Re: MTD Yardman Transaxle Rebuild
the early system 2000 boiler was PLC, then in around 1999 or 2001 they switch to downloadable system upgrade boards.....neat thing was that our service override boards worked on all models, even series 1, so we could just switch boards and run tests through the system to locate faults and many times I would leave my board in the customers boiler till I have the replacement part so they would have heat and hot water for the weekend.......I'm sure if I go downstairs and check in the file cabinet I will find my service board still there.
