You have a Compressor Motor in a Gateway MT3705 PC, I never thought of that as a CPU cooled, could you post a picture? Don't you find having a Compressor motor on a Laptop rather cumbersome, how is it powered? Fuel or electric?

Fridge was not cooling, but freezer worked. replaced evaporator fan motor, now fridge and freezer is not cooling at all. amana fridge afd2535deq


Did you check to see if the compressor is running? Did you mess with any of the wiring during your "repair"?

Air Compressor Burn-Out


Small, easy to transport air compressors have become very popular over the last 25 years. However they do have their drawbacks.
The motors on these small compressors generate alot of heat as they cycle, especially under higher tank pressures (PSI's) and air volume usage (CFM's). They work very hard and run more frequently. In time, this heat creates increased resistance in the rotating armature windings (which act as quickly reversing magnets against magnets in the outer case of the motor for thrust to rotate). The magnetic force weakens, the motor gets weaker and hotter and has to work harder to do the same job.
When an air compressor motor seizes in it's cycle and hums or buzzes, it is over heating to a point where a thermostactic relay will break electrical contact (to prevent Fire) and the motor will have to cool before it will run again. each time this happens you are reducing the life of the motor by several hours.

To maximize the life of your compressor, use the following guidelines:

1.Always use the shortest possible cord and plug directly into a 20 amp cicuit when possible,no extension cords! SHORT WIRE+LONG AIRHOSE- electrical current is lost through longer wire and requires a larger gauge (diameter) to carry the current.

2.Make sure the plug contacts are clean- as with automobile batteries:CORROSION=RESISTANCE=HEAT=WEAR.

3. Should your compressor begin to stall during its cycle, attempt to turn it off or quickly or reduce the pressure in the air tank to reduce the load on the motor- while the motor is moving a fan blows air through it to cool it.

4.Should the motor overheat, let it cool untill you can touch it with your hand and bleed most of the air from the tank to minimize the start-up work load.

5.Remember to try to drain the tank after each use to minimize corrosion due to moisture and minimize load the next time you start it up.

Following these guidelines will increase the life of your compressor motor several months if not years.

I have no cold air in my refrigerator or Freezer. It defrosted everything.


Condenser Coils are Dirty
If the refrigerator is not cold enough the condenser coils may be dirty. The condenser is like a radiator and must stay clean in order to dissipate the heat which was removed from the inside of the refrigerator. As the coils get dirtier the refrigerator becomes less efficient, which makes it work harder to cool down. If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the inside of the refrigerator to the proper temperature.
Evaporator Fan Motor
If the refrigerator is not cold enough, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. The refrigerator may have one or more evaporator fan motor(s) depending on the model and evaporator locations. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment. The freezer may still get cold.
Condenser Fan Motor
If the refrigerator is not cold enough there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back. Pull the refrigerator out from the wall and remove the access panel to access it.
Start Relay
If the refrigerator is not cold enough, the start relay may be defective. The start relay is a small device mounted to the side of the compressor. It provides power to the run winding along with the start winding for a split second at start-up to help get the compressor started. If the start relay is defective the compressor may run intermittently or not at all and the refrigerator will not get cold enough. The start relay should be replaced if defective.
Temperature Control Thermostat
If the refrigerator does not get cold enough the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem.
Start Capacitor
If the refrigerator isn't cold enough the compressor might be having difficulty starting. The start capacitor serves as a battery to give the compressor a little boost during start-up. If the start capacitor is burned out the compressor might not be able to start and run as often as it should. Test the start capacitor first with a capacitance meter, they don't fail often. If it's defective, replace it.
Thermistor
If the refrigerator is not cold enough the thermistor might be defective. The thermistor is a sensor which monitors the air temperature. It is connected to the control board. If the thermistor is defective the refrigerator does not cool or may cool continuously.
Temperature Control Board
If the refrigerator is not cold enough the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.
Compressor
If the refrigerator is not cold enough, the compressor might be defective. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. There are several other components which are more likely to be defective if the compressor doesn't work. If the compressor itself is defective a licensed professional will need to replace it.
Main Control Board
If the refrigerator is not cold enough the main control board might be defective. This is not common. Check the defrost system, cooling fans, and cooling controls first.

I have a fedders (piece of junk)3 1/2 ton 4 year old unit. It runs fine during the evening after it cools off, but during the day it constantly cuts off and on unless I am spraying it with water. As soon...


sounds like your compressor is overheating is the compressor sweating down the sides? If it is you may have an airflow problem clean filters, clean blower fan motor and the evaporator coil. if this does not work you will need to have someone put a set of manifold gauges on it to see if the proper pressures are where they need to be. Also you can check the amps on the compressor to see if it is sezing or if it is locking out. The compressor is getting to hot is the reason when you squirt water on it runs because you are cooling it down. have you cleaned the condensor coil? Your head and suction pressures will give you a good idea.

Refrigerator is not cooling


Dirty condenser, condenser fan or evaporator fan motor are not running, Ice build up on evaporator and restricted the air flow. If compressor, condenser fan and evaporator fan motor are running but not cooling, then either compressor or sealed system problem.

Motor not running Refrigerator not cooling


There are three possibilities why the compressor motor is not running. #1. The thermostat switch is not closing to turn the motor on. #2. The compressor motor is bad. #3 The defrost timer is engaged, preventing the compressor motor from starting.

Solution for #1: Locate the thermostat switch behind the console in the refrigerator. It is attached to the freezer temperature adjusting knob. If you jump the switch out, the compressor motor should start. If it does, replace this switch.

Solution for #2: get another refrigerator. It is not worth repairing.

Solution for #3: Turn the freezer temperature switch to the coldest setting. Locate the defrost timer in the console on the ceiling of the refrigerator compartment. Look for position labels like "cool control" and "compressor". Jump between these two wires. The compressor should start. If it does, replace this module.

Not cooling good


There is a fan down by the compressor that aids in cooling compressor and getting rid of the water that comes out of the freezer during defrost cycle. I am sure that you took the paper cover off the back of the unit on the lower back side so your unit might not have a fan. Now lets look at the fan inside the freezer is it running can you hear it when you open the door? Does the compressor make a clicking sound as it is hot to touch and trying to come on? get back with me ok ken

I have GSS25SGP SS with no condenser fan operation. Components very hot, but unit is still cooling. Is this fan shut down a part of the defrost cycle or a fan motor failure? aerolog2


The fan has to run when the compressor is running. Usually does not run during defrost cycle. Could be bad fan motor, or the fan has lost power.

My first thought is a compressor not running from your description of the clicking.

Compressor problems can be:

Could be a Relay, stiff compressor/motor assembly, low voltage, run, or start capacitor if so equipped.

You will need a voltage (amp meter would help) meter to check the voltage (amp draw) at start up on the compressor to determine if you are making headway on finding the cause.

You will have to verify the voltage for sure and during start up 1st unplug the refrigerator let it sit for 10 to 15 minutes. 1st During this time check the voltage at the wall plug. 2nd AT the compressor relay (2 wires to the compressor) when it first try's to start meaning while someone plugs it in. The reading can be up to 10% lower during this time. continue to watch the volts as it runs until it clicks again and cuts off. The voltage then should return to where it was at the plug-in. If not We now have a problem outside the compressor area. If so we are on the right path.

A replacement relay and overload (with the run and or start capacitor if equipped) replaced as a whole at the same time will either confirm its one of these components. With them replaced and correct voltage range during start of the compressor it will either work or your compressor is out.
