Microwave Microwave ovens are commonly used in both small family style restaurants and in fine dining facilities to help owners keep up with the fast pace of today's restaurant operations. Values range from $200 for small light duty units to over $2,000 for heavy duty, higher powered microwave ovens. Because they contain electronic components and controls, microwave ovens can be damaged by power surges and other electrical disturbances. Complete replacement of the oven is often necessary when such damage occurs. © 2004 The Hartford Steam Boiler Insurance and Inspection Company.     All rights reserved.
