Fridge section has ceased to work, no longer stays cold.


Check Warranty? Some parts of the refrigerator may have extended warranty.

Likely one of two problems. Either the defrost cycle is not working or the cooling is not working.

Look for ice build up inside around the back of the unit.
26160077-ai3unifkpfov1uv0qrlw5ags-5-0.jpg If ice has built up on the back wall it is a sure tell that the defrost cycle is not working and the air flow is restricted by the ice built up around the cooling coils resulting in not cooling.

First try would be to empty the unit and allow with the doors open 24 hours with heat to melt the ice. Afterwards start normally and hope that the problem doesn't return. There is a tube that needs to thaw from the bottom of the coils that is known to freeze preventing a satisfactory defrost. This tube takes time to defrost if frozen closed.

If problem returns in a day or two then more troubleshooting is required. The heater, defrost sensor and depending on the model, timer may need to be replaced. This is far less expense then replacing the unit and I would be inclined to repair the unit.

No ice built up on back wall of unit does not mean that the defrost cycle is working so check for air flow coming out of the vents. If the air flow appears to be restricted it still could be frozen cooling coils and requires defrost.(see above)

If defrost is not the culprit than reread the warranty. It is likely the unit has a leak and the Freon is low or the compressor is failing. Check the fan located at the bottom from the rear or check for airflow from the front grill. Remove grill and check for massive lint and dust build up restricting the airflow before deciding to replace.

The cost of leak repair or compressor replacement can exceed the present value of the unit and could be better applied against the cost of unit replacement.

Hope this helps?

When I open the door to my kitchenaid superba freezer the air blows into the refrig but as soon as I close it the cooling stops. What could possibly be the problem?


Hi,

You have a restricted air flow. This can be caused by the doors being left open. 3/4 down in the refer section you have an air vent (usually around the crispers) this air channel is clogged either by ice or product in front of the air return. Once this is cleared your air flow should return. Best way to de-ice this is to turn off the unit and allow to thaw. But most people need the speedy way and be careful if you elect to use a blow dryer as the heat can melt or deform plastic. I hope this helps, good luck

Why is my brisk air duo therm rv ac freezing up on the inside.


Where you see frost all the time, wait for unit to thaw and start cooling again and carefully slide hand up in that hole and see if you can feel cool air leaking in from divider that separates cool and return air, that will cause freeze-ups as well. Use foil tape if necessary to stop any cool air coming in to return air from around divider. Also, if you have any diffusers closed, (on ducted system in ceiling) or partially closed, open them all up full flow. If you restrict the cold air from coming out too much, it can also cause freeze up. One more thing, take cover off where cool air box is and double check that something isn't restricting the flow of cold in to the duct work if it has ducted system.

Our window-type airconditioner never gets that cool and when we remove the front cover, its all covered in ice....what should we do ? thanks


Problem is most likely the de-icing switch, a thermostatic device which cuts of the compressor when the evaporator gets below a certain temperature -- the de-icing switch is not opening, the compressor keeps running and the unit ices over. With ice on the evaporator, air does not flow over it, and the unit does not cool the room.

More info, let me know.

If your fridge is left open over night and it wasnt closed till morning and the alarm light does stop flashing when it is closed what does that mean?


Hi and welcome to FixYa, I am Kelly.

FYI... The door alarm will sound anytime the door is left open for more than 4 minutes.

Per your post... What it means your refrigerator is working normally.

However... there is the possibility of having excess ice build up on the evaporator coils from the door being open all night. If the freezer section starts warming up due to poor airflow you may have to do a manual defrost. You would first notice the lack of ice production or soft ice cream if there were air flow problems due to excess ice on the evaporator coils.

To do a manual defrost all you do is:
1. Unplug the unit
2. Remove freezer contents
3. Use a fan directed at the freezer compartment for just over 2 hours (makes a water mess)
4. Reload the freezer
5. Plug in the refrigerator

Everything should be back to normal in just over 4 hours except ice production that can take up to 8 hours.

Thanks for choosing FixYa,
Kelly

Water leaking onto ice and outside panel on Hoshizaki KM-500MAE


Remove the cover where the persons finger is and check to make sure that it is not covered with ice. Sounds like your machine iced oup and you will need to clean the coils and possibly replace the thermostat

Thaw's. Turn-off for period of time it would freeze as normal


Make sure nothing is inhibiting air flow. I don't think it is advisable to store food in an ice machine however that is not likely the problem unless the food itself is inhibiting air flow. Most ice machine manufacturers recommend against storing any food in an ice machine. If there is a freezer component in you model the check to see if the evaporator coils are frosting up and the frost is blocking airflow causing the ice storage chamber to get warm. High humidity can cause frosting. Leaving a door to the ice maker open too long can cause frosting. A low refrigerant charge can do this although it seems logically like it should not. With a very slightly low charge one end of the evaporator gets super cold and the other end is not cold enough. Frosts starts collecting on the super cold end and accumulates across the evaporator coil to the other end eventually blocking all air flow. With too much humidity from open doors frost accumulates over the entire evaporator evenly but still blocks. You shut the unit down. It thaws out and works OK on restart until frost again builds up. If its not a frosting problem but it just stops making ice then the ice may not be releasing. Check the water supply and change any filters to insure good water flow. A good water supply is required for proper release and harvest of the ice in many ice machines. If the ice doesn't release it takes a shut down and thaw to clear the suspended ice out. Check for these things and write back if you need further assistance and can provide me with more details.

Ice in the unit


Welcome to fixya.
I'm Huuum and happy to assist you,

You said, Left house for a while with unit running and when I returned little or no air was emmiited from unit, and when I removed back cover, solid sheet of ice!


Sounds like you have a coolant leak or the thermostat is malfunctioning.
You need to have the freon checked first to see it is not low.
This one reason that will make it freeze up .
let me know how much freon it took.

Please remember to leave a rating before you go!
Thank you

Samsung window air conditioner model aw05ncm7 icing up not cooling


After I opened the front of the unit and discovered it full of ice, I left the unit off until it defrosted, so to speak, after the ice had melted, I turned the unit back on to see what happened. It is working fine now, I'm not sure why it iced up, if this is normal or not, but after it melted the problem was solved.
