Product details
This is the Sundance Spas SD6600-167 box end temperature sensor in the new style, listed to fit the 800, 600, 600-S and 400S series spas.
What it does
The temperature sensor is what tells the control pack how warm the water actually is. Everything downstream of that reading depends on it: when the heater fires, when it stops, and what the topside panel shows you. When the sensor drifts or fails outright, the pack acts on bad information, and the symptoms look like a heater problem rather than a sensor problem.
Box end
The box end version terminates at a connector that plugs into the control box, which makes the changeover a matter of unplugging the old sensor and routing the new one rather than cutting into wiring.
Before you order
Spa packs usually carry more than one probe, a temperature sensor and a separate high limit sensor. Check which one your control is reporting, and compare the connector against the sensor in the spa if the tub is older, since this is the new style part.
