Carrier 42G250CF-1 won't blow cold air (on lamp flashes)

My Carrier 42G250CF-1 air conditioner won't blow cold air on the dry or moisture setting. The fan will blow room temperature air. The green, on lamp flashes five times. I'm hoping it it will be a 'simple' solution to fix the problem.

Actually dry and moisture setting cannot cool your room because in that sitting the temperature is limited, you have to set the control in cool or auto.. If the unit is blinking try to reset the unit by disconnecting the power supply for 10 sec.("on" & "off" the circuit breaker), and test the unit.
But if wont work the unit have some defect it may be the thermistor, low freon, or the outdoor unit have some problem. Check if the outdoor and indoor unit is clean or you to call a qualified technician for this problem.

What's the difference between dry and cool setting and when should dry be used

Dry is a dehumidifier option. There is a heating element in the unit to heat the cold air back up. The cold evaporator coil causes the moisture in the air to condense on the coil (this is why the AC leaks water) and the air coming out of the vents will be cold. If you are not wanting to lower the temperature in the room but want to take out the moisture then use DRY. All ACs take the moisture out of the air when they are on COOL. So, COOL drys the air and makes it cold. DRY drys the air but warms it back up before sending it out the vents.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air

I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

Mosture on windows to high or to low setting on Comfor Air 700 humidifier

Hello, If you're getting moisture on the inside of your windows while using your humidifier, you've got the setting too HIGH and you should turn it down at least 2 setting levels to begin with.

Whenever you're using a humidifier, the amount of moisture that it will put into your air will vary depending on how warm or cold the house is. Also, it will depend on whether you not you're using a wood stove to heat with too, as a wood stove will dry out the air faster than conventional heating devices (forced hot air furnance, electric baseboard, etc.).

A wole house humidifier also will vary depending on the outside air temperature changes, so you won't need as much humidification on mild days, as you will on very cold days such as when the outside temps are below freezing.

The good news is that you've discovered the simplest way, for most people, to determine whether to turn your humidifier UP or DOWN - If you're getting moisture on the inside of the home's windows, turn it down, if you're not, you can turn the humidifier up slightly until you just see moisture starting to form on any of your windows (typically this will occur in the colder rooms first), then just turn the setting down one setting level.

The great thing about having a whole house humidifier is that you can actually save on your heating costs, as the moist air makes you feel warmer and will provide you with a more comfortable home in the winter months.

I hope you find this Very Helpful and best regards!

My Carrier Home AC unit stopped blowing cold air today. I opened it up and cleaned everything and didn't notice anything out of place, any ideas?

This could be complicated to resolve over the internet but I'll give it a try. When you stated that it stoped blowing cold air, did it stop blowing air all together? Also is the outside unit rtunning?

Carrier Air Conditioner- not reaching set temperature

if it is set to 76 degrees and its 78 in the house its working fine it is suppose to shut off once it reaches 76 but sometimes there is a 1 or 2 degree differential built ini would keep you filter clean and as long as it blows out cold air i wouldnt be to concerned most airconditioners need yearly cleanings though
