    Lennox furnace blower rattling noise

    I hav a Lennox G5OUH series gas furnace. I recently noticed a funny noise coming from the vents when it was running. I went downstairs and took a look at the furnice. All the lights are operating normaly and the noise sounds like a bearing or something is rattling loose. It seems to be emanating from where the blower is. It only happens when the blower turns on.

    Anyone know of any common problems with the blowers on these Lennox furnices. Any suggestions or input would be greatly appreciated.
    Thanks

    After further research. The noise is coming from the combustion air inducer. The noise stops when this unit stops, the blower is still on. I"m just looking for some insight, I'm not trying to fix it myself. I just want to be informed when I call in the morning.

    you will want to have a service provider come out and check it, could be as simple as a insect nest in the wheel of the combustion blower that needs to be cleaned and removed, to the inducer itself out of balance or bad bearings, there is a contractor locator on this site that will tell you if there are any members in your area that can repair it for you!

    Thanks hvacman. I'm hoping it will just be a simple cleaning procedure by the tech. What should I expect to pay? $100-$200?

    Just this weekend we had a fairly large hurricane like weather for 2-3 days. 50-60mph sustained winds and gust up to 75mph. Could these winds have blown something down the exhaust vent into the inducer?
    Thanks

    Well the tech found some dirt and debris in there but nothing major. He said the inducer fan is out of balance, it has a wobble. He thinks this is what was causing the vibration/rattling sound. $********for parts/labor.

    Pricing not allowed, please

    were not allowed to discuss pricing in these post, because differnt regions have differnt rates, you will want to edit out the pricing in your post or a moderator will come along and take it out for you,

    Glad that you have found out what the issue is

    Sorry about that. I"ve included a video of the inducer wobble. Seems like this is the problem. What do you guys think?

    yes , thats appears to be the issue, have your tech replace it now, before it goes out on a friday night when its 10 degrees outside, that will save you the afterhours overtime rates!

    The oem 24W95 lennox inducer motor assembly costs about $$$$
    But I found a PACKARD 66501 Lennox Direct Replacement Draft Inducer 115 Volts 3000 RPM for $$$$

    Has anyone used a packard Inducer?

    Considering this machine burns fuel and heats your home, I wouldn't use anything other than the oem parts. If the aftermarket part doesn't perform to the mfg specs you will be endangering the lives of you and your family. Aftermarket parts have there place. Just not as a key component of the combustion cycle
