Problem Furnace Rattle on startup and shutdown

[scotticus614]

Hi All,

I am having an issue with a camper I just recently purchased. Last night I was doing my first test run in the camper. I noticed that as the furnace started up and shut down I was getting a very loud rattling noise. Once the furnace fully started the noise would be gone. Likewise once the shutdown sequence ended the noise would also be gone. I have a 2023 Viking 2108st. The furnace brand appears to be Suburban. Any help would be greatly appreciated! I would love to be able to fix this issue myself instead of having to bring it to a shop. I have linked videos below.

May have to take it apart and see if something is in the fan cage, or if, it needs to be replaced.
