Codenser problem from compressor liquid line to beginnig of the a/c condenser line it is hot pas to condenser line it is warm

no
the gas from the compressor is pumped to the condenser to be turned back to liquid to go to the TX valve to be released and be turned back to gas
if the condenser is blocked , the gas is turned into liquid by the high pressure generated by the compressor in that line
from the condenser on there will be low pressure as the compressor forms a vacuum back to the condenser
the low side is the hose from the evaporator to the compressor
the high side id the hose from the compressor to the condenser

the condenser will be hot if the compressor is working as that is where hot compressed gas is cooled back to a liquid
could it be that the thermostat setting has been reached and the compressor has stopped until the fridge warms up enough to turn it back on
when in doubt call a technician before the food spoils

The condensation will be mostly forming on the suction line to the compressor . It is the moisture in the air forming water droplets when the air hits the cooler pipe. The refrigerant boils off inside the line because of the low pressure cause by the sucking action of the compressor and this boiling off reduces the temperature of the line and so the condensation forms . It will be the larger of the 2 pipes and if this condensation is causing concern then there is a form tube that you can get from the rubbers shops that you can wrap around the line and this insulates the line and so the condensation will not form. When the system is working properly you will notice that the smaller line will be quite hot as the compressor compresses the refrigerant back into a liquid so that at the TX valve in the evaporator(inside the car) releases the liquid into the vacuum created by the compressor sucking on that line. The heat in the car helps boil off the liquid to gas and in doing so removes the heat from inside the car . As it is doing this there is condensation forming on the evaporator fins that drains off out a tube to outside under the car ,hence the pool of water on the road as you drive off.

That piston is the metering device. On the liquid line, before the metering device it is always warm (this is sub cooled, high pressure liquid), but should flash to low pressure, lower temperature vapor once it passes through the metering device. The suction and liquid line never connect together.The liquid line brings liquid from the condenser to the evaporator. The suction line brings super heated vapor from the evaporator to the compressor. Since the unit does run, I'd have to put a gauge on it,but if I had to guess, I'd guess you have high head pressure. Check for dirt or debris on the condenser, check for proper clearance of the condensing unit and check for operation and directional rotation of the condenser fan. This could also be the result of an over charge.

Hi,

Unit is low on freon......

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Hi!!

Don't worry about the line, it is supposed to be the way it is. If you are talking about the condenser coil, located on the back bottom part of the unit, with a small fan in front of it, yes, it is supposed to be hot.

The condenser job is to disipate the heat absorbed by the evaporator (the coil inside the freezer). Make sure the condenser is clean and condenser fan is working, also, make sure there is air circulating thru the back of the unit to help cooling the condenser.

The noises you hear, are probably the defrost coil melting the ice on the evaporator, this function is on a timer and happens 3 or 4 times a day.

Good Luck!!

The fans are inportant but the regular raditior fan will do it and the road speed of the car will blow enough air though the codenser to make it cool if it's going to. Does the compressor turn on? if it does do the lines hooked to it get hot?( the small one) and the big one get cold? The condenser should get hot, Hot enough to burn you and the freon level may be wrong and or the compressor isn't pumping. ( brocken inside)

why not then when its down to zero shut the unit off and open the lid and free freezing...no electricity required....remember pop machines sit out in all types of weather

The small copper line should not be really hot its supposed to be carrying liquid refrigerant which has already had the heat "pressed" out of it by the compressor and carried of by the air flowing over the condenser coil. This could indicate a few things; that your unit is overcharged, you have a mismatched evaporator coil and condenser, an ineffective condenser fan motor or a clogged condenser coil and as a result your compressor is shutting of due to an overload condition from the building heat and back pressure between the compressor outlet and the evaporator inlet.

First make sure your condenser is clean and that adequate air is flowing over the fins of the condenser coil. Then be sure your equipment is a matched system. A indication that your condenser fan motor is not at speed is slow starting a humming sound and excessive heat. In my experience this complaint is generally the result of a bad condenser fan motor that over heats and shuts of after a short period and the build up of heat in the liquid refrigerant line of course trips the compressor overload circuit- which by the way usually takes hours to reset. I hope you've already resolved this, but in case you haven't......

A couple of consequences to a dirty condenser. First the compressor could have blown a valve. Second the cap tube and/or liquid line drier could have clogged - If the unit has R-134A this is more common than not.
Of course there is also the possiblity that the dirty condenser had little to do with the original service call and that the unit is low on refrigerant or has a faulty thermostat.
