Alan T Concord , CA April 19, 2020 Appliance: Model GE JE2160SF01 After replacing fuse HV diode and all 4 door switches, cup of water was still not getting hot enough. Original HV Diode (from another vendor) was suspect and packaging was previously opened. Ordered new diode and magnetron on Sat and it arrived the following Tues afternoon. The microwave was 15+ years old, built-in and saw a lot of use from prior homeowner. Installed new diode and magnetron within 15 minutes, tested it and reinstalled in cabinets with face plate.
