Gold Star window A/C R5207Y3 Evaporator ice buildup

Have had this unit for about 5 years, recently the front of the evaporator freezes over with ice and cooling capacity is lost. Followed troubleshooting guide to reduce thermostat setting and this worked but as soon as I turn the thermostat back to cool the ice forms. Is she just tired or is there something else I can do?

Thanks, Bill

    I'm also getting ice visibly on a lot of the fin area & coils. About half the fin area doesn't have ice. I've been suspecting low freon since spring before this started anyway. The air didn't seem quite as cold & was staying on longer & it's a very old unit that has needed a top off every one in a while in the past. It must be 5 years since I've called someone.



    Earlier I cleared the overflow tube out, but that was a wasted effort. It did seem to be running slow.



    I just hope the repair man will be willing to top it, instead of insisting on a new unit or leak testing. It is a slow loss.

    i have the same problem, but the ice covers the evaporator, almost completely, and the coils on both the right and left side......i never tried to turn the thermostat down? or was it up? i also dont know where the "overflow tube" is either. i also don't know if a few of the fins being bent has anything to do with the fact that the air blows cool, not cold anymore. how would i know if the freon is low or not? please help me, summer is around the corner, and i cant stand the heat. mahalo!

This is njormally an issue with oversizing but this should have manifested itself the 1st time you used it, unless you have relocated the unit. If you have reinstalled it in its original location and if you have cleaned the coils as required, then you have a low freon issue that only a professional should resolve.
Tip: If the ice is building up in 1 small area and not evenly across the complete evaporator coil, then you definitely are low on freon.

My whirlpool acq128xp0 runs great one day, then barely starts the second day, It doesnt have the air volume or cooling it use too. Just started this year. Mike


Mike, when you stated it barely starts, to what are you referring? The compressor (condenser) section has an issue when starting or the indoor fan is hard to start?

If the fan does run, and the condenser unit outside is operating and you are getting lower than usual air flow (compared to previously), you may have a dirty filter, or you may have other obstructions at the evap coil inside the furnace or air handler. It could also be the unit is freezing up and ice on the evap coil is cutting down the air flow. Chances are if the coil is freezing over, you will have two issue that cause this:

Air flow issues (dirty coil, clogged air filter, or other obstructions across the evap coil, such as a plastic bag or pet hair, dust, ect.) which will also cause the coil to freeze over.

The other issue that would cause the low air flow is ice that is a result of low refrigerant.

If the system ran fine in the past, I will rule out it may be inproperly sized. Have you recently had a fan motor replaced on the indoor unit. If so, and they under sized the fan motor, then it could be the fan is not drawing, or blowing enough air across the evaporator coil and this will cause it to freeze over.

Look for ice on the suction line (piping) which is the bigger of the two lines coming from the outside unit (condensing unit). It is also the line that has the insulation covering it. If it has ice on it, then freezing is occuring on the evaporator. If so, then airflow issues, or refrigerant levels are usually the main culprits.

The two lines (suction and liquid) running between your indoor and outdoor unit should feel the following way to the touch of your hand:

Suction should be cold and possibly sweating if exposed (in places where no insulation is present).

Liquid line (smaller line) should be warm to the touch, but not too hot, or too cool. Should feel close to the outside ambient temperature if felt by hand.

Look these issues over and let me know.

FREEZING UP AND BLOWING ONLY COOL AIR


Hi, when your unit starts to freeze-up on the indoor unit and on the suction copper line on the outdoor unit, this is due to a loss of freon. Because in your case, the air is not as cool as it should be or normally is. Some will ice up if the filter has not been changed on a regular basis, and the evaporator coil gets plugged with dirt. When it starts to ice over, you will loose 50% to 95% of your air flow. As long as you have good air flow, but not as cool with the ice ( you will loose some air flow if its been iced up for awhile ) you have a very small leak in the system and will need a recharge. They will normally leak at a place of least resistance like at the schradder valve where the freon is put in. If you have a older system, it may be in the evaporator coil. It depends on how much you have lost. You will need to call out a licensed tech to charge this unit. This is your problem indeed. Please keep me posted and informed on this. When you rate me, please be kind as I know you will. I thank you for this.
Sincerely,

Our Quietmaster 's cooling works for a while and then doesn't.


