Control Transformer Rework
Bosch Thermotechnology has been informed by the manufacturer that some of its transformers with integral circuit breaker, FHP part number T-111-603-026, may not open if an over-current condition occurs. Although it is highly unlikely, an over-current condition might create an over-heating situation with a potential of a fire and/ or shock hazard. No such incidents have been reported.

Bosch has identified 128 shipped units that may contain the affected transformer. These units were shipped between September 2014 and November 2014. All affected serial numbers are listed in the PDF below. Units not on the list are not affected. This rework does not impact spare parts shipped from Bosch.
