I have sparking under the coupler ap2016748. Could replacement of this coupler stop the problem ?
Answer Hi Thomas. If there is bare metal scrapped off under this coupler part # WB06X10138, you will need to use microwave white paint part # TJ98QBP0302. Inspect the turntable motor leads to see if they are pinched , shorting the motor part # WB26X181. Correct all wiring conditions back to the clean and tight conditions. Thank You.
