20 Most Recent Carrier 38CKC060 Air Conditioner Questions & Answers

Hello, There are a few ways to tell, you csn usually find out by the compressors model # or they have a tool that is called a refrigerant " identifier" on the market.

carrier model 42SD7C giving ER03 .what is solution

The capacitor starts the motor. You would have had some other problem had the motor not started. The A/C ran until the failing capacitor no longer provided the ability to start the motor at which point your A/C died. My A/C bulged both its capacitors 2+yrs ago and it's been running ever since they were replaced, no problem. I think you're OK.

Are you sure you have high voltage going to the unit? One wire from fan lands on top left of contactor, the other two go to C and Fan on capacitor. Manually push in contactor, if no fan than no high voltage. If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

According to the reading sound like compressor is working fine .There are other issue that contribute to no cooling and the main one is dirty filters so check your filter to see if it's dirty and clean or replaced it .
If filter is fine then you might have dirty evaporator or condenser coil so clean those out too .
Does this unit have 2 compressor and if it does is the 2 compressor running

I am not understanding exactly what is happening with your unit. You say it only runs for 4 hours a day and then say that after 4 hours the outside unit shut off. But you don't describe the condition of the outside unit! Is there ice on your outside unit after it runs for four hours or is it so hot that the housing would fry an egg? Since it works for four hours and then stops working, I would guess that ice forms on the condenser grill which tells the thermostat that your air is much colder than it actually is. Then it takes time for the ice to melt off again. Am I close? If so this condition is usually caused by your unit being low on freon making everything work harder. But it could also mean that you have a leak in the system somewhere. But it shouldn't be much of a leak or it wouldn't run for the 4 hours.
I would recommend you charge it to the correct level and then check for leaks.

What is the make and model of the thermostat?

the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly

No , this is a 6 ton Carrier unit , and the SEER is 10

IT'S COOL ONLY MODEL..

that is a condenser, or air conditioner. cooling only, outdoor unit

If the refrigerant has been accurately charged and diagnosed, I would look for an air restriction. Check your filter first of all. It sounds like it may still be trying to freeze up. Make sure all the vents are at least a little open and the return grill is not blocked. In the Rocky mountain region we like to see around 44- 50 deg. at the vents. 65 would tell us that everything is not ok.

Yes, these are very simple to install. I'm not sure about your exact model but generally you just have to remove the top of the unit and the grill slides right up and out. It's only held in by the down pressure of the top being screwed on. Hope thus Helps : )
