Pros

•The oven features 3 sellean heavy-duty racks configurable in 6 positions, offering flexible cooking setups.
•Easy to clean overall, especially with the selleaning oven feature.
•Impressive and reliable quality noted by many users.
•Glass touch electronic controls paired with a dial allow for quick and easy adjustments.
•Generally meets or exceeds performance expectations for both the oven and microwave.

Cons

•The selleaning function can trigger a persistent loud clicking noise after cleaning cycles.
•There is a recurring mechanical fault linked to the selleaning lock mechanism, which may require warranty service but can reoccur.
•Manufacturer’s customer support has been reported as unhelpful, inconsistent, and sometimes charges for labor despite ongoing warranty issues.
•Installation is complicated, with poor design—especially no proper support or holding points to lift the bottom oven unit.
•The manual lacks detailed, producpecific instructions.
•Disconnecting and reconnecting microwave wiring during installation is difficult due to the unit’s depth and complexity.
•The microwave can be notably deep, making cleaning the back area cumbersome.
•Oven racks are reported to be difficult to slide smoothly, with some buyers replacing them for better functionality.
•Microwave reliability concerns surfaced as some users experienced failures shortly after the warranty expired, leading to diminished brand trust.

Bottom Line

The GE JT3800SHSS Electric Combination Wall Oven offers a solid combination of microwave and oven capabilities with strong performance and flexible rack options. However, prospective buyers should be aware of potential reliability issues related to the self-cleaning feature and mechanical lock, plus challenging installation and microwave maintenance due to design shortcomings. If you prioritize smoother installation and longer-term reliability, you might want to weigh those concerns carefully. For an alternative, exploring wall ovens with simpler installation or a standalone microwave might be worthwhile, but this unit remains a good choice if you value integrated convenience and strong oven functionality.
