Picture this: you've got the pool sparkling clean, the lounge chairs out, and the sun shining—then your heater throws a code because the stack flue sensor crapped out. We've all been there, staring at a cold pool wondering how much it'll cost to fix. The Funmit 42002-0024S stack flue sensor is your straightforward solution, designed as a direct replacement for Pentair Sta-Rite MasterTemp and Max-E-Therm pool and spa heaters.
The stack flue sensor monitors exhaust gases to ensure safe, efficient operation. When it fails, your heater might shut down prematurely, overheat, or just not perform right, leaving you with chilly water even on mild days. This sensor steps in with spot-on accuracy, using the same specs as the OEM part (42002-0024S) to keep everything running smooth. It's built tough to handle the heat and moisture of pool environments, lasting through seasons of heavy use.
Installation is a breeze if you're handy with basic tools—no need for a pro every time. Locate the sensor on the heater's flue stack, disconnect the wires, unscrew the old one, and thread in the new. Takes about 15-20 minutes, and you'll have peace of mind knowing your SR200, SR333, or SR400 is back online. Pro tip: check it during your annual heater tune-up to catch issues early.
With this sensor in place, your heater fires up consistently, maintaining that perfect 82-85°F for laps or family floats. It prevents those surprise error codes that interrupt summer barbecues or weekend soaks. Pool maintenance just got simpler, saving you from emergency service calls that run $200+. Whether you're running a backyard oasis or a small spa, reliable parts like this keep the fun going without the frustration.
Grab the Funmit stack flue sensor today and get back to what matters—enjoying your pool on your terms. It's the small part that makes a big difference in heater performance and longevity.
