Has started to drip water from the base of the unit - it is discharging from a small tube and is approx 11 years old

Sounds like condensation inside the door frame.

The internal seals are bad and it could be from bearing wear. Replace the unit. They are not that expensive.

I have a 20 year old one that drips after a while on a hot day. I put a small bowl to collect it. It could be old or the ac unit ins't tilted enough to go outside.

Hello and Welcome to FixYa!
Actually the leaking water is from the evaporator coil unit.... Under normal conditions,Self-defrost refrigerators usually dispose the water generated during the defrost cycle through a tube or channel that directs the water a pan (Known as Drip pan), commonly below the refrigerator unit....
The channel or tube is clogged and the water is leaking to the refrigerator unit, so you need to clear that blockage/contamination....Once the blockage is removed, the generated water will move through that channel/tube directly to the drip pan and there will no water on the floor in the refrigerator compartment. This is all you need to do....


Best of Luck,


Your token of appreciation in form of rating would be highly obliged,


Concerned.

The base of the unit is like a tray which collects all the condensation water. At the back of the unit (the part that normally sticks out the wall/window) there is a small tube where the water comes out. It is possible that this hole is blocked up with dust that the unit has drawn in and once it gets wet will block the water run off tube or pipe that can be fitted to it. If this tube is not cleared the tray will fill up and over flow everywhere. Hope this helps you.

This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

the collector base under the tubes just collects water and drips it through a hole into the water bucket. there must be a loose hose(if it has one) or the base collector or bucket has a crack, as they usually are plastic. also if the unit is sitting on a very uneven floor this will happen

hi! bill,
water drip it should be outsidethe house,beside there is a spout on the basin of your ac unit and hose to drip off outside the house,all you gonna do insert a piece of wood or metal on front side of basin, in between basin and the wall,just small piece object to elevate the basin to outside wall,the water will not stored in the basin.or make a spout, drill a hole 1/4" size at the corner at the backside of basin out side your house,be carefull not to drill condenser tube or the fan blade,insert a plastic hose 3/16" and weld it by glue gun.and end of hose put it an empty bottle so that the water drip will not scattered outside your house.regards and don't forget to rate me,thank's a lot

The tune up kit that I ordered arrived on Friday and I installed most of it on Friday night. While it is nice to have a new frame and the distribution panel and I think the price of the whole kit was fair considering it comes with the parts and 2 water panels, the fix was really simple.

The kit came with the water distribution tube with with a new blue orifice (Aprilaire #4232) already inserted. This orifice is in the end of the plastic tube at the solenoid end. When I removed the old water distribution tube, the old orifice was not really dark blue anymore but kind of a light blue and was deteriorating from 12 years of exposure to the chemicals in the water. What should have been a pin-hole size opening in the orifice was up to about 2mm or a little more so the orifice was letting way too much water through.

If anyone else has this leaking problem, and your orifice is several years old, I would check that first. It is a $2.75 part and may be the cause of the leak. The whole feed tube kit is only $8.75 and includes the feed tube, nozzle, orifice, ferule, compression nut, strainer so if you need to replace the orifice, I would order the whole feed tube kit for a little bit more.

Hope this helps,
Roger...

Most likely yours has a scroll compressor which are notorious for being quite loud on start they will start for years, just a liitle noisy. Is the water from the pvc drain or from the base of the outdoor unit??
