Ductwork rattle when heats on - 2670mk

[ThePirateQAR]

Sounds like the noise is coming from behind the bathroom shower area. It’s so bad it wakes us up every time it comes on. Anyone else have this issue?

The furnace in the 2670MK is located just forward of the shower. All of the ducts (there are four) from the furnace snake out and go to the various registers. I suspect one of those ducts has come loose or is not secured (zip tied) thus flopping around when the heat comes on.

You might be able to peak behind the closet drawers and see the furnace and the ducts. Below is where I'm referencing (from a YouTube video).

The furnace the ducts use a twist lock connection to the back for the ducts to attach to the back of the furnace. While doing another project on my trailer I found one loose. the retainer screw was missing. I hope it is an easy fix for you. If you find you need to use tape get the high temperature foil tape rated for furnace connections. Std duct tape may melt and stink based on comment in other threads..
