3. Excessive ice on the battery If the rubber valve remains open since the air outside the freezer compartment is humid it penetrates inside and forms too much ice on the battery The valve remains open if there are foreign bodies or if it loses elasticity therefore in the first case it is necessary to remove the foreign bodies while in the second case it is necessary to replace the rubber valve R600a NOFROST REFRIGERATORS 21 22 Failed defrosting If no defrosting cycle occurs the possible causes could be Sequence POSSIBLE HOW TO VERIFY CORRECTIVE ACTION n CAUSES 1 One or both Disconnect the heaters connectors If the value of stylus heater is not defrosting heaters and check with the tester the about 490 Q and the armored one are interrupted correct heater value to the is not about 480 Q then replace the connector clamps interrupted heater 2 One or both Freeze the battery then unplug the If the heater value is Q thermal overload appliance disconnect the thermal infinite open circuit replace the cut out switches Switches connector and check with thermal switches If the heater are open the tester the electrical continuity of value is 0 O then check sequence the thermal switches to the no 3 connector clamps 3 Timer blocked or Unplug the appliance place the If the heater value a and b are faulty thermostat knob on ON then access timer box and measure with the tester the electrical co
