Ice forming on intake

[LA3222]

Anyone else get this drama? I only jbow it has happened when I open a door to take the trash out and it blows in at me. Clearly the ice is choking the intake and causing the house to depressurise as its not matching the outlet!

@LA3222 I’ll see your ice covered intake and raise you with an almost completely blocked intake vent.
 

 

Looks like a combination of spiders webs and frost. There was no noticeable effect in the house but I was very surprised to see it.

Do you still have the fine mesh behind the coarse mesh?

[Russdl]

Nope. No fine mesh until it reaches my ‘pre filter’ box inside the house.

Here’s a pic from inside the house looking out (taken from inside my pre filter box)

Isn't that a frosted cobweb?
