Attempted to fire up the furnace in my camp (hasn't been used in 10 years). Burner motor would not turn. Through some simple investigation it was determined that the pump was seized up. Just ordered a new A2VA-7116 pump on line. Total cost was $55 with taxes and delivery. Disassembled the old one to find out why it didn't work. Everything was gummed up and corroded. It took 10 minutes to remove the old one so I expect it should take 10 minutes to install the new one (two bolts and two flair fittings). All other components on the furnace work (once pump was removed) Hope this was the only problem! If not then I'll still be ahead of the game if a professional needs to be called in. S far as replacing the pump it appears so simple even a caveman could do it! Extending the exhaust flu through the new roof that has been built-not quite so simple I bet! That will require some research to make it safe and code compliant.
