It's the latest misfortune to hit the service, which has had to stop on three separate occasions over the past year due to cracks in the trams.
Trams were unable run between Wednesbury Great Western St and Bull Street in Birmingham from 7am until just past noon, meaning the service could only operate between Wolverhampton and Wednesbury.
However a 20-minute service into Birmingham was restored shortly after midday.
