Hello, usually there is a set screw or a clamp that hold the fan blade to the motor. If it is a set screw just tighten it up, if it is a clamp it must be slid over the hub.

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

I have a neff fan built in oven everything is working except the fan is it a matter of just replacing a new fan?


Make sure there is a supply to the fan before attempting to replace it, if there is and the fan does not work, then replace it.
If the fan element is getting hot, but the fan is not working, then you need to replace the fan motor assy.
It is a fairly straightforward repair, but remember that the fan blade assy is secured by a left hand thread, so unscrew the nut clockwise as though you were tightening it, holding the fan blades as you do it.

Blower motor doesn't work, how do I find out if its the fuse, relay or if the motor itself is shot? I know where the fuse box is but some of it is abbreviated and I don't know what some of it stands for....


The blower motor can be tested by removing the lead to it and seeing if it has 12 Volts by observing if the 'test light' lights up when the dash controls indicate that the blower motor should be operational.

One can test the fuses by using a 'fuse tester' available from Walmart or an auto parts store which will light up when an energized circuit has a blown fuse.

The blower motor is located on the firewall on the passenger side, in general on GM cars from the 1990s.

You may have to remove some items to get to it, though.
Blower Motor REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. If necessary, tag and disconnect the number 2, 4 and 6 spark plug wires from the ignition coil and move the coil out of the way.
  3. For 1993-99 vehicles, remove the nuts and cross brace bar.
  4. Detach the electrical connections from the blower motor.
  5. Disconnect the cooling tube from the blower motor.
  6. Unfasten the screws securing the blower motor to the blower module assembly.
  7. Remove the blower motor and fan assembly from the module.
  8. If necessary, unfasten the nut attaching the fan to the blower motor shaft, then pull the fan from the blower motor. Fig. 1: The blower motor and fan assembly is mounted in the heater and A/C module, and is accessible from the engine compartment 89636g22.gif
    Fig. 2: You can disassemble the fan from the motor by removing the retaining nut 89636g23.gif
    To install:
  9. If the fan was removed from the motor, position the fan on the shaft, then install the retaining nut. Tighten the nut to 12 inch lbs. (1.4 Nm).
  10. Position the blower motor and fan assembly to the module, then install the retaining screws. Tighten to 5 inch lbs. (0.6 Nm).
  11. Connect the cooling tube to the blower motor.
  12. Attach the electrical connector to the blower motor.
  13. On 1993-98 vehicles, install the cross brace bar and retaining nuts. Tighten the nuts to 18 ft. lbs. (25 Nm).
  14. If removed, install the coil and connect the spark plug wires, as tagged during removal.
  15. Connect the negative battery cable.

I have a model 5BS520C. The light works but when I pull the chain for the fan, I hear the sound of three speeds but the blades do not turn. ed.pfohl@gmail.com


Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

Minka F602 - One of the two fans vibrates and makes noise.


I don't understand what you mean by "uneven spacing between the blade housing and the motor housing." If physical spacing is the cause, then you should be able to fix it by tweaking the blade housing into a new position or re-mounting it by drilling new mounting holes of your own and using sheet metal screws to secure it.

The fan inside might just be unbalanced though. Try tightening the large brown peg on the back of the fan head, and try tightening any other small screws that you see holding the fan head or cage in place. Heck, maybe even loosen everything, reposition it a little, then re-tighten.

Balancing the individual fan blades would be tricky because they spin at such a high RPM, but it could be done by using a strong epoxy to stick the correct amount of weight on the blades that need it. Figuring how much weight to put on which blades would be the hard part.

Fan blower motor


The Canyon has an inherint problem with the Fan Power cable being loose. When I say loose...I'm saying that you need to adjust the wires and then take a zip strip to tighten it up.

Passenger side under the dask are 2 cable hook ups. the one on the farthest right (Only 2 wires going to the plug) is the fan power cable. Jiggle it while the fan is on position number3 so you can hear when it comes on!!!

FAN MOTOR FOR 1995 MERCURY COUGAR XR-7


If the fan is electric it may just not be running when the engine is cool enough. Be sure to check it when your engine is hot, after you've been driving for a while. The battery may have a bad connection somewhere. Can the battery move when your accelerating? If so you should repair/replace the mounting hardware for the battery. Check the wires and connections to/from the battery and tighten/clean anything that is loose or dirty.
