Ac makes a grinding noise...does it have to be lubricated? my neigbor below complains that the noise keeps her up all night. need your help. thank you,

The shaft that the solenoid pushes the gear up needs lubrication. If it's been grinding too long, the bearing in the starter is worn letting the armature to rub on the field frame. Might be time for a starter motor.

Look at the universal joints on the 2 ends of the drive shaft. The hubs may have dried up and wore out you might be grinding metal. If so, you need to replace the universal joints before the drive shaft falls out.

There are many possibilities that can cause car to make noise.

It's actually from where the noise is coming from. Front end or rear end. From engine area or from inside the steering or from brakes.

There is N-number of possibilities for the car to make grinding noise or any other kind of noise.

The noise could be your drum rollers need lubricant or replacement.
When the drum rollers get flat spots on them they will make a bumping/thumping type of noise.
The grinding noise sounds to me like the drum rollers are in need of lubrication.

pls try to lubricate it if it got oiling port as soon as possible. if no port you may change bearing before the damaging motor . also if this type of motor does not have bearings better to change it

It is passable the grinding noise is coming from one of the toner cartridges in the printer.

Check for any toner cartridges which are stiff or difficult to turn by hand
Replace and refilled toners or compatible toners with original manufactures toners.
If you have alternative toners available replace each toner in turn to see if the cause can be identified to a particular toner.

This sounds like the stirrer. If it sticks or stops, the microwaves can damage or destroy it. You may have a bad stirrer or magnetron. There is an important bulletin that covers these problems. To see if yours is covered, see: http://207.234.249.73/mwd/ge_mw_mag_kit_bulletin.pdf If you need more help, please follow-up.
