The thing is, the superior way to reheat something would usually be a lower power level. But not the standard "turn on - turn off" cycle that most microwaves do. Actual lower intensity microwaves. You need an inverter for that. The food would heat more evenly, which is especially useful for things like butter that are prone to splattering.

I bought a microwave a couple of months ago, and found it impossible to determine which if any of the cheaper ones were inverter microwaves, or if they just used duty cycle power control. I assume that distinction is only made with higher-end microwaves. In the end I went with the model that looked to have the simplest design and least things to break.

I migrated our house to a "commercial" variant of the microwave oven [1] as I was tired of all the over-engineering and annoying patterns in modern microwaves. This microwave has exactly UI element other than the door - a digital dial that goes from 10s-6m. No start/cancel, no power level, no defrost, no program mode. I don't "cook" using the oven, only reheat or very rarely heat/boil small quantities of water. The m…

We recently got rid of a four year old microwave where the magnetron turned on spontaneously and silently when the door was closed, runaway heating the box. Control panel, lights, turntable, fan, everything is idle. Manufacturer didn't consider this an interesting defect and refused to swap out-of-warranty. The lack of give-a-shit in appliances is becoming apparent.

It's so limited without a power level feature. It needs to be able to cycle power to heat food evenly.

It does heat food as evenly (possibly more evenly) than my other microwaves.

What was the model? I recently encountered something similar with a GE over-the-counter microwave. One day it stayed on after opening the door. I replaced the control module and the board in it looks exactly like the one in the OP photo (Midea with all of the same components), which leads me to think the fault is the same as the one described in the post.
