The fan is making a "scratching" noise.


Hi steffmarin...
The scratching noise is one of two problems.
1.noisy fan bearings, cannot be lubricated, must be replaced (big job), or replace fan....
2. Plastic/rubber bearing up near the ceiling...the fan will be connected to it.
Sometimes when they get dry they get noisy.
You can spray the plastic/rubber bearing with a little WD-40 and it will hold the noise quite for a while...be sure to "wiggle" the fan around after spraying to distribute the WD-40) evenly.
If your noise problem is this then problem solved.
Please take time to rate me

My LG ice maker fan is making a really loud noise right after the water stops going in


Hello, Self-defrosting refrigerators use a circulating fan to move air through the freezer and refrigerator compartment. This fan runs when ever the unit is cooling. The fan is located in the freezer, as follows:
  • If the freezer is on top, the fan is on the back wall,near the top or bottom, in the center of the freezer.
  • If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.
  • If the freezer is on the left, the fan is on the back wall, half way up or near the top.
Overtime the fan may become noisy, usually making a chirping or squealing sound, though it may make a loud groaning noise instead.
To find out if the fan is causing the noise,just open the freezer door and push in any fan/light switches, if the noise is louder when the door is open, the evaporator fan motor is the cause. You can lubricate or repair this motor. You must replace it.
There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor(if self-defrosting), or the defrost timer (if self-defrosting).
Thanks

Hello there
Please follow these steps first ok
It's noisy Noise can come from these areas: The inside of the freezer The outside back of the refrigerator The bottom of the refrigerator The inside of the freezer Self-defrosting refrigerators use a circulating fan to move the air through the freezer and refrigerator compartments. This fan runs whenever the unit is cooling. The fan is located in the freezer, as follows: If the freezer is on top, the fan is on the back wall, near the top or bottom, in the center of the freezer. If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer. If the freezer is on the left, the fan is on the back wall, halfway up or near the top. Over time, the fan may become noisy--usually making a chirping or squealing sound, though it may make a loud groaning noise instead. To find out if the fan is causing the noise, just open the freezer door and push in any fan/light switches. If the noise is louder when the door is open, the evaporator fan motor is the cause. You can't lubricate or repair this motor. You must replace it. The outside back of the refrigerator There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor (if self-defrosting), or the defrost timer (if self-defrosting). The compressor is a football-sized case with no apparent moving parts. You can see it on the outside of the refrigerator at the back near the bottom. It is usually black and has black or copper-colored tubes and various colored wires attached to it. If the compressor is the device making noise, there is probably no repair that will reduce the noise. You will have to replace it--which can be quite costly. If the condenser fan is making noise, there may be a build-up of lint or other debris on the fan blade. The fan is located near the back of the machine, sometimes behind a thin panel. To clean it, first unplug the refrigerator, remove the thin panel, and use a soft bristle brush to clean it. If there is no lint build-up or debris on the blade, you will have to replace the motor. The defrost timer is often located at the bottom of the refrigerator it may make noise

sounds like you havent undone the transit bolts- theyre on the back of the machine, 2,3 4 maybe five quite large obvious bolts, around the drum but on the back. they are to keep the drum steady while in transit to stop the machine bouncing around in the van - you are unlikely to have damaged it - Undo these bolts - they should be mentioned in the manual-

HP LaserJet 3055 not powering on


Possible noisy laser unit or fan. Most likely the laser unit.

However,

You can pull the fuser out by pulling the rear door ALL THE WAY DOWN and remove 2 large screws and pull the rear cover off, then the the left and right small covers, the plastic guide on the bottom and 2 fuser screws. Be careful with the small wires on the right side.

You have to remove all covers to get to fan and laser which is a triangular shaped black box under the top cover.
