{"product_id":"sundance-jacuzzi-hi-limit-sensor-6600-168","title":"Sundance®\/Jacuzzi® Hi-Limit Sensor w\/ Box-End Connectors, 22 in – 6600-168","description":"\u003cp\u003eThe 6600-168 is the replacement hi-limit sensor used on many Sundance® Spas and select Jacuzzi® hot tubs. It is a 2-wire electronic sensor with a 22-inch cable, a 1\/4-inch bulb and box-end connectors, and it ships with heat-shrink tubing. The hi-limit sensor is the safety partner to your spa's water temperature sensor: it watches the temperature at the heater, and if the water gets hotter than the control's preset limit, the control shuts the heater down. A failed or damaged hi-limit sensor can leave the heater locked out, cause overheat or hi-limit error messages on the topside, or stop the spa from heating at all.\u003c\/p\u003e\n\u003cp\u003eDealer fitment references list this sensor for Sundance® 650, 850 and 880™ series spas from 1995–2005 that use a bypass heater, 2006 and newer Sundance® 880™ systems, and older Sundance® 400, 600, 600S and 750 models with bypass heaters. On the Jacuzzi® side, it is listed for 2002+ J-300™ LCD systems, 2002–2003 J-350, J-360, J-370 and J-380 models, 2004–2006 J-355, J-365, J-375 and J-385 models, and 2006–2009 J-400™ models. It is also cataloged under 59-455-1204 and 6600-168-JC. Sundance® and Jacuzzi® have used several sensor plug styles over the years, so compare the box-end plug and short 22-inch cable on your old sensor before ordering; the 12 ft 6600-167 is the matching box-end water temperature sensor, not a hi-limit.\u003c\/p\u003e\n\u003cp\u003eTo replace it, turn off power at the breaker, note how the old sensor is routed, slide the new bulb fully into the same heater sensor well, and plug the box-end connector into the same position on the control board. One dealer notes that the current bulb can be slightly slimmer than some original sensors, so make sure it sits snugly in the well as your spa's service manual directs. If you aren't comfortable working inside the equipment bay, have a qualified spa technician do the installation.\u003c\/p\u003e","brand":"Sundance Spas","offers":[{"title":"Default Title","offer_id":53766893306168,"sku":"6600-168","price":71.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/1570\/3864\/files\/6600-168hisensor.png?v=1794252210","url":"https:\/\/www.hottubthings.com\/es\/products\/sundance-jacuzzi-hi-limit-sensor-6600-168","provider":"Hot Tub Things","version":"1.0","type":"link"}
