Sharp Microwave turntable motor

[RichK]

Hi,

Anyone know where I can the turntable motor for this microwave oven, for
less than a new oven itself ? )
Checked a couple of places on the net, but they are pricing it around $50.
It's a joke. Is there maybe a universal solution that would keep my body
parts (arm & leg) intact

Model R-3A87 or R3A87

Need: Turntable motor PN RMOTDA161WRE0
MC8 120VAC 50/60Hz

You can call around to some of the electronics parts suppliers that
sell parts for servicing appliances and electronic equipment,

Called a couple, but they all want $50. Cheapest was $42. For that I would
install a hand crank and turn it each time I'm cooking

Using parts from a scrapper unit, does not gaurantee that the used
replacement part will be reliable.

I'll try to keep an eye open for a thrasher, but you are right it may be
just as bad. I took the motor and gears apart. The problem was a real
cheap plastic set of gears that got stripped - nothing one can fix with
epoxy. Seems the current trend in applience design is to include one part
which is sure to fail and make the appliance a nuisance to use, such that
you'll buy a new one. If the gears were 50% bigger, the cost would not be
any different.

At this point, you have either two choices. If the rest of the oven is
in good order, you can either buy a new motor, or replace the complete
oven.

I seem to remember that there were turntables once which were spring
powered, but do not see them anymore.

Of course I could put this 99% good oven in the dumpster, but I always try
to exhaust all options, before I do this. It may even be more costly or
time consuming to repair, but within reason I give it a try. It's a
challange. Anyone can carry it to a thrash )

As for making a manual crank, this is a funny one. I just hope you are
not serious.

Yes, that was a joke ...but I was thinking of some way to do it.
There's very little room however.

From reading your comments, I personaly would have never spent all this
time and agrivation to fix a microwave oven. If this was my oven at
home, I think my wife would have thown both me and the oven out by now,
in claim of being chinsy over such a small thing!

I have one large Panasonic oven that's over 25 years old. Very simple
controls. Takes two people to carry it. Still works Tray does not
turn. I can sure say, they don't make them like they used to.

This much newer Sharp, has a piece of sh*t turntable motor, designed either
by a nincompoop of an engineer, or some sly marketer.

Infact, about 8 months ago, our micowave oven started to make some
noise from the turn table motor. I found the bearings to be starting to
fail. Since I didn't want to spend the time on it, I put it back
together. I then went over to Sears, and bought a new

You're either much richer JerryG, or love to watch your local dump pile grow

Worked on a lot of Sharps and the turntable is plastic crap,so are

most of the others too.They are interchangeable in a lot of them so
look for a scrapper and test the motor with an external 12v[UK] hook
up.
Replaced one two weeks ago under guarantee and thought it funny it
went after four months,the lady said she had defrosted a 12 pound
turkey in it!'nuff said.

The plastic repair specialists can sometimes repair those gears - might be
worth asking, but since there are so many microwaves dumped in the tip these
days why not grab a couple and see if you can find a good motor

I would cannibalize one, but I do not know of a microwave "graveyard"
Years ago, when city dumps were not regulated, you could go and find what
you needed in cases like this. Nowadays, I don't even know where take the
old appliances. My township charges about $50 for disposing a large TV or a
wash maschine, but they do not tell you where they go )

The local tips are my graveyard - they have a recycle policy and I get some
good stuff from them. The tip at nearest big town (50,000) has lots more stuff
- usually there are at least a dozen or so microwaves there at any one time.
Local tip charges 50c or a $1, big town tip which runs the recycle program as a
business might charge $2 to $5 for a good (apparently) m/wave or computer etc,
and you can bring it back for xchange if NBG!

Thanks for that link. There's a local group. Not so much for the subject
at hand, but would like to give stuff away, which is no longer needed but in
good working order.

From our experience, the motor would have to meet specifictions, both
mechanical, and electrical.

You can call around to some of the electronics parts suppliers that
sell parts for servicing appliances and electronic equipment, but in
the end, they may have to order the same part as the one from the
origional manufacture.

The only other alternative you have is to get a scrapper microwave oven
that is if the same manufacture, and the same model, or the same for
its parts. Using parts from a scrapper unit, does not gaurantee that
the used replacement part will be reliable.

At this point, you have either two choices. If the rest of the oven is
in good order, you can either buy a new motor, or replace the complete
oven.

As for making a manual crank, this is a funny one. I just hope you are
not serious. You would not want to take the chance of having something
in your microwave oven that is not rated for its environment.

It is not recomended to substitute replacement parts unless properly
rated, or use replacement parts that are not rated to be used in a
microwave oven. The devices used in these appliances are rated for the
conditons of use.

Many types of plastics, paints, laquors, and materials may possibly
break down, and release toxic gasses, or may have a risk to catch fire.


For the parts used in appliances, they must meet very strict standards
for their location of application.

From reading your comments, I personaly would have never spent all this
time and agrivation to fix a microwave oven. If this was my oven at

home, I think my wife would have thown both me and the oven out by now,
in claim of being chinsy over such a small thing!

Infact, about 8 months ago, our micowave oven started to make some
noise from the turn table motor. I found the bearings to be starting to
fail. Since I didn't want to spend the time on it, I put it back
together. I then went over to Sears, and bought a new one right away.
About an hour later, it was unpacked and on our counter, ready to heat
up things for our supper. Since the old one was still working okay, I
donated it to a local church in our area.
