I recently took a short trip North to visit a distributor for the American Range product line. American Range has been making cooking products for the commercial and restaurant market for many years, and recently has taken their product knowledge and scaled it down for the residential market place. During my visit, I took some photos of a tear down on one of their 36" ranges to highlight some of the basic features.
Most ranges built by American are all gas ranges, and as you will see in these images, simple and durable seem to be the best way to describe them. There are no electronic controls of any kind, and everything operates on 110vac from the fan motors, to the oven and indicator lights. Looking at the rear with the cover removed, you can see most everything is easy enough to get to and service, and this range even makes it easy to get to the back of the unit, since casters are used instead of stationary legs at the rear. Simply lift the front legs off the floor and role the unit toward you for servicing.
Access to the surface burner valves and oven thermostat can be accomplished by removing all the burner knobs and two screws, one on each end, that hold the front panel in place. The oven door switch is also located on the right side of the panel, and care must be take to prevent damage during reassembly. The oven door is quite heavy and can be removed once the hinge keeper plates have been removed. And the oven bake burner assembly can be accessed by removing the bottom trim, and then pulled from the rear of the range. Each of the surface burners are held in place with screws, and a rubber seal helps control the air leakage into the burner as well as protecting the inside of the range from spills.
Overall, I liked the quality of the range and the very simple approach to the design. No extra bells and whistles just for the sake of having them, everything about this range is designed with the residential chef in mind. And for the service technician, most everything is easy to get to, including the wiring diagram which is right on the back panel, just in case.
