Of course it had to be one of the range hood combo units. Was practically new when I got house. All of the sudden it just stopped cooking. Lights up, runs, I can hear the buzz when the magnetron turns on, but won't cook anything. Thankfully still had my old microwave that still works fine after 20+ years to finish making dinner. Lowe's was having Black Friday sales, so I picked up one that fits perfectly and didn't involve making any new holes.
