Support FAQs

How can I get technical support from RHM?

Our USA after-sales team maintains daily contact with our factories in China and follows up customer questions and NCRs directly with the factory’s assigned project managers and design engineers.

What is the reaction time to customer support requests?

A customer service response is typically less than 2 days. This includes customer requests for additional information, technical clarifications or follow-up on any field installation issues. Customer NCRs will initiate an internal Quality 8D Report investigation process with a final resolution proposed within 2 weeks of the reported problem.
