GLFH21F8HBB Frigidaire Freezer - Instructions

The electronic control did not defrost the coils. I had to use a screw driver to pry the unit off of the door. The instructions on line said use a putty knife or butter knife. I bent both trying to remove it. I suggest using a heavy duty screw driver. Once the unit was removed it was simple to put the new one back. It just snapped back in place. I also replaced the thermostat just in case. It's like buying $11.50 insurance. That required removing several screws and unsnapping the thermostat and unplugging the wires. Then putting the new thermostat back and plugging in the wires. Very easy to change the thermostat.

Unplug freezer let stand all night to defrost. Remove the tray cover which is located on the upper back area inside the freezer.( 3 twist fittings remove it ). Remove the upper stainless steel panel which is secured with 6 screws. This will drop down exposing the condenser. Note all the wires and fan will stay attached to the stainless steel panel, this panel will drop down no need to unplug anything. On the left upper side next to the condenser you will see the thermostat. Two color coded wires. Remove the thermostat and install the new one at the same location.
