Pete is correct,
The model series of the appliance helps more...It is most likely an NT series Suburban...I sent the service manual to that entire series to the document center a few weeks back..Donna D. has put it there, it has the trouble shooting points the service guy uses with a detailed series of procedures to service this unit, its not the owners manual, you would need to order this one to get it and its there for free.
If there are questions after reading that or about those tests then post the issues, there are some spooks in the machine to talk about in the design but it will shorten the explanations to a short novel over the long one I can be known for. Within its info is a wonderful detailed step by step of operations in sequence of order.
The comments about freaky stuff that just happens the manual does dot cover is where it gets interesting for me, spiders in some areas, mud dubber wasps in others, this year I had Aficanized bees who thought it was a great hive, two spotted talking geckos who were ground up and a match box car.
