Question about Carrier 38CKC042 Air Conditioner

1 Answer

My A/C outside will not run, inside a fan is blowing air (a little cooler than the 82 degrees it is in here, but not cold). Unlike all the other posts I've read, my unit outside is not making any noise. I makes a click when I turn it on at the termostat 1 time and then nothing. All this started yesterday sometime, after the remains of TS Fay left us. Help. I tried the breaker thing and resetting the 240v box thing outside at the unit. Help.

    My unit is not Carrier...don't know how or why that is in my post. I have GrandAire.

    Also, what is the "panel". Is this anything i can see without taking anything apart. I don't want to risk my warranty. I just want to be on top of this and not get taken by the company. He and the builder already hate eachother.

    Thanks for any help you can provide. Also, did your transformer need to be replaced? Did you do it? What was the cost if you did?

I am not an a/c expert but mine did this one time and it was the transformer I think it is called pull the panel off and look for wires burnt at connections also. BE sure you cut power off before doing this

I have a Lennex heat pump unit which was installed in 2008. Our area (Savannah, GA) has experienced some abnormal cold temps lately. Yesterday, I noticed the outside of the unit had frost on the unit. ...


Heat pumps are the same as an A/C unit only it works in reverse. Instead of blowing cold air inside and hot air outside it blows hot air inside and cold air outside. The heat being blown inside is extracted form the cold air outside. Its called Latent heat Latin for hidden. Believe it or not even though its 20 degrees outside there is still heat in the air. Example if you want to drop the temperature of a freezer from 20 to 10 degrees you have to remove heat .I know your getting unusal weather and that is the problem. Heat pumps can only work no lower then around 20 degrees outside.Heat pumps are never used above the freeze line. With your unusal temperatures thats basically where you are now. Ride it out. When your temps rise a little your be fine. Im in Chicago.

REPLACED BOTH ELEMENTS GOT HOT WATER FOR 1 SHOW THEN IT GOT COOLER AND COOLER AND NOW ITS COLD ONLY?


Find a reputable HVAC contractor to do a room by room analysis with heat and cooling loads calculated and units sized and duct requirements and compare to what you have.

The air not being cold is not necessarily an indicator of anything malfunctioning. High efficiency units for instance don't produce cold air.

Since you have had someone look at it, the duct work may be collapsed which restricts air flow or uninsulated which warms up the supply air. Either one is a possibility. Any Cox Cable guys been stompin' around your attic lately? Wouldn't be the first time.

Usually, when the air coming out of the vents is not cold enuf it's because your freon level is low. Probably leaking, but they can usually recharge the freon and it will work for a while. Try another repair company and see if they can recheck the freon level.

We have a high efficiency unit and it produces cold air, so I don't know what previous poster is referring to. Air conditioners are supposed to blow cold air.

Sorry, to tell ya but it is normal if the outdoor temperatures are much below 45 degrees. Below 45 degrees there is little heat outdoors for the heat pump to grab to heat the home so it will run 24/7 and blow cool or cold air. Below 45 the temp of the air coming out the vent will decline and you will get no heat from the heat pump itself as you near freezing.

Your emergency heat or auxiliary heat is electric strip heat. But it only kicks in during normal operation if the temp in the house drops 3 degrees below the setting. (some tstats if can be 5 deg.) Otherwise the heat pump will blow cool or cold air the rest of the time if it is too cold out.

To prevent it from running all the time and blowing cold it is recommended if the temp outside is falling below 45 degrees you should just switch to the emergency heat setting, which shuts the pump outdoors off, and just heat with the electric.

But if there is no heat outside the heat pumps will blow cold. They are the cheapest and most efficient forms of heat but only as long as the outdoor temp is above that 45 deg..

I'm guessing that if you haven't experienced this you live in some place with moderate winter temperatures like in Northern Florida and rarely get very cold winter temps like the freezing you have seen there recently.

It will likely blow much warmer when the outdoor temp rises.

Cant keep cool


You need to check that tour filters are new. Then check that air is coming from the vents and is at least 15 degrees cooler than room temp. If no air coil is frozen, or blower motor and run cap are not working. If frozen than turn system to off and fan switch is on until you feel air through vents.
You'll need to make sure the outside unit is runing and the larger copper line is cold like a can soda. If it's cold but is freezing up, it needs to have a charge added. If its running but not cold and the fan is not running or the compressor isn't running it could have a blown capacitor. If its not running at all check. the circuit breakers and reset them. And a good idea to keep the outside unit washed with water,and that it is clear of weeds and stuff.

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

Air conditioner/furnace was working for the past few months. Came home today at it is at 81 degrees, although my set temperature was set at 72 degrees. Temperature is rising to 83 degrees and I can't...


Check outside breakers. Open up outside panel and see if contactor is pulled in. If so you have a voltage problem or a bad capacitor. Sometimes a wire burns off. So look for this. If you have a float switch on the inside unit it may be tripped. Stopped up drain. Russ

The thermostat is set at 73... the air conditioner is running and cold air is blowing but the house is currently 82 degrees. I've checked the unit outside and there is no icing. I don't know what to do.

Air Con Unit Not cooling the room


Alright, I'm obviously not there, but you could be low on refrigerant/Freon, and what is more likely, your AC is suffering from some sort of obstruction or debris, as noted in this handy diagnostic article that explains how it could cause your AC not to blow as cold air as you would like:

Hope this helps.

P.S. As to the loss of your operating manual, try to see if you can get another one directly from the manufacturer by contacting it.
