The 10 Amp Fuse by Master Spas is a replacement part made to go in your home spa’s PC board. The PC board supplies power to the entire spa, so replacing one of its fuses is sometimes a simple fix for issues that arise with your spa or its features.
The sensor assembly is specifically designed to go with Down East Spas and Legend Series Master Spas (select 1996-1999 models). It is a replacement for Balboa Dual Sensor Assembly with Temperature and Hi-Limit Sensor. Compatible with all Balboa systems that use this type of sensor.
