Someone gave me a twenty-year old Sharp Carousel in cosmetically
perfect condition. The inside even smells new. The AC stuff and bells
and whistles are working. The turntable coupler (very tiny plastic
square plug that sits exactly center and connects the glass turntable
and turntable spindle to the underbelly...allowing the glass to
rotate) is broken. A replacement sells online for $10 shipped. I
searched to see if microwaves are worth repairing but couldn't find
anything, so I thought I'd post here.
Would a broken $10 coupler indicate problems with the microwave that
can't be seen? Thanks.
My guess is that the broken coupler indicates only that someone clunked a
big ole ceramic bowl into the nuker that broke the thing.....or that they
inserted something so big that it 'stalled' the carousel mechanism which
then snapped the coupler. Either way, I wouldn't worry about it.
Three thoughts, though:
1. Have you tested it, just to make sure it heats? There's no harm in
running it WITHOUT the tray turning (just like ALL microwaves used to be!)
You could even use it like this long term if it's an efficient oven with
proper microwave dispersion.
2. Buy yourself one of those cheapy, $2 micro leak checkers to make sure
the door seal has integrity.
3. New microwave ovens are so inexpensive these days (for three times the
price of your replacement gizmo, you can almost buy an entire oven)...why
not just get a new one?
My 2 cents.

I just had mine die after 30 years of use,with only one repair.
the HV cap shorted 10 years ago,I replaced it and the HV diode for $25 part
If the oven is still heating well,I'd buy the replacement part,it should
not be that hard to replace.
Your power output may be down after so many years of use,though.
Newer MW ovens usually have 1000W or more,but generally smaller oven
they also have more keyboard features like sensor cooking.

I had to replace a coupler a number of years ago on a 12 year old
Panasonic microwave that got heavy home use but was otherwise working
fine. I suspect that after years of use, the expansion and contraction
of the plastic from heating and cooling eventually caused a microscopic
flaw in the structure of the plastic to crack. Replacement for me was
as simple as gently pressing the new coupler straight down on the motor
shaft. The oven lasted another 3-4 years. I thought I had made a
Depends on what it takes to install it. If it's a perfect drop in
that fits, then maybe. Otherwise I can't imagine screwing around
installing a 20 year old microwave. Just not worth it. Also newer
ones are more powerful, more efficient and not that expensive.

Hard to find one that size today. It also has a rotating antenna - so
it does not need a rotary table for even cooking. Which means it will
take a 9X12 pan without any issues
Coupler failure is pretty common. I inherited a MW with that problem and
glued the coupler back in place.
I first tried Liquid Nails, but that didn't hold. Then I stepped up to
super-glue. The MW has worked swell for the past four months.
Thanks everybody! I fixed it with a new coupler. Works *really* well,
ten times better than a small unit I bought in 2007. Whoever said you
could use a microwave without the turntable--thanks for the reminder.
I didn't know if I could test it without the carousel rotating.
*Just a note to anyone in the same situation: make sure you insert the
coupler (which retails online and/or in "reality" for $10) with the
"overhanging lip" in the proper position. Otherwise, the plastic may
crack or at least experience a lot of stress. And no, you can't get it
cheaper online; you'll pay as much because online repair sites charge
