I had the same problem with my magic cheff oven. I had to set the temp at 400 - 500 degrees to get to get an actual oven temp of about 250 degrees. The oven temp sensor checked ok with an ohm meter. Should be around 1100 ohms at room temp. I work in the electronics industry and know capacitors go out of range and dry out with heat and over time so I replaced the 3 or 4 electrolitic capacitors on the timer board. Cost me about $6.00 at Radio Shack and now my oven temp is right on the money. I realize not everyone may want to do this but it worked for me. Better than the $200.00 for a new oven timer control board. I have also found a company's website that fixes these boards for about $89.00 ApplianceTimers.com
Their may be any voltage problem can be occur in your home or otherwise oven heat producing transforming may not works correctly! if the fan runs heat not coming mean transformer only not working properly!
