My Microwave Is Making Popping Noises Or Arcing. What Should I Do?

Last Update date : 2018.01.24

Popping or Cracking Noises in Microwaves

Popping or cracking noises can be caused by the following:

   • The food item you're cooking in the microwave. Dense foods or foods high in fat content can cause more noise. Covering foods and piercing the skin of potatoes and other vegetables will help reduce this.

   • Food spills can also cause popping noises. Clean up spills in the microwave as soon as they occur.

   • Operating the microwave empty can also cause popping and can damage the interior. Always have something in the microwave when you run it.

   • Using metal or metal-trimmed cooking utensils causes arcing in a microwave along with popping or crackling sounds.

   • If you are using the metal cooking rack, having the rack installed improperly can cause popping or crackling. Make sure the rack is firmly in place and not upside down.


   • If the popping noise is electrical or mechanical in sound, or the microwave appears to have burn marks inside, the oven requires service. Immediately discontinue usage.

   • If the oven arcs, sparks, or crackles while in use, and there is no food residue present and you are using only microwave-safe cookware, the oven requires service. Immediately discontinue usage.

If your microwave oven requires service, please contact us (Canadian customers only).
