Well, now that I have the vents unblocked and know the operational characteristics, I will watch and see if it happens again.
If it does, then I have a parts problem.
If not, then it’s fixed!
Yay!
Sometimes ya gotta be happy with little victories, eh?
We had a blocked vent on the garage fridge back in the summer. Wife had added some packaged meat and blocked the air flow. Moved that package and it was fixed.
