It's annoying to make a squeaky sound on the lower right of the hook! Some people on the Internet say it is an indoor fan. The left bearing seat of the impeller is short of oil! How do you add oil?!
The motor is on the right, the left is oily bearings, motor bearings refueling is not an easy task
Just the usual lube. How long have you had the air-conditioner?
Do not add any oil, the problem may be that the machine is not installed smoothly, or there is a break in the wind wheel partition, there is no slightest relationship with the motor, the wind wheel with a square ruler to test whether there is a slight deformation! Air conditioning repair six or seven years have not encountered a fan of lack of oil, there is no such thing what oil warehouse customer service!
