That was the reputation of LG, 5-10 years ago. And probably a good reason not to run one on dirty power.
Just because my Fuitsu never minded running on a cheap genset doesn't mean it was safe. But they do appear to be more robust than LG.
My current setup, if I fry the board in my condenser, I can always take out the $50 Rheem board and put the original Goodman board back in. Frying the board in the furnace might be a bit more expensive, but I got through a five day ice storm on a 1980s Coleman generator, so it seems safe enough.

My 3 LG units all want 30A 220V breakers. No idea if they reach even close to 30A. Note that one unit has fried 2 main circuit boards at like $400 a pop. They seem very sensitive to spikes,
