Question about Ruud UAKA030 Air Conditioner

1 Answer

Water dripping (almost running) out of the left corner of air handling unit. Help???

I have a Ruud Air conditioner/gas heater with the furnice and air handler located inside in my utility room with the air handler sitting on top of the furnace. Last night I noticed that it was not getting quite as cool as it should be getting inside and the air conditioner kept running. I checked the filter and it was black & soaking wet! I just changed the filter about 4-5 weeks ago. I changed the filter again. This morning when I got up I went to check the filter to make sure everything was lookin ok, only to find water all around the unit on the floor. After watching the unit a while I discovered that I have water dripping (almost running) out of the front left hand side of the unit. I went outside to the condensation pipe and found that the condensation out-put was not as much as it usually is. The pipe appeared to be clogged with brown and slimmy gunk. I took a clothes hanger and cleaned the little "L" pipe out the best I could, which is only about 7-8" long before the pipe takes a 90 degree turn through the wall to the unit. The tempatures here for the past couple of days has been over 100 degrees and the same is predicted for today (current time is 1:03am). The water dripping out of the unit seems to getting worse. I have a dog and 2 cats, not to mention myself, to try and keep cool, but I have been forced turn the unit off until the dog starts panting. I have contacted several HVAC companies, however, with the high temps they are currently booked for a few weeks. A few minutes ago I felt the air handling unit and it feels cold to the touch. Any help, information, and/or suggestions as to what I can do on my own until I can get a professional here to take a look would be greatly appreciated. What would be causing this problem? Other than the water issue the unit seems to be working fine as far as cooling the house. Thanks. Vanessa

You're correct in checking the drain pipe, because it's become blocked. The only trouble is, you're trying to clear the wrong end. The condensate water is spilling out of the air handler because that's where the pipe has a clog. These pipes usually have un-glued joints next to the air handler, for times such as this. If you can't pull them apart, you may have to cut the pipes and reconnect tham with fittings from the hardware store. (which is a normal procedure.) I usually use a wet/dry shop vac when repairing this problem, sucking out the clog & the water, then blowing out the line to where it drains outside. I've also used the clothes hanger technique to drag crud out of the air handler fitting. Hope this is helpful. ;)

The fan on the Ruud furnice unit runs all the time but the Ruud ac unit is not kicking on . I know nothing about any of this but would like some Ideas what I might check. I went outside and could not find...

Some Ruuds have a red rubber cap reset button on the bottom of the unit or inside. Usually the fan quits and trips the switch. Or look at the metal run cap with 3 leads on it, if it looks bulged(concave on top) and not flat and sunk in, replace that and ur good to go. Let me know. Please pull the power disconnect if you attack the cap, and write down what leads come off which terminals. [email protected]

MY ruud silhouette gas furnice unit comes on but burners don"t.can't see pilot light.the unit has electic ignitor

You either have a spark ingitor or you have a glow coil ignitor. The glow coil ignitor is located on the left hand side of the burners. It is a very fragile part.

If you have a mirror or have good eyes, look to see if
it has a crack in it.

My ruud silhouette ii gas furnace is blowing regular air. i know nothing about a/c? is it freon?

Check outside unit to see if it is working. If fan is blowing outside put your hand over unit to see if air is warm. If outside unit is running and air is cool. Low on gas or compressor not running. You need to call a service tech to check it out. Also check the brreaker on outside unit. Russ

Too much water condensation

Check your condensate drain. It could be plugged. Or perhaps you have a crack in the drain pan.

Is there a connection between a warm floor and a water heater?

Is the floor warm just in certain spots or all over. If just in a certain spot you may have a hot water line leaking in floor.

Unit continue to run nonstop

possibly two or more problems. drain may be plugged and therefore no water dripping from it. attach a good wet dry shop vac and **** it out. listen for good suction at in door coil when vac is attached outside . feel large insulated line outside . it should be ice cold to touch but not frozen . if it is kinda cool then your low on gas. if its froze you are low on gas or dirty filter ,coil , or blower wheel. .you can measure temp drop between return air in and supply air out at the in door blower . it is usually 18 to 20 dgrees , in at 80, out at 60 so to speak. greater than 2o and you have a restriction like dirty or filter or froze up. less than 15 you are low on gas or inefficient compressor. be sure your fan is in the auto mode , not the on mode or indoor fan will run 24-7.
