Easiest way is to take everything out, put the food in coolers, then open the door on a hot summer day. Put a tray below the freezer front to catch the water and empty it frequently. Beats trying to chip the ice and you don’t risk damaging the interior finish..Some years back, during a period of 110 plus weather in northern california, the sample freezer where the fish bios on the Salmon/Scott District put their fish, decided to up and quit. It was in a shed near the office. They found out about a week after it shut down because of the liquid leaking out from the freezer door. I pity the folks who had to clean that.
