    Do you hear the normal sound of the high voltage section running?

    Is it louder or quieter than usual?

    From what you describe, it could be one the following, but your answers may help narrow it down:

    - power replay on control board
    - magnetron temperature fuse
    - high voltage transformer
    - high voltage capacitor
    - high voltage rectifier diode
    - magnetron

    Please reply back.

Your keypad has failed.

It would need a new control panel frame, which comes with the keypad.

You simply remove the circuit board and plug it into the new frame.

It is part # FPNLCB070WRK0 and the best place to order Sharp parts is Tritronics.

SOURCE: sharp carousel microwave doesn't spin

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

The best place to order Sharp parts is Tritronics. You can also call them at 866-779-5835

SOURCE: Sharp R-1490 microwave 2000

the fuse to the magnetron may be blown or the mag it's self is gone. if the door switch was bad the unit wouldn't rotate the carousel. if it is the fuse (check with a multi-meter and check continuity across both side of the fuse, acheap one will do) if it is good, time to replace the micro, as they are cheap and repair would cost more than to replace. hope this helps.

You probably have a defective magnetron or blown fuse supply power to magnetron.

SOURCE: Sharp carousel microwave, Model Number R-1505F, is not running

This is usually caused by either a bad bottom door switch or a loose bottom door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

See http://www.microwavedisplay.com/doorsw.txt

If you only need a switch, you can order a universal type here for $5 postpaid.

We have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

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.

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work


Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

Sounds like the inverter (power supply for cooking) or the magnatron which does the work----neither are cheap parts.

Re. Viking DMOS200 1100 watts microwave oven does not turn on


I'm guessing that's a VMOS200?

If so, that's a rebranded Sharp R-530ES (as is the Dacor DMO2420S) and its secondary interlock (bottom door switch) or that switch's mount is bad.

See this file on door switches. If you only need a switch, you can order a universal type here for $5 postpaid.

The Sharp R-530E service manual will aid you in disassembly and it is here.

Yesterday, my sharp carousel r-1460 went dead. I took apart the front keypad and replaced the 20amp fuse behind it. the microwave light and fan work.But, when I start microwave to cook something, pop! fuse...


If the 20A fuse is blowing, it is often the high voltage transformer or magnetron. If this is the case, and the microwave is not under warranty, replace it. Residential microwaves are generally considered disposable. Parts and labor are just too expensive. A magntron or transformer can cost more that half the cost of a new microwave.

GE XL1800 Micro fan won't shut off after light burned out


The problem appears, at least in part, to the door latch circuitry which cannot be serviced by the owner. If the unit is still in warranty, call GE customer care. If not, replacing the unit is your best bet. I just bought a new GE 1100 watt oven with great features for less than $100 If the door dosen't latch correctly, you could be exposed to dangerous microwave energy.

No turntable, no heat. Light, vent fan and keypad all work...


That would be a problem with your primary interlock switch or its mount.

NOTE: There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

The interlocks are highlighted in the diagram below.

I don't hear the fan, the carousel doesn't spin, nothing works but touchpad & light


It sounds like you may have an intermittent door switch or loose door switch mount.

Does it work differently when you wiggle the door?
