Question about GE Spacemaker JVM1640SJ Microwave Oven
When the unit is turned on, everything works great, but the unit makes loud ticking sounds?
A LOUD ticking sound could very well be a High Voltage Arc. This is usually caused by a breakdown of insulation on High Voltage Wires, or components. It can also be arcing between the door frame and the cavity. Usually where the bottom of the cavity floor meets the door frame. Indication of this will be small areas on the door where it looks like the paint has been chipped off, but if you look close you will see it is small burned marks. Another area is the Splatter Shield located inside and at the top. It looks like a Plastic Cover. It is not plastic, but a fiber material. Grease, and food will get trapped on and under this Splatter Shield. Over a period of time the grease and food particles will break down from being cooked over and over again. They will then form Carbon. Which will Arc when Microwaves are present. Remove Push-Pins holding Splatter Shield. Clean by washing with dish detergent . If burned (arc) spots are still present after washing, replace Splatter Shield or arcing will continue. Once Carbon has burned through, it will continue to burn.
