Money for bad dishwasher board.

Even Breville will conk out after a while. I had the temerity to clean the inside of our convection toaster oven with Easy-Off. Nope, the metal is evidently aluminized, and you know what lye does to aluminum. And the fan bearings are getting noisy. Now, we use it a good bit, still, they're $350 compared to $35 for an Oster. I doubt you'll get 10 Oster lifetimes out of the Breville, though they do look nicer. And I wouldn't spend $500 for a new commercial Sharp MWO, but I would buy a used one that hasn't been used too hard. Probably get one for less than half the price of new, better still if you don't have to deal with a used Commercial Appliance dealer.

In all honesty if I had to choose between this:

and this:

I would choose the Sharp. The Breville as nothing more than a standard junky residential microwave with fancy electronics, sleek outward appearance and soft close door while the Sharp is more robust and still has a whisper close door.

Because the Sharp heats MUCH more evenly on high power than the Breville, there is no need for fancy power levels, inverters and sensor functions.

What is your Sharp Carousel like? Frame, wave guide, transformer, ect?

My understanding is the Sharp Commercial has a few distinct differences compared to a standard Sharp sold today:

Larger power transformer, Stainless steal frame on the thicker side, direct cavity exhaust vent, bottom microwave energy feed, more even cooking, NSF certification, slightly more robust magnetron and fan, precision wound parts, squeeze door handle for whisper close.

However I am curious where your vintage Sharp carousel stands in all of this.

Of course the transformer and magnatron is going to be different depending on it's wattage output, so that's a moot point.
And yes, my Sharp has cavity exhaust and a substantial high velocity fan motor, all fumes and heat are channeled out through the magnatron's cooling fins.
Finally, indeed it has certifications listed, since it's mandatory for such an appliance.
As for distinct differences you mentioned, I don't see much difference which would indicate any reason for a major cost justification.
As I mentioned, I've checked out the schematics for both machines and they're pretty much identical in layout.

I've serviced microwaves at the repair shop, all types, including over-the-stove models, so I have some experience with them.

Right, however per any watt of power there is a level of efficiency and drive.

Is your model NSF listed? I know it would be UL listed, ect.

My Sharp is not a "commercial" product which would require that.

Right, however having an NSF listing makes for easier cleaning.

I am genuinely curious how your Sharp is built. You might be right about your Sharp using the same gauge steel and parts as a commercial model. To which I would say you scored yet again.

As I know it, the commercial appliances are rated differently due to the fact that they are used in "public" areas like convenience stores, by many many people, some who are abusive and/or slobs.
Plus they have to endure a lot more use, wear and tear.
So requirements have to be tighter, more strict, and yes germ-free for health reasons.
Which reminds me...... I need to do a cleaning of mine for some splatters.

Chet, this is the schematic for my oven, compare this to the touch-panel model of that commercial unit.
The differences between my $47 oven and the $500+ commercial are trivial.

And about a 50% duty factor over a 24 hour course vs a few minutes out of every 24 hours in home use.

I can't speak for your Sharp, however, most genuine Commerical units like Amana and Panasonic are built sturdier than their residential counter parts and are priced accordingly. Perhaps not the build quality of a 1980s Litton or Kenmore, but still a tad beefier than your domestic stereotype.

Remember, Sharp makes a $335 unit which is still cheaper than a medium sized Breville and many high end residential units if seeking quality for the lowest price.

I've used my Sharp oven DAILY for 22 years now.
In fact, it's used multiple times a day.
So if you figure only a once-a-day use, 365 days X 22 years comes out to over 8,000 uses.
