My 6 month old Whirlpool standup freezer is not freezing anymore.
The thermometer is only going to 42 inside and some food is defrosting and some is solid.
THat seems to indicate lack of air flow, so I pulled out all of the food and found that vent in the back was iced over.
I pulled off the cover and found plenty of ice on the coils.
Link to picture of frozen over coils.
Could this possibly of happened if my daughter left the door slightly open for a few hours a couple of days ago or do I probably have a defrost problem?
Any pointers on what to check first if I have a defrost problem?
