Operating Instructions and InstallationSamsung Electronics 4-21Troubleshooting4-3-11 Outdoor temperature sensor error1. Inspection items1) Are the sensors connected properly?2) Are the sensors located properly?3) Do the resistance values of the sensors satisfy each temperature?2. Inspection orderYesYesYesReplace temperature sensorNoReconnect the temperature sensorconnectorNoPower offReconnect the temperature sensorconnectorNoNoYesAre connectorsproperly connected to therelevant colors?Are temperature sensorsconnected without separation?When measuringthe resistance of both sides with a singletemperature sensor, does it indicate 10KΩ atroom temperature of 25°C?YesReplace PCB after turning off the powerNoAfter assemblingthe temperature sensors on PCB checkthe voltage of both sides. Do they indicateDC1V~DC4V?Is there ashort circuit or defective contact inthe sensor wires?Replace temperature sensor after turningoff the powerYesPower onReplace PCB after turning off the powerex) Room temperature24°C ~ resistance 10.28kΩCurrenttemperature(°C)Resistance(KΩ)Currenttemperature(°C)Resistance(KΩ)70 4 20 1260 5 10 2050 6 0 3040 7 -10 4030 8Eiffiel_29331A_10.22.08.indd 21 2008-10-22 17:04:05
