How to connect an air conditioner unit

How do you connect a RCSA-HM4821AU inside unit. I have already installed the outside unit, but have no instructions on how to connect the inside unit. I am unable to find any information on this type of unit online. I am trying to help a family in need of a new AC. The church bought the unit for them and I offered to help install it. Any help you can offer will be greatly appreciated.

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

I spoke with the Frigaire support line 706 374-4432. They said that the large piece of styrofoam, that extends from side to side and nearly top to bottom, is part of the unit. It should not be removed.

SOURCE: Goodman air conditioner will not turn on outside

When ever you hear a buzzing like you are hearing means one thing one of the fuses on the outside disconnect box is bad. Only getting 1/2 the power. Find the bad fuse and get the same size and will be good to go. ken

Does the orifice, which needs to be installed in the inside unit of an a/c for a house, come with the outside condenser? I had an a/c system installed and an orifice was never installed. the original...


The orifice is the metering device inside the evaporator coil and comes installed from the factory in the coil itself. Some condensers do come with orifices taped to the side of the unit, but they only do that to ensure you have the right size orifice. Sometimes you will have a 3 ton evaporator and a 2.5 ton condenser. In this case you want to change the orifice so that it meters the refrigerant correctly. But if you have a 3 ton condenser and a 3 ton coil, which is normal, you don't have to do anything. So to answer your question, your coil already came with a orifice inside and nothing needs to be done unless there are two different sized units as described above. Hope I didn't bore you too much and helped you with your question!

Had a Goodman heating unit installed in Oct. 2009. Recently tried to turn ac on .but no action. Installer returned and hooked up some wiring which got fan working but no cold air. The outside compressor...


It sounds like the outside condenser wires are still not hooked up correctly or there is a problem with the 24v electrical inside the unit. Describing what you have, I'm just banking on the connections. Now, if you have a heat pump system, there will be more wires and a little more difficult, but a normal split system will have two wires going from the furnace to the condenser. These two wires should be hooked to the Y(Yellow) terminal and the C(COM) terminal on the board inside the furnace. If it is a air handler unit, then it needs to be connected to the Blue and Yellow wires. The two outside condenser wires can be hooked up either way, it doesn't matter. I hope this is a simple fix for you and not something more. Good luck and I hope this helps.

How much would it cost to install the split unit outside since my trailer already has the inside hooked up?


Hi, I replace these condensers on a daily basis. Depending on the tonnage of the unit, lets say its a 2 ton unit, my cost is about 4 to $600.00 dollars wholesale. Then they are marked up. You are looking at around $1600.00 or more to install it total. If you know a contractor he can do it for 1/2 that. A heat-pump would be more. Just being honest with you.

Intertherm 13 SEER split air conditioner fans wont turn on?


OUTSIDE FAN OR INSIDE FAN OR BOTH. IF BOTH CHECK THERMOSTAT WIRE HOOK UP. IF YOU INSTALLED NEW TSTAT CHECK FOR JUMPER ON RH-RC TERMINALS ON TSTAT BACK PLATE. IF INSIDE FAN COMES ON WITH FAN IN ON SETTING AT FAN ON AUTO LEVER THAN PROBLEM IS AT OUTSIDE UNIT. CHECK FUSES IN BOX ON OUTSIDE WALL. SHUT OFF BREAKER FIRST.

Installed 4 brand new units, I have 233 volts going into the inside unit, nothing on the outside. Units will not even power on, no beeps, no fan, no nothing


Is there a disconnect next to the outside unit (required by code here in the lower 48). If so check to see if you have voltage to it, check the breaker going to the outside unit. Check on the inside unit circuit board for a blown fuse.

Not running outside


You may not be getting power to the contactor to the outside unit. Look for broken wires. Usually small in diameter. Dogs and critters love to chew on them.

Good Luck and hope this helps.

OUR AIR CONDITIONER DOES NOT WORK ANYMORE. THE FAN BLOWS INSIDE BUT THE OUTSIDE UNIT DOES NOT EVEN COME ON. BUT WHEN WE PUSH THE BUTTON THAT IS OUTSIDE IT COMES ON

Do you have any frost on the lines going to the outside unit. If the large line is frosted your evaporator (Cooling coil in the furnace) could be frozen up. Operating it with the fan in automatic with the cooling on will sometimes be the cause of this condition.

If there is not frost on the large line going to the outside unit and you are getting air circulation inside the house the problem could be a loss of refrigerant charge. Look at the joints where the pipes were soldered to the inside and outside units for signs of oil. If you find oil at any point it is the indication of a refrigerant leak.

Humidity


An air conditioner of this type always has standing water sitting in the base-tray of the machine as it's running. They're designed to work that way. However, if the unit leans slightly in toward the inside of your house, then the water in the tray can be deeper than it should and/or add extra humidity to the inside air. These units are designed to be installed so that they lean slightly to the _outside_ of the window or wall-hole where they are mounted. This way the standing water drains off to the ground outside and isn't so deep on the inside of the unit that it adds too much humidity to the inside air. Check the mounting of this unit to make sure it leans slightly toward the outside. Also verify that any notch or drain hole on the outside end of the unit, intended to guide draining water, is not clogged with debris (which could also cause the standing water in the unit to be at too high a level). Also verify that the "vent" is closed, if this unit is equipped with said vent opening. An open vent panel can allow humid outside air inside as the unit is running. Hope this helps! ;)
