Ruud UBHC17J11NFA: Condensate pan filling up - condensate pump works fine

There must be a hole in the condensate pan if it's not coming from over the top. Bleach only prevents mold and bacteria growth, not blockages. Check and clean the drainage tubing connected to the condensate pump

Hello, usually a clogged condensate line or cracked condensate pan will cause this. try using a wet/dry if you have one to unclog the drain by attaching the hose to the end of the condensate line, the line will be made of PVC pipe. if this does not help than the condensate pan under the evaporator coil is cracked and will have to be replaced. in some cases if your unit uses a condensate pump that could be the problem aswell if it;s clogged or not pumping.

Hello, most likely you have a clogged condensate line, in order to clean it you will need a wet/ dry vac and attach it to the outlet of the line and the suction pressure should dislodge the clog. Also, if the unit uses a condensate pump make sure it is working, if its not it can cause water to pour out onto the floor.

The source of your problem may be the drain pan that captures the condensation and then drains it into the condensate pump hose.

Yes you'll have to remove the side panel to access the pan. The pan drain may be clogged with lint and mold. It's not difficult to clean once you access it. If you see mold, you may want to place a teaspoon of bleach in the drain pan once it has been cleaned. Future condensation water will dilute it and move it around.

Check for some type of float switch in the condensate pan. It will shut down the unit to prevent more condensate but I am not sure if it would still allow the indoor fan to run.

If the condensate drain is clogged, water will stay in the condensate pan located below the evaporator.
As the water builds it most certinly will be picked up by the blower and travel through the duct work.

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.

Sounds like from your info you have a stopped up drain line. When you say tray I am not sure what you are going to empty. Does the unit empty into a condensate pump. If so sounds like you have a pump problem. If you have a small pan underneath the ac unit with a small float. If this is filling up. You have a stopped up drain. If you can blow out the drain from the inside good. If not the best way is to take a shop vac and **** from the outside drain line. BEST pulls everything out. Rus

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.

I think...yes. Stopping the machine before the water fills the secondary pan couldn't hurt, but don't take the secondary switch out. (Wire it in series with the primary switch.) Air conditioners get plugged up in places besides the primary drain pipe and the secondary switch wii catch anything the first one misses.
