Common faults and treatment methods of blast drying oven:No matter what industry's instruments and equipment fail more or less during use, drying ovens are no exception. Here are common failures and how to deal with them:Phenomenon 

1: There is no response when the device is turned onCause of failure: The power supply does not meet the requirementsMaintenance method: ask an electrician to assist in solving itCause of failure: electric heating pipe failureMaintenance method: the heating wire is short-circuited to replace the heating tube, and the heating wire is blown to replace the heating wirePhenomenon 

2: The temperature cannot riseCause of failure: If the time runs to the timing set value, the fan does not rotate, resulting in no heating and no temperature upMaintenance method: readjust the timing setting valueCause of failure: The fan operation is faultyMaintenance method: replace the fanPhenomenon three, there is heating, the inner tank can not circulate, the degree rises slowlyCause of failure: The motor does not runMaintenance method: replace the motorPhenomenon 

4, the control board shows that there is a difference between the temperature and the thermometer measurementCause of failure: Inaccurate thermometer measurementsMaintenance method: The thermometer needs to be re-measured after being inspected and qualified by the testing departmentCause of failure: The measuring installation position of the thermometer is deviatedMaintenance method: adjust the position of the thermometer to the center position of the inner cavity, which cannot be directly placed on the shelf for measurement.Phenomenon 

5: The temperature shows abnormal jumping or staticCause of failure: There is a problem with the temperature sensorRepair method: replace the matching sensor with a new one
