I have a Whirlpool Microwave /Range Hood combo, model # MH3184XPQ-4.Was replacing the lightbulbs under the hood and one broke while removing it. The bulb base then shorted against the socket and now the whole unit is dead.Did not trigger the breaker in the fuse box , so the short has affected the whole control board. Is their a replaceable fuse on the mother board that I can look at replacing or am I at risk of having fried the whole mother board completely? I recently replaced a whole mother board in my whirlpool double oven. I am competent enough to go this route if needed but I was just curious about the possibility of trying fuse or component replacement before going the whole board route?
