Just switch the power cord of the capacitor from one end of the capacitor to the other. Or install a SPDT switch (which you can find at a hardware store) and you can easily change the steering of the ventilator. The wiring diagram is as follows:
It doesn't exhaust the air, it will pump the outside air into the kitchen. >>>More
Probably not, the heating exhaust fan in the bathroom is on the bath bomb, and the ventilation exhaust fan should be installed on the wall to pump the air out of the bathroom.
Check whether the capacitors of your power supply and the power supply close to each other have exploded, the capacitors are standing vertically on the board one by one, and the explosion means that the top is flat and has become a little protruding, and the protrusion is bursting, and the capacitor can continue to be used but is unstable.
There are many possibilities for loud noise, one is the check valve, the other is that the smoke pipe is too long and the internal pressure is too large, and there is the loose fan blade and the bending of the bearing, I don't know which one you belong to?
