Sunfire Factory Service

If you suspect your Sunfire product has a problem, please do everything you can to confirm it before calling for service. This includes reading through the Troubleshooting Guide of your user's manual, also see the Frequently Asked Questions on this site. A large percentage of products returned for service are tested by our technicians and coded "NTF" or No Trouble Found, which usually means the problem lay somewhere else in the system. 

Return Authorization

To obtain factory service for your Sunfire product, call Tech Support at (800) 472-5555 6:00 AM to 4:00 PM, Pacific Standard Time, M-F to explain the problem and request a RA (Return Authorization) number. We do not issue RA numbers via email. 

Please have the following information available when you call.

  • Model Number of the Unit
  • Serial Number Located either on the gold label on the back of the unit or on the the bottom of the unit. If this is hard to access you can also find it on the product shipping carton.
  • Detailed description of problem. Including an explanation as to the conditions in which the problem was first noticed. For example, after a power outage, the center channel and subwoofer no longer work. If the failure is intermittent, how often does it reoccur?
  • Contact Name, Address (return shipping address, no P.O boxes) , Phone (daytime contact number)
  • Date of Purchase All warranty repairs must be accompanied with a dated proof of purchase. A dated sales invoice from an authorized dealer is acceptable proof of original purchase date. If a customer does not have the original invoice, we will add six months to the date of manufacture (first four digits of serial number) to determine the start of the warranty period and if the product is to be serviced under warranty.

Include a legible note with your name, shipping address (no P.O. boxes), contact phone number, RA number, and a detailed description of the problem, including how our technicians can duplicate it. For warranty repairs please include a copy of the original sales invoice.
