How do you access internal fuse on 2003 Sharp R1500 microwave?

Do not know how to access internal fuse to check/change. Nor how to change either control or display panel. Does microwave have to be taken down to access any or all of these parts, please?

    Yes it's completely dead, no lights, no sound no nothing as if power isn't even reaching microwave at all. If it weren't one that's goes with stove & very good one I'd consider buying new, but be hard to find match with stove for reasonable price.
    Really needed to know if I have to take it down to get to fuse and it seems I do if located where or near where power cord comes in.

SOURCE: Makes a loud humming sound and blows fuse behind controll panel

Most likely a shorted capacitor is causing the fuse to blow. Easy and cheap to fix.

SOURCE: Change Fuse Whirlpool Gold GH7155XHS1

no the control does not come off from behind.

what you will find is the top vent grill has to come off first. it has 2 phillips screws that hold it to the top of your unit.
you will find 4 screws on the top, go ahead and take all 4 out and then pull the grill out from the top and hinge outward to remove/ once the grill is off, then there is 1 more phillips screw that holds the control board/ touch panel to the frame. remove and then lift up then out on the panel.
now that you are into the unit, make sure you have UNPLUGGED it first. the fuse is about 1 1/4 inch long white ceramic material with metal ends. you can find a new one at a radio shack or get one online for your unit. r/s has them for cheap and if that allows the unit to run again, great, but...
there was something that caused the fuse to go bad. so dont be surprised if you need a diode or capacitor to fix why the fuse went bad.

SOURCE: fuse blowing on the sharp microwave r-1874

your fuse will be located somewhere close to where the power cord comes in. It's not a regular glass fuse it looks like ceramic with the silver looking ends that's your fuse

SOURCE: Hi our Sahrp Carousel microwave LCD panle display is not working

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

SOURCE: My sharp carousel II microwave doesn't seem to

Is it dead, meaning no display, no light when you open the door and no beeps when you press a pad on the keypad?

We have the relevant service / repair manuals for this model and have uploaded it to our site here and here to help you.

They will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Most computers will open these documents automatically, but you may need the free Adobe Reader

I would suspect the 20A ceramic line fuse or the magnetron temperature fuse.

You can order parts from Encompass here or you can call them toll-free at 866-779-5835.

20A ceramic fuses are available at local appliance part stores or places like Wal-Mart and Lowe's.

I have the Sharp R-1440 carousel microwave oven and it won't shut off when I close the door. Do you know how old this oven might be? Model R-1440; Serial 123662


Check and change door interlock switches or check for condensation problem on control panel, (internal).
Hope that helps.

No power not even a clock i hve checked outlets


Well, there is a fuse in these units which sounds like your problem in this instance. You can get to it by removing the outer panel on the microwave. To do this, look for all screws/bolts on the back/bottom of the microwave and remove them. This will let you remove the outer panel and give you access to the internals. Make sure you unplug the microwave first before opening it and don't touch internal components for at least an hour after unplugging it to stay safe. The fuse can be replaced at a hardware or electronics store. Let me know if you need any more help with this.

Sharp R-150 microwave made a buzz sound and shut off, no power to microwave


Hi,
When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. Also usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven.

Sharp microwave suddenly died !


The high voltage transformer that feed the klystron tube usually has a cartridge fuse on its 110 v side.

YOu will have to remove the case to access the electronics... the screw should be obvious...

Note.. you are handy- so the obvious (unplug first) and the even more obvious - keep fingers and metal away from all capacitors in the power supply area.
