Anonymous users2024-01-24Some time ago, the fault has shown that the motor is short of oil at both ends (it is unlikely that the capacitor is broken from the picture), the motor can be used with a multimeter resistance, the resistance of the blue line and the brown wire R1, the resistance of the purple wire and the blue wire R2, the resistance of the blue wire and the purple wire R3, R1 + R2 = R3This shows that the motor is good, just oil.

The closing of the fan blade is to turn off the power supply, stop the blowing and then close by the weight of the blade, can not be closed must be resistance? A little oil can be dropped on its hinge to make the opening and closing flexible.
Check whether the surface of the coil has abnormal performance, use a multimeter to detect the grounding resistance, beyond the range there may be problems, moisture or insulation damage, use the meter to measure the coil resistance, do not pass to indicate that there is a breakpoint, the humidity in the bathroom is relatively large, may be mildew.
The effect of artificial ventilation is better. Exhaust fans can be installed on the ceiling, walls and windows of the toilet to discharge the dirty air directly to the ventilation duct or outside to achieve the purpose of ventilation in the bathroom. For houses that do not have vents in the building, you can install a set of ventilation ducts to open to the outside. >>>More
1. Disassemble all the downstairs bathroom ceiling, there are leaking water stains on the floor, you can conclude that it is your bathroom leakage, if the dry top, it must have nothing to do with your home. I hope my answer can help you.
1. Find the leakage point and where the water comes from. Otherwise, you block one point, and the second point leaks.
