the burner for blockages. Clear any
blockages.
2. Inspect the burner slots for clogs. Clean
any that are clogged.
3. Turn on the refrigerator in gas mode.
4. Verify that the flame from the burner is
blue and steady.
5. If the burner cannot be unclogged or if it
appears damaged, replace the burner.
Climate Control Heater
Does condensation form in the fresh food
compartment or around the door frame?
1. Test the climate control heater wiring for
resistance.
2. If the reading is out of specification,
replace the defective wire.
Communication Wire Harness

interior light is on?
Do the panel lights not turn on?
Is E0 or E1 displayed? (New Generation

1. Test each wire of the communication wire
harness to confirm that there is continuity
through the wire.
2. Test each wire of the communication
wire harness to confirm that there is no
continuity to the chassis ground or to the
case of the refrigerator.
3. If the communication wire harness fails
either test, replace it.
