Sometimes get a loud screeching noise from the condenser fan motor. Also seems to be loudr than usual. Motor part no. is:S070. Can a "do it yourself" guy replace the unit?

as for noise will have to inspect under hood,could be fan or belt or pulley ,water pump .these are some things it could...My suggestion for overheating is replace thermostat. If your car has electric cooling fan then it may not be working..turn defrost on and if fan kicks on then fan motor is good..Now this does not mean that fan is working properly because fan is controlled by heat sensor switch that kicks fan on when motor reaches heat range......Things i would have checked....hope this information helps and good luck and Please rate my post...

Hello, if you cannot turn the fan by hand then the motor is shot. However, when power is applied to the motor and it starts after you give it a push then its the capacitor. Whenever you replace a motor tje capacitor must be replaced aswell because the microfarad rating of tne capacitor may have changed.

sound like the blower motor is worn out.

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.

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!

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.

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.

It's noisy If your dishwasher seems noisy, check these:

Water-inlet valve
Motor
Heater fan
Pump
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve. 

Motor If it's the motor that's noisy, either of these may be the "culprit:"

• As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).



• If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.

Heater fan If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. 

To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.
thanks and accept the solution accordingly

Check the vacume in your inducer motor. Ensure it is pulling at least -9. If you don't have the equipment, you'll have to wait till it has a problem. Or, pay a tech to come out and service your system, with particular attention to the inducer fan..

You are seriously frozen up. Defrost the unit completely. Then, be aware that 'window shopping', leaving uncovered liquids in the box and poor door sealing (too heavy a load on the door ... too much on shelves) can cause condensation. Defrost with hot air or leave unplugged and open for about 2 days. You'll see alot of water come out.
