SOURCE: hotpoint hss25gfph ww evaporater fan is not

You need to replace the main control board . One of the resistors , are burnt , keeping the DC voltage , from reaching the fan . Check to see if the fan will run off a little 9 volt battery . If so , replace the board . Pt # WR55X10656 . The board cannot be repaired ( with this problem ) and has to be replaced .

SOURCE: the evaporater coillis frezed up

Hello,
That is going to be a problem with one of the components in the automatic defrost system. It is supposed to automatically defrost. Turning it off overnight to melt it will defiently help. If you are mechinacally inclined here is what to check to see why it isn't defrosting;




DEFROST HEATER ...remove back wall of freezer and you will see a black heater at the bottom of the coil thats frosted up,it looks similar to the bake element in your oven,or in some cases it is going to be a spiraled wires inside of a glass tube. To check it,use a multimeter set to the lowest ohms of resistiance setting and follow and find the wires at the top of that frosted coil,unplug/disconnect those wires and check for continuty with around 5-20 ohms of resistiance. If it has that amount of ohms the heater is good. If your meter display does not change or displays OL the defrost heater is broke and needs to be replaced

DEFROST TERMINATION THERMOSTAT... it's round and has 2 wires and clips to the top of that frosted up coil. IT MUST BE CHECKED WHEN COLD SO BEST TO DO WHEN FROST IS STILL BUILT UP. To check it disconnect the wires on it and check for ZERO ohms of resistiance. As with the heater if the meter display OL or doesnt change,it is the problem

DEFROST CONTROL...it is hard to check for a semi unskilled person and if the heater or defrost t-stat check good its going to be the problem. It will NOT be in the freezer it could be on back wall or inside the control panel in the refrigerator section.

I have a frost free hotpoint and theres ice on the freezer door and the food inside it what could this be and how,do i fix it


Hallo

Frost free means there is an evaporater coil behind the backplate of the inside of your fridge.

How it works is a fan is for example installed in the lower back of your fridge and the evaporater above the fan covered by a plastic cover/steel plate and now the fan is pulling the warm air from the top over the evaporater ( the evaporater is then pulling the warm air into the evaporater without increasing the temperature of the evaporater) and dehumidify at the same time and blowing the cold air out a the bottom of the backplate while the warm air moving to the top where it could repeatedly repeat this action.

Tell me what is the condition of your freezers door seal? It can only be caused by humidity getting in so it mean the door is not sealing 100%.

Refrigerator not cooling top shelf


it sounds as though you have a fridge that is low on freon. If the ice is appearing mostly to the left, then thats surely your problem. if it goes all the way across, you may have a bad evaporater fan motor, fan motor switch, bad cold control, or just a door that isn't closing or sealing properly. If its the ice mostly to the left side, it probably means your evaporater is leaking the freon. I am assuming you have a model that has a cold control on the back wall, not the electronic display by your description. If your unit is less than 12 years old by the installation date, the part will still be under warranty (sub zero has an unmatched 12 year sealed system parts warranty) but the labor and freon will not be. The repalcement of that evaporater in my area usually runs about $450 with labor, freon and trip all together. It is a repair you cannot do unless you have an acetlyn torch and some silver-soldering/ brazing ability. If your model is in fact the newer style with the electronic temp display, call sub zero up (the # is on the model/serial tag in the door jamb) and tell them wahts going on. If it is in fact an evaporater leaking on this style, they will most likely pay the bill for you even if its well out of the 5 year full warranty. If you want to know for sure, remove all the shelves, then remove the cover over the lights. Then if its electronic remove the 3 screws holding the top of the back panel and tilt the panel out to you and pull it up and out: if its a dial type, remove the 2 screws holding the fan cover and then tilt the back wall out to you and lift it up and outwards, but not too far as it wil pull the wires of that control knob (cold Control) Look at the coils back there and see if the coils are frosty. If they are only frosty on the upper left of the coil, its low on freon and needs an evaporater. if its frosty all the way across, top to bottom, you need a cold control, or possibly a fan or fan switch. Hopefuly you can wade through all this. Just post back if you have any questions. Good Luck!

Fan has power to it intermittantly,but sometimes not at all.With the door open, the light blinks off and on, but sometimes stays on.Of course when the fan doesn't run, the cold air cannot circulate.


It operates as follow:
L(usually brown wire) is connected to the C(common port) of the DOOR SWITCH.
Now the DOOR SWITCH usually had 2(A) or 3(B) ports:

A: Port 1 = Common.(C)
Port 2 = Normally close(closed stream)(N/C).
B: Port 3 = Normally open (open stream)(N/O).

(L) connected to (C)
When door closed;
(C) - (N/O) supplying to Thermostat, from Thermostat to evaporater fan and Compressor (to condenser fan if applicable).

When door open;
(C) - (N/C) supplying lightbulb.
And cutting (N/O) supply.

Now of evaporater fan is not running;
1st, evaporater starts to ice up and the the ******* copper pipe starts icing up all the way to the compressor causing Liquid Refrigerant sucked into compressor that could cause serious damage to compressor.

Firdge turns on but never gets cold. Runs constantly. Refridgerant maybe?


Is the condenser fan turning? Is the evaporater fan turning? Check the evaporater at the freezer compartment it should have fine frost all the way if no frost or partly frosted may be low on freon.Be sure there is no air leaks around door or something. Hope this helps.

Freezer working fridge not working


Check to see if the evaporater fan in the freezer is running. Check if frost on back wall of freezer from bottom to about 3/4 way up. If frost then you have a defrost problem. If fan is not running check for opstruction (ice) blocking fan or motor. If frosted will be either defrost timer, thermostat, or heater.

Can i use a non computer evaporater fan in this ge fridge


As long as the size of the fan, the voltage, and the rpm are the same it doesnt matter. If you still dont feel comfortable about it, computer fans are very inexpensive.
If the fridge has the proper amount of freon and the compressor is working and there are no leaking gaskets then the thermostat would be the logical conclusion. Especially if and I am assuming you have it turned up as far as it will go.

Refrigerator i not cooling. Do not feel any air moving on either side.


You access the fan in the freezer section towards the bottom half. there is a thin metal panel covering the fan and evaporater coils. Take out the shelves and then remove the screws to the bottom section starting approx halfway down the back of the freezer wall there you will find the evaporater fan.

Compressor and fan work on cendenser, evaporater works, but the fan on the evaporater in the freezer rear cuts off after the initial run cycle. The coils then freeze. What are your suggestions replace...


Probably a bad defrost thermostat. The fan motor power runs through the defrost thermostat then to the fan motor.If the defrost thermostat is opening too soon, you get no fan and no defrost.
Yes you can replace this part yourself.

Kenmore refrigerator condenser fan not running. It does not appear to have current to it. Is there a thermal switch that turns the fan on or is it supposed to come on with the compresser?


I don't get 120 volts to my evaporater fan motor. What part do i need to check or replace to get the evaporater motor to work? I have replaced the motor, but it still doent come on.
