blower fan ticking
Hello,
When changing my filter on my air conditioner / forced air furnace a piece of cardboard from the old filter got into the blower fan. Now the fan makes a ticking or rubbing sound. I reached inside to rotate the fan by hand and it seems to be out of balance or slightly rubbing on the housing or the cardboard is still in the fan. How do I get direct access to the blower or how do I get the blower out to inspect this more thoroughly? The ticking is not that load in the basement but it echoes throughout the duct work upstairs. I'd like to fix this problem as easily and inexpensively as possible. The furnace is a Lennox about ten years old.
Thank you for any help,
Tom

On most of the furnace blowers. Look up at the top of the blower where it goes in to the furnace. Most of the time there are just some screws that hole it up there other time take the screws out and the whole blower will like slide out on rails. Some of the lennox had 4 nuts to take off and the blower would drop down.
Turn the power off first. Get the paper out of there before it gets up in the furnace section.

ed is right
depending on brand and type (heat pump or gas) the blower assembly generally is on a grooved slide, and only 2 or in some cases 4 screws hold the whole thing in place. look for oil ports on the motor when you pull it out, it may have some depending on age
