It is not safe to use a microwave with the door open, even slightly. Microwave ovens are designed to operate with the door securely closed. The microwave door is equipped with special safety switches that are designed to prevent the microwave from producing microwaves when the door is open.
Using the microwave with the door open, even just a little, can lead to several safety hazards:
Exposure to Microwaves: Microwaves are a form of electromagnetic radiation that can be harmful to humans. If the door is open, microwaves can escape and potentially cause harm to anyone nearby.
Fire Hazard: If the door is open while the microwave is operating, there is a risk of food particles or liquids spilling onto the microwave's internal components, causing a fire hazard.
Damage to the Microwave: Operating the microwave with the door open can cause internal damage to the microwave's components, leading to malfunctions or rendering the microwave inoperable.
Voiding Warranty and Insurance: Using the microwave with the door open violates safety guidelines, and any damages or injuries resulting from such use may not be covered by the warranty or insurance.
To ensure safe and proper operation, always keep the microwave door securely closed when using the appliance. If you notice any issues with the door not closing properly or problems with the safety switches, immediately stop using the microwave and contact the manufacturer or a qualified technician for inspection and repairs.
