Question about Haier Refrigerators

1 Answer

I am using a Haier HNSB02 for a school project and will be modifying it. I need a diagram/schematic layout of the cooling and electrical system otherwise I will be tearing into it blindly. Does anyone know where I can get these documents?

    I want the mechanical schematic ( i.e. piping, and electrical system). I don't really have a problem physically with the fridge, but I want to be safe when altering the fridge.

    what is it you want to do exactly?


1 Answer

You can't interfere with the pipework apart from a little gentle bending or you will lose the refrigerent and it won't work.
if it has a standard type of stat then live is fed to the stat and hence down to the thermal overload of the fridge electrics.
neutral goes to the compressor relay and is not switched.
the fridge light is fed from live from the stat and neutral from a seperate wire from the incoming supply
not very clear i know but hope it helps

Typically, that would be caused by failure of a cheap chinese control board. In fact, failure-prone chinese control boards are at the heart of virtually all premature failures of modern appliances. They usually only last just long enough to span the warranty period.

There should be an electrical schematic diagram attached to the back of the unit. You may be able to use that to identify the faulty part. Don't be surprised if the replacement board costs alot more than it's size and simplicity might indicate.

Haier Model HNSB02, Serial # 1005006483--Not keeping within 36-46 degree temp inside. Adjusted dial on rear of model-is higher number colder temp?

I'm Leo
Yes higher numbers are colder
First I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if freezer control is turned WARMER, which makes the Ref. colder
Also this might be a common Defrost problem, Ice
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

How do you get to the 1/8" supply line from bottom of freezer door to the water dispenser Amana SXD22S2W?

you will have to check the connections first.also you if the connections are there previously and you have to convert them to 1/8" then you can just connect the wire.but if there is no connection and you have to modify the unit then electrical connections has to be checked.but actually there is a electrical connections already in most of the units between bottom of the freezer and water line. you can click this link directly for the wiring diagrams/schematics --------- thanks.keep updated.

I have a mini fridge at school, a small Haier. My fridge is getting power and the motor gets very hot but the fridge is not cooling, not even a little... any ideas???

Hi ejb9,

I'm Harvey the Master Plumber.

Your question is: You have a mini fridge at school, a small Haier. Your fridge is getting power and the motor gets very hot but the fridge is not cooling, not even a little... any ideas???

May be low on freon or cloged expantion valve. You're going to need a certified tech to check and repair. Maybe it's time to look at the cost of repair verses replacement.

Feel free contact me again!
