My microwave is sweating

No. This is usually a sign of poor venting or air flow. It's possible that the coling fan is not circulating the air properly due to a problem with it or maybe the air vents are blocked. Also, there needs to be a couple of inches around a countertop model on all sides - especially the back - to ensure air flow. Look for buildup on the back vent grille. You can listen for the fan to be running and feel the air flow while it's running. If it's weak or not there, it needs inspection / service. A lack of air flow can cause the magnetron to overheat and be damaged. If this is a built-in model also check your air filter, air duct work and outdoor vent flap. Write back if you still have trouble.
