Question about Air Conditioners

6 Answers

Not connected correctly

I had a wall mounted VENtop Air Con Unit installed 18 months ago and it blew more cold air out of the motor outside than the vent indoors. Installer came and said problem was it needed more gas. Problem persists. Installer no longer around. Cannot see a model number, stickers say VO5030035 and INT9000BTU2J, it's 220-240V and uses a seemingly universal remote (GZ-1002B-E3). Friend who completed air con installation course recently cannot find diagram for electrical connection & through trial & error managed to get it blowing cold air into room but outside motor fan did not function. Unless can get help with how to connect wires am stuck with a large white elephant! Please help.

    The gas appeared to be a ruse, the equipment was not correctly connected and now need installation diagram.

  • SadCanary Jun 15, 2008

    Friend seemed to think all major companies have some sort of connection diagram on unit, in order to make installation.

  • SadCanary Jun 15, 2008

    Do not believe to be Hyundai - any suggestion where to find product or model number? Only ID can find is "VENtop", which appears to be a Polish company.

  • SadCanary Jun 15, 2008

    Suggestions on correct procedure for connecting wires from outside Vent unit to internal fan?

  • SadCanary Jun 15, 2008

    Yes, that's the problem, the wiring diagram seems to be missing. Outside unit says EXT9000BTU CF C407 and Refrigerante R407C?830g but think that refers to type of gas or something. Anywhere else ID might be hidden - there's absolutely nothing obvious!
    Many thanks.

Connect up and use the control to go through the sequence of options you have.

Using suitable test equipment, take readings from the output connections you have.

One will turn compressor on off.
You should be able to find the motor connections quite easily, as the voltage will rise according to the setting.

As long as the compressor is wired to the correct on/off outputs it will cool.
There will be a temperature feedback loop in this to stay within limits - so will turn off when not required.

This should get the system working at least, but may need fine tuning to find the right connections so that the compresor turns on and off automatically.

Hope you found this useful.
Obviously a full wiring diagram would be very helpful if anyone can find it???

    Just to explain a bit better, One supply will be an on/off for the compressor. One supply will be variable - for the blower fan.



    The thermostat override will turn off the compressor supply when the temperature is cool enough, and come on when too warm.



    Hope some of this onfo will help you.

    From what you've said, The outside (refrigeration unit) is not working because the refrigerant gas has escaped through a leak.

    Therefore it has no gas to compress - and therefore won't refrigerate anything.



    Repair to refrigeration units is a specialist job, as the fault needs to be found, then repaired - often by high temperature brazing of conections. It then requires purging and refilling of refrigerant - then checking for leaks.



    I advise you find a different specialist refrigeration engineer to solve this problem, as it is not an easy self-fix.



    Hope this ends in a satisfactory manner.

As you that it is a gas problem, then the only thing you should do is better contact near service center because it seems to be big problem if you repair by own then it will cause serious problems .If warranty is there then go for it dont do trial and error method

Hi SadCanary

The first number you gave looks like a serial number, and the second a rating 9000btu is the heating/cooling rating. Can you find another model number anywhere? If you can, I will try to get a manual for you to assist with sorting it. Just remember that there are regulations about power switching and supply circuits for air conditioners that a qualified installer understands. They may only charge you a callout fee and say 1/2 hour labour to connect it for you. These guys don't need circuits and so on. Familiarity with these things means SAFETY.


I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

regards
robotek

My air-con is not as cold as before. I tried to lower the temperature, but when i try setting the temperature to 18 degrees, the remote just shows 18 degrees for like 5 seconds before going back to 31...


These is because you have not service your air-con for a long time. The cooling fins are clotted with dirt & dusts accumulated for a long period of time, and the water vapour caught between the cooling fins turn into ice when you set lower the temperture for the air-con. Moreover cool air from the blower/fan cannot pass thru', the cooling fins to regulate the cool air into your room.

You have to get the professionals to do a service on your air-con.

Hope it clarify your predicaments.

Hello, My condensing unit (LG-LMU245HV) and my wall unit (LG-LMN185HV) are brand new and were installed just one month ago. Everything has been running fine but now all of a sudden now the air coming...


Hi, when the copper lines at the condensing unit, the larger of the 2- start to form ice, you have a freon leak. The unit is new, so I would expect the leak to be at one of the welded/brazed joints. What will happen, is the indoor unit, the evaporator coil will start to ice over and block off all air flow through through the coil. I hate to tell you this, you will need to call the installer out to do a leak check on the unit. They will then need to pump it down, braze the leak with sil-phos, or silver solder and recharge the unit. This is the problem, I see this a lot on new units. Someone forgot to do a leak check on it. Being only a month old, it has to have a warranty on it, shouldn't cost you a dime, but this is the problem, indeed!! Please keep me updated on this and get them out there. It will never cool until they fix the leak and recharge it. Please don't forget to rate me on this, I know you will be kind. Keep me posted and you can contact me by my user name below. Thank you Zeke! You still have freon in the unit, just low enough to start the suction line outside to start to ice and loose your cooling.
Sincerely,

Water dripping from air con use


If the unit is mounted on an outside wall check the condensate drain that comes out with the line-set to the outdoor unit. If the pipping goes up into the attic than you have a small condensate pump that may have failed. The float in the pump may have stuck in the down position not allowing the pump to come on.

Have just installed a Fujitsu Asta 24lC air con heat pump problem


Hi Shannon,
I would pursue your fight with Fujitsu, normally their units are reliable:(
It could be a really simple problem or a really complex one ranging from many componenets. A air conditioner has many more components that people may think. Keep fighting to get the unit repaired will it is still under warranty, after that Fujitsu wont want to know you. It could also be a wiring and refrigerant fault. Call Fujitsu out again.
I take the time to answer your question, so please rate me.
Thankyou Mat

My Goodman a/c unit will not turn on ..


You have a short circuit in the outside system. Either a bad compressor,bad fan motor or possibly a bad capacitor. Visually examine the capacitor. If it is bulged out anywhere,replace it. Check for burned wires on the capacitor and all other connections.
Remove the compressors wires from the circuit and restart the unit. If the fan runs the problem is in the compressor. If the fan does not run,the problem is with the fan motor.

Panasonic air con unit is not blowing cold air out.


This unit is use in motels etc. Check the ouside coil ( conderser) from the inside (discharge fan ) for dirt. Most of these units are floor level . This can cause a unit to short cycle ( cold air is at the floor) .

Mitsubishi Air Conditioner FDKN Series leaks water after 30 mins


It could be one of two things -

1) The unit is not hanging level (assuming this is a wall mount, through the wall, or window unit), or
2) The condensate drain or trough to the drain is plugged/clogged/filled with trash.
