Lonestarbill for Model Number KBMS1454s My cover too melted in the center. It looks like something splattered on to it and heated up enough to melt it. On the other hand, If it is the magnatron failing, how would I know that?
Answer Hi Lonestar. Tricky one, If the magnetron is still heating well, then is should be OK. If the inlet cover melted then it is safe to assume the heat was at a higher setting and the heating occured towards the interior top area. This part # is W11087199. Thank you. Read More...
