I have a YE-5-NA board. I moved the hot tub, and now it trips the GFI. While troubleshooting, I found that L1 (220v configuration) shorts to neutral and ground at the input terminals. I removed all connections to the board and still had the GFI trip. I removed the heater element and transformer connections and the GFI did not trip. I reconnected the heating elements but not the transformer, and the GFI remained clear. If I add the transformer back, the GFI trips. The transformer checks out good with correct input and output voltage. Any suggestions would be helpful to continue troubleshooting.

To troubleshoot a Gecko Y Series YE-5-NA board that trips the GFI when the transformer is connected, follow these steps:

1. Check the Heater and Element – A shorted heater or element is a common cause. Disconnect the heater and see if the GFI still trips.
2. Isolate Accessories – Unplug each accessory (heater, pump, blower, light) one by one. After disconnecting each, check if the GFI holds. This helps identify the faulty component.
3. Inspect for Water Damage – Look for water leaks on motors, lights, or other components that might cause a short.
4. Test the Transformer – Ensure the transformer and its fuse are functioning properly. If the fuse is blown, replace it before testing further.
5. Measure Voltage – Use a meter set to volts AC:
- Check the primary side (white wire to black wire) for 120V.
- Check the secondary side (yellow wire as common) for expected voltages (e.g., yellow to blue ~12V, yellow to red ~another voltage).
6. Replace the Faulty Component – If a specific component is causing the trip, replace it.

If the issue persists after these steps, further diagnosis may be needed.
