Please help mdl # BX21VL s/n 9910131900 freezer works fine refidgerator does not. no cold air blowing out of vent

If you have an error code showing or flashing then try is Powering off the FF at the AC mains supply and leaving it standing for 30 minutes. Make sure that you do not open any of the doors or touch any of the controls during this time. Then reconnect the power and wait for 30 to 60 minutes to see if the fault remains or is cured.

Try completely defrosting the FF as despite common belief these units are not totally frost free.

If the Freezer and the Fridge are not cooling enough then check that the condenser is not iced up and that the fan is running correctly. These are located behind a panel in the lower half of the freezer at the rear and can be accessed from inside the freezer compartment.

In modern uprights if the freezer part is working OK and the fridge is not working correctly it means that the air vent from the freezing unit to the fridge compartment has stuck in the closed or partially closed position which causes the fridge to not be any where near as cool as it should be. If it is too cold then the vent is stuck in the open position and the fridge temperature will continue to fall and become the same as the freezer, thereby freezing the contents of the fridge compartment. It can also get stuck in another position so that if the temperature is adjusted on the front panel then nothing happens to the temperature in the fridge compartment. The vent is controlled by a small sync motor and either the motor has become faulty, the control module is faulty or the vent is iced up. It can be come iced up by putting too many hot items in the fridge so the steam condenses and freezes the vent in position and then the motor cannot open or close it causing it and / or the control module to become faulty. Other times it is just old age that causes the motor and / or the control module to fail. If the sync motor and vent are working Ok then there may be a fault with the fridge temperature sensor or main on board controller that will mean that the sensor or the controller will need replacing.

In stand alone fridges the answer could also be that the cooling panel at the rear is dirty and needs thoroughly dusting / cleaning / unblocking and checking that there is enough space around it to cool properly and that it is not near any heat sources such as an oven, air vent, microwave exhaust, etc.. It could also be caused by a problem that has resulted in a loss of the refrigerant gas and will need regassing by a service engineer. Also check that the thermostat is working correctly, turn it up and the fridge compressor motor should kick in, turn it down and the motor should turn off. Also make sure that the fridge is not iced up, or overloaded, so cool air cannot circulate inside it. Best call a service engineer asap.

Sounds like the fan which shifts air from your freezer to your fridge has stopped working, you will need a technician to replace this fan motor.
