Unplug, remove top, look under keypad, follow wires to circuit board, look for a silver rectangular capacitor, "may be under a plastic flap" discharge capacitor with a screwdriver across the 2 points, look for a small fuse near by in clips, remove and replace with same current rating, assemble before test because lethal voltages present when powered.

Hello,

the problem of this unit is power related.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the cooker, it goes straight into the power supply board which then circulates the current into the unit. So if the cooker doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

Hi,

I have the same model in my home only mine is black rather than stainless. The problem you are encountering is most likely due to a fuse that has blown internally in the unit. Before having it looked at be sure you have power to the wall outlet that the microwave is plugged into. The outlet is usually in the cabinet above the microwave, simply unplug the microwave and plug a lamp or other appliance to verify it is 'live'. If the outlet is live the repair for the fuse may be a done from the front if you have a bit of patients and basic knowledge of electricity. I would recomment calling a service company to make all repairs on this paticular unit as it can be very tricky. Let me know I can help further.

Hi there,
Things that we may want to consider are, It could be that the training or the technician's company have their "safety" guidelines and procedures that they have to follow or the technician could be afraid of the leaking radiation causing trouble for him and for you.
I also believe that a faulty waveguide would disperse radiation to any direction. However it can be the cause of the radiation leaking outside. perhaps the lining he's talking about covers the entire microwave inside and not just some part of it.
If you'd ask me getting second technician out and paying that $60 without the assurance of them replacing it, I strongly recommend that you just get a new one and let this one go.
It would ensure you a working unit and more safe environment (since AHS won't replace it).
Your question about how did he know that the waveguide is pitted I don't know how he knew it but the wand he used definitely detected a radiation leakage so I think that what caused it and how it happened should be less priority now and what you should think of is to have a hazard free home.
Hope this helps!

That model should be KHMS2050SS0, KHMS2050SS1, or KHMS2050SS2, I think.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid with a one year guarantee.

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.

This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.

Details of our service are at our Web site.

Feel free to contact me directly with your brand, full model number and symptoms for more information.
