Outside unit is running but blower in attic is not working line in attic from outside unit is dripping water

With a non heat pump it is a simple 24 volt AC control circuit. In the attic there is a relay that is actuated via the fan control wire directly from the thermostat. On the thermostat there is an auto/man switch that controls the fan. Manual the fan runs all the time. Auto fan turns on and off with the outside compressor.

If the system is not calling for cool and the fan continues to run the fan relay is sticking. common problem. Sometimes after running for several days the relay will stop sticking if not, replace relay.

If the system is calling for cool and the compressor stops I would still expect the fan to run until thermostat tells the A/C to off. Some compressor units include a safety switch or high-pressure cut-out switch A blocked internal valve bad control board or external fan in outside unit defective no air flow in outside unit.
High pressure cut out not good,

Suggest turning temp max cool and observe. If acceptable cool and the compressor runs without interruption all is good, except for the blower in the attic. Safely check relay in attic blower circuit.

Hope this helps.

That happened to us. It was a broken pump, pump was up in attic. attached to our inside air-con unit. We had it fitted on an inside wall of the house, and so a pump must be installed to take away the condensed water to the outside of the house. Hindsight being 20/20 I would never buy one that needed a pump to get the condensed water out of the house. We would have put it an outside wall where the water goes straight outside, no pump needed. Our First pump lasted just over 2 years so warranty was expired. Cost us over NZ$500 to have new pump installed. Never again. Only attach your unit to an outside wall, even it looks prettier on the wall where it would need a pump. Bottom line:- Don't touch a pump. Pump was cheap but labor cost for serviceman astronomical! Bet of luck.

I assume it is dripping water when the AC is running. If you look at the attic unit, there should be a PVC pipe running from the unit - probably an insulated PVC pipe. This pipe probably goes across the attic to the edge of the house and drains outside. The drain pan may also have a drain pipe, but the one on the AC unit is the issue, and is probably plugged. Go outside and see if you can locate the AC drain pipe. See if the ground is wet below the pipe and if water is steadily dripping from the pipe (with AC running). If the pipe and ground are dry, the pipe is plugged. If you have a wet/dry vac, try connecting it to the drain pipe outside to see if you can **** the pluggage out. If you can get it clear, water should start dripping out of the pipe. This same thing happened at our house. I decided to cut the pipe in the attic, and add in a PVC isolation valve, tee, and water hose connection with plug, so I can valve out the AC unit from the pipe, remove hose connection plug, and hook up a water hose and flush the line to outside. Lowe's sells all of the PVC pipe fittings. The water pressure from the hose will always flush out the algae and crud to the outside of the house. I can also remove the plug and pour a cup of bleach down the drain pipe every couple of months to keep algae growth in check. I also cut out the trap (u-leg) from pipe in the attic and purchased a ready made trap a Lowes (the contractor who built our house had made a lousy homemade trap). I purchased a few PVC elbows and installed the trap on the drain pipe outside. By the way, our AC drain pipe comes out of our wall outside and drains near our outside unit. Our secondary drain pan drain pipe comes out outside from an eave on the side of the house. I don't know what you drain line looks like (it may have a port to add bleach, or some cleanout provisions, maybe not). If you choose to modify/improve it, then make a sketch of it, go to Lowe's and get the PVC parts you need + PVC pipe primer and cement. PVC cement dries fast. Remember, the pipe must flow downhill from you AC attic unit. You can use a regular wood saw to cut the pipe. I hope this helps you. You need to keep the drain line clear as algae will continue to grow in it. Pouring bleach in the line every month or two helps. You also need to check maybe once a month that the line is draining properly (check to see if dripping outside). You can get some serious water damage to your ceilings if the water backs up and overflows. I discovered that our drain line was plugged just in time as our drain pan drain line was also partially plugged and drain pan was about to overflow.

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

the drain coming off the unit is the one you need to clear, not the secondary pan. its usually clogged in the P trap which is usaully not far downstream from the outlet on the coil.

Sounds like your drain has sagged from the heat in the attic. It then backs up in the pan and sloshes around from the air moving. Get up there and see if that is the case, if so support the drain line so water runs freely to outside. This is an experienced guess. Good luck!

If the a-coil is on the suction side of the blower, the drain line needs to be trapped. take enough hose to make a circle below the drain fitting and then into the drain. The blower causes a suction up the drain line if it is not trapped and will not let the water go out the hose.

You could/can, but don't forget that (a) there is a good chance of heavy condesation, so size pan appropriately, or drain...and (b) The enclosed space where the drip pan is, is going to get quite warm. Hope this helps

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.

inside unit has fan control relay , either on control board or can be separate ,except for the 24 volt transformer and the t-stat the units operate separately concentrate totally on the inside unit this is where the problem lies
