I have a goodman central air unit CK36-1A. The other day I noticed the fan on the outside unit was not running and the unit was hot and seemed louder than usual. It took the fan out and noticed that one of the wires (brown) to the fan had been nicked by the fan. I cut out the nick spliced the wire back together, and taped them to the inside of the unit so they would not get knocked again and when I started the unit the fan was running slower than normal so so I shut it down. It seems to me like I am only getting 110 instead of 220. What should I be looking for to try and repair.

On of the common problem with centralized A/C unit is a bad condenser fan. I have known people who called an ac technician to fix their ac because of a bad condenser fan and suggested replacing the whole unit! Costing them a lot of money when all it needed was a 50 dollars condenser fan! If the condenser fan do not run or it runs only when you give it a push, it'sbad. You will also notice that it is vey hot. When replacing a condenser fan you may want to replace the starting capacitor too. Replacing a condenser fan is not very hard, just make sure that the power to the ac unit is turned off at the breaker box. Confirm that the wires are not live by using a meter or an ac tester. The fan motor are held with brakets sometimes just screws. Most fan you can buy that has reversible rotation by just reversing the plug. Make sure it is blowing upwards. If not reverse the rotation. So if you notice that the unit is not putting out cold enough air and you went outside and noticed the compressor running but not the fan, turn off the AC right away and do not use it untill the fan is replaced. Running the unit with a defective fan can damage the compressor caused by overheating.
Their is a fan relay on combo gas heat and central air conditioning. The reason is for heat you need slower fan speed than for air. How do they do it? They use a relay to shift the fan from low for to high for ac. More HERE
It sure sounds like the out side condenser fan has gone out.If you need to Fix a water hose to run on it like a spray fanning out over the out side coils(condenser)and try and see if it will cool.It will do the trick,until you get it fixed on week days.If I can help,let me know.>>>firstname.lastname@example.org
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
Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.
