Why Cosmo COS-12MWDSS-NH Microwave Oven is arcing?
- DDouglas BurnsJul 28, 2025
Arcing or sparking in your Cosmo Microwave Oven can occur if you are using materials that should be avoided in a microwave. Make sure to use only microwave-safe cookware. It can also happen if the oven is operated when empty, so avoid running it without food inside. Spilled food remains can also cause this issue; clean the cavity with a wet towel to resolve it.
