The a/c unit outside doesnt come on but the fan inside of the house is blowing, the unit is not cooling the house. I have a goodman unit.
Hi, this is a split system Goodman. With the j36 in the model number, that tells me it is a 3 1/2 ton unit. If the outdoor condensing unit is off and doing nothing at all, no fan on top running, no compressor or anything, it sounds as though you have lost power to it. The high voltage to the outdoor unit is seperate from the indoor unit. When it is not running, you have only warm air from the indoor unit. Before I have you do anything, go out to the unit. Take a water hose being careful not to bend the fins on the coil, and wash just the coil very good. If its dirty, it can cause the pressures in the system to rise very high and blow a fuse or trip a breaker. When you are done washing it, you should have a electrical box mounted on the wall that feeds power to this unit. First, find your main breaker box to your home. It should be where the meter is. Find it and it will have several different breakers in it. They may or may not be marked. Look for a double - pole 30 to 40 amp breaker that should say a/c, if it was marked. If not, look and touch them, it will be 2 breakers together and feel if they are tripped. If so, turn it off with a hard motion. Then, back on the same way. Watch to see if it holds and does not trip on you. If its ok, go to the outdoor unit. Make sure the thermostat is on auto/cool and turned way down for it to come on. If it was a breaker and its running, more then likely the dirt from coil caused it to over amp and trip. Now, if there is power and breaker is on but still not on, open the box at the unit. It may have a pull out type plug, or breakers. If it has a breaker, turn it off and on like the other. If it doesn't, behind a plastic panel you will have 2- fuses. Turn off power at main box breaker, and remove both fuses. They are cheap, so go get 2 at a hardware store and replace them. You can have them ohmed out to see if one was bad. After installing the new ones and you turn it on, and all is good, that was your problem. May sure you have power to this outside unit. If it was a blown fuse or tripped breaker and this continues to happen, you may have a internal compressor or condenser fan motor problem. Try the things I have said first. This may be the only problem you have. I do this for a living, 33 years and a licensed contractor. Please keep me posted and I will continue to help you if you need me. Let me know after you check everything.
