Question about Goodman CLQ36AR49 Air Conditioner
The starter capacitor went out on my outside ac unit I had it replaced everything worked fine for about 2 weeks and the the red wire burnt off at the capacitor got that fixed and all was fine again 2 weeks after that the same thing happen but this time it was the yellow wire what could be the problem? I am leaning toward the compessor going bad any help would be appreciater it is a goodman 5 ton unit and it is only 5 years old
Hi, and yes if this capacitor is getting hot enough to burn off wires, you are drawing to many amps at your compressor causing this. Did the old capacitor you replaced leak any oil, or was it swollen and deformed? I have seen a compressor last less then 6 months. If you had a amp probe the clamp around, you could check the running load amps, (R. L. A. ) at each leg of the compressor to see what each one was pulling. Like the R terminal, 11.8, C, 9.7, and the S or start, 8.9 amps and compare it to the data plate on the outdoor unit which tells you what it will be, like 21.7R.L.A., just a guess on yours. If it was much higher, you would know you have a problem. Whens the last time the outdoor coil was cleaned?? It should be cleaned every year as the head pressure will build in the system putting a load on the compressor and will cause these kinds of problems. Before I would condem the compressor, kill the power and take your water hose to the coil and give it a good washing. If dirty, it could bring the internal head pressures down by 50 p.s.i.! Do this to see if it takes care of the problem.If you had a service tech out to replace the cap, he should have put his manifold gauges on it and cleaned this coil for you. Be careful not to bend the aluminum fins down with to much pressure. If this is a dual run cap, it would be for the fan and compressor. It will have 3- sets of 3 to 4 spades coming out the top, 3 in a row marked Fan, C for common, and Herm for compressor. With a dirty coil, it will also cause this fan to run to hot and take out the capacitor. Do this for me and I believe this will solve the problem if the fan and compressor seem to be running quite and cooling good. Keep me posted on this. My gut tells me its a dirty coil causing this problem. Please be kind when rating me, that would be nice of you. I will be here if you need me.
Sincerely, and have a great 4th,

My opinion is simple! The wires went bad on the first capacitor and were not replaced. Now after a fresh capacitor was installed the wires just could not hold up any longer! Thats is why the red wire did not burn off the second time and it was a different wire....the yellow! The next wire that is going to go bad is the Brown wire if it was a three wire capacitor. Hope this helps explain the problem! Always replace the wires after a cap is blown!

It sounds like the wires are not connected tightly, if you put the capacitor on yourself make sure you take a pair of pliers and crimp the male connector more snug. A burnt wire does not mean bad compressor,it
could mean poor wiring connections
