Commercial CHEF CHM990W 900 Watt Counter Top Microwave Oven,

Great little microwave and a lot of generic small u-wave thoughts
This is going to be more than most people want to know — but I’ve been using microwaves in this size/price/power class for 20 years and might be able to help a few people who are newer.1. This ‘Westinghouse’ is a good example and works very well. Amazon price and delivery are first rate.2. NO microwave in this ~$100 price class is made by the company that has its name on the front. Essentially 100% are either made in one Chinese factory or by Samsung in South Korea. The labeled manufacturer tells the real maker what specs (power, controls, etc.) he wants and they make it, package it to say ‘Westinghouse’ or whatever, and ship it to the USA. There is a ‘Rival’ model that is identical to this one except for details of the controls and the Westinghouse comes in white which the Rival didn’t. That’s why I bought this one — wanted an exact replacement but in white.The ‘works’ within a power range and maker may be identical — my two are. Fit, finish, screws, paint type, turntable — it’s ALL the same. The actual POWER may vary somewhat. The Rival was closer to 1100W while this one is a real 900W — needs a bit more cooking time than given for 1100W machines.3. Since the price/power range pretty well sets the construction, you should look for features you want and the control panel details show the biggest variation: Size of numbers, number of specific food buttons, does it have a +30 second full power button (Rival did, WH does not), color of numbers, etc. Latest models all have a child safety lock — if set requires specific keystrokes to make the thing go at the start. Color choices also vary. One label may have what you want in — say — red, while another will only offer black. Etc.4. Weaknesses/things to be aware of are similarly alike. In this price range they’re all baked enamel (‘good paint’) inside, which means that if you aren’t very careful about cleaning/keeping it dry the life will be about 3 years before it rusts badly under the turntable. For long life use a plastic cover over an open plate, open the door promptly when done and LEAVE it open until next use, remove the turntable and dry underneath each night. Damp paper towel if necessary to remove any spilled food as food acids will take paint off pretty quickly. A nailpolish mark on one of the dents in the turntable underside makes it a cinch to put it back each time.So far as I know, porcelain enamel (melted on glass) finishes are only on high end (and much larger) microwaves. They’ll take a lot more moisture. If you leave the door open, the lightbulb will burn out in a couple-three years but it helps keep the insides dry.Other than that READ THE DIRECTIONS. There are any number of long-life cautions there that aren’t labeled as such. The Westinghouse manual is excellent and only in English.6. EVERYTHING that fails on these machines is pretty easy to fix and all the parts are out there if you are cheap like me and want to keep a good machine in service as long as possible rather than just throwing it away every three years. The window over the microwave passage (silver-grey thing upper right inside of oven looking at front) is available — if it catches fire, replace it, cut to size (boxcutter knife) from a kit. The light bulb can be replaced but requires removing the cover over the high voltage internals: Don’t do that if you aren’t familiar with LETHAL voltage precautions. The turntable motor can be replaced rather easily — never had one go. The magnetron lasts for years: I have replaced one and it failed because of a factory defect. Ditto the fan. Maggy and fan are also in the killer HV area.It’s good to remove and wipe down the magnetron window every few months. Use a paper towel dampened with water and wipe firmly to remove food vapor deposits as they’re what catches fire but when that fire burns out it will likely have ruined the window. After wiping, LET DRY for several hours before using.You can even repaint the insides. Search ‘microwave cavity paint’ and read/follow the directions carefully. DO NOT use that paint indoors — it’s highly flammable and nasty to breath. Remove the microwave window and plug the hole with crumpled paper towel, just lift out the drive hub for the turntable. Let it dry a couple of days before bringing in/using.7. It’s possible to hang these under a cabinet and there used to be many models with the kit of parts to do it. Now, NONE. I think the lawyers killed that setup because IF YOU ARE STUPID and start a serious fire in the oven and it’s right against wood you may have a kitchen fire. So if you’re given to pouring your McD’s coffee on your … you know … or washing your gloves in gasoline and trying to dry them in the microwave, DO NOT EVEN TRY a hung installation. Otherwise cut bars (aluminum bar stock is good) to go inside the cabinet top and distribute the 30# load over the whole front-to-back distance, drill/tap holes for about 12-32 machine screws AND HANG WITH SPACERS AT LEAST !” long using a scheme that allows free air circulation over the top of the machine. Ideal spacing for the bars is about 15-1/2″ L to R and centered; that’s what the original kits did and the insides of this model are identical. CHECK CLEARANCES INSIDE to wiring and terminals.NEVER use a microwave for anything that might have a flammable solvent in it. Food or water washed items ONLY.NO MICROWAVE should be ‘turn on and leave the house for a few hours.’ In 20 years we’ve never even had a scary event but I don’t trust heating appliances at this power level with so many variables and while the machine IS well protected internally — there’s an over-temp shutoff, the top and upper surfaces are two layers all metal, etc. — extra safety precautions are still appropriate.

Great Microwave that will likely last for years! Good value for price.
Love this microwave! I had one similar that I bought in 2010 for $50 bucks in a store and it lasted me over 10 years. It’s a nice design smaller but not too compact, large enough to hold big plates and containers and other packaged meals. Easy to clean especially the outside where it’s black but nice front design with the stainless steel accents; clear number pad (remove the protective film on the pad or it will start to bubble and you will think that it’s part of appliance) easy to use with some quick features for the price point. This is a deal compared to the other ones out there that are almost $200. Even though the one I had was a different brand name, I can tell it’s still similar manufacturing design. To compare it was just a number pad slightly different design as you can see in my previous photos of my older brand Oster from 2010. This is why I chose this model Commercial CHEF because of my experience of it lasting until just recently which I think was my fault because of a spill which likely malfunctioned the number pad area. I’ve also bought other products from Commercial CHEF as well with good experience to receive something that was not damaged and working as advertised. Nice size, looks modern and under $100 this is an amazing price for something that will last for a long time if you take care of it. I prefer to not have the pull handle because people always touch it with food on hands and gets dirty easily. This is very quick to open, which is a small push and to clean it right after a quick wipe without having to wipe a whole handle regularly. It’s sturdy too, even though people can slam the door you don’t need to do that, but if you do, it has held up to that type of use in the past on my older one, and I believe this is gonna have the same type of endurance. You do have to set the clock after you plug it in and then it’s good to go. Others said they received the unit damaged, I did not. There was zero damage, and it came in the manufacturers box well packed with foam blocks when it was delivered, but it was not within an outer bigger box; maybe for other people it would arrive like that or maybe in the past they realized when they put in a big box it got banged around and would damage if the driver also couldn’t see that it was something such as a microwave that needed to have some proper handling and care upon delivery. I just got it today but I’ll update if there’s any issues but I’m hoping it will last a long time like my previous similar microwave, the fact that they were nearly exact design, the older one fit in the box like a glove to be able to get rid of which was ideal making an easy replacement. It’s a timeless clean modern design that would go well in any kitchen!

Works very well. Perfect size
