Maintenance Suggestion: When replacing the Onan VR21 Controls, Flight Systems Technical Service recommends replacing the SCR Pack*.
*Older units may use a VR22 multi-component SCR assembly (305D491, 305-0491, or 305-0489) – if this has failed, we can convert to use the newer SCR Pack, but the assembly must be sent to our shop.
Must send VR22 for upgrade
