Flame blowin' in the wind...
Thanks for the advice guys. Others I have talked to agree with your assessment. The furnace worked fine prior to replacement of a noisy inducer motor. The repairman was called out again and claimed that there was a piece of gasket material blocking the air flow. It seemed fine until he left and then reverted back to the same problem. I have been thinking that he put in the wrong inducer motor, but on the other hand, with all of the jarring of the system, particles may have dislodged and are now blocking orifices. If I decide to clean the system, I will definitely call in a pro because it looks to be a real bear to get the burners out. They are integrated into a chassis that holds the gas piping, so the chassis, gas piping to and through the valve, as well as the valve need to be removed. The furnace is 12 years old so an alternative is to just replace it. It is on the 2nd floor of all places and is quite noisy. Can anyone recommend a super quiet brand?
