Question about Refrigerators

1 Answer

Fridge not cooling, freezer is ok.

I have an LG fridge freezer. model gr359sq. The freezer is fine but the fridge is not cooling. I have checked the fan which is working fine, i have defrosted completely but has made no difference. I am stuck as to what the problem may be. I've also cleaned the coils etc. When i took the fridge temperature control out of the back of the fridge compartment, there didnt appear to be any electrical wires connected to this. (how does it control the fan?) Is there any way i can test the pcb or control sensors to locate the fault? This fridge is just 2 years old.

    Thanks for your reply.

    It does look like you described but I just cant figure out the functionallity of this. How does it actually control the temperature?
    It is a dial with a thin pipe that dissapears into an insulated compartment which detaches from the fridge.

    From what i gather, there is no way it can possibly communicate with the fan or pcb to tell it the temperature should be increased or decreased as there are no wires connecting this unit to the rest of the fridge.

    How do I bypass the theremostat then? I have read that i need to reconnect wires but there are no wires to reconnect.

    Thanks for all your help.

    I have opened the control again and there are no wires connected.

    I have done a self test with the button on the PCB and this lights up the vaction and quick freeze buttons. It also turns all 5 temperature lights on and makes two beeps.

    I have downloaded this manual but it's not making sense to me.

Its usually a bulb of heat sensitive Gas then a long thin pipe that eventually connects to thermostate switch, bypass this switch to seee if that could be the faulty part. Good Luck , the Yeti

    Take the unit to bits with the dial, there you will see the wires, its a simple switch that just turns the compressor on or off or the fan on or off, dont get a shock! the Yeti

    behind the dial are the wires you need to bypass, the Yeti

Whirpool wgi fridge freezer, fridge not cooling?


Most frideges get all their cooling from the freezer. There will be a fan and duct in the back of the freezer that pushes cold air down into the fridge. If the duct is blocked with ice or the fan motor has quit. Your freezer will work fine but the fridge will barely cool at all. Check that the fan runs when the compressor is running, ( turn both temp knobs to the highest cooling and leave door open until comp. comes on). If the fan runs your duct is plugged. If not you need a new " Freezer Fan Motor". Most are simple to replace and cost around $100.00.

LG Refrigerator has no cold air for fridge but freezer works fine


Sounds like the freezer fan(FF)is wearing out, This problem is very hard to diagnose because the fan spins but not fast enough to circulate the chilled air thru the freezer and refrigerator. This repair costs parts and labor around $300.00

Our LG GR359SQ Fridge Freezer, the fridge has stopped cooling. Everything else seems to still work, freezer, lights etc. But the fridge is warm. Any thoughts?


Make sure the the evaporator fan is running and circulation is getting to the fridge side. Remove anything that could be blocking the vent that brings in the air from the freezer to the fridge. Make sure that no frost is building up in the back of the freezer. If there is frost, then the timer can be going bad.
