Goodman AC fan outside runs, no air inside


You will need a new blower motor if the blower motor is not working. First check to see if the main breaker on the breaker panel is on and 240 volt power is available. If you have a split unit and it is installed in the attic, check to see if the overflow pan is full of water. Find the green control wire and see if it has 24 volts applied to the control card. If 24 volts are available to the control card and the blower motor is not running, you need to call a professional to check the fan control card. If 24 volts is not available to the control card in the air handler, then it may just be a loose green wire in the thermostat or maybe you may need to replace the thermostat if you you can not get 24 volts to the green wire. You can take cover off the thermostat and try jumping a small wire by touching it from the red wire to the green wire. The voltage on the control is only 24 volts on most home units. If this is a commercial unit, be cautious. I have seen 440 volt on one control system. Any voltage >50 volts is considered dangerous and you should consult a trained professional to perform the troubleshooting.
Hope this helps

Air conditioning thermostat not functioning


ab302475-b998-41c7-9c7c-4e106b68e0be.pngGo to your thermostat and look at the FAN switch, it will be in the AUTO position typically.
Set the FAN switch to the ON setting,
by doing this if the fan motor operates you know that the High voltage & the low voltage (24 volt control power) are present.
This saves you from having to go to the breaker panel and checking / resetting the breaker as well as checking the Transformer and automotive type 3 amp control circuit fuse (generally on the circuit board).

If you do not get any fan operation by switching the fan switch to the ON setting, you then will have to determine if the breaker, transformer and aforementioned 3 amp fuse are all good.

You will need a volt meter to test further.
At the thermostat remove the cover thus exposing the thermostats sub base and assorted circuits/wiring.

RED or R
Red is the 24 volt "hot leg" of 24 volt power which originates at the transformer. Red enters the thermostat on the Red or R terminal, some thermostats will have an RC and an RH terminal, these are jumpered together on single transformer systems as they are for Red Cool and Red Heat, without a jumper wire on RC and RH, the Red "hot leg" of the 24 volt control voltage will only energize the terminal its wired to, some stats are battery powered and do not use the transformers 24 volt power (parasitically) to power the thermostat.
If the thermostat is powered by the transformers 24 volt power, there will be a "COMMON" wire on the common terminal of the thermostat, this is the other side of the 24 volt power from the transformer, the side opposite from RED the 24 volt "hot leg"
Common is called common as its the side of power that EVERY
24 volt circuit terminates, or completes its circuit, thus the COMMON designation.
During a Heat call the 24 volt hot leg is sent out via the white/heat terminal to the gas valve etc.
So between terminals Common & White , it should read 24 volts during a call for heat.
Same for Fan which is the Green or G terminal,
Same for Cool which is the Yellow or Y terminal.
If you have no power to these terminals when calling for heat or cool or fan then yes the thermostat is defective and requires replacement.
DO NOT let the RED wire touch ground or the COMMON terminal, this is a direct short and blows the fuse or transformer
if not equipped with fuse protection.

Normally you should read 24 volts between RED and COMMON

Our ruud air conditioner will not go on no fan zero checked the breakers etc, what do i do?


Hello, if the outside unit is not running start at the outside disconnect box and verify if you are getting 240 volts, if you are continue to the contactor coil, check for 24 volts at the contactor coil if there is 24 volts and the contactor does not energize then it must be replaced. If you do not have 24 volts then the low voltage ( thermostat) wiring must be checked out for a short circuit, loose wiring, or the thermostat might be bad. Also, you can check for 24 volts at tjebcontrol board between the r and c terminal if no 24 volts then you have a bad transformer.

My G-air unit does not work at all. It doesn't start


Try the fan switch inthe ON setting rather than the AUTO setting, if it runs, power, both low(24) and high(115 or 230) are present. if not, check breakers and fused outlet if a split system furnace, read for 24 volts at red and common on low voltage terminal board where thermostat wires go on the furnace, if no 24 volts there and poers entering furnace, transformers bad.

Unit will not start up evaperator fan runs


Hi, if your indoor unit is running and you have high voltage to the outdoor unit as the compressor runs, I would check the control wires at the indoor unit, coming from the outdoor unit, and from the thermostat terminals to see if the condenser is wired correctly. I'm not sure what relay you are jumping out to get the compressor to run, and no fan, but if you look at the contactor where your high voltage leads connect, you can energize the contactor by pushing down on the plastic part of the contacts and the outdoor unit fan and all will start. Carefully, use a insulated screwdriver, or I have pushed them down with my finger to see, but be careful! You do have high voltage there or the compressor wouldn't have come on. If all runs when you do this, the thermostat control wires to the contactor have no 24 volt control voltage to it. Check your red and yellow wire connections. If you have a meter, check across the 2- for 24 volts. If you have no low voltage, this is your problem. Go to your indoor control section. If this unit has a circuit control board, look for a plug in type fuse like you would find in your car, a 3 to 5 amp fuse. Make sure its not blown. If the led light is on, it will be good. You have lost the low 24 volt power to run the outdoor unit. Check the wiring there, Red and Yellow. Make sure they are terminated. If none of this helps you or your not at ease doing these checks, call out the contractor and tell them that the outdoor unit will not run if it is new and just installed. They should have done a start up on it. Check the contactor first by pushing it down, it will spark but don't jump as it may scare you some. If all runs, check everything I have told you and you should find the problem. If you have any questions, contact me through this site by my user name, shastalaker7. Keep me posted.
Sincerely,
Shastalaker7

Old a/c package unit add on heat


check your wiring coming from the thermostat should have 24 volts at common terminal and W terminal W is usually used for the heating side. once this is working check to see if you have 24v between common and G which is usually used for the fan motor. if that is good make sure you have full high voltage going to the motor itself find its wires and where they are connected. if it was a low voltage issue and you dont have the 24 volts somewhere in there i was talking about try rewiring the system according to the OEM wiring diagram. You can probably get one on the internet if you google your model number off the unit and its make.

I need to know which wires go into which transformer lead there is a red wire and grey connected together then orange and black together then yellow and black together then black comming from air...


first find out your voltage..240 or 208...then it is 2(two) wires high voltage and ground. Both high voltage should go to transformer one on common lead another to 240 or 208 lead( if you have up to 218 use 208 lead...), transformer ground it self so don't worry about ground. other side of trasformer got 2 wires it will be your 24 volts..normaly it is blue and red( ruud-rheam-goodman red and grey, carrier red and brown)...if you need to know how to "hook it up" low voltage let me kow..totalcarefl@yahoo.com

Brand new unit will not run


You have a bad control board from the onset. This happens sometimes, I have had issues like this before.
