Warranty and RMA Services

Product Warranty

Phasetronics, Inc., dba Motortronics, (hereinafter “Company”) warrants the products to be free from defects in material and/or workmanship for a period of one (1) year from the date of sale, or a maximum of 18 months from the date of manufacture (if no sales records are available) as indicated by the unit’s date code, unless otherwise stated. The Company reserves the right to repair or replace any malfunctioning units or sub-assemblies under warranty at the Company’ sole option.

Warranty repairs may be performed at the Company’s facility, in the field by a factory-authorized technician, or by the customer only with prior approval and at the specific direction of the Company’s Technical Services personnel. During the 1 year period, malfunctions of the control boards will be dealt with by replacement of the Modular Control Assembly (MCA), which contains the User Interface Panel, Digital Control Unit, Bypass control (if any), and Communications Interface. The MCA is designed to be replaced quickly without the need for tools (plug-in), and as such will constitute the majority of warranty replacements.

When Technical Services has determined the nature of the problem and that sending replacement parts or assemblies can repair the unit, a purchase order for replacement parts and/or assemblies is required. Upon receiving the purchase order a Return Material Authorization (RMA) will be issued for the defective parts or assemblies. If any, components or assemblies are received at the factory without the proper RMA documentation, the shipment(s) will be refused.

When the replacement parts and/or assemblies are received and evaluated at the factory, any warranty determination will result in a credit being issued for the replacement parts and/or assemblies that were shipped out. As an alternative a Technical Services representative can provide a RMA if the unit is not needed for immediate operation. The unit and/or components will be evaluated upon return, repaired at the factory and returned. In either circumstance, freight/shipping costs are the responsibility of the purchaser.


Company is not responsible for the misuse or misapplication of its products, intentional or otherwise. Improper application, installation, failure to provide safety devices or protective measures, or operation above its ratings, and failure to properly maintain or service products are all beyond the control and responsibility of the Company. Under no circumstances shall the Company be liable for loss of profits, indirect, incidental, special, consequential, or other similar damages arising out of the misuse, misapplication, or failure to maintain the Company’s products.
