    The secondary or overflow drain is consistently draining. I know the main drain must be plugged. What is the best way to get this unstopped and how do you do it?

Hi Ken, Usually an ac repair man will take the front cover off the main AC coil. Inside,Below the you'll see the main drain pan. depending on how the drain is plumbed, the main drain should be to the left or right, corner. If you have a small compressor, you can blow out the line. If not, a electrical snake, or wire coat hanger will suffice. Be patient and go slow. Make sure you put a small hook on the end you'll put in the line. Move forward and backwards every two inches. Assuming you have two lines ( one for primary, one for secondary,) You should have a trap on the line. when you get to that portion take it slow. chances are your cloge is in this area of the line.

How do I get to the overflow tray to drain it? Where is it located?

The overflow tray should be on the indoor air handler, just below the connection of the white PVC drain line. It will require a 5/16 or so nut driver to remove the panel to get to the pan. It may be clogged in the pan where the drain connects or any part of the drain that is attached to it. Do you have any compressed air?

Air Conditioner (RUUD model: UBHC-14J06NFD) is leaking water from bottom. It is causing a major puddle in Air Intake area.

The condensate drain line/pan is clogged causing the condensation to overflow the pan.

The easy way to fix that is attatch a powerfull wet/dry shop vac to the end of the drain line and such out whatever is causiing the clog. Also take off the panel to the evaporator coil and clean out the pan with the shop vac.

To double check that the clog has been removed, pour a gallon or two of water into the pan and ensure that it is draining properly.

Janitrol air handler blowing out tepid air - Dry overflow pan

sounds like you have airflow issues, the static pressure is such that the siphon action of the trap cannot overcome the static pressure caused by the blower, have you put a new high efficiency filter in the system? It is very rare to have to install a trap in a central unit... if the compressor is operating, a quick check for charge is the suction line, (the large copper line outside) will generally be cold and wet, you should also feel hot air discharging from the unit outside.

Air handler will not run clogged up drain?

the air handler is in the attic or in a closet right? most likely the drain switch mentioned is in a pan located underneath the air handler, the switch is actuated when the condensation drain tube is clogged, ( when it cannot drain the water out of the pan), the float switch is actuated and the unit shuts off to prevent any more condensation, thus preventing overflow into your house/apt. the drain line can be sucked out by using a simple wet/dry vacuum of any kind from the end of the drain line ( usually a 3/4 inch PVC pipe located somewhere outside ).
