Wacker Neuson designates relays in this position as K1 and K2, and the official service manual specifies a coil resistance of 825 to 1025 ohms across terminals 0 and 1. Normally closed contacts should measure approximately 0.1 ohms across terminals 3 and 4, and normally open contacts should measure approximately 0.1 ohms across terminals 2 and 4.\u003c\/p\u003e\n\n\u003cp\u003eThe manual outlines a step-by-step testing procedure performed with a multimeter after placing circuit breaker 1 and circuit breaker 2 in the OFF position. Any resistance reading outside the specified coil range, or a failed continuity check across either contact set, indicates the relay has failed and must be replaced. Working inside the control panel requires extreme care due to the high-voltage hazard present even when circuit breakers are off.\u003c\/p\u003e\n\n\u003cp\u003eReplace this relay when diagnostics confirm an out-of-spec coil resistance or an open or shorted contact, which can cause circulation pump or heating element control faults on the E3000 6kW hydronic ground heater.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWacker Neuson E3000\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398700302384,"sku":"WACKER-5100028015","price":57.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100028015.jpg?v=1784070878","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-30a-120vac-power-relay-5100028015-for-e3000-heater","provider":"CCE Industries","version":"1.0","type":"link"}
