Does that fuse work for only the under light and fan? Where is it's location on the microwave?
Answer Hello Jean. No, the fuse is for the whole unit. If just the lights and fan does not work, then it sounds like the control board is bad and will need to be replaced. Hope this helps.
This is only a fuse for the fan and lights above the stove. Not a heating fuse.
Answer Jean, part number WB27X7 is the only fuse the manufacturer offers for your appliance. There is however, a diode part number WB27X1160.
