I have been having problems with my furnace. Every year to year and a half, I have to replace the housing that holds the draft inducer motor to the furnace because it cracks. Is this a common problem for this furnace? It had to be installed upside down because it is replacing a boiler. Is there an updated part that might fix the problem?

Maybe some photo`s would help us to understand,, what is upside down? The furnace or the inducer housing? If the furnace is a multi-directional furnace that shouldn`t matter.
