Microwaves are simple units that require minimal maintenance. Still, there are steps operators can follow to prolong the service life of these units.
Proper cleaning and maintenance are keys to safe and sanitary microwave use.
Routine maintenance for these units is simple, but necessary.
Rather than spraying cleaners directly onto components, which can compromise the oven's electronic system, apply the solution to rags or towels and then wipe the oven clean.
Once a month, check microwave performance by heating a cup of water up to a boil in a defined amount of time. For example, in a 1000-watt unit, boiling time is two minutes and 55 seconds. For a 2000-watt unit, this time is reduced to one minute 30 seconds. This field experiment ensures the oven and its heating elements are operating properly.
