Peggy S Jefferson City , MO December 21, 2014 Appliance: General Electric Free Standing Microwave JE1860SH04 Ge Microwave Je1860sh04: Microwave arcing. How to replace Microwave Cover (Resin). After researching on the internet, I decided replacing the wave guide cover would be much cheaper than replacing the microwave. Plus I couldn't even find one that worked with the existing trim kit. Had a bit of difficulty removing the old cover, but the folks at Appliance Parts Pro answered my email question within 24 hours. I received the replacement part a day or so later. GREAT CUSTOMER SERVICE! Thanks! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
