Frigidaire Microwave Making a Popping Noise
If your Frigidaire microwave is making a popping sound, it is most likely because of metal. If you put a metal plate in a microwave, it could cause it to spark and make a popping noise. Inspect the plate you placed in the microwave for any metal substances. If you notice any, take it out of the microwave.
However, if your plate isn’t metal, you may be hearing the popping sound if your plate of food isn’t covered. When you leave your food open in a microwave, the oil or water in it could be entering the inner parts of the microwave, thus creating a popping noise. Cover your plate of food while cooking in the microwave to prevent this.
