This thermistor-based switch measures temperature changes and provides accurate input to the vehicle’s electronic control system, supporting proper climate control operation and system protection in fleet and vocational environments.\u003c\/p\u003e\n\u003cp data-start=\"465\" data-end=\"947\"\u003eThermistor temperature switches play a critical role in monitoring temperature conditions within HVAC or related systems by providing precise resistance-based feedback as temperatures change. As original thermistor switches wear, drift out of calibration, or fail electrically, inaccurate readings and reduced system efficiency can occur. Replacing worn thermistor switches helps restore accurate temperature sensing, improve system reliability, and reduce unplanned service events.\u003c\/p\u003e\n\u003cp data-start=\"949\" data-end=\"1359\"\u003eKEY FEATURES\u003cbr data-start=\"961\" data-end=\"964\"\u003e• Designed for heavy-duty truck HVAC and temperature monitoring applications\u003cbr data-start=\"1040\" data-end=\"1043\"\u003e• Thermistor-based switch provides accurate temperature feedback to control systems\u003cbr data-start=\"1126\" data-end=\"1129\"\u003e• Supports reliable climate control operation and system protection\u003cbr data-start=\"1196\" data-end=\"1199\"\u003e• Durable construction suited for fleet, vocational, and on-highway use\u003cbr data-start=\"1270\" data-end=\"1273\"\u003e• Brand: Volvo\u003cbr data-start=\"1287\" data-end=\"1290\"\u003e• Verify compatibility and application requirements before ordering\u003c\/p\u003e\n\u003cp data-start=\"1361\" data-end=\"1585\"\u003eTECHNICAL SPECIFICATIONS\u003cbr data-start=\"1385\" data-end=\"1388\"\u003eAlltrux Part Number: ATX938-1042\u003cbr data-start=\"1420\" data-end=\"1423\"\u003eOEM Reference: 20478470\u003cbr data-start=\"1446\" data-end=\"1449\"\u003eProduct Type: Thermistor Temperature Switch\u003cbr data-start=\"1492\" data-end=\"1495\"\u003eBrand: Volvo\u003cbr data-start=\"1507\" data-end=\"1510\"\u003eSystem Application: Heavy-Duty Truck HVAC \u0026amp; Temperature Monitoring System\u003c\/p\u003e\n\u003cp data-start=\"1587\" data-end=\"1616\"\u003eCROSS REFERENCES\u003cbr data-start=\"1603\" data-end=\"1606\"\u003e20478470\u003c\/p\u003e\n\u003cp data-start=\"1618\" data-end=\"1755\"\u003eNote: Confirm OEM reference and application details before ordering to ensure proper fit and temperature monitoring system compatibility.\u003c\/p\u003e","brand":"JX Peterbilt","offers":[{"title":"Default Title","offer_id":44154354696372,"sku":"ATX938-1042","price":42.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/11-1642__40928__61339.jpg?v=1772483804","url":"https:\/\/parts.rodoc.com\/products\/atx938-1042-switch","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
