Here are five ways to begin troubleshooting your variable frequency drive. Number one, inspect for physical damage. Did you let the smoke out? Number two, verify incoming power. Did something trip? Number three, validate your fault codes. What is your VFD trying to tell you? Number four, check run and frequency reference signals. If something happened here, it will not run. So try remote mode.
