Carrier 38CKC042 Air Conditioner - Answered Questions & Fixed issues

1.5 ton is the 018. 3 ton is the 036.

3.5 tons 42000 BTUs 16 SEER it's all in the model #

Might be dirty coil so unit is shutting off on high head pressure. Clean coil

I maybe able to help you but you need to clearly tell me again.

Are these reading temps at 2 separate tstats or are you using temp sensors that send the temp back to the stat. It sounds like the sensor is not communicating with the stat. If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

Need model. Number or name. E4 is several different codes for carrier. Likely a temp sensor from what I'm seeing. If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

3&1/2 ton

3&1/2 ton if it is model 38ckco42.

what are you talking about. Turn the thermostat back up. It shouldn't matter what you set the thermostat too because it is just a switch that tells the temperature.

if you look inside the condenser unit outside,see if you see the big reversing valve,if not it is a straight cool,heat, the heat strip ins in the air handler so you would have to take the side panel off and look for the heat stripe,my the way heat pumps also have a aux.heat stripe just in case it does not get cold enough outside,hope this helps you-mike

$125.00 would be a fair price

3 1/2 ton

3 1/2 ton unit the 042 tells me.

A 3.5-ton Carrier CK....OK the run capacitor will be a 370 volt variety, likely 20 bucks tops....given that this is SINGLE capacitor dedicated to the compressor ONLY. A BIT more if (as is likely) it is a 3-terminal compressor/condenser motor capacitor. I assume you mean 'contactor' and this toy should be another $30+/- $5. (Hopefully the diagnosis you got was correct!) That aside, MOST folks in the residential realm use some sort of "flat-rate" system. Replacing the capacitor is ONE job and the contactor is another. If this is a commercial property (OR if you are aligned with a commercial entity), look for a contractor that will make the repair on a "time and materials" basis. One trip, 2 parts...time element should be MINIMAL. Good luck!

This is a 31/2 Ton unit The last 3 digits are the size Example 012 1- Ton, 036 3- Ton unit

Three ton.

Is the furnace fan (indoor fan ) running. If not the problem is with the inside unit. It supplies the control power to operate the entire system and has a control fuse on the circuit board. If it is running but not the outside unit then the problem is outside.

Have him bring the old one back as it is yours. Check for the megaferons it has and the capacitance rating. Problem is hooking up thie wires needs to be done with knowledge of the system. $60 for a capacitor, $1200 for a blown compressor if hooked up wrong. You decide
