Condensation leak on downflow AC system

It sounds as though the ac has done this for a long time,may be since it were new.Does it cool good when it is on?Or does it take a long time for it to do the job?I am thinking,from day one the ac unit was charged,incorrectly,There is air in the system,and not the proper amount of freon.This would give a tech.a false reading if he where to attach ac gauges up to read pressures.It has happened before.The ac units are charged with a machine,and between freon and the machine it traps air,and pushes it in the system.The machine is set to a certain amount of freon to charge.When the machine senses that amount of freon has been injected into the unit,it shuts off.My advice would be to evacuate and recharge the system to spects,with manual gauges.This would assure the right amount of freon,and the tech.would be able to do this with his eyes closed,and know it is done right,ac men know there gauges,I know,for I am one myself.Let me know some feedback on this [email protected]

Air conditioner blower motor replacement from a four-speed to a three speed and reconnecting the four leads

Your blower runs on 240 volts. So 3 wires are speed and 1 is the neutral. Likely white is neutral/ L2 and then you have your three speeds. So you will still have 1 spare 1 for cool 1 for heat 1 for l2/neutral. Model number of motor and unit usually helps for proper diagnostic though.

Apu starts fine but no

Hi there, Would this be a preheat / comfort pro APU? If so I would start with removing the top cover on the APU. There will be a fuse holder with a 20 amp fuse on the back wall on the left side of the APU above the APU controller. Check and see if the fuse is blown. If it's not then the CCU board under the bunk/ bed isn't seeing power. Either 12v harness or the communication harness both from the APU controller to the CCU board are rubbed on the frame, or the CCU board isn't transferring power properly. The CCU board is under the bunk. There are 4 3/4 bolt's that hold the lid on. Start the APU and look at the board you should have green light's light up. these light's are called input light's. Then chose a function on the driver control panel as in heat, a/c, low or high fan and see if they come on. If the driver control pane are showing the function on look down at the CCU board and see if there are orange light's on. these light's would be your output light's. There's a lot of cause's for this problem if you need further help feel free to ask. Thank's

My carrier ac if i on the unit it will show green light 9 times blinking after off then 2 sec on green light again 9 times unit is not working

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If that dosn't work then you should contact a professional. AC Repair West Palm Beach
