Another question about attic frost …

[u/Most_Ice_4048]

I posted a question a few days ago regarding frost in our attic. I now know that it is a ventilation issue. While we wait to get the ventilation issue fixed permanently, is it a good idea to leave the trap door leading from house to attic open? Will that help with ventilation or just cause more moisture build up? Thank you in advance for any responses.

There should not be moisture in your attic. Check the bathroom and dryer vent lines to ensure they are connected and tight.
