ASIN: B08H3BB3WFCategory: Over-the-Range Microwave Ovens

Overview

The MWO-OTR-H-30 is a stainless steel over-the-range convection microwave with sensor cooking, a traditional handle and combined vent hood function.

It doubles as range ventilation, with 2-speed fans rated up to 300 CFM that can vent outside or recirculate through charcoal filters sold separately. The DiamondTech interior is ZLINE's claim for scattering microwaves evenly, backed by a glass turntable and an included convection rack for browning.

  • 300 CFM 2-speed ventilation
  • Convection and microwave cooking modes
  • DiamondTech stainless interior
  • 2 year parts warranty

Who it's for

Suits kitchens replacing an existing over-the-range microwave that also want built-in ducted or recirculating ventilation, and want convection baking without a second wall oven.

Pros and cons

Pros
  • Combines convection baking, microwave and range ventilation in one unit
  • 2-speed venting up to 300 CFM, ducted or recirculating
  • DiamondTech interior aims for even microwave heating
  • 2 built-in cooktop lights

Performance notes

The 2-speed ventilation is configurable for external ducting or recirculating with charcoal filters, and convection mode uses the included rack for browning results that a microwave-only unit cannot produce.
