3 amp control board circuit breaker. Provides a temporary, emergency fix for control boards that continue to blow fuses or are shorted out. Supco recommends to use the Li'L Popper as a "temporary fix" only, until the original control board can be replaced.
Use the Supco SmarTester to troubleshoot heating system problems. Remove blown fuse and plug LI'L Popper into the fuse receptacle on the control board.
Simply push the button to reset the control board.
