All refrigerators need to be defrosted every few hours. Older
refrigerators used a simple, inexpensive, and very reliable mechanical
timer. In many models made today, the defrost cycle, temperature
control, and other hoo-hahs are all handled by an over-priced and highly
failure-prone electronic circuit board. GE calls theirs a
motherboard.
On GE Profile and Arctica refrigerators, the motherboard is located on
the back of the refrigerator, behind the metal panel. Remove the panel
and you'll see the board, shown here (click pic for larger view).
To put the refrigerator into defrost mode, use a jumper wire with
alligator clips (you can buy a bag of 'em at Radio Shack for a buck
two-eighty) to jumper the two terminals shown here in this pic.
This will put the refrigerator into defrost mode and makes it easy to
troubleshoot defrost system problems. While in defrost mode, you can
check to see if the electric heaters on the evaporator are getting hot.
If not, then use your
light stick to see if you're getting voltage to the heater wires. If voltage isn't making it to the heaters, then the possibilities are:
- open defrost thermostat
- bad connection between the muthaboard and the defrost components in the freezer
- bad motherboard
OTOH, if you are getting voltage at the defrost heater but no heat,
then replace the defrost heaters. You'll need to order the set based on
your model number, which you can do
ratcheer.
