Whirlpool/Heil Quaker recall

I know some of these were recalled due to burner problems or something of the sort. Does anyone have any info on this?

Model # NDGK075AF01
Serial # H537 51272

Any help is always appreciated!!

I don’t think this was one of the recalled. The recall I remember was for ones made by Consolidated and sold by various other companies. This one
Model # NDGK075AF01 was not on that list.
