Hi, I'm new here and a novice at fixing my pool equipment. I'm hoping some savvy pool experts can help me in layman's terms:
My Pentair keeps burning thermal fuses. The first time it looked extremely melted, and a technician came to replace the fuse & cleaned all the burners. He mentioned it may be a life issue for the heater itself, which is about 15 years old. After his "fix", the unit was working fine, but now a week later, the fuse isn't working again (however it doesn't look melted at all, I can just bypass to see it's failed).
I've ordered replacement fuses to avoid purchasing a whole new heater. Any suggestions on how to avoid these issues? I have lots of spiders and the unit is outside (with lots of clearance around it). Should I verify certain parts are clean? Am I doomed to buy a new heater just as we leave swimming season?
Thanks in advance!
