1. The heating tube connection is too loose. Please tighten the connection.
2. Heating tube / temperature controller / power tube damage. Please check if one of the nozzles works well, but the other one cannot be heated. Please troubleshoot by one of the following methods
a. Open the machine case and find out the connectors of the two heating tubes, exchange the two connectors and heat the nozzle again. If the failed one works now, it means one heating tube is broken and needs to be replaced.
b. If after exchanging the two heating tubes, the failed nozzle still can’t work, please exchange the heating tubes back and try to exchange the connection of the two temperature controllers. Then heat the nozzle again. If the failed nozzle works, it means one temperature controller is broken and needs to be replaced.
3. If the above two don’t work, it means the problem is with the power tube on the main board. Replace the power tube.
