System froze because the fan motor stopped working, could be that the fan motor is bad, or if it is a PSC it could be a bad capacitor.

Check that the fanmotor can spin freely. If not, can be caused by seized bearing on left side of fanblade, or foreign object, insect nest stuck in fanblade. If however it spins freely, check that fanmotor is being supplied with voltage (you sound technically capable of operating a volt meter). If power is supplied, fanmotor is faulty and needs replacing. If no voltage, problem lies with the pc board. If you know someone who is capable let them check the relays on the board. Also you can check that all plug on connectors are making good connection.

SOURCE: Blowing hot air, compressor not kicking on, just fan ? ?

are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.

SOURCE: Unit seems to work fine, but NO COLD!!!

If the compressor kicks on and runs fine, this usually indicates that the freon in the system is good. Is there anything else that can obstruct the air into the unit or into the cabin? I believe that this refrigerant will be R-22, and may be difficult or impossible to purchase without a license. I also think R-22 is sold in cylinders larger than you'd want. Check in your unit, though. If, by some slim chance, it is R134a, you CAN buy and install this yourself, but, again, I doubt it is. Your best bet would be to have a local technician put the gauges on it and recharge it. Be sure to check for leaks. If you're losing refrigerant, you need to get the leak stopped, or you are going to just throw your money away.
Best regards, --W/D--

SOURCE: 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

Have ice build up on line leading into outside unit and ice buidup on inside units on my goodman air conditioner


Turn the system off on the thermostat and set the fan to "ON", this will thaw the ice faster if it hasn't already. When the system has completely thawed, which could take hours sometimes, depending on how bad it's frozen, then turn system back to "Cool" and start these checks>

1. Make sure filters are clean!
2. Make sure there is proper airflow through vents.
3. Make sure outside condenser fan motor is running.

If you have either no or minimal airflow, check the indoor blower to make sure it's working, if it is, the evaporator coil is dirty restricting the airflow. Be sure the system is thawed because the ice will also block the airflow!

If the condenser fan motor is not running, either the capacitor or the fan motor will need to be replaced.

If your filters are clean, you have good airflow through the house, and everything comes on like it should, it will most likely be the charge of refrigerant in the system is too low and you have a leak somewhere. If you have to have it charged, be sure the system is thawed before the technician gets there, he will not be able to do anything while it's froze.

Hope this helps and good luck!

Coils are freezing in the room air conditioner


Hello my name is Heath it will be my pleasure to assist you. First thing to do is turn the unit off and check the filter then if the filter is okay check to see if the blower comes on when you put the fan switch on the thermostat from auto to on. If the blower isn't coming on then there could be a problem with the blower motor. If the motor is running then turn the system to cool and turn the setting down to where the air should be on. Then check the outside unit and be sure the outside unit is running if the outside unit is not running go to the house panel box and check the breaker to see if any of them are tripped or off. If there off turn them on and check the outside unit again. If all is running and you get no air flow through the vents then the coil could be frozen. If the unit is frozen turn the thermostat to off and leave the indoor blower on by leaving the fan switch in the on position for a couple hours till it thaws. If the unit froze up then there could be a problem with the a/c system most likely low on refrigerant as a result of a leak. I would have it leak tested and repaired if this is the case.

Not cooling looked at inside behind filter and it is frozen


Hi,

A frozen evaporator coil means one of two things, a lack of air flow or low refrigerant (freon).

Make sure the filter is clean and the coils are free of dust and dirt. If the unit blows good air (strong flow on high) when it first starts up and then freezes you are low on refrigerant and need to have it recharged.

We just turned on our central air conditioner last night. today the temp of the house was 80 degrees. someone in the household placed the tempature on 70 degrees cool on auto. we have not felt any air...


Did you hear the indoor unit running (the fan blowing)? If so, there's a good chance that either the filter is plugged or more likely, the evaporator coil is iced up and preventing any air from flowing into the dwelling.

This points to a refrigeration issue with the unit - possibly a leak or low refrigerant charge.

You should turn the A/C off and leave it off for a day. Then just turn the indoor unit fan on by selecting the fan "on" setting on your thermostat. If you feel air coming out of the vents, then the evaporator coil was probably frozen.

If you are not an HVAC tech, it's time to call for professional help.

Air conditioner problems


Check your filters first. Replace if needed. Also check that the evaporator fan or blower fan in the furnace is running. If this does not fix it you most likely have a low refrigerant charge.

It may be the small vent fan motor on the inside if the control panel. When the noise begins remove the panel and you may be able to catch it in the act.

Friedrich air conditioning - inside unit ice build up


Hi, Reduced air flow, low on freon or being continuously run during cooler weather such as at night. Some people turn their thermostat on 60 thinking that it will help get it cooler faster. They freeze up at night and don't get a chance to thaw during the day. It needs set no lower than 75 or so. The evaporator may be dirty. Don't know a lot about your particular unit but if the outside unit has the compressor and refrigerant lines running to it, The large refrigerant line should sweat all the way to the compressor if its fully charged. Please rate me if I have helped. Good luck kstfas
