User Suggested Solutions

  1. Inspect the microwave for internal damage. If the bottom is misaligned, carefully realign it and check that all components are secure. For a cracked door, consider replacing it entirely as it may pose a safety risk. For burn holes, replace the waveguide and ensure no metallic materials are used inside the microwave.

  2. If the door is cracked, it is advisable to replace the entire door assembly to ensure safety. This involves removing the old door and installing a new one, which can typically be done by following the manufacturer's instructions.

  3. For burn holes, if the waveguide is damaged, purchase a replacement part and follow the manufacturer's instructions to install it, ensuring all power is disconnected before beginning work.
