Freezer door got stuck open on a box of corn dogs for about 7 hours on a 90 degree day. Temps were 65 degrees in both sides when we got home. Now it won't get colder than 58 degrees on either side.
Just unplugged for 20 min and cleaned coils.
What is next?

Did you clean the coils under the unit with soap and then spray off with hose nozzle? This is very important. Also, you can advance the defrost timer and start the defrost cycle when you put the back on again after cleaning the coils.
