Refrigerator contanct failture, breakage of
wire, short-circuit, inferior Refrigerator
SENSOR and others.
Indicating a defect when the temp sensing
of Refrigerator SENOSR is above
(149°F/65 °C) and below (-58 °F/-50 °C).
The voltage should be within the range of
4.7V~0.6V between MAIN PCB CN30 #
8 and #9.

sensor and others.
Indicating a defect when the temp sensing
of peripheral temp SENOSR is above
(149°F/65 °C) and below (-58 °F/-50 °C).
The voltage should be within the range of
4.7V~0.6V between MAIN PCB CN31 #
1 and #4.
Freezer SENSOR 3 Freezer "MAX"
