An H4900B with a failed convection element is a confusing machine to live with, because it still heats – just not evenly, and not in the mode you selected. Owners describe it as the oven cooking badly rather than as a broken element. Checking which heating modes work and which do not, before a technician arrives, narrows this considerably, and it is something anyone can do with a thermometer and ten minutes.
