Why these made the list
The current catalog contains five Commercial CHEF microwaves, so this guide covers all of them. We shortlisted the models by checking the stated type (countertop or over-the-range), capacity, convection support, and whether the seller lists a power rating. We chose the 1.7 cu ft over-the-range model as best overall because it is the only one with a convection mode and the largest stated capacity. From the remaining picks we grouped by form and size: the 0.9 cu ft countertop is the largest countertop unit, the 0.7 cu ft models are compact options in stainless and white, and the 0.6 cu ft model is the smallest. Prices on the page are live and read from the store listing; nobody at wikimicrowave.org has used these microwaves, so every claim in this guide comes from the stated specifications or the linked sources.
Things to weigh before buying
Countertop or over-the-range
The current Commercial CHEF lineup splits into two types. Four models are countertop microwaves that sit on a work surface and plug into a standard outlet. The fifth is an over-the-range model, designed to be mounted above your stove in the space where a range hood would normally go. If you are replacing an over-the-range unit, the CHMRC17GS is the only pool model that matches that description; if you want a simple countertop unit, any of the other four will work.
Capacity: how much interior space you need
Capacity ranges from 0.6 cu ft up to 1.5 to 1.9 cu ft. The countertop models are all under 1.0 cu ft, with the 0.9 cu ft CHM990B giving the most space among countertops. The over-the-range CHMRC17GS is the only model with a 1.5 to 1.9 cu ft range. Smaller units fit tight counters and single dishes; larger units can hold bigger plates and taller containers. If the seller does not list interior dimensions, use the stated capacity numbers as your comparison.
Stated power: the missing spec on most models
Microwave wattage affects how quickly food heats, but most Commercial CHEF models in this catalog do not list a power rating in their specs. The one exception is the white 0.7 cu ft CHM770W, which states 'under 800 W.' If heating speed is critical, choose that model. For the others, you cannot compare cook speed from the listing because no exact wattage is stated.
Convection: when you want browning and baking
A convection microwave adds hot air circulation to microwave energy, which allows browning and baking beyond simple reheating. Wikipedia describes convection microwave ovens as hybrid appliances that combine infrared radiation, hot air, and microwaves. In this lineup, only the over-the-range CHMRC17GS lists convection, so it is the only Commercial CHEF pick that offers that feature.
Finish and cabinet color
The Commercial CHEF catalog includes stainless, black, and white finishes. The two 0.7 cu ft models are the same stated capacity and type, one in stainless (CHM770S) and one in white (CHM770W). If your kitchen has a consistent finish, choose the one that matches rather than comparing specs, since the visible difference is mainly the exterior color or material.
Safe reheating and disposal
For safe reheating, the FDA advises covering food, stirring and rotating, and allowing standing time before checking temperature. Use a food thermometer to verify that meat, poultry, and egg dishes reach the recommended internal temperatures. When you replace an old microwave, the EPA recommends checking local electronics donation and recycling programs rather than putting the unit in the trash.
Questions
What is a Commercial CHEF microwave?
Commercial CHEF is the brand name for this line of microwave ovens. The current catalog lists four countertop models and one over-the-range model, with capacities from 0.6 to 1.5-1.9 cu ft. These are kitchen microwave ovens; the product types listed are standard home kitchen forms.
Which Commercial CHEF microwave has the largest capacity?
The 1.7 cu ft over-the-range convection model (CHMRC17GS) has the largest stated capacity range at 1.5 to 1.9 cu ft. Among the countertop models, the 0.9 cu ft CHM990B is the largest. The other countertop models are 0.7 or 0.6 cu ft, based on their product names.
Do any of these microwaves have a convection mode?
Yes. The over-the-range CHMRC17GS is the only model in the pool with a convection setting. The four countertop models are not listed with convection. If you want convection baking or roasting from a Commercial CHEF microwave, the over-the-range model is the one to consider.
What wattage are these microwaves?
Most models do not have a wattage listed by the seller. The white 0.7 cu ft CHM770W is the only one with a stated power spec, given as 'under 800 W.' No other model in the current pool provides a power figure, so you cannot use wattage to compare them.
Can I install the over-the-range model myself?
The CHMRC17GS is described as over-the-range, so it must be mounted above your stove rather than placed on a counter. The listing does not include installation instructions, so check the product manual or hire a qualified installer if you are not comfortable with the work. The four countertop models only need to be plugged in.
Is there any difference between the two 0.7 cu ft models besides color?
The stainless CHM770S and white CHM770W both have a stated 0.7 cu ft capacity and are countertop models. The white CHM770W is the only one that states a power rating, at under 800 W. The stainless model does not list a power spec. Otherwise, the main visible difference is the finish.
