The short version

Fitting a microwave and a wall oven into the space of a single appliance sounds like a compromise. The GE Profile PT7800SHSS largely avoids that trap. The convection oven portion performs like a standalone unit, and the microwave section is more capable than the built-in microwaves found in cheaper combo models.

If your kitchen layout does not support both a dedicated microwave and a wall oven, or if you are working with a single cutout, this is one of the best options available at this price point.

Who this review is for: Homeowners with a single 30" wall oven cutout who need microwave functionality too, or anyone doing a kitchen renovation where adding a second appliance cutout is not practical or desired.

What you need to know about this oven

The PT7800SHSS is part of GE's Profile line, which sits between the standard GE appliances and the premium Cafe and Monogram lines. Build quality reflects that positioning — it feels and looks like a serious kitchen appliance without the price of GE's top-tier products.

The combination format stacks the microwave above the convection oven. The oven cavity is 5.0 cubic feet, which is a full-sized oven space. The microwave is 1.7 cubic feet, which handles everything from reheating to convection microwave cooking.

True convection means there is a dedicated heating element surrounding the fan, not just a fan moving air around a regular heating element. The difference shows in baking results.

Performance in real use

Convection baking results are consistently good. The dedicated convection element means temperature is more even than fan-only systems. Baked goods brown properly on the bottom without over-browning on top, which is the most common failure of lesser convection ovens.

The microwave handles standard tasks well. Reheating is even, and the convection microwave mode — which uses both microwave energy and convection heat — produces reasonable results for things like reheating pizza or cooking small items quickly.

One thing worth knowing: using the microwave while the oven is preheating or running is possible but requires some coordination through the control panel. It is not as seamless as having two completely independent units.

Pros and cons

    Pros
  • Full 5.0 cubic foot oven in a combo unit
  • True convection produces excellent baking results
  • Saves a full appliance cutout in your kitchen
  • GE Profile build quality is solid throughout
  • 1.7 cubic foot microwave is genuinely usable
    Cons
  • Microwave and oven cannot run full power simultaneously
  • Combo installation is more complex than a single unit
  • Pricier than standalone single wall ovens with similar oven specs
  • Touch controls can be slow to respond when oven is very hot

Our verdict

The best combination wall oven for kitchens that need both

If you need both a wall oven and a microwave in a single 30" cutout, the GE Profile PT7800SHSS is one of the best options available. The oven portion is genuinely capable, the microwave is more than adequate, and the overall build quality reflects GE Profile's reliable reputation.

The limitations are inherent to the combo format. Simultaneous full-power use of both units is restricted, and the overall price is higher than buying a standalone single wall oven. For kitchens where space is the constraint, those trade-offs are worth making.

Frequently asked questions

Can you use the microwave and oven at the same time?
You can run both simultaneously, but with some limitations. The oven and microwave share a circuit, so running both at full power is not possible. In practice, low-power microwave use while the oven is active works fine for most situations, like softening butter while something is baking.
What cutout size does it require?
The PT7800SHSS requires a 30" wide by approximately 50" tall cutout to fit both the oven and microwave sections. Exact dimensions are in GE's installation guide, and confirming your cutout size before purchasing is important.
Is the true convection worth it compared to standard convection?
Yes, noticeably. True convection uses a dedicated heating element around the fan to distribute genuinely even heat, rather than just circulating air from a single element. For baking especially, the difference in evenness is real and consistent.
