If you have dropped a new microwave on the back corner, it's important to assess the extent of the damage before determining if it is safe to use. Here are a few factors to consider:
External damage: Check the external casing of the microwave for any visible cracks or deformities. If there are minor cosmetic damages but the structural integrity of the microwave is not compromised, it may still be safe to use.
Door and seal: Ensure that the microwave's door and seal are intact and functioning properly. The door should close securely and the seal should create an airtight seal when the microwave is in use. Any damage to the door or seal could pose safety risks, and the microwave should not be used in such cases.
Functionality: Test the microwave by running a short heating cycle with a small amount of water or a microwave-safe item. Pay attention to any unusual noises, sparks, or malfunctioning controls. If the microwave operates normally and heats food effectively, it is a good indication that it is safe to use.
Safety concerns: If dropping the microwave has caused significant internal damage or compromised its safety mechanisms, it is advisable not to use it. Internal damage could lead to electrical hazards or the microwave not working properly.
In any case, if you have any doubts or concerns about the safety of a microwave that has been dropped, it is best to consult the manufacturer's instructions or contact their customer support for guidance. They will be able to provide specific advice based on the make and model of your microwave.
