Question about U-Line 75WC Wine Cooler

Open Question

U-Line 75WC not cooling-

Compressor, condenser fan, light, all appear to be running fine, but system is not cooling. Does this unit have a defrost cut off that may be frozen open? Could t-stat not be working if it is telling compressor to run? Thanks for the help!

    I don't believe you all read my first question thoroughly- the compressor is running! It's not cooling though, *so* I'm asking why it may not be cooling if the fan and the compressor are working?

SOURCE: replaced control on u-line 75WC wine cooler now runs constantly

If the sensor of the thermostat is not on the evaporator plate then yes the thermostat will never be satisfied. Because it is not reading air temp only the evaporator plates temp. should be clamped onto the bottom of plate.

GE Profile French door not cooling 70degrees


The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem.

in other words is there ice frozen all inside if so unplug and take a hair dryer and melt the ice thouroghly

Tip

Why your unit is freezing up.


To understand why your AC or heat pump is freezing up, it helps to know how your system works.

There are 7 major parts to an AC system, 9 with a heat pump.

1 - Condenser/heat pump (The outdoor unit)
2 - Air Handler (the indoor unit unless the system is a package unit, then all is outside in one system. The air handler is usually found under the home, in an attic, or in a closet.)

In the condenser are the following major parts.

3 - Compressor
4 - Condenser coil
5 - Condenser fan
6 - (HPs only) reversing valve

In the air handler are the following major parts.

7 - Blower motor
8 - Evaporator coil
9 - (HPs only) electric heat strips

Some systems known as "dual fuel systems" use another heat source in place of the heat strips, usually a gas furnace. I will address gas furnaces in another post.

When an air conditioner is operating properly several things are taking place.

1 - The compressor is compressing or "pumping" refrigerant through the system.

2 - through changes in pressure, the refrigerant makes the evaporator coil get very cold, and the condenser coil gets very hot.

3 - The blower motor/fan circulates air across the evaporator coils, as the room temperature air (Also known as "indoor ambient") goes through the cold coil, it exits, cooled approximately 15 to 20 degrees cooler than when it entered. (In a ducted system, the blower is also the fan that circulates the air throughout the home.)

4 - The condenser fan circulates air across the condenser coils. As the outdoor air goes through the condenser coil, it removes heat from the coils that are very hot. This in turn removes heat from the refrigerant so it can run its cycle again, and through pressure changes, cool the evap coil.

5 - With a heat pump, the reversing valve reverses the flow of refrigerant in the condenser and evaporator coils.
In AC mode, the evaporator coils get cold, and the condenser coils get hot. But in heat mode, the evaporator gets very hot, and the condenser very cold.

Now, whichever coil is getting cold will freeze up if there is inadequate air flow across the coil, as the refrigerant in it is far below freezing, and there is not enough airflow to keep the humidity in the air from freezing on the coil.

Things that can cause poor airflow are,

1 - Dirty/clogged coils
2 - dirty/clogged filter (will only effect evaporator coil)
3 - Closed/blocked vents (will only effect evaporator coil)
4 - Malfunctioning or dirty fan

Low refrigerant will also cause a coil to freeze up, reduce efficiency and cause the system to run for long periods of time. Not to mention, shortening the life of the unit.

With a heat pump, in heat mode only, the condenser (outdoor) coil will routinely begin to freeze up in cold temperatures. This is due to the fact that the refrigerant is below freezing, and the cold outdoor ambient temp is not warm enough to keep the condensation in the air from freezing on the coil.

Note, a properly working AC should never freeze up.

A heat pump is equipped with defrost controls to prevent ice buildup.
Some are controlled by timers, some by temp.

When a HP is going into defrost mode, the condenser fan shuts down, the reversing valve reverses the flow of refrigerant and the once cold condenser coil now gets very hot, defrosting the coil. (Many people have said this process sounds like the unit is coming apart, or about to explode and are frightened by the "smoke" which is really just steam from melting ice that comes off the unit.)

During defrost mode, the secondary or "auxiliary" heat comes on to ensure that you are still getting warm air from the vents. (Again, this can be electric heat strips or a dual fuel system)

If you are experiencing cold air from the vents during defrost, that means your auxiliary heat is malfunctioning.

The auxiliary heat is used for three purposes.

1 - during defrost mode to maintain warm airflow (automatic)
2 - when the HP cannot maintain the set temp due to extreme outdoor temps. It comes on when the indoor temp drops several degrees below the set temp on the thermostat (automatic)
3 - For emergency heat source when the HP is not working. (Manual)

To recap....

Iced up coils?

Poor airflow
low refrigerant
Malfunctioning fan
failing defrost system


There are two things that can be done in a pinch to help de-ice frozen coils. This may get you by until the repairman can get there, or you can fix the system if you are a do-it-yourselfer.

HPs frozen outdoor coil in heat mode, not going into defrost?

Cover most of the vents, and turn the system onto cooling mode until the outdoor coil is thawed. then uncover vents and return to heat, or emergency heat. (this usually takes 15 min or less)

Frozen coils in AC mode with a heat pump?
Turn the system to heat with the thermostat on just high enough to get the system to come on. (again, usually takes 15 min or less to thaw.)

AC only, with frozen evap coils? (this can sometimes be seen frozen all the way outside to the compressor on the copper lines.)

Turn the system off, and the fan switch from "auto" to on".
This will usually defrost the coils within 1 to 2 hours.
(If your system has the furnace in line before the evap coil, turn the system to heat, and the furnace will defrost the coil within minutes.)

Hello;

My name is Peter. I am a retired field service refrigeration technician.

I am going to assume your compressor and condenser fan is running. Your condenser fan is in the lower back of your freezer.

You will need to remove the back cover in your freezer. There are 6 screws holding it on.

Check the following (Cover Removed):

1.) Frozen Drain - Your freezer goes into a defrost mode every 8-10 hours, where your freezer shuts down except for the lights, and your defrost heater turns on for about 20-30 minutes to defrost your cooling coil. If you have a frozen drain, the condensate builds up behind the back wall and icing the cooling coil, restricting air flow. You must defrost the coil.

2.) Freezer Fan Motor Failure - Having removed the back wall observe if the freezer fan motor is running. If not replace.

3.) Refrigerant Restriction or Leak - If you observe a large build-up of ice in the upper right hand corner, then you have a restriction or leak. The cost of repair would be about $400.00

4.) Bad Thermostat - In the upper right hand corner of you cooling coil, attached is your thermostat. They can explode, where the back of the thermostat will raise up.

You can also check it with a multi-meter, set to the lowest Ohms (Omega Symbol). You need to cut the wires, leaving enough wire length to rewire back in. Put the thermostat in a glass of ice water for 10 minutes. After, it should Ohm out around 16. It is reads '0' or infinity it is bad. Below 15 or 16 it is bad

Not cooling


Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. The relay is a small usually black cube shaped electrical part plugged into the compressor or wired to it nearby. It may appear burnt or rattle when shaken if it's bad. The two connections should show continuity with an amp meter. If it's good then it's most likely the compressor causing the problem.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm




Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).
If it's iced up really heavy you have an auto defrost problem. Melt the ice with a hairdryer and check the defrost system.

Unit not cooling down,compressor running,condenser fan running. suction line just cool,condenser line barely warm.


Check if evaporator fan is running. Is there any frost buildup on freezers evaporator cover? If so you have a defrost problem (bad heater, defrost thermostat, thermister, defrost timer or circuit board ). If no frost and the freezer is warm then you most likely have a sealed system problem(leak, restriction, bad compressor) which is costly to repair.
