To update you all - You were right when you said they 'understand', even without the correct jargon. So, we've tried the Crydom Relay, but that didn't fix the problem. But they had heard about this issue, and apparently, it's not unique to my machine. So, Mike in the electronics dept. is now sending out yet another 'fix'. Our 3rd attempt. Frustrating! I'm glad my husband was an electronics tech at his job before retiring, as I'd be lost otherwise.
Thanks again for your suggestions.
