Hi, Nick. I'm writing to you about a job. I managed to log into the diagnostic mod. I did the test as indicated in techsheets, all the values specified in it were acceptable. I also checked the new and old parts for resistance, they are also fine. I'm at a dead end, I don't know what to do with this unit next, and the customer wants to call the warranty service and ask for a new unit, because there were other technicians there before me and it's been a long time. I also read the forums and did not find the necessary information about this unit.
