When you say that the oven won’t start, can you set the unit to bake and it shows that it is supposed to start but won’t lite. If this is the case, then check to see if the igniter is coming on. If it is then test at the oven safety valve to make sure that there is 3.2 to 3.6 Vac at the valve. If there is not proper power then replace the igniter.
