Generator runs but the automatic transfer switch does not transfer load to the WEN generator during an outage.

Safety first: Ensure the utility is de‑energized or that the ATS is in a safe position before working inside. Lock out and tag out both utility and generator sources as required by local codes.

• Check generator present signal: Confirm that the WEN controller indicates proper voltage and frequency and that any "generator ready" output to the ATS is active.
• Inspect ATS mechanism: With all power off, open the ATS enclosure. Manually operate the transfer mechanism (if allowed by the manufacturer) to ensure it moves freely. Lubricate pivot points lightly if recommended.
• Check ATS control fuses: Locate and test low‑voltage fuses in the ATS. Replace any blown ATS control fuse with the correct rating.
• Verify control wiring: Confirm that the control wires from the WEN generator to the ATS are intact and correctly landed.
• Replace ATS board if needed: If the mechanism is free and wiring is correct but the ATS does not respond, the ATS control board may be defective and require replacement.
