I bought the amcorair one of the inside units is not working right. IT IS SET ON 72 degrees and it does not cut on even at 66 degrees.
Hi, from what you are saying, it sounds as though you have a control/thermostat problem. You say it doesn't work right, so I am assuming it does work, but just does not come on when the stat calls for heat. Make sure you have 24 volts to the stat. Turn the fan to the on position to see if it comes on. If so, you have power. If the heat is not coming on at 66 degrees, and you have it set to call for heat below 72, you do have a problem with this stat. The room sensor is mounted in the circuitry of the subbase, or second section of the thermostat. There is nothing you can do to repair this stat, your only option is to replace it. If you have both heating and air, you will need a stat for that. If you have gas heat get a regular central heat and cooling stat, 24 volts. If you have a heat-pump, you will need a heat pump stat. The best thing to do, is shut off the power to the indoor unit. Remove the first section of the stat, it should just unsnap. You may need to pull some to get it off. Then you will see the subbase with the wire terminals. If you have gas heat, it will be marked something like this. RH to RC with a red wire connecting the two. You will have a smaller red wire coming in from the indoor unit which can go to either one. You will see Y yellow for cool, W white for heat, G green for fan. If its a heat pump stat, you will have many more terminals such as o/b, may have E and C, w-1, w-2. Draw you a diagram of the wiring and the terminals they go to. Now, remove the subbase. It will be held to the wall with a couple of screws. Take it with you, and go to Home Depot, Lowe's Hardware, O.S.H. to get a stat. Try and find the same one, but it will not matter as long as you have the same terminals. Many stats will work on many units. Install it in the reverse order. This drawing is very important for you. This will indeed solve your problem, and is very simple to change out. If you have any questions when doing this, please contact me, as I will check in on you. It may take time for me to respond if I am on another call. Please don't forget to rate me on this, I know you will be kind! :))
A/C, & Heating Contractor PS, Don't loose the manual for your new stat!! Put it in a safe place, this is very, very important.
