Repair process
Based on the customer's fault description, analyze and determine the repairability of the inverter.
The customer will send/send it to our company for inspection.
Step engineers will specifically detect the fault point, analyze the cause, and give treatment suggestions.
The first step is to issue a test report to the customer, which includes the fault point, treatment method, repair price, and required time.
Solve customers' opinions step by step and wait for customer confirmation. If they agree, repair will be carried out. If they disagree, the original machine will be returned.
Step engineers perform troubleshooting and repair belt motor testing.
Step by step customer payment.
Delivery to customers step by step.
Excellent quality tracking service.
