On July 22 RIOC issued this advisory:

Please be advised the South Tram Cabin is running at a reduced capacity until further notice.

On July 26 RIOC issued this advisory

The South Cabin is temporary out of service. The north Cabin is unaffected .

I inquired of Roosevelt Island Operating Corp ( RIOC ) Vice President of Operations Fernando Martinez:

The South Tram Cabin has been experiencing difficulty recently with several service advisories issues regarding disruption in service.

What is the problem?

Mr. Martinez replied:

During the recent heat wave, the mechanical rooms became extremely hot. We ran the Tram at reduced capacity in order not to over work the motors. The disruption of service on the South Tram was due to a part failure. The part was immediately replaced and tested, and the Tram was returned to service.
