Daikin EKVDX / VAM Aircon UJ-38 Error Code
Use this Daikin EKVDX / VAM UJ-38 error code guide to confirm the source table meaning, capture the reporting equipment and model, and match the service manual before diagnosis.
What does Daikin UJ-38 mean?
Daikin EKVDX / VAM UJ-38 is listed as the paired VAM reported A6-29 for the R32 application in EKVDX / VAM R32 ventilation source row. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
This page imports only the loaded source meaning; use the matching manual for its diagnostic contents and checks.
The reporting equipment and exact installed model determine which service procedure applies.
A cause should be recorded only after the matching service-manual checks are completed.
What to do now
Use these steps to record evidence and match the installed model to its service manual before diagnosis or a repair quote.
Record UJ-38 and match the service manual
Record UJ-38 and stop there; the source table gives no customer reset procedure. Arrange diagnosis with the matching service manual.
No manufacturer reset steps listed for UJ-38
Capture the complete UJ-38 error code and model stickers first. The source table lists the meaning but no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.
