GE GCST16S1W1WW Microwave Arcing During Use
Stop the GE GCST16S1W1WW as soon as you see arcing, press Cancel/Off once if the controls respond, and leave it out of service if the sparks recur or leave any scorch, hole, blister, smoke, burning odour, door damage, or electrical fault. After it is cool and disconnected from a safe dry position, remove only an obvious metal item, foil, metallic-trim dish, twist tie, or contaminated paper product from the cavity.

GE Spacemaker 1800XL Microwave Arcing at the Waveguide: Do Not Reconnect After a Magnetron Change
No—do not reconnect or run this GE Spacemaker 1800XL after arcing from the magnetron antenna toward the waveguide, even if the magnetron was replaced with one that appears identical. “Spacemaker 1800XL” is a family description, not a complete model number; GE's official owner centers show different JVM models under the XL1800 name and route each one to its own manual.
