The original relay was rated for 1,000,000 cycles. The machine was in a commercial setting for ~14 years where it was left on 24/7 year-round and then ran here 24/7 for 8 months out of the year for 7 years. Using the avg cycle time as measured here that means the relay had almost 2,000,000 cycles on it when it died. I'd say it's fair to say the relay was over-built and that their stated duty life was pretty fair reflection of what to expect in reality.
