A relay can be welded "closed" and cause this. It is in the outside half of the air conditioner. If you have printed circuit boards, it's a lot harder to guess what's wrong from over here, but I've actually seen this problem when it was caused by a relay. Of course, I am assuming no person has been in there changing wires around.

Open it up, find the relay where one of the fan wires is going, give it a sharp rap with a screw driver handle. If that fixes it, replace the relay.

Need the tons for my unit. its really old and i cant read it on the side i have the model number it is 50ym042310 and it is a 230 volt unit. i know its a carrier because i amable to still see the brand...


The number you are referring to as your 'model number' is a number I don't recognize; maybe it's the SN or something - I don't know.
But that other number - "38CKC042" -------'is' --- your model number and the size of your AC is 42,000 Btu or 3.5 tons.

My carrier 38CKC (60) is blowing hot air. The fan seems to be running fine. Is it the condenser coil, or just needs freon? How do I know? The unit is about 8 years old and never been serviced (I know...I...


Assuming the outdoor unit is running, make sure the fan motor on top is turning and the compressor is running. They both must operate for the unit to function.

The easiest and most common problems:
1. Condenser coil is stopped up with dirt. The condenser coil is the radiator looking coil that wraps around nearly the whole outdoor unit. It can be washed out with water and a sprayer, just make sure you don't bend the aluminum fins and disconnect power before washing it out.
2. Low on refrigerant. If you don't have guages you can't check the refrigerant on your own. If the fan and compressor are running , feel the bigger copper line coming from the outdoor unit going into the furnace. It should be cold. If not you can either be low on refrigerant or the compressor valves are weak.

Hope this helps. If the unit is not running outside, repost and I will try to diagnose differently.

First time starting a/c this season, display is lit but no air is blowing. Fan outside is on. Batteries changed, still no air. System is only @ 2 years old. Stat model - TH3110D1008. Thanks.


Set the thermostat FAN setting to FAN ON to verify the fan working.
If it works in the FAN ON position the fan motor is OK and you have a bad fan relay.
If it does not work you should check the fan motor capacitor.
At 2 years old the unit is still under warranty for parts.

Heat comes on when the temperature setting calls for cool.


getting heat in the cooling mode leans toward the reversing valve in the outside unit. it changes the flow of refergerint so that the hot air you get outside in the summer is blown inside in the winter. another possibility is that the reversing valve isn't getting 24v check to see if you have 24v at O and C either at the t-stat, furnace, or the outside unit. if you check at the furnace rember the safty switch for the lower door if that switch is open you will have no power. i would look at the t stat first if you have 24v there go to the outside . 24v present outside will mean a bad valve or board, no 24v means a bad or broken conection in the control wire between the stat and the outside unit(usally the orange wire)

Carrier 38CKC048 unit outside does not turned off when the furnance fan is turned off by the thermostat, I believe its the contact switch that is sticking what part do I need to replace, and can I do it or...


do you own a multi meter? do you know how to use one? if not call some one.
does the unit keep running outside if you turn off the furnace power switch. if it keeps running it the contactor in the condensing unit. if it shuts off it is your t-stat.

Bryant-Carrier Furnace Fan Stays On


I suspect a bad fan relay or bad fan control. Maybe the longer the control or relay is in the on position the more chance of it sticking on.

Have 20 year old split carrier system, tried to turn a/c on today nothing, no fan, blower, do have power to a/c both in and out. Any help


first thing is that if u in fact have voltage to the furnace and condensing unit check the primary and secondary sides of the transformer on the furnace. if you dont have 120 on the xfrmr test the door switch and 120 v connection to outlet. if you are good there check the secondary side of the transformer and see if u have 24 volts leaving the trans. if you have 24 v leaving the trans. you should have 24 to the stat if there is not a blown fuse on the control board. check the transformer for power. if there is power there see if theres a fuse on the control board at the furnace. if thats not blown check stat operation pull stat off and jump r to y which should engage cooling. jump r to g which should engage fan. this is all of course if u have a standard a/c and not a heat pump unit. if u can jump cooling or fan replace the stat. let me know more when u get there.

Turn the power to the indoor unit off. Remove the cover where the fan is. Feel the motor of the fan. If it is very hot the bearings have likely gone out. If the fan is cool to the touch I would call a service company because you likely have an electrical problem that will require some training to solve.

I have a carrier infinity system. On the thermostat it reads "sens error" where the outdoor temp is normally displayed. The inside unit is running but the outside unit is not. Any suggestions?


A burned or pitted contactor will/can cause a unit to not run. Outside fan. Just thinking out loud. Start with low voltage check at t.stat then check outside low volt. Set t.stat to on. If fan engages at least your transformer is good. Next set calling for cool. Drop t.stat 68-70. If nothing happens go outside and with a screwdriver depress the contactor in. If fan and compressor kicks in change the contactor. If contactor is pulled in check outside fan. Remove the wires from the compressor and see if the fan will run . If it does you have eliminated start components as good. The compressor has to be check. It needs to be ohmed out. Turn off power at disconnect. Pull the cover on the compressor. Check between pins; then pins to ground. Open or infinite is good.Have you checked fuses. Like small 3-5 amp fuses
