The refrigerator just shuts down, stops working without any visible problem

When a Coolix 4000 chiller faces unexpected shutdowns, it could be due to various technical glitches.



Electrical Issues: Ensure that all electrical connections are secure and that there's no visible damage to the wiring or connectors. Check the circuit breaker and reset it if it has tripped. Inspect the fuse and replace it if necessary.



Thermostat Malfunctions:

Ensure that the thermostat is set to the correct temperature and is functioning properly. Reset the thermostat and check if the chiller resumes normal operation.



Refrigerant Leaks:

Inspect the refrigerant lines for any visible leaks. If you suspect a refrigerant leak, it's advisable to contact a professional as handling refrigerants requires specialized knowledge and equipment.



Blocked or Dirty Filters:

Clean or replace the filters to ensure proper airflow and cooling efficiency.



Sensor Issues:

Check if the sensors are working correctly and are not sending false signals causing the chiller to shut down.



Pump Problems:

Inspect the pump for any blockages or malfunctions that might be hindering the flow of the coolant.



In case the issue persists or if you're unsure about handling any of these tasks, it's wise to seek professional assistance.

Check the door frame for a protruding small lever that gets pushed down when the door closes. If one is visible, that should be the light switch, which probably went bad and needs to be replaced. Without a model # hard to say how the light are set to go off, but most use the above method, hope this helps.

Try Defrosting the refrigerator sometimes the water may appear visible in the hoses but may actually be frozen in the inner housing. I had this problem and when I shut my refrigerator down and allowed it to defrost it solved the problem.

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

You have a bad thermostat ( the piece where you adjust the coldness of the refrig ) . Once it gets to temp and shuts off , it will not tell the system to start again . Next time not running , tap on the t-stat . If it starts , this tells you the thermostat is bad .

Look for any tilt in the icemaker towards left, if so loosen both the screws, balance the icemaker.Then tighten the left hand screw first followed by right hand side

p.s the screws will be holding the ice maker with back wall, once you remove the ice bucket it will be visible

the solution is get rid of it fast , i had a samsung dvd player that did that then it caught on fire , pretty scary,lucky i was there when it started to smoke up

check that the condenser fan is working and condenser is clean.. check that the evaporator fan is working may have to push switch in to make it run. if ice is visible behind rear freezerwall you do have a defrost problem find defrost timer and with a flat head screwdriver turn it until you hear a click and everthing shuts down. if yoou hear ice cracking you have a bad defrost timer(very common failure)you may have problem in the defrost heater but you might find that a little over your head and a repairman might be the cheapest way to go, because buying parts can be expensive and they are not returnable

my ice maker is not working. It gradually stoped working

The control knob more than likely operates a relay that has gotten stuck in the energized position. If this isn't the case then the Temp sensor or thermostat probably shorted internally. Unplug the unit before attempting any work.
