There are a few different calculations depending on the type of evaporator coil. There is a forum at http://www.refrigeration-engineer.com where you may be able to find better answers.

SOURCE: evaporator coil freezing, replaced main control

It is possible you have a defective fan motor in the condenser area or evaporator area. Sometimes when they become defective they will run for a while and just warm up and stop while the compressor continues to run. I learned that one on four costly returns to the home. The cost was to me not the customer. Thanks, Sea Breeze

Guidance in replacing an evaporator coil for a Carrier Model 38GS014300


If it is still operational, I would leave it alone. The tools you would need would be an ocy/act welding pack, a vacuum pump, pipe cutters, and if the unit is R-22, you will need to close the king valve on the condensing unit high sidle (little pipe), and push the contactor in to remove all the refigerant in the line to store it in the condensing unit. To know if it is evacuated, you'll need a set of refrigerant guages. Depending on how much you want to spend, it would be cheaper to have someone come out and do it. The parts I have listed can run you upwards of $500. Plus, you'll need to know what your doing so you don't damage your compressor after changing your coil. You'll also need to replace the dryer once you open up the sealed system.

Suction pipe is still freezing up on my walk in freezer


That is most times caused by a restriction in the flow of air over the evaporator coil inside your walk-in. Restrictions will include no defrost taking place or a defective evaporator fan. If low on Freon the ice would only appear at the evaporator first and then reach the suction side of compressor once the evaporator blocks air flow completely. Defective expansion valves can show up with about the same symptom's. If you have more questions let me know and if you should see your model number of the walk-in freezer please list that number so I can get a picture of just what you are working with, Thanks, Sea Breeze

I have had a repairman look at this refrigerator and he claims there is a slow leak. Can't a new freon line be installed?


Usually it takes too much labor to fix that line, Kitchenaid built in refrigerators have capillary tube which licks at the back by suction line tube. Refrigerator will need ti be moved out from cabinet in most cases. Tech would want to give You a warranty, so they usually would replace the whole sealed system for big money, but most likely it last 10-15 years. If They will fix one pipe, next year You might call him back, leak might be in different pipe, but it will be the same expensive (due to labor). Check my video out. A Year ago found leak at evaporator, explained to customer better to do the whole system, but he wanted only evaporator replaced since its so obvious. Now we will replace the whole system, Evap is ok, heater too, but now, capillary tube + suction line + drain pan heater loop(freon pipe). If You watch video thru till the end, you will see where heater on old evaporator touching evaporator coil in multiple bents.

Unit is freezing the products. What should the unit be set on for normal refrigeration?


The evaporator drain pan is blocked with dirt and the standing water freezes along with the evaporator coil. Unplug unit, and when thawed blow some compressed air through the drain pipe. Plug unit back up again and it should be fine.

The lines freeze up outside and then it shuts off


When the refrigerant piping ices the cause is usually low or refrigerant (Freon is Dupont's name for Refrigerant) or the evaporator coil is not getting enough air flow thru it. It would be best to have a qualified technician test your system.

Ice forming and freezing in the freezer bottom


Need to find out if the refrigerator is going into defrost normally, about every 8 to 10 hours. If it does defrost normally, does the drain inside the freezer panel and under the evaporator coil drain without blockage? Defrosted ice, (water) should go down a drain pipe and into a pan near compressor. Let me know, Thanks, Sea Breeze

Groaning noise on GE side by side refrigerator


Hello Michael,
Thanks for your question, I hope I can help some. My answer is long winded but full of good info.
The noise could be as the GE guy said refrigerant (gas) noise. If it is refrigerant noise it happens as the liquid refrigerant comes out of the tiny capillary tube and enters the evaporator (cooling) coil in the freezer. Along with the liquid coming through the capillary tube there often are gas pockets. The flow of the liquid and gas pockets into the evaporator coil cause strange sounds. If the noise you are hearing is this refrigerant noise, you should only hear the noise while the compressor is running and then only for a short time (1 to 2 minutes) after the compressor shuts off.
If the noise continues after that I do not think it is a refrigerant noise.
There are times when the compressor will not be running but the fan in the freezer will be running on this model. This is normal and working properly but if the noise is present when the freezer fan is running and the noise stops when the freezer fan stops, the likely cause will be the main board located in a square panel on the rear of the refrigerator above the compressor compartment. I know that sounds crazy but the main board can cause the freezer fan motor to make some really strange noises. Eventually the board will probably fail.
One other test would be for you to listen for the compressor to turn off, then if the noise is present after the compressor turns off, you would next unplug the refrigerator from the receptacle. If the noise continues with the refrigerator unplugged it must be refrigerant noise. If it stops, I am betting on a bad main board.
I tried to locate for you information on a material that Whirlpool and Frigidaire as well as some others use as a noise deaden-er that they wrap around where the capillary tube enters the evaporator. I was not successful in locating anything. I am sorry I could not find it.

Jenn air jcd229key restricted


the system carries oil around naturally but sometimes it will pool up in the evaporator area causing a restriction at the restrictor/capillary tube. the fix is to recover refrigerant flush the restrictor tube with nitrogen replace the drier evacuate the system and recharge with recomended amount of refrigerant.
