Check your furnace. It should have a flashing light wth a list of codes. determine which code you have and you can reset it. last time mine did this the furnace door was cracked open. The furnace has the blower in it and thats why your not getting cold air, that is if the outside is running as you said.

Check with a voltmeter to see if the unit is getting power. Check to see if power supply is putting out power at it's wires, and also the fan wires to see if it is getting power. Check for any relays. they can be checked with ohmmeter. If fan is getting power but not operating, than it is faulty. If no power, then relay or power supply or board is faulty.

Ruud UAKA-030JAZ fan spins, not blowing cold air


there are 3 things to be considered,first,if the compressor motor `s connectors are having loose,it gives a hi ampere to your RELAY that can cause to its contacts being fried,second,the compressor motor itself is gaining a hi ampere already i.e. having unusual sound that can cause heavy friction inside the turning mechanism and third the last but not the least,maybe this time,the tubes or the compressor itself having very small holes that causes to the refrigerant to escape and it doesn`t gives off cold air.

Its possible that the contactor that closes to start the outdoor unit is not pulling in and passing power. You are hearing the coil humming since it is getting control power. Also first check that breaker for outdoor unit is not tripped

You may have a bad condenser fan motor or a bad capacitor for that motor. If the compressor is running in the outside unit but the fan is not then it is most likely one of those two components that has failed. Consider calling a service tech to test it and see where the problem is.

My LG LWHD1200FR air conditioner turns on, but the fan doesn't spin and no cold air comes out. What's the problem? How do I fix this?


Which fan doesnt spin the inside fan or outside fan? If its the outside fan try replacing the dual capacitor for the fan and the compressor. First take the fan blade and see if it spins freely if you spin it and it stops immedietly the fan bearings are bad. If it spins freely replace dual capacitor. If trhis helps please rate me and do a testimonial.

Inside fan turns on when outside unit is in defrost mode when heat is selected. This causes it to blow cold air for about 10 to 15 minutes prior to the outside fan starting.


The inside fan will run while the unit is in defrost. The electric heat strips should kick on to help prevent you from feeling this cold air. When the unit is in defrost it is essentially running in the A/C mode. You should make sure the electric heat elements are working then go from there.

When we turn on our split AC, outside unit is not turning ON


The blinking light is because the unit is waiting for the outdoor unit to come on. If in heating mode, the indoor fan will not run before enough pressure and therefore heat has built up. You should check that the indoor air return sensor is not faulty and therefore preventing the outdoor unit from coming on.

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

Cold Air Penetrating from around & thru GE Zoneline 2100 Unit


There is a baffle/damper that allows outside fresh air to flow through the unit. This is only supposed to be open in cooling mode when the outside temp is moderate, or whenever you want just fresh air and fan operation.

Find the lever that controlls the baffle.

Some units have a switch in the control panel for this.

Fan not turning outside


Is the outside compressor running? Check the fuses in the outside disconnect by the outside condensing unit. Also check the breaker for the A/C in the main power panel.
