Didn’t hear any difference in sound, but she mentioned it was sounding like it was going into overdrive after running fine after a couple minutes. Remembered we wired in a jumper between w1 & w2, so I removed it & didn’t notice a difference as well. Mentioned to her if the loud sound were to happen again to call us again once it’s happening so we could catch it while it’s active. Other than that no issues to report.
