Why won't my Ampcontrol Relay close and indicates an EC fault?
- JJames SnyderAug 18, 2025
If an Ampcontrol Relay won't close and shows an EC fault, it could be due to a faulty pilot circuit, such as an open, high resistance, or shorted to earth. Try operating the relay with a dummy plug if in diode mode. If the issue persists, the pilot fuse should be checked. If the relay remains faulty after these checks, consider replacing it.
