2004 Pace Arrow Electronic Control Module

[Bob (WA0MQE)]

Has anyone had any problems with the ECM, Electronic Control Module chattering when the furnances are running. (apparently there's a relay for the two furnances). Mine will start doing this after about 30 minutes to an hour of the rear furnance being turned on. It doesn't do it when the front furnance is on. I had the dealer check it out and they, supposedly, changed out the ECM board but it's still not working.

I've also spoke with the ECM board manufacturer and gotten a couple of ideas. But I was wondering if anyone else has had this problem and if so how did you get it corrected?
