We see and repair this a lot. The problem is on the controller assembly.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.
Since the circuit boards are no longer available, repair is the only option. Details are here.
F2 on a KitchenAid mike usually means a Keypad short. Beware if it is a KHMS155LSS, it can self start on its own with a KeyPad short. A real stunning defect.
Controller is confusedA power
surge or random non-reproducible action of the universe may have
resulted in the controller's program ending up in an infinite loop. Pull
the plug for a minute or two to reset it.
If the problem persist, the main control board is faulty. God bless you
Inverter, converter, upverter, diverter :-) ...
are you talking about a magnetron?You cannot say easy and magnetron
replacement in the same sentence. Please watch out for the capacitor which,
under all circumstances, can cause severe pain/burns and at worst, can
kill.Before you do any of that ... check the door safety interlock
switch which is the problem in a BIG majority of instances. Check with a
volt/ohm meter. If this switch has failed because you may open the door when the
oven is running, everything will operate normally except there is no heat due to
the oven thinking the door is open because of the failed $2.99 switch.Thanks for visiting FixYa.com today.
Normally You have to
separate the door panels (as shown in the attached photo)
and then you'll see the previously hidden screw(s) you need to remove.Or you can watch a YouTube video (not a video I
made) that demonstrates how it's done.In some cases, you then
have to gently rotate the handle to unlock it.You can find
