http://wiki.brandoncurtis.com/w/File:Microwave_Wiring_Diag this is a good diagram of a standard microwave. ive pretty much only seen on single mag ovens. "F" usually has a single wire from the hvtrans. "FA" is usually the gang off the cap.
The clicking sound would probably be a realy on the Circuit board. Do you have it set on Full power?? If it is set on a lower power setting the relays will open and close to try to regulate the cook power.
"F6" on a Whirlpool microwave means you have a shorted cook relay on your control board, which I can repair. Details here.

On many models you can open the door all the way and gently lift it off.
Otherwise, you have to do some disassembly.
The support page for your model, with manuals, is here.

"Recycling by repairing since 1982"
your better to dismount the door first
you may need to remove the top case
{no power empty the glass out etc incase you need to tip it over}
sometimes you need to remove the whole top panel
either look for the expoded view for it also
and take lots of pictures first and as you go
go for it you can do it
its easy
i recon 8 screws max for the top of the case
and 4 screws for the top hinge
and then lift off the front
four screw to take off the actual front
and 2 screws for the handle
,,,, thats 14 screws in and out
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
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.
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
helpful exploded view diagrams and order parts by entering your full
model number here.We'rehappy to help you with free advice and we'd appreciate your thoughtful

It of course depends on your full model number, but since you posted under the model KHMS155LSS, I'll assume that's it.You have to remove the grille across the top and may have to remove the control panel assembly.At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.You can find helpful
exploded view diagrams and order parts by entering your full model
number here.
In this model, there is one fuse (20A) and two thermostats which can be defective, any of which will render the oven dead.Dead meaning no display, no light when you open the door, and no response when you press a pad on the keypad.There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating
components.I have a copy in my files if you don't find yours.We'rehappy to help you with free advice and we'd appreciate your thoughtful

open *** and follow the cable which come from the back you will see an enclosure with fuse inside. Remove the fuse and replace with an other one with same specifications
