Question about Air Conditioners

RE: Carrier Unit Central

I have an outside unit, Central Air, and I did stick a paper clip in the button on the unit outside that jumps the unit. So, it stay "ON". By doing this, I was able to learn that no air was coming out of the vents. I turned off the A/C and just the fan was suppose to be "ON", but it did not work. I looked inside of the unit outside and cleaned the dirt and other items from inside the unit. The unit is off now. I did notice the pipe that is inside the unit and it had frost /ice on it. I was up at 3 am trying to fix this problem. My wife made me do it! If, you are married, you understand. If, you are not married, "DON'T DO IT!" :-)

So, what can I do?

    I had a Pro come out and he basically told me what you told me. The system is about 10 to 15 yrs. old and a new system would save me or run 30% less to operate than this system. I could put that seal freon in that I used for my van. But, I decided to get a new system because of the age of my system.

    Thanks!
    OH . . . sorry to read that your wife is worst than mine! But, happy for me! :-)

LOL I understand the situation, bet my wife is worse than yours on this kind of things.
Regarding the unit that does not stay on there are two possibilities:
1 ) Unit switch is broken, in this case paper clip wont cause any damage, and the unit will just stay on.
2) There is a serious problem with the unit and the internal switch does not let unit to turn on, this is probably your case, if you force the unit to start with the paper clip it won't work because the safety switch keeps trying to turn it off, and with a reason.
I think there is a problem with the unit that does not turn on, If there is ice on coils then usually the AC is low on freon or the face of the coil has dirt on it and the air cant get out the one vent.
Only simple thing you can do is letting it off until it defrost then try just the fan see if you get air from vent if you do it is definitively low on freon. If fan does not start can still be in need of recharging freon, but can also be a problem with the fan motor.
A possibility is that your system was low on freon and when you set lower temperature settings for summer it went under pressure, froze and the machine went into error mode, if you cannot fix it in a simple way you will probably to call service to recharge freon and to inspect the machine.
If you decide to call service you can use the phone number printed on last pages of the owner manual.

I HAVE A CARRIER CENTRAL AIR, THE OUTSIDE FAN IS BLOWING INWARD AND WON'T SHUT OFF WHEN THE FURNACE SHUTS OFF AFTER TEMP IS REACHED


Check the t-stat to make sure that the "fan" switch is st to auto. If not the fan is in the "on" position and is always on. Otherwise, It sounds like your "Central Air" is a packaged unit(Furnace and air all one unit outside the home) and the fan relay inside the unit is stuck. This need to be replaced. It is the rectangular unit with the leads from the fan motor attached to it.

RE: Carrier Unit Central


Try first cutting system power for a couple of minutes, even from main. With some luck it can be enough to reset the system, as it looks like a problem with the control board. The control board has also a coin battery and a reset bridge on it , but to access them you need to take apart control unit. Try fist turning off main power switch for 5 minutes or so.
