Beijing Sanyo Air Conditioning Repair Technical Summary on September 9, 2011.
The cooling effect of the Sanyo air conditioner is not good, and there is no obvious change in wind speed.
Analysis and maintenance: After carefully checking, the power voltage is 380V, the current is 9A, and the low-pressure pressure is 0.5MPa, all of which are normal. However, the outlet temperature is too high. The initial judgment is that the fault is caused by a small circulation airflow. Upon checking the outlet, it was found that the airflow was very small. Further checks on the fan and fan capacitor showed they were in good condition. When adjusting the wind speed, there was an obvious sound of the fan relay (high, medium, low) engaging, but there was no significant change in wind speed. It was determined that the fault was caused by a dirty clogged filter net and evaporator. After opening the indoor unit panel, it was found that there were many fabric fibers stuck to the back of the evaporator, and there was frost on the evaporator. After cleaning the indoor unit evaporator, the Beijing Sanyo air conditioning repair phone number was called, the airflow returned to normal, and the cooling function worked properly.
