Guest Hal Posted May 25, 2012 Report Share Posted May 25, 2012 There was some good info in Tim's thread, especially from Forcefed (I hope he shows up in this one too), but none of it specifically addressed my issue. My A/C is now running constantly too. I'm not 100% sure if the outside unit is continuing to run, or if it is just the inside fan. I'll check that tonight. The system (outside unit and lines I think) is new, installed mid-late last summer. I've replaced the thermostat and verified its operation with yet another unit. The thermostat can be switched to off and the A/C will continue to run. If the house reaches the correct temp, the snowflake icon will go off the thermostat and the A/C will run anyway. There is ice building up on the line at the outside unit, so that doesn't seem too good right now. I'm guessing this is an electrical issue, but I'm not familiar with HVAC wiring so I don't just want to start probing around. Does anyone know where I should start before I end up having to call someone? Quote Link to comment Share on other sites More sharing options...
KillJoy Posted May 25, 2012 Report Share Posted May 25, 2012 Have you cleaned the outside thing? Ours was packed with years of grass clippings, and it did something similar... KillJoy Quote Link to comment Share on other sites More sharing options...

KillJoy Yep, I got all the grass and ragweed off when I changed the filter. I have to clean it about once a month due to the placement.

acklac7 Posted May 25, 2012 Report Share Posted May 25, 2012 I'd venture a guess that your having problems with the main board (probably a relay) on the inside/outside unit $$$. If you can safely locate the main board try tapping each of the relays and see if the problem persists. Home HVAC is nothing but a headache, should have a thread of my own up here in a week or so.

Pedro1647545510 Posted May 25, 2012 Report Share Posted May 25, 2012 I had the same issue where mine would run constantly too and never shut up. It turned out to be the board as well. Can't remember how much it was to fix. Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted May 25, 2012 Report Share Posted May 25, 2012 is the compressor running too or just the fan? the fan should be on a temp switch I believe (for just the condenser, seperate from the t-stat inside). idk if the temp switch may be adjustable, if not it is possibly bad. disclaimer: I'm going off of how the company I work for builds them. the company I work builds them for industrial purposes and for server rooms and such. I know there are many differances from a home air conditioner. I'm just trying to give you something to look for and a possible starting point.

That's what is wrong with mine. The relays on the unit inside. Tapped them and the blower turned off. Quote Link to comment Share on other sites More sharing options...
Guest Hal Posted May 26, 2012 Report Share Posted May 26, 2012 Hal, want the # of my buddy that took care of mine? Yeah, that'd be good. Can you PM it to me when you get a sec? is the compressor running too or just the fan? the fan should be on a temp switch I believe (for just the condenser, seperate from the t-stat inside). idk if the temp switch may be adjustable, if not it is possibly bad. disclaimer: I'm going off of how the company I work for builds them. the company I work builds them for industrial purposes and for server rooms and such. I know there are many differances from a home air conditioner. I'm just trying to give you something to look for and a possible starting point. I believe it is just the fan, but I keep forgetting to verify. The guy who posted about a relay sounds like that might be going the right direction.

I have a name Hal, maybe we can be friends.:fa: P.S. don't forget to shut off the breaker feeding the AC when you go to check the relay.

wnaplay1647545503 Posted May 26, 2012 Report Share Posted May 26, 2012 In my experience typically a inside freeze is caused by clogged filter or duct and an outside freeze due to low refrigerant. Good luck. Quote Link to comment Share on other sites More sharing options...