Remove the front cover and make sure the temp sensing wire is in place on the front of the evaporator coils. If it has fallen and is touching the evaporator plumbing the unit can preform as you described.

Also check for signs of icing / ice build up on the evaporator coils after the uint has run for a couple of hours. Ice build up will also cause this symptom. IF you do find that the unit is icing up that can be caused by:
1. A very dirty evaporator
2.. A clogged Air filter
3. Contaminated by internal plumbing debris / clogged freon passages
4. A blower Fan motor running to slow.
5. Freon Pressure and return lines touching together usually either on the side of the unit or just behind the center chassis air wall enroute to the compressor.
6. A corroded electronic control board.

As you can see above there are several things that can cause the symptom your described. It cetainly sounds as if you either have an icing problem or a control board problem.

The next time the symptom occurs... place the unit of fan only for at least 30 minutes and then see if you can switch it to cool, and actually have it cool. If it does cool properly after switching to fan only for 30 minutes you most likely have an icing problem.

Thanks for using FixYa.

My Coleman rv mach3 63134cst which is about 3 years old won't cycle and freezes up when it runs to long. Ice forms on coils.


If coils are clean, or have been cleaned recently, then check your discharge side of unit for restriction. It may require you to take down ceiling assy, to be sure that there is nothing blocking the duct work inlets, if it is a ducted system. Also if ducted system, make sure you don't have too many blocked/shut off. As well you should have a freeze probe, or round sensor in the coils at front where intake filter goes over, (evaporator) to sense the frost, and kick compressor out until it thaws. When was the last time the evaporator and condenser (rear) coils were cleaned?

18 year old Janitrol Heat Pump freezing up.


i would get someone to check your refrigerant levels have you ever had the evaporator coil flushed and cleaned? proper refrigerant levels and proper airflow across coils are extremley important not to scare you but 18 yrs is a long time on a heat pump 9-12 years is the point where they really loose there efficiency going for a newer one would probably cut your operating cost in half if not more depending where you live there are a lot of people not familiar with heat pumps so i suggest finding a company that specializes in them to service your unit

-1 evaporator need cleaning
- 2 a smll freon leakage

Formation of ice on evaporator element


hi! there,
eventually ice freezing evaporator occured two factor you have
dirty fin evaporator and undercharge system.
1. undercharge can easily detected using clamp
ammeter clamp on one line of evaporator while running
read the amper the compare this to yuor service
manual the rated current of the compressor.

2.if the reading current is below the rared current on
manual or there is tag on the body of unit specified
rated current.your unit need to recharge.

if has the same current no change at all freon is still
good, this only need cleaning of eveporator fin.

clean this by pressurise water to purge out all debris
particle on fin tube of evaporator.

cracking sound usally made by blwer or fan
misalignement or distorted bearing blower .



regards have anice day dont forget to rate me.

LG LWHD1800R air conditioner problem


It sounds to me like the compressor is overheating and tripping on internal or external overloads. After the unit cools down again it will try to run for a little while. Then this cycle would start over. I would check the condenser coil for dirt and filth. This portion of the unit may be on the out and backside of the unit. You should at least be able to see light through the coil.

I believe the thermistor that you removed temporarily is used for a freeze situation. I do not believe that it is your problem. Good luck:)

Ac ices over


First you need to make sure the filter is clean to allow good air flow through the evaporator. If the filter is clean make sure the evaporator is not plugged up with dust and lint. If all that is ok your problem is the a/c BTU's is to big for the size room you have the a/c in and it is getting the room too cold. If that happens the evaporator will ice up and will not cool the room.
