Terry for Model Number JVM1540DM4WW What is the part number for the smart board for this unit? This GE microwave does not respond to any button. The message panel does not light. The fan does not come on. Everything stopped at once with no warning. All functions worked fine before unit quit. Power source is ok. Circuit breaker is on and ok. I noticed what looked like a connection failure at the upper left corner of the display. The clear plastic housing of the display is darkened on the inside by a black 3/8" diameter area that extends around the side. It looks to me like the dark area was caused by heat at a failed electrical connection or possibly by heat during assembly. The complete lack of the microwave' function accompanied by this dark area in the display of the smart board causes me to think that the smart board may be the problem. Am I correct? If I am, please send me the part number for the smart board for a GE model JVM1540DM4ww microwave. Thanks for any answer that you send me. Terry
Answer Terry, The smartboard on this unit will be WB27X10931 but would suggest testing the fuse in the unit as it would be the most likely issue followed by the control board. Read More... Answered by AppliancePartsPros.com | Thursday, February 20, 2020
