John K. for Model Number JVM1340BW003 do you have a turn table coupler for this model? If it has a carbon deposit on the underside would that cause arching?
Answer John, The turn table coupler for the model number you supplied is WB06X10138 / WB06X10138 . The part is in stock and available at this time. As for "arcing" in the microwave, there is no metal of any sort involved in the coupler, if there was a "carbon" deposit, it wouldn't arc anyway. the carbon fiber would absorb the microwaves, not reject them. You'll need to look for bare metal, scrapes and gauges in the painted surface of the cavity, and or metal shavings etc. on the bottom of the microwave and under the turn table. Read More...
