If your kitchen has a single 30" wall oven cutout and you need microwave functionality too, the GE Profile PT7800SHSS is one of the best solutions available. The oven portion is a full 5.0 cubic feet with true convection that produces genuinely even baking results. The 1.7 cubic foot microwave handles daily tasks well. The main limitation is inherent to the combo format: you can't run both at full power simultaneously. For space-constrained kitchens, those are trade-offs worth making. Rated 8.9/10.

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 performs like a standalone unit, and the microwave section is more capable than what you find in cheaper combo models.
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, not a reduced one. The microwave is 1.7 cubic feet, which handles everything from reheating leftovers to convection microwave cooking.
Convection baking results are consistently good. The dedicated convection element means temperature is more even than fan-only systems. We tested with multiple batches of cookies across different rack positions and found browning was even on the bottoms without over-browning on top. That's the most common failure of lesser convection ovens, and the PT7800SHSS avoids it. Roasted vegetables come out with genuine caramelization rather than steaming in their own moisture.
The microwave handles standard tasks well. Reheating is even without cold spots, which isn't guaranteed even on dedicated microwaves. The convection microwave mode, which uses both microwave energy and convection heat simultaneously, produces reasonable results for things like reheating pizza with a crispy bottom, or cooking small items quickly that benefit from some browning.
Using the microwave while the oven is preheating or running is possible, but it requires some coordination through the control panel. It's not as seamless as having two completely independent appliances on separate circuits. In practice, low-power microwave tasks while the oven runs work fine for most situations, softening butter, warming a cup of coffee, defrosting something small. Running the microwave at full power while the oven bakes is where the circuit sharing becomes noticeable.
The touch control panel is responsive in most situations. One thing worth knowing: the controls can be slow to respond when the oven has been running at very high temperatures for a while. It's not a consistent problem, but it happens. Switching between the oven and microwave functions is logical once you've used the panel a few times, though there's a brief learning curve compared to two completely separate units with independent controls.
GE Profile build quality is solid throughout. The stainless finish is even, the doors close with satisfying weight, and the control panel feels premium. The overall footprint fits a standard 30" cutout, though the height of the combined unit requires approximately 50 inches of vertical cabinet space. Confirming your cutout dimensions before purchasing is important.
Installation is more involved than a single wall oven. The combined unit is heavier, and the electrical requirements need to support both appliances on the same circuit. GE's installation guide covers the specifics, and professional installation is recommended if you're not experienced with appliance wiring. The cutout dimensions are precise, so measure twice before ordering.
The PT7800SHSS costs more than a comparable standalone single wall oven. That premium buys you a full-sized microwave in the same cutout, true convection baking, GE Profile build quality, and self-clean. For kitchens where adding a second cutout isn't practical or desired, the price is justified. For kitchens that could accommodate two separate units, a standalone wall oven plus a countertop microwave might deliver more flexibility for similar money.
Buy it if your kitchen has a single 30" wall oven cutout and you need microwave capability in the same space. It's also a strong pick for a kitchen renovation where you're deliberately choosing not to add a second cutout. The oven performance is genuinely good, and the microwave handles everyday tasks without feeling like an afterthought.
Skip it if your kitchen can accommodate two separate appliances and you'd benefit from running both at full power simultaneously. Two independent units give you more flexibility for large cooking sessions where you're using both the oven and microwave heavily at the same time. If space isn't the constraint, a dedicated wall oven like the Samsung Bespoke or GE Profile PFQ97H might be a better fit.
You can run both simultaneously, but with 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.
The PT7800SHSS requires a 30-inch wide by approximately 50-inch 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.
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.
The PT7800SHSS saves you a full appliance cutout, which matters a lot in kitchens that weren't designed for two separate units. The trade-off is that simultaneous full-power use of both is restricted. If your kitchen can accommodate two separate units and your budget allows, two standalone appliances give you more flexibility. If space is the constraint, this combo is one of the best solutions available.
The PT7800SHSS microwave section runs at 950 watts, which is standard for a built-in unit. It handles reheating and standard cooking tasks well. It's not the most powerful microwave available as a standalone unit, but for a built-in combo appliance it's more than adequate.
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 GE Profile's build quality is consistent throughout. The limitations are inherent to the combo format: simultaneous full-power use of both units is restricted, and the overall price is higher than a standalone single wall oven. For kitchens where space is the constraint, those are trade-offs worth making.
