The service life for commercial microwaves varies, depending on use. In high use applications, microwave ovens typically have an average service life of between 5 and 7 years.
A big benefit of microwaves is that these ovens are one of the most low-maintenance pieces of equipment in commercial kitchens.
Operators can take certain steps to prolong their units’ service life.
Location plays a key role in keeping these ovens operating at peak performance.
Because microwaves are electronic devices, they require cool air to prevent overheating and to ensure they are operating properly. For this reason, do not place microwave ovens above equipment emitting heat, such as fryers or steamers.
In terms of cleaning requirements, operators should wipe down units throughout the day. Keep the oven’s air vents clear of dust and debris by vacuuming this area as necessary, thoroughly wiping down louvers and regularly cleaning out cooling fans to ensure proper operation.
Service techs use tools to gauge radiation leaks, but operators can perform this test themselves by shutting the door on a dollar bill. If it’s easily pulled out, chances are the door is not closing properly and needs servicing.
If the microwave’s panels and lights are cracked, it could cause problems if food moisture reaches the oven’s interior.
Due to the low cost of replacement, only about half of commercial microwaves needing repair get serviced. These mainly include heavy-duty types and combination microwave/convection ovens. Service calls range from faulty magnetrons or bad computer boards, which are big ticket items and not worth the cost to fix.
