Hi, guys, happy mothers day.

My pentair master 400, when turns n, it shows 128, then r13, then E06. But the heat won't start.
I replaced stack flue sensor. Same thing.
Is that any other issues maybe? Board show SFS LED3 light on.

Maybe I just had bad luck, ordered a bad sensor?

Thank you for your input!!!

Pentair tech support suggests testing their new ones before installation. The sensor may be tested with an ohm meter (3.8 MegOhms @ 77F).

If you decide to get a new SFS, check the stack flue temp when you get it back together and running to confirm that the stack flue temps are where they should be, and not too high.
