SOURCE: why suction line would ice back

Good day,
Unusual question.
Lots of reasons. You didn't say if it was cooling or cycling off and on.
1. Evaporator fan motor in freezer compartment not running. Doesn't allow the refrigerant to boil off and returns as a liquid.
2. Evaporator coil badly frosted allowing no air flow thru it. Same as #1
3. Runs constantly (days). no demand on system, and once again will not boil off before leaving evaporator.
4. Overcharged. Floods back excess charge.
5. Heat exchanger came apart. The capillary tube is soldered to the suction line to transfer heat from the cap tube to the suction line. Necessary on a refrigerator. Common problem.

Hope this helps
Thanks for using fixYa

My Kenmore side by side fridge isn't cooling hardly. Feeling the suction and discharge lines I think it's low on freon. How do I charge it?


Well I have to go, so I can't wait for your reply for more info. Basicallty what happened to me was the freezer became very good at freezing. The problem with modern freezer/fridges is that there is only one cooling system, the freezer. The freezer chills the other side to chill the refrigerator. Something was blocking that vent into the fridge side. Turns out it was ice blocking the vent into the refer side. It happens when it is humid and the kids to "shopping" in the fridge and leave the door opened for extended periods of time.

If you are blocked by stuff in your fridge, move it away from the vent. If nothing there, you'll need to get ready for a bit of time. Side-by-side freezer/fridges, typically the freezer is on the left. So, open the fridge, somewhere near the back about 2/3s of the way down, just above the vegetable bin, on the left side. Remove the cover, if something is stuck in there, gently try to remove it. If it is ice, like I had, you should remove your vegetable bin and meat bin and unplug the unit (to prevent shock as water will be everywhere. Be sure that your overflow tray (under the unit) is empty. Next is to make quite a bit of boiling water (I ended up using just over a gallon). If you are at the point where you can't get the cover off, you'll have to use a baster to melt the ice that is holding your vent cover on (that is where I started). Then you can start working on the ice. You need to keep putting water in until you get hot water in the overflow tray. Replace your food and don't slam the fridge control all the way to the coldest setting, you could end up freezing your meat and vegetables.

The repairman came and told us, he could do this for us for $200 or we could do it ourselves. He would have done the exact same thing.

Ice on suction line


hello, usually the suction line will form ice when there is low airflow due to a dirty filter or plugged eveaporator coil, also if the unit is clean then it is possible that the unit is low on refrigerant charge due to a leak. Inwould also check the thermostat on the unit to make sure it is fuctioning properly, I have seen may units where the thermostat cause the compressor to run continously and cause the suction line to freeze.

Great site! I have a 2000 GE refrigerator model CCC18HABDWW (made in Canada). The suction line that goes 1/2 way up the back ices up. Then when the fridge shuts off the ice drips all over the floor....


Good day,
The tech overcharged the machine with too much freon. Common problem.
Refrigerators are extremely sensitive to charging. The machine as it is running and the frost building up on that line, freon should be bleed off but only until the line goes clean. It's a slow tedious process since if too much is removed cooling will suffer.
Patience is the key here. I doubt dirt in the condenser is an issue at this time but cleaning it can never be done too often.

Model # PSC25PSTBSS low pressure tubing icing up on compressor ref @ 42F has A valve on the high side for cap tubes


Very unusual for a household fridge, but ice build up on the lp side(suction) normally indicates to much charge (gas) in system or if compressor starts to become less efficient, valves dont seat 100% which causes a liquid build up on the line. If the evaporator fan motor stops, this can also create that problem.(assuming the fridge wasnt cooling properly). Many occasions when a new compressor is installed, the technician might put a little to much charge in by mistake. Normally a machine puts in an exact amount that has been dialed in.

1. First check if your door rubbers seals properly. if not, try and adjust yor doors so that they seal properly.what happens sometimes is that moisture leaks into your fridge.
2. It is also possible that your unit is overgased. you can buy yourself a valve that can be screwed onto the suction pipe line to your compressor. at the back of your fridge you will find a condenser unit that is directly connected to your compressor. that is called the discharge line and you will notice that the discharge line is thinner than the suction line to your compressor. get yourself a set of fridge gauges that you will connect to your valve that you just connected to your suction line. check your psi reading of your suction line under normal running conditions. to get a compartment temperature of minus 18deg celcius your psi reading depending on gas your fridge is charged with should be more or less 4,5 psi. if you have ice build up at the back of your fridge on your suction line your unit is overgased. if your reading on your guage reads less than zero psi then your unit is undergassed. good luck.

The condensate drain may not be draining into the pan under the fridge or it may have a leak or could even be not connected to the condensate pan in the evaporator.
Another possibility is that your condenser might be dirty or plugged causing the suction line going to the compressor to freeze up and then thaw leaving puddles under the fridge. Clean the condenser (the coil under or behind the fridge) and it should stop.
Over stocking the freezer will cause this as well. If you cover the air return in the freezer the evaporator will freeze up and the suction line will freeze back to the compressor.

Water leaking from freezer into fridge


there are several things to check for. The condensing defrost tray under the fridge can crack or develop a hole and leak onto the floor. A door gasket not closing properly may cause sweating and leak onto the floor. Some fridge's have a humidity switch inside the fridge that should be turned on to prevent sweating on the center bar between the fridge and freezer section. If your fridge has developed a frost free failure problem, often the frost will travel down the suction line at the back of the fridge and drip water on the floor. The heat exchangertubing can separate and also sweat and drip on the floor. A kit to repair a separated heat exchanger line, comes with instructions as well. Ice maker and chilled water fill lines can crack and leak as well, this is fairly common with the plastic lines as they can dry out and crack.

The copper line under my s. b. s. fridge keeps freezing


the line that you ae seeing is the suction line . It sounds like the defrost timer may have gave up the ghost on you and the unit is not going into defrost. Take the model Number and make to the local parts house and have thenm get you a timer. They are real easy to replace and that should take care of the problem.
