Kenmore Glass top Convection self cleaning stove

Question

My oven does not heat up when it I use the convection setting.  The fan is working.  When I switch it to bake it heats up fine.  This just started last night and I have never had a problem before.  I have checked all the fuses and they all seem to be fine.  This stove is only 7 years old.  What can the problem be?  I do not want to call for service if it is just something simple that I can repair or replace myself.

 

Thanks,

Dee
