Question about Refrigerators

1 Answer

Sharp SJ-42-WH self-defrosting fridge. Freezer works fine, but fridge doesn't cool down - no airflow to fridge. 1. Damper working perfectly and not jambed in closed position. 2. Fan working perfectly 3. Thermostat in freezer fine 4. Evaporator fine - no ice build up, so auto-defrost seems to be working. Turned fridge off and left doors open overnight. Did find water on the floor. Switched it back worked fine for 2 weeks, but problem is back - no airflow to fridge - checked damper - it is in the open position. I'm stumped. Am wondering if a re-gas might sort out the problem? 4.

    Problem: Sharp SJ-42E-WH self-defrosting fridge. Freezer

    In addition to the above:

    • I switched the refrigerator off again last night and turned it on again this morning

    • I removed the coverplate so that I can observe the damper to make sure that it isn't in the closed position

    • I measured the temperature in the freezer to be minus 7 degrees

    • Depite that and the fact that the fan is working, very little cold air is being forced down the duct by the fan - holding my hand at the duct inside the fridge only a very small amount of cool air seems to be coming through (door switch manually held to engage the evaporator fan)

    • I have used mirrors to check that the air duct isn't blocked and have even blown air through it with a hand-held blower

    I'm at a total loss, Airflow definitely seems to be the problem though and it is not the damper. I'm wondering if any other ducts exist which might have become blocked due to accidental spillage in the freezer?

    Please guys - any suggestions at all will be much appreciated

I recently had exactly the same problme with this model refrigerator. I found the problem to be the defrost timer. It is located behind the panel on the back of the refrigerator where the mains cord is located, you will need to replace it with the exact same model. I am in Australia and managed to find the exact part on ebay cheaply from a local appliance parts supplier, any appliance parts supplier that deals in Sharp refrigerators should be able to help you.

You will have to defrost the refrigerator overnight again before doing this repair.

Of course there are a couple of other components that could cause this problem, you can acutally check to see if the defrost time is moving by taking note of it's current position and then checking it every thirty minutes or so. If it does not move then it could be faulty, make sure also that power is getting to the timer as well.

If your freezer is full of food move everything about an inch away from the back wall. This should let the air flow better the fridge gets its cold air from the freezer. So you have to make sure your not blocking the vents.

Why is Fridge not cooling well?

The part number you need is going to be WR09X10050. This is for the damper assembly, but while you are at it change out part number WR55X10150. this is the part that controls the damper and more than likely if one fails the other will be soon to follow

Its defrost problem.--------- When you open the freezer door, then ice starts getting defrosted, because outside temperature is warm and due to that inside ice gets bit melted.--------- -------------- The working procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located. ----------- The damper is operated by a motor.Its a complete damper assembly with motor included in it.--The damper has door.Which closes and open with the help of motor.In your case the damper door is blocked by ice, because your refrigerator is not defrosting.But when you open the freezer door, the inside ice gets bit warm and it starts melting and this lets the fridge section get cool.------------------- In this case you will have to manually defrost the ice and inspect, if the problem solves.For manual defrost procedure, click the link below:-------- Click this below for more detail:--- ----------- This will help.Thanks.Helpmech.

Sharp SJ-F80SP-BK 4 Door refrigerator doesn't cool, freezer (bottom) working fine

When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 4 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from or from online sears part site. ------------- Thank you.

Hotpoint CTX16CYSJLAD freezer works fine but fridge isn't cooling

normally when the freezer works but the refrig doesnt, it is a sign that you either have a defrost problem or your evaporator fan isnt working or the airway between the ref and freezer is blocked. first I would check to see if the fan is working in the freezer section. If it is working then I would check to see where the air comes into the ref from the freezer and make sure you have airflow into the refig section. Some models have a thermostatically controlled damper, i dont think that is what you have though. If you dont have airflow you need to check the defrost system. your would need to remove the evaporator cover and check for icing or frost over the coils. there is several parts to the defrost system. Timer or control board, defrost limit tstat and the heater. To test these components you would need a volt-ohm meter.
