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 in the amount of $200 is required to cover the initial unit evaluation. Once evaluated, an estimated repair quote will be provided for parts and labor. Labor will be charged at a rate of $150 per hour. 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.
