SOURCE: Sharp Carousel Microwave door latch stopped working door won't stay closed

Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

We have *critical* safety & disassembly info at our site, linked here: http://tinyurl.com/yzjozk

We also have this full service manual at our site: http://www.microwavedisplay.com/R1480_R1481_R1482_sm.pdf

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

SOURCE: R-4H84 Sharp Carousel II microwave oven stoped working

A microwave can be dead for many reasons.

The fuse is normally located on the floor of the chassis behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

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

SOURCE: Where is the light bulb in an old Sharp Carousel Microwave?

Microwave_svc's site is awesome! I was able to get all the help I needed for a similar Sharp Carousel microwave. My bulb was simply loose in the socket base causing intermittent bulb lighting. Microwave_svc's helpful links got me to the service manual and, along with a nice set of "tamper-proof" screw compatible TORX bits I bought at HarborFreight, I was easily able to get cover off, remove bulb socket, tighten bulb, re-install bulb socket, button unit back up, and, voila, the light now works without intermittent blinking. FIXYA!!!!

Many thanks to guru microwave_svc!!!!!!!

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: How to install latch and spring in microwave door

You need to know where the 'catches' are inside the choke cover on the door to remove it carefully without breaking anything or marring the cover. You might get inside and find that the post for mounting the return spring has broken and that is part of the outer door panel.

We have a Sharp R-410 LK and it stopped working except for the clock and timer. The carousel doesn't work or anything else! Could a major part have gone out or could it be something simple?


I couldn't find the wiring diagram of this exact model, but looking at a similar model diagram, it appears that the main fuse in the oven has blown or a safety interlock has failed. The clock runs all of the time of course, and so it is powered by a branch circuit. The main fuse and interlocks protect the rest of the oven (and you!). The fuse could have failed because of temporary overload or because a critical component failed, in which case you would need some profession help. If the oven is fairly new, it may pay to enlist a service tech, because some critical failures involve relatively inexpensive parts. You may find it budget-worthy to take it to a shop you trust that does this service, rather than pay for a house call. Good service techs can usually track this problem down in a few minutes. Microwave circuitry is comparatively simple (but dangerous if you don't know what you are doing).

My sharp carousel II microwave no longer heats food. Do I need to buy a new one?


The problem maybe the magnetron, or the inverter board if 7 years old or less, and possibly the keypad control board, by the time you add parts and labour cheaper to replace the microwave oven in the long run.
