WHIRLPOOL CB18M FRIDGE FREEZER

What is the model number of your refrigerator? In most cases replacing a mechanical thermostat that begins doing this is the answer to solving this problem. Problem is I don't know what the type of thermostat yours has because you did not post the model number. Thanks, Sea Breeze

On your model your cntrl board has a relay that can stick causing the compressor to always run even when the unit is turned off or in defrost. turn the fridge off, move the temp of the freezer to it's warmest setting and it should display a line in the freezer and fridge temp display. listen to hear if the compressor is running in back of the unit. if it is you need part number: 12868513

If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Air from the freezer is blown into the fridge by a fan, some new type frigs have electronic controls that open and close a vent to frig. the older ones have two vents in the frig from the freezer and when covered with frost or ice the air will not reach the frig. check for ice or just defrost the freezer if there is ice or frost, also check for food or plastic over vents in freezer. Also check that the freezer fan is running as these sometimes become blocked or defective motor.

change thermostat sensors in fridge and freezer easy

Howard,

Your defrost system has gone out. Check your heaters first then the
t-stat and timer. We have parts so if I can send them to you, please give us a call. Hope this helps! Ella

check to see if the evaporator fan is working in the back of the freezer panel

you need to probly replace the thermostat for the freezer.

Hello cokoliso,
Welcome to Fixya

You said, your Trio won't make ice. Freezer stays at about 25 degrees regardless of control setting. Fridge maintains 40 degrees at mid setting. Shouldn't the freezer be close to zero? Is there a way to check the temperature sensor in the freezer?

To check the temperature you can buy a refrigerator thermometer at the hardware store.
Ask if it can be used in the freezer too!

The fridge sounds slightly to cold and the freezer not enough.
Fist look in your freezer and check if the articles there are full to the max and covering the air vents usually found in the rear of the freezer.If so clear an opening for the freezer to breath.
Refrigerators and freezers usually share the cold air and I've seen this be the problem on many occasions.
If freezer was not I blocking the vents or even full to the max.

Then pull the plug out or if you can not reach the plug, trip the breaker off for 5 minutes and see if this resets the system.BUT do not plug the fridge back in before at least 3 minutes.

Let me know how it goes and send me any questions.
Thank You, Huuum
Please remember to leave a rating .

Is the 8 degrees centigrade? If yes check the freezer fan or for frost at back of freezer...and give me a holler.
