SERVICE MANUAL23www.norcold.comFault Codes, cont’d.codeWITH BEEPINGALARMNOR000124A-5rSrMeaning:The Power Board detected an internal fault. This fault can be resetby powering the refrigerator OFF and back ON. Should this faultcontinue to be displayed after being reset, the Power Board shouldbe replaced. This fault can be displayed in ANY MODE.Verify:■ Igniter Spark Sense electrode is not touching the burner(shorted to ground).■ Wire from P1-10 (12VDC out to gas valve) is not shorted toground.■ For example, if the wire were to be pinched somewhere andthe insulation covering torn, this would allow the bare wire toshort to ground and this fault will be displayed.■ If the above steps check good and this error continues, replacethe power board.Lo dc without alarmMeaning:The Power Board has determined the DC input voltage is less than10.5 VDC. Anytime the DC input voltage falls below 10.5 VDC andthe low DC voltage fault is displayed the divider, perimeter, andflapper heaters are turned OFF. This fault can be displayed in ANYMODE. This fault will be cleared and the divider, perimeter, andflapper heaters will be turned back ON when the DC input voltageis ≥11.5VDC.Verify:■ That the battery charging equipment of the vehicle is opera-tional.■ That the AC/DC converter is operational (if applicable).■ If voltage is within range, replace power board.code codecodeNOR000124A-lodc-woalarncodecodeWITH BEEPINGALARMcodeWITH BEEPINGALARMNOR000124A-lodc-woalarnGASLo dc without alarm while in GAS ModeMeaning:The refrigerator attempted to ignite or re-ignite the burner when theDC input voltage was less than 10.0 VDC. The gas valve/igniteroutputs are inhibited when there is a call for cooling and the DCvoltage is less than 10.0 VDC. Should there be a call for coolingwhile the DC input voltage is greater than 10.0 VDC and the DCinput voltage then falls below 10.0 VDC, the gas valve will remainenergized and no fault will be displayed. This fault will automaticallyreset and the gas valve/igniter outputs will be allowed to operateonce the DC input voltage is >10.5 VDC. This fault can only bedisplayed in the Auto and Manual GAS modes.Verify:■ That the battery charging equipment of the vehicle is opera-tional.■ That the AC/DC converter is operational (if applicable).■ Contact Customer Service for further instructions.codeWITH BEEPINGALARMcodeWITH BEEPINGALARMcodeLo dc with alarmMeaning:The DC voltage to the refrigerator is less than 8.5 volts DC. Alloutputs are inhibited. This fault will automatically reset and outputswill be allowed to operate once the DC input voltage rises above9.0 VDC. This fault can be displayed in ANY MODE.Verify:■ That the battery charging equipment of the vehicle is opera-tional.■ That the AC/DC converter is operational (if applicable).■ If voltage is within range, replace power board.Remember that the fault can not becleared until the DC input voltage is≥11.5VDC.ATTENTION!
