If you are experiencing a problem with one of your units and would like to return it to ZMicro for evaluation and/or repair, please submit an online Return Merchandise Authorization (RMA) request below

The following information will be required to submit your request:

  • Model number
  • Serial number
  • Description of Problem
  • Point of contact

Once submitted, a member of our Customer Service team will process your RMA request and if it is determined that your product needs to be returned for replacement or repair, a RMA number will be issued, along with the warranty status and return instructions.

Request RMA

Note: An RMA number is required to return a product regardless of the reason for the return

For additional questions, please contact us via email at customer.service@zmicro.com or by calling 858-831-7040 M – F, 8am – 5pm PST.



Repair fees are determined by the warranty status of a unit. The warranty status of a unit will be researched at the time of the RMA request and based on the status will indicate whether or not repair fees are required. Upon re­ceiving the product and it is determined the product was damaged by an end user, the warranty may be voided and repair fees may be incurred.


If a unit is under warranty, there will not be a charge for labor/parts. Once repaired, the unit will be returned via ground shipment. If express shipment is requested, a purchase order or shipping account number is required to cover the expedited shipping fees.

Out of Warranty

If a unit is out of warranty, a purchase order will be required to cover the initial cost of evaluation. Once evaluated, an estimated repair quote will be provided for parts and labor.  Repair of the unit will begin upon authorization of the repair. The parts replaced in an out of war­ranty product will be warranted for 30 days.

We will accept all units for repair assessment, however; some models are considered End-Of-Life. As a result, it is possible the parts to repair these products may no longer be available. Once the failure has been determined, you will be no­tified if the unit is irreparable, and is deemed Beyond Economical Repair.
