Overview
The Summit MHOTR242B is a 24 inch over-the-range microwave in black with 1.4 cu ft capacity and top-mounted ventilation for installation above a range. It includes ten power levels, auto cook presets, and a mounting plate plus exhaust adapter for setup.
This is a compact 24 inch width unit, narrower than the common 30 inch over-range microwave, which matters for kitchens with a smaller cabinet opening. Venting is top-mounted, so the space above the unit needs to stay clear for exhaust to work, and it can run ducted vertically or horizontally or ductless with the included charcoal filter.
- Ten power levels with multi-stage cooking
- Auto cook, kids meal, and defrost presets
- Two LED cooking lights
- Two grease filters plus charcoal filter for ductless use
Who it's for
Kitchens with a 24 inch cabinet opening above the range that need combined microwave and range-hood ventilation in one unit.
Pros and cons
- Fits 24 inch cabinet openings, narrower than standard 30 inch units
- Vertical, horizontal, or ductless venting options
- Child lock and eco mode for safety and standby power
- Mounting plate and exhaust adapter included for installation
- 1.4 cu ft capacity is modest for a family-size unit
- Top vent requires clear space above the unit, limiting install flexibility
Performance notes
Two grease filters plus a charcoal filter handle ductless recirculating operation, or the unit can be ducted vertically or horizontally through the included exhaust adapter. Eco mode powers down unneeded functions automatically after a minute of inactivity, and child lock blocks unsupervised operation. Ventilation exhausts through the top, so clearance above the unit must stay open.
