This is a good question. On a standard refrigerator the fan gets its power from the cold control thermostat. On an electronically controlled refrigerator the power usually comes from the control board.

After power outage the fridge was displaying codes SY and EF I have Frigidaire model number FGHS2365KF1. Any thoughts?????


Hi.

SY: Defective evaporator system. Check evaporator fan, thermostat and heater.

EF: Evaporator Fan defective. Test and eventually replace the evaporator fan.

The problem is likely the evaporator fan. Before replacing the fan test the other parts comprised in the evaporator system.

Here a tip explaining how to test such parts with a similar fridge model: Fridge not cooling. Procedure is more or less the same with your model.

Here parts and diagrams for your model.

Generally you can find parts and diagrams for most appliances using the links listed on this page:
Where do I find parts and diagrams for my appliance?

We have a True TS-49F freezer that the interior fan have stopped working. Holding the door switch does not activate them. Unit is out of warranty.


Most all commercial freezers like yours have, what is called, a fan delay. It is located in the evaporator case and is usually attached on or very close to the actual cooling coil. It may also be a combination switch known as a defrost terminator/ fan delay. It's purpose is to keep from circulating warm air. If the cooling coil does not reach a preset temp, the fans do not come one. Another thing is that the fan motor may just be bad. If you have more than one fan, then chances are that it's going to be the fan delay. I would start there to see that either the fan delay switch is bad or there is a reason that the coil is not getting cold enough to activate the switch.

Compresor wont start and when it does it cycles on and off


Does the condenser fan come on? I am assuming the evaporator fan (inside) is blowing? The way these units are wired is that the power goes the the inside unit and the controller inside sends power to the compressor and condenser fan. But if the controller detects that the condenser fan is not turning (via no ground return) it will not send power to the compressor. This to protect the compressor. Did you notice it trip a breaker? When it is on, do you have 240 on the unit outside but not 120 to ground from each leg?

The evaporator fan is not blowing


The evaporator fan should be running. A light frost is what you want to see. Just no heavy frost, that would indicate a defrost problem. Check the fan for power if it has power and it is not running replace it.

Unusual noise and ice all over the freezer


This sounds like the fan is hitting the ice. If it's iced up, remove the food from the freezer and place in refrigerator.

Take the bottom panel out of the inside of the freezer section and then remove the back panel from inside the freezer section. You will then be able to see the evaporator fan. You will need to check to see if the evaporator fan will turn with the power of the refrigerator turned on.

You also want to look to see if the evaporator fan is turning and hitting ice which means the evaporator is froze up. You will need to check and see if the evaporator fan is bad or the defrost timer is bad.

Compressor in fridge not working. Freezer is working fine. Is there a reset button? What steps can I take to see if this is a simple issue?


There is one compressor that serves both the freezer and refridgerator compartments. You need to confirm if the evaporator fan in the freezer compartment is working. When you open the door to the freezer, you should see and hear the evaporator fan in the freezer compartment running. Particularly if there is a demand on the unit through the thermostat setting. If the evaporator fan is not operating, you can check the evaporator fan motor with a volt meter to see if it's getting power. If its getting voltage, but not operating, you need to replace the evaporator fan motor in the freezer compartment. There are 3 wires that attach to the evaporator fan motor. One hot wire, one neutral wire and one ground wire. The ground wire is usually marked green, the voltage wire is usually marked black and the common wire is usually marked white. You should get a reading on your volt meter of a voltage from the hot post to the neutral or from the hot to the ground. If it is getting power but will not operate, then it is definitely a bad fan motor that would need to be replaced.

Not cooling no p0wer to evaporating fan


Part number R0161089 defrost thermostat $35 ,but if the freezer coil is defrosted there would be no power to the motor because this switch has to be chilled to about 0°F to send the power to the fan motor.
