Need help identifying a plastic part – Electrolux dryer

[Sarah M]

Hi everyone,

I found this plastic part while cleaning my Electrolux EDH3684PDE tumble dryer, but I’m not sure it actually belongs to it.

Marking: A00188301
Material: PP-TD40
Size: about 25 × 15 × 5 cm, light grey plastic with ribs and side clips.

It doesn’t match any filter or air duct part I can find online.
Does anyone recognize what it might be or which appliance it comes from?

Any help appreciated!

Thanks,
Sarah M
