As someone who sold appliances and did kitchen design for about 10 years I would always to my best to talk customers out of a combo unit like this. Most ovens will far outlast the built in microwaves in these types of units. Better to get two separate units (a microwave plus a trim kit or if you have the space/power consider a speed cook, air fryer, microwave combo).

Looked at this a few years ago. Ultimately decided against it. The reliability gave us pause. And with the combo approach, if one part breaks, you get the thrill of having to replace both. I can see why the manufacturer likes it.

Instead just bought a Whirlpool wall oven and a Panasonic microwave with a wall-mounting kit. Neither was particularly expensive. I think we spent 600-ish on an open-box oven from Best Buy and about 200 on the microwave. We did have to change the wall openings a bit, but it wasn't too hard. We are much more satisfied with this setup.

Good luck. Often LG, Samsung, etc deny fixing these and other appliances due to no replacement parts. This isn't a 10yr old Kenmore.
Don't know when this appliance came out, but California law (went into effect on 2024) requires manufacturers to make parts, tools, and documentation available to consumers for seven years after the production of a device priced over $100.

I have a 10+ year old KitchenAid Wall Oven Microwave combo which was part of the "upgraded" kitchen when we bought our home. It's been good except earlier in the year when the microwave door malfunctioned. Thankfully, home appliance warranty covered it with a $100 deductible.

Overall, good experience as we were given a choice of either Whirlpool or KitchenAid for the appliance upgrade (Oven, Microwave, Stove & Range Hood) and we were recommended to pick KitchenAid. However, can't guarantee if the newer models are as robust as the old ones.

Did something similar 5 years ago, and haven't had any problems with either of them. Both are GE, but entirely separate items instead of a combo. Also had to use the trim kit for the microwave.

Was going to buy it until I read the reviews and everyone is complaining about having to replace it multiple times due to the microwave dying. I think there's a reason it's being clearanced out.

Quote from FlyNHi :
This is getting to be more common even though Panasonic is a good maker (they make a lot of brand under license so does LG, Panasonic etc) there have been strings of bad magnetrons(that the supplier issue and most are made for them in China) out there across the board. Magnetrons are available and i change them out all the time. Its not a fix for everyone as there is a couple hours to remove unit. Properly open acess then ensure its discharged then (test) Install new and i always change the fusesable link. I just had a LG at 1 year 3 days yet the client called it in in the 12 month and they refused warrranty 1 year. This whole magentron issue is a problem from the suppliers making junk Major manufacturers of microwave magnetrons for consumer appliances include Sharp, Panasonic, and LG, with many units produced in China by Midea. For industrial, medical, and defense applications, specialized manufacturers like CPI Electron Device Business, Hitachi, and Richardson Electronics are industry leaders.
Are the magnetrons model specific, or is it relatively easy to find something compatible with similar specs?

Have a 15 year old Kitchenaid Superba builtin combo. Can't say it's been problem free, but with a bit of know how and willing to DIY, we've kept it going without needing to replace the whole thing. We replaced the micro door switch*, lamp, god awful microwave door torsion springs at least half a dozen times or more before giving up on them, and magnetron twice. Oven had a couple issues, like the locking mechanism getting stuck closed, but has been more the reliable of the two.

*weird issue turned out to be the door wasn't fully closed (due to it being spread wide a bit after repeated opening and re-installing screws in plastic in order to replace stupid torsion springs in the door. Because the inner surface wasn't 100% down, it was keeping the safety switches from engaging and the micro assumed the door was still open.

Magnetrons are pretty similar from one residential micro to the next... just need the configuration and power range the same. Regardless of the part number, it'll likely be replaceable with any number of similar ones with that same ID (2M240H, etc) Problem is actually figuring the designator ID number when manufacturer and documentation usually only give you their own internal part numbers. Best bet is to search part sources like parts websites and even ebay and amazon for generic replacements for your model and try to glean what part number they'll be sending.

I hope the Whirlpool doesn't have a touchscreen. There are a lot of reports of these touchscreens failing at 2 to 3 years. Ours failed at 4 years and we're looking for solutions.
