It is the module that runs the heater from a call for heat to a lit burner.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it controls\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOn a call for heat the ignition control drives the igniter, opens gas at the right point in the sequence and watches for proof of flame. If it does not see what it expects, it shuts the sequence down rather than keep gas flowing. That is why a failed control shows up as a heater that goes through the motions and never lights, or one that lights and then drops out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSeveral other faults produce the same symptom, including gas supply, the igniter, the flame sensor and the safety switches. Have the sequence diagnosed properly first. Ignition parts sit on the gas train of a fired appliance, so the work belongs to a qualified technician.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48633453805780,"sku":"LAR-151-1237","price":172.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_958aec07-164a-4531-bd73-87dddfdb9661.jpg?v=1788804948","url":"https:\/\/www.activepoolsupply.com\/products\/ignition-control","provider":"Active Pool Supply","version":"1.0","type":"link"}
