Goodman PCK-060-1C. suction 52, coil/filter/blower/restrictor/drier okay. Recovered the charge and recharged with factory specified amount. The return air 1800 cfm. Motor 3/4 hp. It seems to me the motor can't handle the S.P. Application is a manufactured home. Any suggestions? jc@christianac.com

It seems to me that your suction should be @ 76 or so. 52 is low. the coil will ice up with any suction PSI below 58. Disconnect the unit from the duct work and make sure there is no restriction in the duct size. In other words. Does the unit work properly with out the duct? I find most mobil homes have a restriction in the amount of return. A 5 ton split needs a 20 inch round return. You never see this size return on a package unit. Does the return **** the filter in? I have had to add returns to large mobil homes because there just not designed right.
this is only a possibility. Is the temperature split on the equipment between 18 and 20 If it is then I don't thing you have an equipment problem. Also make sure there are no holes in the duct work.Last one I had unit was working fine but the duct work had a big hole in it from some animal under the trailer.

My goodman unit is freezing up. It is frozen from the line running out of my house than if u look down into unit, the freeze continues inside


Hello, the suction line will freeze either due to low airflow such as dirty air filter, blower wheel, evaporator coil or a weak blower motor. Also, a low refrigerant charge can cause the suction line to freeze up.

There should be a name plate with the model and serial # which will tell you what the factory charge is for the unit plus 15 to 25 feet of line set. If you weight in the charge you should be pretty close...... In AC mode you should run around 125# suction and about 265 head pressure with 70 degree ambient F. If you have the right charge in the heat pump and you are still running 25# suction pressure in the Air Condition mode then you have a restriction filter drier or TXV locking up..... Did you replace the filter drier when you fixed the leak was the leak on the suction side if so then you definitely need to change the filter drier.

I have a Goodman A/C unit APRF036-00B1. The out side unit seems to be sucking and bowing air, the coil is cool to the the touch and the blower seems to be turning. I've check what seems to be the obvious. A small amount of air is only coming out. Any suggestions?

How to determine evaporator icing problem of air conditioning units


Due to :

1.. Evaparator coil dust blocked. 2. Air filter blocked. 3. Less rpm of fan motor. 4. Short of gas. 5.Filter drier chocked 6. Compressor less pumping.
To rectify:
1 & 2.Clean air filter and evaporator. 3. Replace fan capacitor. 4.Check for gas leak and recharge. 5. Replace new filter drier, vacumize and gas charge.

Hello Sometimes there is a SCREEN in the liquid line just b4 the piston in the tube.You had a SEVERE burnout the filter driers are shot from doing there job even with the short run time.Also you could try pulling the piston out and blow out the cap tubes in the evap.Close the suction service valve and pressurize the pipe and let it blow out the piston holder ot help clear those tiny tubes.Use a OVERSIZE liquid drier this time,Get a 10 ton drier or better.

We just installed a new Goodman HVAC and the compressor lines freeze up. The technician that installed the unit cannot find the problem


Not to be critical, but not much of a technician if he cannot properly troubleshoot the issue.

Several issues can cause the freezing problems:

1. Refrigerant charge issue.
2. Improper equipment sizing.
3. Air flow issues.
4. Metering device issue.

First is under charge. But before making this determination several other things must be diagnosed and resolved.

Was the unit sized properly using a heat load calculation? You may not know what this means but a reputable, knowledgable contractor does. If the unit was oversized, it can cause the unit to freeze. If the indoor fan & motor were undersized. it may not be moving enough air across the coil and this will cause the coil & suction line to freeze.

Air flow issues, such as obstructions in your ducting or across your evaporator coil will cause the coil to freeze, thusly your suction line will freeze as well. Is the filter and evaporator coil clean? Are there any obstructions in the air passages (duct)? Is the duct work sized properly. Improper sizing of the duct work may choke down the required return air flow, and cause the coil to freeze.

The last issue could be a problem with the metering device. If it is an adjustable thermostatic metering device, was it setup to maintain a 12 degree suction superheat? If it is a fixed metering device, such as a cap tube device or bullet (orifice) device, it mat have a restriction (ususally a piece of solder or flakes from the soldering process clogging up the inlet screen). To easily check this, thaw the system out, start it back up when thawed and look for frosting or ice accumulation at the metering device outlet side. I fit does this rather quickly, then the system must have the refrigerant recovered (or pumped down into the condenser) and the blockage removed.

If it is air related, this must be fixed prior to properly trying to charge a system. Unless the proper airflow has been established, charging the system, or checking charge cannot be properly performed.

System not cooling space it cooled once before?


Hi, could be compressor loosing efficiency, i think suction pressure is to high at 85, also it could be moisture in your system, did mechanic replaces filter drier on high side of system , when he replaces evap. install filter drier on liquid line, if there isn't one, also check compressor valve, you can do that by cutting or desoldering the high side from compressor, connect charging port to compressor, conect your gauge charging port, start compressor, pump up to between 150- 200 psi shut off gauge, and leave for about 1 hr. then check pressure, if pressure decreases, then your compressor valve are leaking, if it maintain same pressure, then compressor valve is o/k. you can do same on suction side, this time in vacuum, if it holds vacuum pressure, then valve is o. k, RLA(LRA) lock rotor amps, is amount of amps compressor used to start, but will drop once compressor is running, 11.6 when operating is o/k, does your evap. compatible with condensing unit?, is it right size. check also that you're using right type of freon, check condensing unit & evap labels for right type of freon, make sure they can handle same type of freon. but check compressor valve carefully, i think your comperssor could be loosing it efficiency, compressor could be your problem. good luck.good luck

Have goodman unit, ac unit running 55 suction, 210 high side. cleaned condenser coils and charge to 10 degrees supercool. suction at 65, discharge 245, why did my discharge go so high


You should have liquid line filter/dryer that maybe restricted or there is a restriction in the orfice inside the evap coil normal operating pressures are 68/ 180

Extremely high head and suction pressures


disconnect the blower and turn on the ac.see if the coil frosts evenly.when you had the system open,you should have changed the liquid line drier.
