Check the size rows. For the black GCST10A1WBB^*, the seller says 20.59 × 15.59 × 12.52 in, while GE's sheet for the same family says 20.6 × 16.6 × 11 7/8 in. Both GE 4-in-1 listings also quote 13.98 × 9.49 × 13.23 in, far too small for this body. Plan with GE's figures.

What is the GCST10A1 like on the counter?

GE's product sheet gives 1,050 W and 1.0 cu ft, a stainless crisper pan for air fry, a child lock, plus auto and time defrost. The owner's manual adds what listings leave out:

• Air fry setup. Always use the crispy pan on top of the tall rack. Manual mode accepts 300 to 425°F, and the oven prompts you to flip. Menu mode has nine foods, each with a set serving size, such as 8 oz of fries.
• Racks and microwave. GE says not to use the racks when microwave cooking. Our page on metal and foil explains why this depends on mode and model.
• Space around it. GE recommends 3 in on each side, 3 in on top and 1 in at the rear, with nothing blocking the bottom. Keep the door front at least 3 in from the counter edge. See our clearance guide for how other brands differ.
• Circuit. GE's support page asks for a 120 V, individual, properly grounded branch circuit with a 15 or 20 amp breaker or time-delay fuse. Read our page on circuits and amps too.
• Not for cabinets as it comes. The manual says it is not meant to be built into a cabinet without a GE Appliances installation accessory.

What about the retired JES1109RRSS?

Many searches still name this model, and it still turns up in older articles. GE's page says it is no longer made. Its stated size matches the GCST10A1, but we found nothing from GE calling one the successor. So don't assume every detail carries over, and buy by model number. If you own one, GE still links the owner's manual from that page. Our guide to finding your manual covers the rest.

What about the GE Profile over the range?

The GE Profile PVM9179^* is a 1.7 cu ft over-the-range unit with air fry and 950 W (IEC-705 procedure), says GE's sheet. It has a three-speed, 300 CFM vent fan (CFM is how much air it moves). It is 29 7/8 in wide, needs a 66 in minimum mounting height and ties into venting or a recirculating filter. Many people buy this type from a dealer or big-box store, since it has to be mounted and vented. GE's page for the PVM9179SRSS says it is no longer made, and our price lookup returned nothing for this listing, so ask about stock, condition and warranty. See over-the-range microwaves.

What are the strengths and weak spots?

The GCST10A1 manual states a one-year warranty on the oven and names GE Appliances, a Haier company, as the warrantor. It lists the tall rack, short rack and crispy pan as parts of the oven. Ask GE or a dealer about replacements, and check the seller's terms too.
