The solutions for the buzzing noise depend on the cause of the problem. Here are some steps you can take to diagnose and fix the issue:

Unplug the Presto Heat Dish and use a soft brush to gently clean the fan blades. You can also check if the fan is balanced by spinning it with your finger. If it wobbles, it might need balancing.
  2. Check for Loose Components: Inspect the internal components of the Presto Heat Dish for any loose screws or wires. Tighten any loose screws and reconnect any wires that have come loose. If you find any faulty components, you might need to replace them. You can usually find replacement parts online.
  3. Prevent Overheating: To prevent the Presto Heat Dish from overheating, ensure that you're using it correctly and not leaving it unattended. Also, make sure that the dish you're heating isn't too large or small for the appliance. If the dish is too large, it can block the fan and cause the Presto Heat Dish to overheat.
