) that can be used as a normal 700 watt microwave or a convection oven. today i decided to try and cook pot-pies using the convection part instead of the main gas oven. i set the machine to pre-heat too 400 degrees during which the machine let off what looked like white smoke or steam and smelled like melting insulation (maybe cause the convection part was never used before). after it got to 400 i put 3 pot pies in and set the timer for 32 minutes like the pot-pie box said. 32 minutes later the pot-pies are burnt and hollow(no gravy or anything) and like cardboard. the cardboard backing was also black in some spots. what did i do wrong. reading the manual its a 2 phase for convection. 1st is like a normal oven for pre-heating. 2nd is microwave but a fan runs to move the hot air so food cooks evenly. is there a rule of thumb for cooking food like this. like what ever time it says on the box divide it by 50 or something. i did the same thing on another microwave(non convection) i went to cook frozen bacon. put a few slices on a plastic plate with paper towels. 5 minutes later bacon is burnt plate is cracked at the bottom. i followed the cooking time of the box each time.
