set the oven on its lowest temperature say 50 degrees and see what happens if it get very hot then your thermostat is probably faulty
gen element for this model is this one 2500W

also beware there are 2 different thermostat fitted to this model. the stat changed in july 2003 from a Rathgeber made stat to a Diamond H made unit
both are different so I suggest you ask the site shop for the correct one should be either part no
C00199551 or C00231795
