Without putting gauges on the system... It sounds more like you either are overcharged, have a restriction in your system or your metering device is not operating correctly.. hope this helps

Why is there no condensation?? My portable a/c Technitrend model TN09E has been running for several hous , and there is no condensation. And the temp controll is barely droping. Can you plase help o

The blower fan may be running, but the equipment isn't removing heat from the space. Apparently the compressor is not working. Don't confuse the noises of the blower motor with a running compressor. Check for cool air at the registers. No cool air = no condensation. Cool air, then check your plumbing from the pan under the indoor coil (evaporator). The drain line could be clogged.

One of the goodman condensing unit for my house starts good every thing works fine, but it runs OK for couple of hours and by then the refrigerant line connecting the unit condenses and it will not blow...

The refrigerant line is actually supposed to condensate, but if you mean "freeze up", thats a problem. The condensation occurs because the line temp is lower than the outside temp, kinda like a soda can outside. From what you described, Im pretty sure you are either over or under charged on refrigerant. The reason it will not come back on for a couple of hours is because the compressor is in "protection" mode and has to cool down before coming back on. When you are low or high on refrigerant, the compressor has to work harder which over heats and trips the internal overload switch. Have the unit charged properly and you shouldn't have a problem.

Hi Robert, I repair and install commercial refrigeration and may be of help to you. You need to determine the size of the evaporator coil so you can match up the condensing unit for it. I don't no the voltage that it is, but this makes no difference, just make sure the condensing unit is the same. The condensing unit comes as a package, compressor, defrost clock, everything you need. All you need to do is run your copper, suction, and discharge lines and electrical through the roof and tie in at the evaporator. Install your driers and site glass at roof on your liquid line going back to the compressor.Your new condensing unit will have your power lines out, marked for you to tie into. You will need to set a disconnect box at the condenser. I am not sure what this box has to run, evaporator fans and a thermostat. All other controls will be with condensing unit. Since you are setting this up simular to a walk-in box, if the box didn't come with a txv, ( Expansion valve) you will need the right one for the evaporator to match. A liquid line solenoid valve at the evaporator to start and pump down the unit when the stat is satisfied. It will be wired into the thermostat down below. When you go to the parts house take all of your model, serial, product numbers with you and cubic inches as well. They will fiqure out the size you will need and what you will need. Wiring is very easy doing what you are doing, but if you feel you need a diagram, ask them and they will come up with a drawing for you to work from. They are very helpful if you are getting this condensing unit from a refrigeration parts wholesale house. Thay will tell you exactly what you will need to split this box. I hope I haven't confused you. It is basically very easy, just take your time and you can do this. Best of luck,

I have side by side refrigerator model 106-52709-100. Light is on, I can hear fan running but no cool air in side. Actually, thers is no air coming in inside. What is the problem and how to resolve ?

Is the compressor motor running.If no check starter/overload relay.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

How to check stuff>

Is the evaporator fan in the freezer running.
Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

Reason for inverted suction line above the evaporator

To keep the freon from flowing back into the compressor, flooding the coil and washing the oil off the rings in the compressor.

Water/condensation is backing up in the bottom of the unit and overflowing into the house.

The drain in the condensate drip pan is clogged. Locate it and clean it out.

No cold air

The evaporator coils on the front of the air conditioner get very cold during normal operation of the air conditioner. As the warm moist air in the room comes in contact with the cold evaporator the moisture in the air condenses out of the air and attaches to the evaporator coil. As more and more moisture condenses the water begins to drip down into the base of the air conditioner where it is evaporated to the outside of the house.... so the problem might be in ur evaporator coil.. try replacing the coil if u are an expert or else with the help of technician try to fix it..
Is the thermostat knob turned to the proper setting? Is the compressor motor running? The compressor is a football-sized case with no apparent moving parts. It is located inside the air conditioner at the center. Is it humming or making any kind of continuous noise or causing the lights to dim? If it is making a continuous noise, and your air conditioner is still not cooling at all, there may be a serious problem with one or more of these areas:
These items are not user serviceable. You will need to contact a qualified appliance repair technician to repair these components.

If the compressor is not running but you do have power to the air conditioner there may be a problem in one or more of these areas:

Overload and/or relay
Thermostat (Open thermostat)
Burnt wiring
Bad selector switch

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......
