Search on Google by brandname and type of the Compressor , if there is no name of the importer of the product.
Sometimes there are if searched on Google on images of your compressor model some variants to see in other brand but with the same motor build ( a little suggestion "many compressors have the same FIAC motor) if its Italian brand but if its Chinese then maybe Aliexpress or Ebay to find the richt spare parts for it , modelname and the year of build serialnumber in some ways to get the right spares because of changes can be made in the time of an year .

The teardown information from rbrown67 was very accurate and easy to follow. It helped tremendously in tearing down my machine to replace the AC plug.

SOURCE: Compressor will not start

It is a good sign that the motor turns freely with and without air. That indicates that you have good bearings and that the intank check valve is in good condition. Next you should check the capacitors and the condition of the windings. Some motors have start and run capacitors and others only have run cap. Remove from the circuit and test with meter having cap. test setting. Most shops will test them for free. The cap should test within 95% of stated ( uf ) value. Replace as needed. Finally check that the flyball switch at rear inside of motor is functioning correctly. At rest, switch is at start winding, then a split second after start, it shifts to run winding. Check contacts are not stuck and that switch is working and lastly that the winding are the color of new penny. Good luck.

SOURCE: Changing Smeg SA280X/1 fan motor, shaft nut stuck?

Most fan blades are held on by a single nut, which is usualy a left hand thread, so to unscrew it you turn it clockwise as though you are tightening it up.and to tighten it,anticlockwise..
If the spindle turns, then you will have to hold it with a pair of grips or similar.
Plz rate my solution.
Thabks.

SOURCE: compessor trips circuit

IT SOUNDS LIKE YOUR COMPRESSOR IS NOT UNLOADING WHEN IT SHUTS DOWN. YOU SHOULD HEAR AN AIR RELIEF SOUND TYPICALLY ON THE SIDE OF THE PRESSURE SWITCH WHEN IT SHUTS DOWN. ITS A SMALL VALVE WITH A TIRE VALVE THAT THE LEVER HITS AND RELIEVES THE PRESSURE FROM THE DISCHARGE LINE AND THE TOP OF THE PISTON.

YOUR CHECK VALVE COULD BE BAD LETTING PRESSURE BACK UP BUT IT WOULD BE BLOWING AIR OUT ALL THE TIME WHEN SHUT DOWN.

IF YOU THINK THE VALVE OR SWITCH IS WORKING AND WANT TO CHECK IT, LET THE COMPRESSOR BUILD UP AND SHUT DOWN, LISTEN FOR THE AIR RELIEF,IF IT DOESNT THEN CRACK THE DISCHARGE LINE AND SEE IF THERES ANY PRESSURE, MANUALLY RELIEVE THE PRESSURE THEN USE SOME AIR AND SEE WHAT HAPPENS. REPAIR VALVE ON THE SIDE OR CHANGE PRESSURE SWITCH $30-40.00. HOPE THIS HELPS. PLEASE REPLY. JODY

The plastic cover over the fan seems to be touching the fan blades. When I remove it its very quiet but when I put it on it seems to be slightly touching the blades and makes a noise. Can this be fixed....

There are two causes
1. The blades are out of alignment Check to see if blade nut is loose and look behind the blades at the shaft to make sure the notches ate in the shaft pins, off is clockwise.

2. The cover is not mounted correctly to the fan housing. Make sure its not upside down and the two halves are together properly and rightside up

Hope this helps Mike.

HI, My Kenmore Air Conditioner Model# 76129 - turns on, makes a sound like it is going to work but the fan does not move. Thanks

