Question about Heating & Cooling

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.

    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.

A/C Compressor wont kick on unless jumped in fuse box using a paper clip. Compressor does not kick on with relay in place. Freon levels are between 35-40psi on low and 190-200psi on high side.

Normal pressure with the engine-compressor off is outside air temp. So both gauges would read 70 or 80 or whatever.
When the system is running, normal is 30-50 low and 200-300 high.
One thing that comes to mind to test is the low pressure switch.

If you are using this inside your home with central air running do you have to vent it to an outside window?

Yes, it must be vented to the outside, even if you're using central AC, too. The reason being is if you don't vent it to the outside, the hot air and humidity that normally goes thru the duct and out the window, will stay in the house and your Central AC will have to run longer and harder to overcome this rise in heat and humidity. In addition, the room that the portable AC is in, will get extremely hot & humid.

Hope this helped you. Please let me know. Thanks.

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...

If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

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.

Blower fan keeps shutting on/off,

Your blower fan turning on and off shows your thermostat is working. I am willing to bet you have the fan in the automatic condition. Check for a sticking contactor at the outside unit.

How to reset air purifier

(from the manual) Turn off the unit. Look just below the last light on the "filter change indicater meter". You'll see a very small hole and the words "reset". Use a sharp object, such as the end of a paper clip (opened up) and stick the paper clip or sharp object into the hole. This is suppose to reset the unit. However, I have heard of cases when people of done what I just described but the indicator late still will not reside to green. I hope this helps you.
