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 MRF421BL combines a mid-sized microwave with SUMMIT's popular counter height CM421BL refrigerator-freezer. The complete unit has a conveniently slim width for an easy fit in any tight spot. The interior includes adjustable glass shelves and a crisper. The reversible door features a factory installed lock for added security.

The MRF421BL's top microwave includes 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.
