In winter the outside unit sounds like a rubbing/ticking noise


Sounds like ice coming of the coil. That would explain the ticking. The rubbing could be ice buildup before the defrost cycle or it's building on the blades of the fan throwing it of balance a bit.

Why is our EuroCave DUO wine cooler model D264 freezing 1/4 inch of ice on back wall inside cooler?


Most cases of ice build up can be traced to seals that leak humid air into the cooler. Check the door seal carefully using a fresh $1 bill. The bill should not pull out easily when the door is closed. If the unit has a self defrost feature it it is not coming on. Ice buildup inside a wine cooler is very rare. The cooler box should not reach 32deg in normal operation. Does the unit seem to run continuously?

GE GSL22JFTABS Frost buildup on back wall of freezer and ice maker not making ice


Your unit is not defrosting, causing the unit to build up ice and not allow the air to flow. There are 3 possibilities, listed with the most likely first.
1. The DEFROST HEATER in the freezer section, just behind the cover along the back wall of the freezer.
2.The DEFROST BI-METAL which is just about the HEATER, it is a small round thermostat that keeps the HEATER from getting too hot
3. If both of those parts are good, then you have a bad MAIN BOARD. The board regulates the defrost cycle, which replaced the older defrost timers.

Frost build up


Hi

Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt. Determine the temperature setting. The refrigerator should be set to temperatures ranging from 34 degrees to 40 degrees, while the freezer should be below 30 degrees. Adjust the temperature setting which will naturally improve the ice buildup that's been caused by the wrong temperature setting.

Move the refrigerator away from the wall. Oftentimes, this simple action is all that is needed because the unit is not getting enough air circulation behind it. Also, some refrigerators have vents underneath the unit, which are easily clogged with debris. Clean these vents and coils.

Remove food and shelving from the refrigerator and freezer portions of the fridge. If ice build up is happening in the freezer, the drain in the freezer may be clogged. With the unit off, remove coverings to expose drain and pour hot water down the drain hole until it comes out into the drain drip pan under the fridge.

Check the condenser coils. The evaporator coils could be causing the problem of ice build up. If this is the case, professional repair is likely needed to replace the motor, thermostat or other problems within the fridge.

Ice coming from unit?? WHy would ice be "spitting" from front indoor wall unit


The unit has frozen up, and the fan is blowing out small particles of ice.

Freeze up is due to Improper airflow, and/or low refrigerant charge.
In the case of a heatpump, it can also be due to a malfunctioning defrost cycle.

Most likely, the filter and/or coils are dirty, causing an air restriction. I'd reccoment cleaning both coils and the filter. Let the system defrost, and run it again. If the problem persists, you have a refrigerant problem.
(or a defrost issue with a wall mount heat pump.)

Friedrich air conditioning - inside unit ice build up


Hi, Reduced air flow, low on freon or being continuously run during cooler weather such as at night. Some people turn their thermostat on 60 thinking that it will help get it cooler faster. They freeze up at night and don't get a chance to thaw during the day. It needs set no lower than 75 or so. The evaporator may be dirty. Don't know a lot about your particular unit but if the outside unit has the compressor and refrigerant lines running to it, The large refrigerant line should sweat all the way to the compressor if its fully charged. Please rate me if I have helped. Good luck kstfas
