1. Keep the production and use environment dry. Microwave equipment and electrical appliances are all made of metal. The humidity in the workshop is high and the surface will be relatively moist. When the power is turned on, the water vapor attached to the surface of the metal appliances can easily cause a short circuit. Especially during the rainy season in the south, preliminary dehumidification treatment is required.

2. According to the sanitation level of the on-site production and use environment, reasonably arrange dust cleaning work on equipment, electrical appliances, boxes, conveyor belts and other parts, especially air-cooled equipment, which requires special attention. Because if the magnetrons and transformers of microwave appliances are covered with thick dust, the heat dissipation effect will be poor, and they will easily burn out if they work for a long time.

3. Open the door of the microwave heating box regularly and clean the remaining debris inside the box to avoid a series of reactions caused by excessive accumulation.
