Hello Techs,
I’m working on a new unit with a horizontal right coil and need some guidance diagnosing an issue where water is entering the secondary port and triggering a system shutdown. Under normal conditions, the safety switch should remain dry, so this behavior is unexpected.
This problem appears to be occurring on multiple recent installations, so I’m trying to determine whether it is related to installation setup, drainage, coil orientation, or another underlying issue.
If anyone has experienced this before, I would appreciate any insights, troubleshooting steps, or recommended corrective actions to resolve it.
