Trace the power to the control circuit and check if the power is switching on to the compressor/fan. If not the control unit is faulty and unless this is corrected the position of the fridge cannot be determined.
So use a continuity tester to proceed and move on to trace from the power plug to the main controller.

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.

Freezer cool but not freezing; refer cool but not cold


When the compressor is running all the time and the freezer is not cold enough, it could be the hot side can't lose the heat, see if something is blocking the radiator on the back, but most likely you lost the cooling fluid through a leak in the cooling system. When the temperature is rising slowly through the days (or hours) while the agregate is running, that will be the problem. You won't be able to fill it up yourself. The system is filled and sealed.

How do i get my condenser fan to stop running. it is cooling fine but won't shut off unless i shut it off.


Are you sure its the condenser fan? The fan is attached to the compressor power and wont run unless the compressor is running. On the other hand the fans inside the cooler will run 24/7 and are designed for continuous duty. If someone has worked on the compressor wiring you may have to re establish the wiring following the wiring diagram. I have seen condenser fans wired in hot areas to run continuously to attempt to cool down a hot compressor or compensate for a worn out or damaged condenser that doesn't get rid of the heat from the system. If that is the case a new condensing unit is probably in your future. Hope this helps good luck.

Refer warming / no compressor / no fan


If the fan doesn't work , the compressor overheats and shut off by the overload protection.I would replace the fan which will cost no more than $30.

My Duo Threm RV AC wont get cold


this could be the controls for the compressor circuit (thermostat) or the starting components for the compressor, (capacitor) or the compressor itself. Start at the compressor with a call for cooling, verify voltage, if there is voltage a tht compressor terminals, most likely the compressor will need to be replaced...trace back to the source of power if no voltage is at the terminals, and you should locate the culprit...hope this helps..

My Fan in the back of freezer is not working?


You need to have a voltage tester on the fan terminals. if power is shown and motor doesnt turn, then fan must be replaced. If no power is shown, make sure you press the button on top of the door frame. basically, if door isnt closed, fan wont work.(This is referring to the freezer fan inside the cooling cabinet). If its the fan next to the compressor you are referring to, it must run at all times while the compressor is on. If not, replace it.

Hot air comes out of defrost vent at top dash and cold air out of


Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:
730c4b9.jpg

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted

Oasis drinkingfountain - Why would fan run continually? Cools wel


The fan and compressor run at the same time.
Both get power from the on/off cold control termostat.
1.Defective thermostat.
2.Compressor not cooling.

If the water is chilling go to #1.

Refrigerator stopped working, freezer works fine


Sounds like the evap fan is not running. The fan takes cold air from the freezer to cool the refer compartment. If the freezer is cold the compressor is running. Generally the freezer will stay cold since the cooling coils are there but it must have the fan working to get the air up to the refer area. Pull everything out the freezer and take the back panel off to view the coils and fan, etc. It's a simple easy job to change the fan. If you find the coils are a total block of ice then it's another problem... the defrost cycle isn't working. Sooo... see if the fan is running in the freezer compartment first. See http://www.partselect.com/Schematics/Maytag/AA43-57.gif for fan location, item 18 is the fan motor. Let us know what you find out.
