Question about Carrier 38CKC030 Air Conditioner

2 Answers

I have a Carrier 5 ton Air Conditioner -five years old. I turn on the thermostat and the blower comes on in the house then the compressor engages, but the fan does start. I can manuelly, start outside fan by using a long screw driver to turn the blades. Then the fan begins to turn slowly until it reach a faster speed. But I do not beleive that the fan is turning as fast as it use to. I go back into the house and after 15 to 20 minutes the temperture has not dropped. It apprears to stay a the the temp. What's wrong and where do I go from here.

Sounds like a bad run capacitor in the condenser. Turn off power at disconnect outside. Remove panel to access electrical. Verify cap size (5 ton carrier) likely 70 or 80/5 MFD. Be sure to take a picture of the wiring before removing cap, obviously wire back same way. Turn power back on. I'm sure it will be fine as far as the cooling inside once cap is replaced Good Luck!!

Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know [email protected]

SOURCE: My Carrier AC fan will not turn, only blows out warm air.

Breaker has popped either at breaker box or at the safety shut off switch. Fuses are blown or the sending unit has popped.

SOURCE: Carrier air conditioner cycles on and off

The compressor/condenser is being called all the time. The reason it goes off is because the evaporator (indoors) freezes up when the fan is told to turn off by the thermostat. This further cooling lowers the low side pressure below the low limit switch point turning off the compressor unit.
Solution: Make sure the thermostat is wired correctly. Green wire is usually the compressor wire but maybe not.

I have a Carrier Weathermaker model #38tdb060300 A/C system. How many tons is that? It is 11 yrs old, capacitor exploded and compressor is blown. Needing to replace.


Looks like a 5 ton unit. However, you might be better off finding a R-22 condensing unit to replace the entire outside unit. Reason being, if you just replace the compressor, you get a one year warranty. If you replace the whole outside unit, you get a 5 year warranty. You can replace the outside unit with any manufacturer, as long as it is the same tonnage and type (heat pump/air conditioner/single stage/ 2 stage ...).

What are the reasons a carrier air conditioner would not be cooling?


A leak in the system, low on refrigerant, a bad pressure switch, a bad thermostat.

My 5 ton Goodman Heat Pump won't go into heat or ac mode. Fan won't turn on. No noise from compressor. System is 1 1/2 yeras old.


Easy: Turn the "fan" switch to on at the thermostat and see if the blower starts. If no start, check breaker at breaker box. Check service disconnect at or near the air handler. With the breaker and/or service disconnect OFF check the 3 or 5 amp fuse inside the top cover in the air handler.
Not so easy: (You must know what you are doing for this part or let an HVAC Tech do it for you) Open thermostat and firmly jump the Y and R terminals to see if you get the compressor to start for no more than 30 seconds. (don't do it more than once.) Jump the G and R terminals to see if you get the blower to start. If so, u have a bad thermostat. If not, check the transformer inside the same cover in air handler for proper voltage. (24V. Make sure you also get 220 on the opposite side of the transformer)
If the blower comes on, but the heat pump doesnt start, open the side cover of the heat pump, with the thermostat on cool, and the temp. setting as low as possible for at least 10 minutes see if the contactor is pulled in. If so, check the capacitor and see if it's blown out. Be super careful these systems operate with 220v and the amperes are enough to kill you if you make a simple mistake.

Possible Contactor Issue


Sounds like a bad fan switch in your unit. That unit has a fan board in it that is time delay on and off. Turn the fan to the on position and let it run all the time. If it keeps temp and does not shut off it is the fan realy board. The board also controls the compressor. Check that first and then the tsat. Russ

I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.


It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

Is the unit over five years old? If so it is a fair price for conpressor, parts, labor and refrigerant. Have him give you a firm price. If it is an older unit, say over 10 years, and you have the money replace the complete system

Weather King 10AJA6001AH Air Conditioner with bad compressor


If it is five years old it is either right in or out of warranty a service tech can determine this through the serial number. If not the unit is only a little bit more to replace than the compressor. A replacement compressor is only warrantied for one year verses a unit replacement with five years on the compressor and one year parts and labor.

How to reset 5 minute blower delay for carrier 4 ton central system-instlalled 1995


There are potentially 3 time delay relays in this system.

1) Many digital Thermostats come with compressor ON delays that are not serviceable.
2) There is an accesory manual Time delay available for this unit. It is also a compressor ON delay. (located in the electrical compartment of the condenser)
3) Most newer furnaces have a blower OFF delay (set manually at the circuit board.

I have the technical manual for this unit if you need it.
