Households that want a microwave and a full oven in one tall cabinet end up with something like the HBLP752UC. This Benchmark combination wall oven fits a 49 inch column and draws 9,600 watts. A 1.6 cubic foot cavity on top handles convection, microwave, and both together, with a full oven underneath.
Running microwave and convection together is the reason to own the appliance, and it is also the hardest thing you can ask of it. The magnetron and its cooling system work at once with the convection heat, so they carry the heaviest load whenever that combined mode is on.
As the unit ages, those are the parts we look at first, along with the upper cavity’s cooling fan, which needs a clear path inside a tight cabinet. The two cavities share a control system, and the doors close softly. Our visit begins by asking which cavity misbehaves and in which mode.
Microwave energy and convection heat run at the same moment, so food cooks through quickly yet still browns. That is the main reason to choose a combination oven over a separate microwave and oven.
It works the magnetron and its cooling harder than other modes. That is what the appliance is built for, but daily long cooks in combined mode do ask more of it than average use.
The upper compartment has a cooling fan that needs room to move air, and a cramped cutout restricts it. Tight cabinets are a common reason a combination oven shuts down, so we check clearances.
