Contributor wa0mge recently responded to my query about a noisy ECM module under my bathroom sink.
Your response got me thinking. My A/C units also seemed to do a lot of loading/shedding. I turned the ECC off for front and back, then sprayed contact cleaner into the temperature setpoint slots and worked the setpoint slides up and down a bunch of times. Furnaces and A/C units now work perfectly, and no more noise from the ECM module. Hope you saved your old module for a spare, seems to be just a minor corrosion problem.
