Hi,
Yes!! You need to blow out the drain... usually it is the trap that clogs...

Were do i get the manuel for model number ph3 12r03 is the model number were or how do I drain the water and can you send me a manual


Here is the link to the manual:

http://s3.amazonaws.com/szmanuals/b0348062b23e23cd40550b61e1dc5f43


Here are those particular instructions:


Compressor Indicator


The " " icon will light up on the control panel display when the compressor turns on. The " " icon will turn off when the compressor shuts off.

Emergency Condensate Holding Tank


When the room temperature is low and the indoor humidity is high, the air conditioner may not be able to evaporate some of the moisture fast enough. When this happens, the water will accumulate in an emergency condensate tank inside the unit. Once the emergency condensate tank is full, the unit will automatically shut off and the " " will appear on the control panel display. To empty the condensate tank, unscrew the screw plug at the bottom back of the unit. You will need a small pan, approximately 1" high to catch the water coming out of the condensate tank. Once the condensate tank is drained, the unit will begin working within a few minutes. The emergency condensate tank holds approximate
ly 1.5 Liters of water.

Another option is to purchase a small hose from a hardware store that can fit around the 5/8" drain plug on the back of the unit and drain the unit into a gravity drain or larger pan for continuous drainage.

To resume operation quickly, empty the water container according to the following steps:

1. Turn the unit off. Do not move the unit when the water container is full.

2. Place the drain pan accessory under the drainage port at the back of the unit.

3. Remove the screw plug from the drain hole. The condensate water will drain out automatically. When the drain pan is full, screw the screw plug back onto the drainage hole to stop the water flow. Empty the drain pan. Repeat until all the water is emptied.

Once the water container has been emptied, screw the plug back onto the drain hole. Do not allow the
water to drip continuously into the drain pan, as it might easily overflow.

No 24 v to contactor


The thermostat is the device that determines when the A/C unit starts up. It will require a 24v source (transformer most likely in the air handler) to provide power for the control. If the 24V is present, and the t-stat is calling for cooling, then there is probably a safety device preventing it from starting.

One such common safety device is a water level or "float" switch that detects water level in the pan under the air handler. These are most often found in homes that have the air handler in the attic space. Normally, these pans a dry or have a a few dropsof watrer in them. Condensate is created when warm, humid air is passed over a cold coil. It is collected and routed outside. If there is a problem getting the condensate down the drain pipe in the air handler, it will drip out of it onto the attic floor. This is why a shallow pan is installed under the air handler. The pan will collect the condensate and is piped outside and down to the ground. If the pipe has become clogged - preventing draining - the water would overflow the pan and ruin the ceiling in the space directly below. The float switch prevents the signal from the thermostat from turning on until the water has drained to a safe level.

Check the pan - if it is empty, the switch may have been distrubed and actuated - even though there is no water in the pan. Operated the switch to make sure it can move freely. There may be other safety devices inline like the float switch. You'll need to follow the circuit and find where it is being interrupted in order to make the repair / correction.

I hope this helps & good luck!

Excessive water dripping from Central A/C drian line


sounds like the overflow drain is picking up the water that means the main drain is clogged.you need to find the main drain pipe if lookin at the air handler in attic there should be 2 drains from unit one higher than other follow it and blow out drain they put the other overflow drain out the eve so if it stars leaking someone notices it and it doesnt damage cieling but it sound like it needs imediate attention befor it does go to the overflow pan and damage your cieling. i hope this helps and good luck

No cool air comes out of our unit even though it's running. System is about 2 years old-a little less. Filter regularly changed. The pan underneath is also full of water.


are the unit is upflow (on the closed) or horizontal (most like it on the attic)
if is horizontal and the drain pan is full seems the main drain is clogged can you blow air thru drain?  make sure you dont have a flow swith on the drain pan that prevent the condenser to come on

Little Giant Condensate pump runs for 1 sec when res not full


Is there a check valve in the pumps discharge fitting? If there is it may be stuck open or broken allowing some of the water to return to the reservoir once the pump shuts off which then may lead to the brief cycle between full cycles.

If there is not one, install one to keep any water from backing back into the reservoir and that should stop the short runs.

AC unit seems to be working normally but not cooling house


If you are referring to the secondary pan there could be a problem with your drain line.i would find the drain at the exterior of your home and **** it out with a wet vac..most A.H.Us have float switches or moisture sensors.They will shut down the unit if the drain clogs.

Pan missing when RUUD unit was installed causing problems with AC


I think your talking about an emergency drain pan. Is condensation building up on the outside of the unit? If it is, it means that the unit is not draining properly and the is too much water sitting in the main condensate pan. If you don't have the emergency pan, then the condensate drips from the unit onto the ceiling in your attic. I'm assuming a lot of things but this is what I think you are asking. You will have to find an ac supply company that will sell you an emergency pan and then it must be piped to the outside of the home or it can be plugged but with the use of a float switch. This switch will shut the unit off if the main condensate drain becomes clogged. You should have a professional come and wire a float switch unless you are knowledgeable about a/c equipment. I hope this answers your question.

My air cond is leaking water inside but works perfectly


If the unit is newer, there is a PVC male adapter that screws into the condensate pan. Typically they don't come loose unless it has been stepped on acidentally (attic install). The main condensate drain sounds like it is clogged. You can use compressed air to blow it out or try and run a small snake through it.
