FREEZING COILS COILS AND LINES FREEZING AND UNIT CONTINUOSLY RUNNING .

Sounds like the air circulation fan isn't running. The air must be circulating to freeze. First tip off is the coils are iced up, second, unit isn't freezing. Find the fan inside the freezer and check that it will turn and it's not stuck. Sometimes a little 3 n 1 oil on the bearing shaft into the motor is all it takes to get it running again.

Hi Kenneth, I am happy to assist you!

If your freezer is not cooling, it could have a floating restriction in the lines or something more complicated like an issue with the sealed system that only a professional can repair. This can include the compressor not working correcting, the evaporator fan not turning, or even coolant in the lines with incorrect levels to properly cool. Do you hear the compressor running? If the compressor is running, humming or even a little warm then that is typically normal. I suggest cleaning the unit out including the coils you can reach (typically located underneath or behind the unit). Also try checking and see if the door seal is bad; place a dollar bill between the body of the freezer and the door. Now close the door. The dollar bill should stay in place and pull out with a small amount of resistance. If the dollar bills falls out when placed between the gasket and cabinet double check to see if the door is being blocked by anything stopping it from closing. If any of these suggestions prove to be ineffective, connect with a professional to accurately pinpoint any potentially more serious issues.

Best of luck!

CHECK THE CONDENSER COILS UNDER THE UNIT. THEY PROBABLY ARE DIRTY AND CANT REJECT THE HEAT.

major causes of evap.freezing dirty coil,evap fan motor or capacitor low on freon.moisture in system. first turn off cooling run fan to completely thaw unit. if possible clean coils and blower wheel. any unit running efficiently the evap coil will be at freezing or below. the key is to have enough airflow across the coil to remove the heat and humidity.its very easy to introduce air and moisture into the system. i have seen alot of techs. over the years make the same mistakes over and over again. when hooking up guages they dont purge the lines back; worst case is only to evacuate freon pull a vacume and recharge

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

You have a blockabe in the distributor tubing which will need a professional to sort out.

If you are not certified to do H V A C then I highly recommend that you call in the pro's. However there is something you as a homeowner can do. Start by checking the air filter. if it is too dirty it will slow the air flow across the coils and cause the coils ti ice. The line freezing is a sign that your coils are beginning to ice or already have. This is also true if the coils are dirty. You can check this by removing the air filter and using a flashlight to look up inside of the air handler. If they are dirty then you can clean them with a solution of water, mild dish detergent and a soft bristle brush. Be sure to rinse them thuroly. If this does not fix the freezing problem then you may very well have a small leak and need to have some refrigerant added. hope this helps. Good luck.

maybe,it can also be from real dirty condenser coils under the frig.clean your coils and see if this helps,also has freon ever been added to the frig.?

Is the compressor running? Is the coils near the compressor clean and is the fan that blows on the coils running? Does it get cold at all or is it room temp? One thing to do is to turn it on after leaving it unplugged for and hour. First access the compressor and make sure you can feel the copper lines coming out of it. Some have 4 plus a service pigtail. On the ones with 4 will have two lines the same size that circulate oil for cooling the compressor running to a small set of coils. Pay attention to the larger and smaller lines and notice what temperature they feel like before you plug it back in. Once it is plugged in and if the compressor is running less than a minute the small line should get hot, up to 140 degrees F. Check it soon as after a few minutes it can burn you...The largest of the lines is the low side or suction side and it should be very noticeably cooler than room temp and continue to get colder the longer it has been running. If both these things happen, the charge should be adequate, and the compressor is working. I would then check to see if air is circulating in the unit..Are all the fans running when the unit is on? Most common is for the defrost circuit to fail causing the unit to build up ice behind the liner blocking air flow. Unplugging the unit and leaving the doors open over night will let it thaw. Put several towels around the unit incase this is the problem as there will probably have more water come out than the small pan under neath the unit can handle. Once all the water stops dripping out, plug it back in and see if it works correctly. If so it will probably freeze up again and need to be defrosted again. If so the defrost circuit has failed....either the thermostat in that circuit, the heater coils or the defrost timer switch. Switch very common, coils next and the high temp sensor last.... let me know what you find...
