Is thermal overload overheating of the heating element that is in direct contact with the water? Does it turn off briefly to protect the heating element from damage? If so, does that mean that the MCMHU may possibly not have that problem since the water is directly heated with micorwaves and not through conduction from direct contact with hot elements? Or do we know if the MCMHU uses both direct heating from microwaves AND conduction from hot elements?
