Repair man came out and could not find the problem He reset to control panel and the fridge/freezer both seem to be working fine now. However it did take several days for the fridge temp to drop to what it was before this all started (my scientific data for this is a tall glass of milk).

Then tonight I could hear puffs coming from the freezer. I could hear them from the bottom tray of the fridge and from the freezer. Almost sounded like steam being released in short puffs.

Any thoughts on what these short puffs might be?

Any thoughts on how to pull error codes for this fridge? (Per the manual I have to use my phone when I call the service center.)
