Greetings Trouble Free Pool members.
This is my first post. I am troubleshooting an issue with my Pentair MasterTemp 400 that is immediately tripping the GFCI breaker. This started happening after a rain or heavy moisture in the air. I checked inside the heater and discovered that mice had chewed the ends of some of the wiring in the area around the terminal board. I was able to put new connectors on the areas with damage but am still experiencing the issue. I can also see where the mice had urinated on a lot if the electrical components (transformer, blower, ignition control module). I cleaned up all of the grounds and removed and cleaned the Fenwal ignition control module as well. I have used a multimeter to check for leaking voltage and I see that terminal F2 on the Fenwal has about 40 milivolts when I check for DC current to ground. When I unplug the blower at the harness connection, the heater no longer trips the GFCI breaker. None of my other breakers within my intellitouch system ever trip. Only the GGCI breaker on the sub panel. Any ideas on what next steps I should take? Thank you for any assistance with this.
