The panel may be held in place by retainer clips
or screws. Remove the screws or depress the retainer clips with
a small screwdriver. On some older top freezers it is necessary
to remove the plastic molding to access the freezer floor. Removal
of that molding can be tricky -never force it. If you decide to
remove it, you do so at your own risk - it is prone to breaking.
Try warming it first with a warm, wet towel.
The thermostat is connected by two wires. The
wires are connected with slip on connectors or a wiring harness.
Firmly pull the connectors or harness off of the terminals (do
not pull on the wire). You may need to use a pair of needle-nose
pliers to remove the connectors. Inspect the connectors and the
terminals for corrosion. If the connectors are corroded they should
be replaced.
Test the thermostat for continuity
using a multitester.
Set the multitester to the ohms setting X1. Place a probe on each
terminal. The multitester should display a reading of zero when
the thermostat is cold and a reading of infinity when it is warm
(40 to 90 degrees F depending on the model). If the thermostat
does not pass this test it should be replaced.