When a fan malfunctions, the problem is usually loose or dirty blades. If the fan won't operate or if it's noisy, cleaning and tightening will usually fix it. Here's how to repair a room air conditioner's fan:
What You'll Need
You'll want to have these tools on hand to repair a room air conditioner's fan:
  • Vacuum
  • Soft cloth
  • Screwdriver or Allen wrench
  • Long-blade screwdriver
  • Wrench 20-weight nondetergent motor oil
  • Volt-ohmmeter or multimeter
Step 1: Open cabinet and locate fan.
Step 2: Clean away any debris with vacuum and soft cloth.
Step 3: Check fan blade on motor shaft for looseness. Blade is fastened to shaft with setscrew at hub of blade.
Tighten setscrew with screwdriver or Allen wrench. If air conditioner has round vent fan, tighten fan on motor shaft by inserting long-blade screwdriver through port in fan.
Fan is installed in its h­ousing with bolts, and vibration can loosen these fasteners. Then tighten them with wrench.
Step 4: If fan has oil ports, apply several drops of 20-weight nondetergent motor oil (not all-purpose oil) to each port at beginning of cooling season.
Step 5: If you suspect fan motor is faulty, test it with VOM set to RX1 scale. Disconnect terminal wires from terminals, and clip probes of VOM to wires.
If meter reads between about 3 and 30 ohms, motor is functioning properly. If meter reads either zero or an extremely high number, replace motor.
To remove the fan motor, remove the fan, the power wires, and several mounting bolts. Install the new motor with the reverse procedure .bobicehouse_59.jpg

My Fan is somehow loose and gets jammed. I don't see how the fan metal bracket fastens to anything and therefore is sort of floating loose and the blade keeps rubbing up against the plastic...

Fan should not be rubbing up against anything. I don't think the fan is secured properly to the motor shaft. Tighten down the metal clip that holds the fan onto the shaft. Make sure it's not back too far.

Hitachi EC 12 2hp Air Compressor. Just get a buzz sound when plugged directly into 120v wall outlet. Piston and shaft turn freely. Have installed a new pressure switch. Just turned the compressor on...

Hitachi EC12 Air Compressor Parts : MASTERTOOLREPAIR.COM

Here is a site that says:
1. Are the capacitors good? (They get the motor going).
2. If they are, replace the stator, ($245)

If you don't find a good solution there, I would try taking it to a local motor rebuilder.

How do i do it myself to install outdoor bower motor condensor motor 1/4 hospower 350 rpm and also the 5 amp capacitor. If i keep the 10 amp capacitor is that a problem?

Turn off power in all cases. If you are replacing the orignal motor for the 1st time. It might be easier if
you cut the wires near the control box and then wire
nut them together and wrap with electrical tape.

Remove the fan cover and unloosen bolt that hold the
fan to the frame or whatever it might be. After fan is out spray some WD40 that holds the fan blade to
the motor shaft. Measure the distance from the fan
blades to the motor.

Unloosen the screw that holds the fan blade to the
motor shaft.Take sand cloth and try to clean up
the shaft below the blades. Try to tap the fan blade
down towards the motor.If it moves sand the shaft above the blades. Take channel locks and grip the shaft below the blades, try turning the fan blade while
holding the shaft until it spins freely and the remove.

If the motor came with a 5mfd capacitor use it.

I plugged up my wg5005 after a year in closet and it makes noise but the fan doesn't blow any air out..It runs but fan blades aren't spinning

you said 'it runs but fan blades aren't spinning.'

Taking this "literally" - what it means is that the fan blade is 'loose' on the shaft of the motor. Look at the fan blade, the hub - in particular - and you will see where a 'set screw' should be.

If it's still there and 'loose,' all you have to do is 'tighten the screw' on the shaft of the motor (on the flat side).

If the screw is missing - you just need to find a screw that will fit the hole and replace it.

All of the above being said - it's also possible that you are hearing the compressor run and thinking the fan motor is running when in reality it's not. In the case that the fan motor is actually "not" running - then you have a completely different problem - the most likely problem being the fan motor is defective - in which case you will be out around $150 and up to replace it.

With the cost of window units today being fairly reasonable - you will probably be better off looking for a new unit.

Still, on the chance you have a simple problem, i.e. a burnt wire, or bad capacitor - it might be worth it to have a Service Tech take a look.

Hope this helps.

Sub-Zero 532 not cooling

Simple think I guess - just pull down a little a plastic fan blade on motor shift it will produce a powerful air flow. Fan blade should sit pretty close to the shift end. ;)
