SOURCE: system does not go into defrost

Did you check the solenoid on the reversing valve? Has the compressor ever been replaced?

Most reversing valves are normally in heat pump mode, and when the solenoid is energized, it is in A/C mode (in summer cooling, the valve is energized.). If the solenoid is bad, then the unit can not switch to defrost.
If the compressor has been replaced, there is a chance that the reversing valve might have some trash in it, preventing it from switching over. Lightly tap on the valve when defrost or A/C mode is being asked for.

SOURCE: Unit will not go into defrost.

There is a good chance, if the defrost timer is mechanical, that you can rotate (nudge) the timer to see if it get's going.

Most commercial refrigeration does not use a defrost thermostat, and a lot of it does not use a heater (they use a hot gas bypass valve and pump hot gas through the evaporator, rather than through the condensor.).

Let me know if you need further help.

Tip

Why is Ice Forming on my Heat Pump


Many people have heat pumps and never realize that ice can form on the outdoor unit. Some have seen ice on their heat pumps but do not know how much is too much until they have a problem with not enough heat. Still others have a backup heat source and never know that they have a problem.

First off lets establish that heat pumps will form ice on the outdoor unit, usually whenever the outdoor temperatures go below about 40 degrees F. This threshold for ice depends a lot on the humidity of the air outside. If it is raining or snowing, the ice will form much more readily and rapidly. It is normal for ice to form on the outdoor unit because it is the cold side of the system when it is running in the heating mode. Because of this cooling, if the outdoor temperature is near or below freezing and there is moisture in the air, it will condense and freeze on the unit.

To keep the ice from building up to the point where it stops all the air flow, the outdoor unit will have a defrost timer board. This operates in conjunction with a sensor. Every 30 – 90 minutes the board will check the sensor. If the sensor tells the board that ice has formed on the coil it will then change the unit over from heating to cooling. This will make the outdoor unit the hot side for a short time to melt away the ice. While it does this, the unit will also energize the back up heat which is often an electric coil or a furnace. This will keep the inside air from blowing cold while the unit is defrosting.
When the sensor feels the coil temperature at about 50 degrees F it will then tell the board to return to the regular heating and switch the coils around again.

If this process fails to work for some reason the outdoor coil will become a big block of ice and look something like this.

When your outdoor coil becomes totally frozen over it stops all the air flow through the coil and stops the heating process. In extreme case it can be very difficult and becomes a very long process to defrost the coil. You need to practice a lot of patience and care when defrosting a badly frozen coil. A torch or preferably a heat gun (hair dryer) can be used to speed up the defrost process. If it continues to occur the timer needs to be set to defrost more often or either the timer or the sensor has gone bad.

Frige not cooling numbers not lite for fridge but freezer temp numbers 567 are all lite. unplug and plug in and both temp numbers r on 4 but u go back and fridge number is not lite and freezer is on 567


If you unplug it you must wait for at least 15 minutes before restarting the unit. This goes for any refrigerator so the coolant system can equalize and the compressor will restart.

There are 3 components involved with this error code. The defrost thermistor, The defrost thermostat and the main control board. Most likely you have defrost thermistor or themostat that is open and the compressor will NOT start because the power for the comprssor has been interrupted by the automatic defrost cycle and nothing is telling the unit that it has completed the automatic defrost cycle so the unit does not restart. The thermistor and the thermostat would be #1 on troubleshooting list. The thermistor will have varied resistance 10,000 Ohms and under and the thermostat is supposed to be OPEN / have continuity above 60 deg F and closed below 60 Deg F. .

If you need parts information I need your COMPLETE model number (Not Kenmore elite)
Example would be 110.11112222 (not your model number and all numbers willmost likely be different) I think your model number will start with 795.something because this unit was made by LG.

Thanks for choosing FixYa,
Kelly

We have A GE HSS25GFPAWW side by side and the freezer doesn't defrost so the fresh food side gets warm. We pulled the panel off and the coils are frozen, the fan works. Could it be the heater coil or the...


Yes very much possible that temperature sensor( defrost thermostat) or heater coils ( defrost heater) is faulty.. If you see, too much ice frost collected there, then its defrost related issue. First try manual defrost reset procedure. The procedure is as follows: ----

First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. Then its defrost board problem. -------------

If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

Sorry to hear about your problem. Sounds like you have a defrost issue. Hence your unit is not defrosting. All of this apply's if your freezer side has ice on it. If not. you have other issues
Here is a list of some things that can go wrong.
1. Defective heat coil
2. Defective defrost timer
3. Defective defrost sensor
You should call a service company to resolve your issue.

Icemaker not working


Try using an hairdryer or defrosting the unit completely , this often get rid of blockage caused by frozen lines fixing the problem.

The water lines can also be unblocked from dirt using a thin flexible shaft. This after defrosting.

If all that does not fix the problem, then you may need to replace the water valve, the icemaker solenoid, or the whole icemaker assembly.

Power on but fridge/freezer not working (only lights)


Yes, boards may need replacing, but not at the expense of the door, apparantly your "engineer" would rather work on older models that may require a hammer. Best advice would be given knowing the make and model number of your unit. A professional should be able to diagnose the board processes as well as the compressor in a short amount of time. Check the defrost heater (after pwr is restored to unit) for the freezer side (placement depending upon model) for continuity (basically a heating element for the evaporator coils - which will freeze without defrost). Proper defrost will help lessen the load on the compressor. Check the overload relay on the compressor itself for failure and replacement of relay. Have the unit defrosted, svc defrost htr, thermostats/thermolinks , compressor, before checking computer board operations.
