! Gutter Resistance ! ! ! !
In the multi-way connector, located in the refrigerator top flow, it is possible to measure the ohmic resistance the
tension of the current being fed to the gutter resistance.
1. In the refrigerator top flow male connector, measure the value of the ohmic resistance of the gutter resistance
positioning the probing needles of the multimeter, already set to the resistance scale, on the terminals 5-6.

2. In the top flow female connector, next to the cabinet, it will be possible to measure the alternate tension (127V
or 220V) of the current being fed to the gutter resistance on terminals 5-6, while the product is defrosting.
1.4.4 Checking the thermal fuse and the defrost thermostat

IN TERMINALS 2-4 THERE SHOULD BE CONTINUITY TO
GUARANTEE THE PROPER OPERATION OF THE THERMAL FUSE.
THERE SHOULD BE CONTINUITY BETWEEN TERMINALS 1-3 IF THE
TEMPERATURE IN THE BIMETAL DEFROST THERMOSTAT IS BELOW
-6°C WITH A VARIATION OF ±4°C.
THERE WON'T BE CONTINUITY BETWEEN TERMINALS 1-3 IF THE
TEMPERATURE IN THE BIMETAL DEFROST THERMOSTAT IS ABOVE
+25°C WITH A VARIATION OF ±3°C.
