What is the C14 error on Felicity?

C14 on a Felicity unit means: Output loss.. It can appear on 14 different devices in the Felicity catalog. The cause and recommended fix are listed for each device on this page.

Can I clear the C14 code myself?

It depends on the severity. Warning-level codes can usually be cleared by following the recommended fix. Fault and critical codes often require checking the source condition first; if the code returns immediately after restart, escalate to authorized service.

Is the C14 fix the same on every device?

The cause is consistent — it's the same protection logic. The exact fix wording can differ per device because each official manual addresses model-specific context (input ranges, parallel-config notes, firmware revisions). Use the per-device section that matches your unit.
