Question about Honeywell HW628 Window Mount Fan

1 Answer

Loud screeching sound from window fan.

How do I oil the motors of a Honeywell twin window fan? Mine have started making loud screeching sounds not unlike a wild banshee. It can be unnerving when you're not expecting to hear something like that....especially in the middle of the night. My friend thinks it needs an oil job. But I'm not handy at taking things like this apart without it meeting it's demise. Any advise at this point would be most appreciated.

There are two bearings in most motors.  One is at the base of the fan blade where the shaft goes into the motor.  Try lubricating this with a small amount of household oil.  If your lucky, this will stop the problem.  If not, the bearings have worn and the unit will need replacing.

Why is there delayed start & screeching?


The motor needs to be oiled. There are places to add oil on the ends of the motor. There may be a start capacitor that needs replaced too.

Could be the fan motor's bearings. Try turning the fan by hand to see if spins freely or is tight. If it's tight you can try oiling it but that may not work for long.

Fridge making loud screeching sounds


Generally, in my experience, the loud screeching is caused by one of the fan motors or fan blades. There is a fan inside the cabinet (possiblle two, one on the freezer and one on the refrigerator side). Also, there is a fan underneath the unit near the compressor (probably in the back).

If the screeching is coming from underneath then pull the unit out from the wall and remove the cardboard cover at the bottom back. Now turn the unit on and check for where the screeching is coming from.

If it is the fan blade (hitting something) or the motor, you can remove these and replace them easily. UNPLUG THE REFRIGERATOR BEFORE TOUCHING ANYTHING UNDERNEATH THE BACK OF THE REFRIGERATOR.)

Good Luck!

Outside fan does not spin and a loud screeching sound coming from


Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else

Loud screeching noise coming from the unit.


A screeching or squealing noise usually comes from the fan motor. There may be an oil port and you can buy a small telescoping oil bottle at a super hardware store or an a/c supply house. Before putting in he oil, remember to TURN OFF THE POWER TO THE UNIT and only use a light squeeze on the bottle - over oiling will cause a mess inside the motor. It may be a sealed motor and no oil ports. In either case, budget for a new motor as if it's to the squealing stage, the bearings are already damaged and it's a just matter of time before before the motor bearings fail. If possible, get oil on the bearings ASAP - and use the proper lightweight oil for made for this application.

Fan motor has loud screech.


Check for oil ports on motor. Usually red or yelloe plug in caps. No more than 20 drops of oil. I usually use sewing machine oil.

Fan making loud noise like it needs oiled


Most of the fan motors can be oiled. You will have the slide the ac forward and remove it from the case to access it. You will find yellow pull pins on each end of the motor, a lite drop or two is all that is needed.
