Both pipes haveto be insulated by a good insulators.{PUF}good insulation covering on the pipes so as to separate the in and the out pipe lines.It will increase efficency of the cooling.So keep them separately insulated.

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

Hi there I ve got a Samsung fridge model RL34SCSW1 my freezer is working fine it's just the fridge bit is not cooling?


Good day, please check at the back, at the bottom where the compressor is located for the pencil dryer(as in photo). Get a nice firm grip on it just be careful and feel the temp if it's cold or one side is hot and the other side cold the dryer is block. Otherwise feel the thickest pipe running into the compressor it should be cold if the fridge has been running for a while and the thin copper pipe existing the compressor should be hot. If the thin pipe is freezing up with a thick layer of ice and the dryer as some med-temp then there's a gas leak. If the thin copper pipe is very hot and the dryer has no temp then there's a blockage but if the thin copper pipe feels med-temp and the thick copper pipe more or less the same but a bit cooler the compressor is not pumping also feel if the compressor is running. If dryer as a warmth temp and the thin copper pipe is hot and the thick one very cold(when tipping your finger on your tongue and pressing it against the pipe your finger should stick a bit) if all checks out then it's the thermostat switching the compressor off at the rong temp.

Personal opinion in this case I believe it's a blocked dryer or gas leakage.

Pipes of outside unit do not get cold also no water dripping out of pipe


depending on how much moisture is in the space you may not see any water dripping out of the pipe, and only 1 of the copper lines should be getting cold underneath the insulation, chances are your compressor is not coming on or no refrigerant is going through the lines.
changing temperature does nothing for a system so as long as it says on, the actual temperature stting makes no difference, the system does work better or harder the further the setting is.
I would check that the fan is on and if the compressor is running they have a very distinct humming noise when they run.

"wiring for audio jack on a belkin fm transmitter model f8z439 the wires are purple yellow and green insulated with a bare copper strand surrounding the..."

Bare copper - ground
Yellow - right channel
Green - left channel
Purple - antenna I think.

I downloaded mp3 files from here: http://www.audiocheck.net/audiotests_stereo.php to test a bunch of combinations.

I found that any combination of purple and yellow gave me a correct right channel. Any combination of green and purple gave me a correct left channel.

The aha moment came when i attached the purple to the ground portion of the stereo plug along with the bare copper.

I have a trane xe 800 its blowing air but not cold air, i felt the copper/bronze tube running into the unit it is luke warm also no chill at all. where should i start checking to get my house cold again.


Hello, if the pipe with insulation is luke warm then either the unit is empty of refrigerant due to leak or the compressor is not running at all. Start by going tje the outdoor unitnand checking if the compressor is running, if it is then the unit has no refrigerant, if the compressor is not running then either a bad capaitor orbthe compressor itself might be bad.

My central air AC unit (Double wide home) always works for generally up to two hours, then it freezes up, by the copper pipes ice over, shutting them off and letting them thaw out, works to get it going...


You are absolutely right! The copper pipes should have insulation them. When they don't and they get cold in hot weather, they sweat and then freeze. Tubular Foam Insulation is what you need. Most home centers carry it. Once you cut and install it, be sure to wrap it in a good quality Duct Tape.

Hope this helped you. Good luck.

The air conditioner comes on but the motor fan dose not turn. I did rap new insulation around the copper pipe including the small pipe. I have just remove the small pipe from the insulation and now...


Hello, the smaller pipe is your liquid line, this line should never be insulated. The bigger pipe is your suction line and it should always be insulated to prevent condensation and so the refrigerant does not absorb too much heat going to the compressor. However, that should not affect the fan not coming on. It sounds like maybe a wire came loose somwhere going into the ac as you were wrapping the insulation.
