I have a fairly new AC system installed. The outside unit is 3 years old, the air handler is 2 years old. They were replaced a year apart due to failure. Last summer, the dual run capacitor on the outside unit swelled and failed, causing the compressor to be able to start, but the fan wouldn't run. It only did it a couple of times over a 24 hour period before it was discovered. The dual capacitor was replaced, and the unit kicked on and ran fine for the remainder of the year.
Fast forward to 7 days ago or so. The AC will kick on at the preset temperature, and it will begin to cool; however, the light dim every 3-4 minutes like the compressor is trying to kick back on. When the outside unit first comes on at temp, the lights dim considerably more than what I'd deem to be "normal". The unit then does its cycle of off/on for about a half-dozen cycles, then it runs fine until it gets back down to the proper temperature. I should probably note that the outside fan continues to run unaffected at full speed during this entire process.
The air handler is in the attic--it is a Bryant unit, and seems to be fine. The outside unit is a Fedders, which I now understand is considered to be bottom of the line. Our haste to get the unit swapped out on a 105 degree day cost us dearly. What could be causing the problem, and what are my repair options?
