Tip & How-To about Refrigerators

Side by side refrigerator whistling sound coming from freezer fan area

We had a lot of inquiries with what we call whistling appear to be from different problems which here below:

First case, whistling sound is what we call "Ghosting". To get rid of this sound one needs to put more gas into the system, but more gas will create the suction pipe to frost up and reducing the gas level will create less cooling. The best solution were to full regenerating Freon gas mean remove it filter it out and charge it back. However this will cost more $100 and basically you can leave it and live with it. No harm is created only the sound appears while running.

Second case were with a loud whistling, like a dying bird stuck in your freezer, you likely have a faulty freezer fan motor and you need to be replaced


Third case were with a lower pitched, sort of gentle whistling sound then you have an issue with the door damper, which allows the air flow from the freezer into the refrigerator. And assuming you don't have any cooling problems, it may simply be a normal occurrence, as some makes and models open and close this damper door automatically, and when it is closed, can sometimes cause a low whistling noise

Fourth case was making a moaning, whistling noise coming from just above the ice maker. It happened when the fan speed changed. We found out that the motherboard was probably defective.
Rather than go thru GE, you can found a new one online for 66 bucks. You can replaced it in about ten minutes and it's all fixed.

Fifth the evaporator fan motor should not change speeds in less than 1 minute of time. The fan motor has two speeds. Usually this is a indication of a failing main board. If you have a meter you can do a voltage check at the J-2 connector on the board. Check for 13VDC between pins J2-3 and J2-8 and 8 to 13VDC between J2-3 and J2-4. If this voltage stays steady, your problem lies in the evaporator fan motor. If this voltage drops out or fluctuates, it's more than likely the board need to be replaced

land cruiser turbo light on


There is not much I can advise you on because you have not provided enough information. Are we talking about a gas engine or a diesel engine? What YEAR is your Land Cruiser? I cannot look up any service information or things like Technical Service Bulletins (TSBs) without knowing exactly what we are talking about.

"Toyota Land Cruiser" covers a lot of different years, a lot of different engines, and a whole bunch of differences in engine control systems. All I know at this point is that it is equipped with a turbocharger.

My vehicle makes a load whistling sound whenever it is traveling above 60 Km per hour


That sounds like an air movement problem and not a mechanical problem. Check for something plastic or rubber hanging loose below the front end of the car. If a flap has the connecting push pin missing leaving the connecting hole open it can make this sound. Also check the firewall for missing rubber plugs. If you live in an area where there are lots of deer you might want to leave it alone as the high pitched whine keeps them away from the roadway.:)

I get a whistling sound at start up and the service engine soon light stays on...What could cause this


a broken or loose vacuum hose is more than likely the case. Also check the air inlet connections. That can be loose as well
