1. There are two spring clips on the microwave door. If it can't be opened, there may be something wrong with the spring, which can't rebound, resulting in the card stuck in the door. It is recommended not to open it forcibly to avoid damaging the card.
2. There is oil stain attached to the button, which will also invalidate the button. Tap the button to release it, and then press.
3. It is suggested to call the microwave oven after sale and let it check, repair or consult the opening method.
The microwave oven should always be kept clean. After disconnecting the power supply, wipe it with a damp cloth and neutral detergent. Do not rinse or let water flow into the electric appliances in the furnace. The shell of the microwave oven should also be wiped frequently to avoid oil pollution.
5, regularly check around the oven door and door lock. If there is any damage or poor closure, stop the machine for repair to prevent microwave leakage or door lock opening.
