Question about Ruud Heating & Cooling
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.

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
