AmTec Services Posted August 21, 2010 Author Share Posted August 21, 2010 Thanks for the reply. Is the power xformer built into the smart board? Is there a specific test for the board, other than visual?.................AmTec:? Link to comment Share on other sites More sharing options...
appl.tech.29501 Posted August 21, 2010 Share Posted August 21, 2010 That Mod # should be... JVM1540SM1SSYes the transformer is attached to the board as seen belowYou need to verify that the board is getting 120 VAC via the diagram. If the board has 120 V and you have no display then the board is bad.If I remember correctly the hot wire is broken by a cavity thermostat..I have seen a bad connection at that point a few times.Your inline fuse it mounted to the Noise Filter assembly as seen below Link to comment Share on other sites More sharing options...

AmTec Services Posted August 31, 2010 Author Share Posted August 31, 2010 Got to look @ this micro. Found the reson for no display was the MGT thermal cut out was open and no power to board.Will pick up and replace. I have the paperwork from inside the unit. Has a nice wiring diagram and trouble shooting flow chart. Would it be helpful if I scaned and uploaded same?..............AmTec Link to comment Share on other sites More sharing options...
