The ac was not working and found that the clutch coil was bad. Replaced it and it worked fine for a day, about 3 hours of driving. what could cause the coil to fail? I didn't check pressures after the coil was replaced. I am thinking of replacing it again but would like some hope that I can figure out what is causing the coil to fail. What should I check after I replace it?

The only idea I have is that I hit a dog about a month ago and the condenser was slightly bent and this is restricting flow or reducing cooling causing the compressor to run longer and overheating the coil

 

If your system is low on freon the compressor will not kick on

 

I solved my problem. I feel so stupid. When I put the coil in, I did not fully set the split ring that holds it in place. It slipped out and rubbed against the clutch and cut into it. I even had problems getting the second coil to lock in place. I would try to gently pry the coil up and the split ring would not hold. I finally had to tap the split ring down into the slot with a punch and hammer.

The first time i did it on the car. The second time I had the compressor on the bench.
