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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBox end\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSpa packs usually carry more than one probe, a temperature sensor and a separate high limit sensor.
