A microwave can be dead for many reasons.

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

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 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.

My over the stove Sharp Carousel Model # R-1505F turn table stopped turning. What part do I need to replace. Also, I broke the glass turn table plate. What size is that and where can I order another...


Sears Parts Direct has the parts diagrams and many parts for the R-1505 microwave. The glass plate is part 4-3 ($33.99) on this page: http://www.searspartsdirect.com/partsdirect/part-model/Sharp-Parts/Microwave-Parts/Model-R1505/0958/0123370/50019999/00001?blt=06&prst=&shdMod= .


Without more tests, I can't be completely positive but the turntable motor is the likely problem. That is part 1-4 on the list above. However, it could be a wiring problem with the wiring to the turntable motor.

Partstore.com has many of the parts as well: http://www.partstore.com/Model/Sharp/Sharp/R1505.aspx .

I hope this helps.

I have a Sharp Carousel II microwave oven mounted above the range. It went dead when I pushed the start switch. The circuit breaker to the unit was not tripped. I don't know where to find the model number...


Model number is on the side of the control or along he bottom of the frame. The control panel should be removable with a screw or 2 and sliding up to unlatch. the fuse is behind there. To remove it off the wall there is 2 screws coming down from the cabinet above and the unit tips towards you and lifts up off a lip on the back plate. Eric

How do I uninstall an old Sharp R-1450 Carousel over the stove microvave oven? I removed the screws from the top that it hangs on and it still won't move. Help and Thanks.


You need to remove the grill above the door to find two more screws that go straight to the back wall plate. They will be on the left and right side. That is the only other way that they mount to the wall.

Good Luck

A blown breaker is usually a problem with a door switch or door switch mount.

If you or someone you know wants to look into this, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

In fact, I have uploaded the entire service manual for this to our site here.

If you find a bad switch, it's best to replace them all.

Please write back with more details if you need further help.

No power


Usually they do have fuses in side as well as the one in the mains plug. With microwaves I would get an engineer rather than take it apart yourself.
