SUMMIT offers the industry's widest variety of refrigerator-microwave combination units, with sizes that fit your space and designs to serve your needs.

Model MRF40B combines a mid-sized microwave with SUMMIT's popular compact CM40B refrigerator-freezer. The complete unit has a conveniently slim under 19" width for an easy fit in any tight spot. A reversible door with door storage for large bottles adds placement flexibility.

Enjoy savings in both energy and price with manual defrost operation that maintains stable temperature throughout the interior. Additional features include an adjustable thermostat, adjustable shelves and more

The MRF40B's top unit contains variable functions and power settings for quality microwave cooking. All of SUMMIT's combination refrigerator-microwaves are shipped fully assembled and ready to use. Plug the microwave, refrigerator-freezer, and a third appliance (such as a coffee maker) into our power allocator box and use its cord for safe one-plug operation. This system protects your circuit breaker and power line by limiting overall power use to 10 amps.

In addition to those models listed in our MRF series, SUMMIT can custom-build refrigerator-microwave combination units to your individual specifications. Contact us today for more information.
