TOTO THP3403 – Frequently Asked Questions
1) What is TOTO part THP3403?
THP3403 is a TOTO replacement sensor, the flat horizontal fan-shape type, used with a ventilation fan. It is a service part, so you order it by the THP3403 number when the original sensor on the fan has failed rather than replacing the whole unit.
2) Is the TOTO THP3403 sensor for a toilet flush valve or for a fan?
It's a fan part, not a flushometer part. The THP3403 is catalogued for ventilation fan use, so if you're chasing a no-touch flush valve sensor this is the wrong part number.
3) Do I need to specify a finish or version when ordering the TOTO THP3403 sensor?
No options to pick. THP3403 is sold as a single configuration, so the part number is the whole order. Property managers stocking spares for multiple restrooms can order against that one number.
4) What is the manufacturer part number for the TOTO flat horizontal fan sensor?
THP3403 is the TOTO MPN. Quote that number to your distributor; the descriptive name (sensor, fan shape) alone won't pull the right part since TOTO uses several sensor variants across its accessory line.
