I see there are a few reviews where this microwave stops working after less than 2 years. This happened to me. I'd had it about 18 months when the sensor reheat stopped working. It would just shut off mid reheat. The other parts of the oven worked so we made due.  Yesterday, the microwave just shut down. It was also super hot inside especially by the fan cover. We checked the house fuse box and unplugged for a while. When we plugged back in, it was making a humming sound and got super hot again. It’s now unplugged.  Less than 2 years??  Very frustrating!!
