MSER2090S
LG MSER2090S Large NeoChef Repair
Most common issues on this model
- Door hinge and latch on a large cavity
- Smart Inverter output with a heavy load
- Glass touch panel response
- Sensor Cook accuracy
- Fit and ventilation if a trim kit is used
The MSER2090S is a NeoChef countertop microwave with a spacious 2.0 cu. ft. cavity. LG lists a Smart Inverter, Sensor Cook, SmoothTouch Glass Controls and an optional Trim Kit, the MK2030NST, sold separately. A second version, the MSER2090D, shares its page.
A 2.0 cu. ft. oven handles big dishes, so we check how the door, turntable and inverter cope with weight and long runs. We test the glass panel, run a heating check with a measured load, and try Sensor Cook. If the microwave sits in a trim kit, we also check that vents are clear, since a built-in fit can trap heat.
We confirm the version from the model and serial label before ordering. A written price is given first, and the repair has a 30-day warranty.

What is the trim kit for the MSER2090S?
LG lists the MK2030NST Trim Kit as a separate purchase for this microwave. If your oven is built in, we check that its vents have room and the fan runs normally.
Is the MSER2090D a different microwave?
It is listed as a second version of the same model. The label tells us which one you have, and we confirm it before we order any part.
Why does a large load heat unevenly?
The turntable, the inverter output and the door seal all affect it. We test each with a measured load and quote the repair that matches what we find.
