A/C NOT COOLING, NOT ICED UP. MOTOR TURNS BUT THE FAN IS SITTING THERE LOOSE. IS IT SUPPOSED TO TURN OR BE CONNECTED TO SOMETHING? I PROBABLY WILL CALL A PRO BUT JUST WANT TO UNDERSTAND IT. ANY HELP?


Fan is loose on the shaft? Are you getting any airflow? That could eventually ice up your evaporator coil as well as damage the motor shaft. Is there a set screw you can tighten on the shaft?

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

How to remove fan motor


Fan

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:
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. However, if the condenser coil must be moved to get the fan out, do not try to remove the motor. Call a professional service person.

Noisy fan or motor?


HI. The most common issue here will be with a loose motor shaft. This is the part that the fan blades are mounted on. When this occurs, the looseness will cause the motor, and shaft to wobble, thus, causing this noise you here at high speeds. The wobble is less violent during the slower speeds, so it is not loud, in this case.

The second issue will be a warped fan blade. This will cause the fan to rub against the shroud, thus, creating the noise, as well.

If the shaft is loose, or bent, the entire motor will need to be replaced. Now, if the fan blade is warped, you can, simply, unscrew the blade from the shaft, and replace it(on most model)

I have a HotPoint side by side refrigerator. Model # CSX22GAS, my ice is melting and in the freezer section there is a loud noise. as if the motor is running hard.


Below is a link courtesy of www.repairclinic.com, that shows the evaporator fan blade. This may have come loose from the fan motor shaft and may be striking the fan shroud or rattling on the motor shaft
A loose fan blade cause elevated temps. If the fan blade is loose, replace it, not repair it, to avoid further problems.

Blade is loose


on the inner part of the motor [fan side] look for an external snap ring and a fiber spacer. the armature fits all the way into the rear part of the housing, the other housing goes over the motor shaft and must press against the snap ring and fiber washer.
