Heating Elements
There are seven heating elements on this refrigerator - a Fresh Food Heater (not accessible), a Flapper Heater between
the two Fresh Food Doors, Two Fill Tube Heaters, an Ice Maker Heater (The Flapper, Fill Tube Heaters and Ice Maker
Heater are in a parallel circuit), a Freezer Defrost Heater, and a Drain Heater (not accessible)(The Defrost and Drain
Heaters are in a parallel circuit). There are three defrost profiles: When the refrigerator is in Quick Freeze Mode, the
Defrost Element will energize every 10hrs for 60 minutes or until the Evap. thermistor reads 50OF/10OC. In Door Open
Mode the Defrost Element will energize every 38hrs or when the compressor has been running for 28hrs. Again, it will
run for 60 minutes or until the Evap thermistor reads 50OF/10OC. In Door Closed Mode the Defrost Element will energize
every 50hrs and will run for only 5 minutes, or until 50OF/10OC is reached.
