Goodman Model CK60-1C with White Rogers mercury tube thermostat

The ac unit will freeze outside on the larger copper pipe running from the house to the unit (Low Pressure Side?). The fan motor in the attic will kick off but the outside unit continues to run. There is frost on the copper pipe I mentioned before. If I cut everything off for about a half hour, it will work normally for awhile but will eventually freeze up again. It actually seems worse on the cooler days than on hot days.

I had the freon pressure checked on the low side and it was 70. Apparently it isn't low on freon.

The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.

Sounds like an airflow issue.How is your filter?Blower wheel clean?Depending on the temp in the house,70 suction could be low(very unlikely)

Goodman ez-1425 ac copper pipe keeps freezing up

copper pipe freezing on the outside indicates that there is liquid evaporating in the space created by the suction of the compressor
the pipe normally will be insulated to stop atmospheric humidity condensing on the pipe
Suggest that you get in a technician to check gas pressures and ac operation

Have a Goodman AC unit (model: GSH130421AA) in my two story town home. The upstaris does not cool, however, downstairs does. The outside pipe(?) that leads into the AC unit was frozen; looked like a snow...

Hello, when the pipe freezes up it usually indicates a airflow problem or low refrigerant charge. Check the air filter, blower wheel for any dirt. Also, make sure the blower motor is running. If the airflow checks out good then the unit is low on refrigerant and must be recharged by a hvac technician.

Thermostat wires running from house to outside Kenmore AC unit were chewed by dog. Got replacement wire. Took panel off. There were three encased wires running into AC unit that were chewed. Only see...

If you have a central air conditioner, or a split system, where the indoor unit is attached to the furnace and a outdoor unit is located outside of the home. 2 copper lines will be connected to it, a larger and a smaller one. If it is a air conditioner and not a heat pump, the A/C usually uses 2 wires, that are connected. Allot of times a installer will use a 3 wire thermostat wire, to run to the outdoor unit, if this is the case, the third wire will be folded back out of the way.
The color of the wire is usually picked by the installer, I myself usually use white and red and fold the green out of the way. If you only had 2 wires hooked to it to start with, it really would not make a differace which one you hook up to either one of the yellow wires.
All you are doing it having one wire coming in and one wire leaving,,,, just creating a complete circuit, just don't connect the two yellow wires together.
Example: If you have 2 yellow wires on the A/C unit and 2 wires coming from the house "example a red and a white" hook the white to "One yellow wire" and the red wire to "the other yellow wire".
You are just creating a complete circuit, when the thermostat calls for cooling, it creates a magnetic pull and closes the contact points, in the air conditioner, outside, this allows the 220 volt to flow to the compressor,,, and ahhhh cooling!
I hope I have not confused you, I am just starting to help on this site and still trying to make things understandable.
Wish you the best,

Not cooling house it stay on unless you turn the thermostat to 88 degrees

if the the outdoor unit is running and the larger of the two copper lines going into the unit from the house is not cold you are probably low on freon. if the line is iced up then you need to shut if off for 8 hrs and try again, make sure the filter is clean recheck the large copper tube again if its not cold your probably low on freon. if its not running at all outside check your breakers. there are a number of diffrent things that may be wrong and you probaly need a service company to look at it.

Goodman CK60-1C model central AC unit blwing hot air

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

Ac problems

Hello from KOOLBREEZES, this is a simle problem and easy to fix. You have 2-lines going to / from your outside unit. a SMALL COPPER -line and a LARGE COPPER line with insulations. The fat line is suppose to have moisture on it wheres it,s not insulated which tells you you have enough refrigerant gas comming back to he compressor but if its dry you,re low on freon and need a charge or the outside condenser is dirty and not getting rid of enough heat!
