Commercial Microwave Repair in Denver

A commercial microwave in a restaurant, café or convenience store can run hundreds of cycles a day, and it wears out in different places than a home unit. Best Pro repairs commercial microwaves — from light-duty units to heavy-duty models with two magnetrons — for food businesses across the Denver metro area.

Common failures

• Heating slowly or unevenly. Heavy-duty microwaves often have two magnetrons, one at the top and one at the bottom. When one fails, the oven still heats, but cook times stretch and food comes out hot on one side. A failed stirrer motor causes uneven heating too.
• Shuts off when it gets hot. Most commercial microwaves have an air intake filter. When it clogs with grease, the magnetrons overheat and the thermal cutouts shut the unit down. Cleaning the filter regularly is the easiest way to extend the life of the magnetrons.
• Won’t start, or blows a fuse. Doors on a busy line get slammed constantly, which wears out the door interlock switches and the door itself. A misaligned door or a failed switch keeps the oven from starting or blows the main fuse.
• Keypad not responding. Membrane keypads wear out under heavy use; we replace the keypad or the control board.
• Sparking inside. Grease on the waveguide cover or damage to the cavity.

Safety

Microwave ovens hold a dangerous high-voltage charge in the capacitor even when unplugged. Diagnosis and repair should be done by a technician.
