Hi I am Armando and I have a LG AC Mo # LSN180CE and I start to hear a bearing rattle noice right after the compressor, seems to me like it. The evaporator is like 20' o 25' away inside of the room, the compressor unit is outside, can you help me?


First of all confirm where the sound comes from whether from Indoor or out door. If from indoor, the blower bearing worn out/ blower wheel broken.
If from out door, fan blade broken (replace fan blade)/compressor internal sound(replace compressor)/compressor seating bush worn out.(replace new bushes).

We have a split system. When both units are on there is a high pitch sound coming out of the one unit.


Please check the sound comes from indoor, blower wheel may be broken or fan motor seating bush worn out. Rectify. If it's from out door, fan blade may be broken. Replace it. If interna sound from compressor, you have to replace compressor only.

I have a kenmore elite bottom freezer refrigerator (trio). When the freezer door is closed a rapid clicking/grinding noise has started. When I open the door, it stops. When I close the light switch at the top of the freezer, the noise starts again


I've heard similar refrigerator noises like yours before. Sounds like the evaporator fan motor, located in the freezer and runs only when the door is closed, is being obstructed, possibly by ice, possibly by some wiring or even a food item. You could have a defrost problem, but you dont mention any refrigerator or freezer temperature problem, so that is likely not it. It is also possible the evaporator fan motor itself is out of balance. If you remove the back wall of the freezer, you will be able to see if there is something obstructing the fan blade, if the motor or shaft is out of balance, when you close the door light switch, check the balance of the shaft, it should not have any wobble at all, in fact, if the fan blade is not attached, you should not be able to tell by looking at the motor shaft if the motor is running or not. Also, just happened to think, if one of the fan blades is even partially broken off, that will cause the motor to be out of balance. But if one of these blades is broken, it was broken by something else, either ice or something, and you may have to find the cause of that, otherwise it may happen again.

Noise from fridge when doors are closed.


There is a good chance this is the culprit.

Servicing the Evaporator Fan

In some cases, a faulty thermostat may not be the cause of a warm refrigerator or freezer. A warm box may also be caused by a defective fan, a blocked fan, or broken or bent fan blades. If the blades are jammed, try to free them. If they're bent, straighten them with pliers. If this doesn't solve the problem, call a professional service person.

On some refrigerators, the door switch operates the evaporator fan. If the fan seems to be malfunctioning, the door switch could be faulty. Test the switch as detailed in the last page, and replace it if necessary.

Good Luck! Buddy777
