Hi my name is Ricky
If you look at how it is wired does it have the jumper between RC and RH?

Ok so your air handler is not supplying power to the Nest. Is your unit in attic or closet?
Ask Your Own HVAC Question
Customer reply replied 3 months ago
it's in a closet upstairs, I am able to access it if that would be helpful.
can you tell if it has a float switch by drain?
Ask Your Own HVAC Question
or maybe under unit
Ask Your Own HVAC Question

Which end? The one by the AC filled w water? Or outside?
Customer reply replied 3 months ago
Okay, blow upward?
Customer reply replied 3 months ago
Should I go out and get a cheap shopvac?
Customer reply replied 3 months ago
Or worth trying?
you can try blowing from outside to see if you can break it loose. If it is to stopped up you may have to get shop vac

Customer reply replied 3 months ago
K how will I know if I got it loosened?
you will feel it blow through and a lot of water will pour out
Ask Your Own HVAC Question
Customer reply replied 3 months ago
As hard as I think I can.
May have to get shop vac to try and suck it out.

Are you 100% sure that's the cause of the error? And 2nd, what causes this to happens
Customer reply replied 3 months ago
My father-in-law has a shop vac I can borrow. How do I do it to fix it?
Customer reply replied 3 months ago
I'm running over to his house right now to get it.
It is just gunk that stops up your drain. It grows in the line because it always has water and no sunlight. In the future you can pour a little bleach down that plug the is in your other drain line to prevent it. Yes I am sure it will fix it. The line with float switch in it should not have any water in it.
Ask Your Own HVAC Question
Customer reply replied 3 months ago
basically the system shuts it off because he doesn't want electrocution to happen, is that right?
Just put shop vac hose over drain pipe, shove a rag to plug rest of hose around the pipe and turn it on.
Ask Your Own HVAC Question
No if you didnt have drain switch it would have kept running and flooded your house

Oooooooh
But you would still be cool lol
Ask Your Own HVAC Question
Customer reply replied 3 months ago
When I turn it on do I need to turn off breakers? And will it spray in the areas where the unit is?
Customer reply replied 3 months ago
Hahaha
No if you were blowing it out with high pressure it could blow it all over your closet but since your sucking it out you will be ok. Yes you can turn off breakers until you get your drain unstopped.

I set up the shop vac and I use duct tape to put it on the pipe. But it still hasn't loosened the clog yet
Customer reply replied 3 months ago
Any idea what else to do? The water is still in there.
Customer reply replied 3 months ago
Im still trying to do this
I'm so sorry I cut my phone off and went to bed. I thought you had to get shop vac this morning. Did you ever get it cleared out?
