Home A/C problem, need help

[Deers & Beers]

Did you pull any of the panels off the indoor unit? Some of them have switches if the panels are not on tight it will not run.

Nope, didn't do anything besides pour the bleach

Interesting. I looked at your top post and you said the ac was not running because of the water? Now that the drain is fixed it is still not running. If the fan nor the outside unit will run I would say you have a low voltage problem. Is this a float type switch? Try to push the float down and see if it clicks.

UPDATE:

Pouring half a bottle of bleach down the line seems to have cleared it up. There is no longer standing water under the cap. The pan is empty and the emergency line isn't dripping. I even took apart the line under the sink but it was completely clear.

REMAINING PROBLEM:

A/C won't turn on lol. The thermostat clicks then nothing. I was hoping it was because the sensor on the pan was turning it off since the water level was right about where it's at, but maybe not. Could having the line clogged for a few weeks have caused another problem? I checked the breaker and it's fine. Not even sure where to start now...

Is there water in the primary or Secondary pan still? there could be a switch in either or both. If you opened the unit make sure, that it is back together tight. There is a door switch on the unit that kills power. If the unit is together securely, there should be a small "window' viewing glass on the outside panel. Look in that window and see if you see any lights on. Usually red or green or both. if they are flashing, there should be a sticker on the outside of that same panel that shows what the flashing pattern means. see if that helps and report back please. We will get you fixed up.

Yes, try this too. I've seen many floats get stuck in the tripped position

Your main ac drain is stopped up. The line draining outside is your emergency drain it is telling you that you have a problem.

Outside line is secondary for sure. I'm guessing your units are in an attic of your 2nd story? Usually the main drain will be to the upstairs bathroom sink if you have this set up. Normally a blockage will be fairly close to the sink connection so look at it from that end.

Cycle power to the unit. Usually looks like a light switch or could be what looks like a circuit breaker on the front panel. Also, rather than a float switch in the emergency drain pan, they will sometimes install a "wet switch" which looks like a hockey puck lying in the bottom of the pan. It will have a pad on bottom. If it is wet, it will not reset. Dry it with paper towels. Chance are that after you cycle power to the air handler, it will reset and start running.

By the way, the best way I have found to clean out a drain line is with a shop vac. the bleach take too long for me. I want instantaneous results

Go to the sink in the restroom near the AC unit on the first floor. If you look at the drain from the sink you will see an extra line going into the wall and up to your AC unit. This is your primary drain. Might be a little different in your house but close. Pull the line apart and clean it out. Then go up to the AC unit and pour bleach water down the drain.

This is spot on. Just be warned....theres a lot of water backed up in this drain. when you take it apart, be prepared.

I pour bleach down mine when I change filters as a preventative maintenance

I agree. When I used to run service calls, that's all I would do. Some guys would blow the drain line out and we had one guy learn the very hard and expensive way that using nitrogen is not good. Cracked/blew-out the PVC line down in the wall. Water slowly ruined an interior wall in a million dollar house. After about 250k in repairs to the house, he was let go and Using nitrogen was outlawed by that company after that.

using bleach is great for preventative if done on a regular basis.

Agreed. A buddy of told me he buys some tablets at homedepot that works good
