Maintenance Suggestion: When replacing the Onan VR21 Controls, Flight Systems Technical Service recommends replacing the SCR Pack*. You can purchase the SCR pack directly from us or through an Onan dealer.
*Older units may use a multi-component SCR assembly (332-0491) if this has failed, we can convert to use the newer SCR Pack, but the assembly must be sent to our shop.
