Oven not working properly

Do you mean 200 degrees Celcius or Farenheit? If Farenheit then the most likely culprit would be the thermocouple in the oven which can usually be replaced relatively easily by someone mechanically minded, if Celsius then you should suspect the elements although a working broiler would suggest that there is at least one element that works fine. Maytag says; "Why won't the oven heat up? First, make sure you've properly set all the oven controls. Check your user's guide for more information on your model's controls.(see below for the link to the manual if you need it) If your range offers the option of a delayed oven start, check to see if it's been selected. If so, the oven won't begin to heat until the selected time. If your oven has a lockout feature, check to see if it's been selected. If so, it will prevent you from using the oven. If your oven still won't operate, please contact an authorized Maytag service provider for more assistance." Here is the link to the manual; http://www.maytag.com/assets/product/8113P564-60.PDF and here is the link to Maytag Service if you need it - hopefully not; http://www.maytag.com/support/service_parts.jsp The other possible culprit would be the electrical supply to the oven - it may be adequate for the stovetop or grill but the oven may draw more power than the circuit can handle - even if it was fine before, this can change and may be caused by corrosion, rodents, overloading etc. and may not necessarily trip the breaker switch - if you suspect this at all then get a qualified electrician to check - it shouldn't take long to check so should be cheap, although repairs if necessary may cost more Hope this helps :)
