You need to get it gassed.There must be a leak of gas somewhere along the copper lines or joints.

SOURCE: My blower motor doesn't blow air out the air ducts why

Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.

SOURCE: Can't get airconditioner to work

Hi

Try to reset the unit by disconnecting the power supply for 10sec. and operate the unit. If wont work then there are some safety device that work or defective. Try counting the blink of your green light so that I can convert the error code.

If no blowing air is coming out to your ac or evaporator fin,your blowing fan is not working.There are several factor to check qualified electrician or ac techician should do this.If you have knowledge on electricity and motor control,beside you should have clamp ammeter to use in trouble shooting of ac electrical circuit.Unplug your ac If there is an opening of blower fan of your ac mostly the top cover open this one locate the wire connection of blowing fan take the color and size.Open the terminal box below the control panel of ac and locate the wire of blowing fan.Check how many leads make sure to make sketch where it was connected from low,medium, and high there is coded color on it,discannect from the terminal, using clamp ammeter set to ohms probe setting R10 check continuinity of winding motor start at common lines(mostly balck color) of one test rod and the other to starting line(mostly red color)take and read the resistance if has a higher resistance your motor is burn out, also with the running line w/c has multple line for speed.If resistance complied to your motor rating or good,If not or burn out replace fun motor.Check your capacitor,doing this set your ohmeter to a higher resistance,connect one red test rod (+) one terminal of capacitor and one black test rod on (-)the other terminal the pointer will deflect steady to higher resistance then reverse the connection of the test rod,the pointer deflect again to higest resistance it will go slow backward setting to zero if you got this result your capacitor is good.But if it does not go set back to zero your capacitor is short.Replaced capaciter.

SOURCE: My AC unit wont blow the cold air.

No, you probably have a bad evaporative fan motor, capacitor or switching. It usually takes a Pro 1/2 hour to track down such a problem with good training.

My portable airconditioner,dimplex dac 3400, the cool function is exactly like the fan function, It doesn't blow cold air??? Do u ever need to regas this machine at any time???


Check the condensor coil to see if it is stopped up. The duct that you run outside to vent the heat that is being removed is attached to it. Does that duct move air at all or a good amount of air?? If coil is stopped up it will restrict air. Is the compressor running? If the coil is stopped up it is likely to overheat the compressor or the compressor start components may of failed. See if you can tell if it is running. It could be a bad compressor. Typically small systems issues do not have problems with freon leaks and you should never have to add freon unless you have a leak. Is there a filter on it check to see if it is stopped up. If it has ran with a dirty filter check the cold evaporator coil to see if it is stopped up. I haven't see. That exact machine but these are basic things to look for.

Rv airconditioner trips breaker


Does it trip when fan only , or when compressor for cool cuts in? Sounds like capacitor perhaps . Get back to me with model number, and whether it's a ducted system, or blows out at ceiling assembly.

Hi, I assume it is ducted, it could be either a flapper door is closed to shut off an area from receiving air, or there is a blockage in the duct (less likely). Also if there is more than one duct attached to the air conditioner then you'll have to check if air is entering all ducts (you may have a problem with the unit).
