It is responsible for the high-voltage spark output and the flame-proving logic that determines whether the burner can remain on. In a gas oven, the ignition module acts as the coordinator between the heat call, spark electrode, gas valve, and flame signal.\u003c\/p\u003e\n\u003cp\u003eWhen the oven calls for heat, the module starts an ignition trial. It sends spark to the electrode and coordinates gas valve operation according to the oven safety sequence. Once the burner lights, the module must sense flame through the flame-rectification path. If it does not detect flame, it interrupts the burner operation to prevent unsafe gas flow. That means a weak ground, dirty flame rod, poor burner flame, or damaged wire can cause the same symptoms as a failed module.\u003c\/p\u003e\n\u003ch3\u003eFailure Symptoms Technicians See\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIgniter does not spark during startup.\u003c\/li\u003e\n\u003cli\u003eSpark is present, burner lights, then shuts off after a few seconds.\u003c\/li\u003e\n\u003cli\u003eModule locks out during trial for ignition.\u003c\/li\u003e\n\u003cli\u003eIntermittent heat loss after vibration or heat expansion.\u003c\/li\u003e\n\u003cli\u003eGas valve output is missing even though the thermostat is calling.\u003c\/li\u003e\n\u003cli\u003eFlame signal is unstable because of grounding or electrode contamination.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDiagnostic Approach\u003c\/h3\u003e\n\u003cp\u003eA technician should measure input voltage to the module, verify ground integrity, inspect the spark electrode and wire, check gas valve output, and clean the burner\/flame-sensing area. Flame rectification depends on a clean flame path and solid ground. If all inputs are correct and the module will not generate spark, will not energize output, or will not recognize flame, the 54388 module is a likely cause.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the Blodgett 54388 module do?\u003c\/strong\u003e\u003cbr\u003eIt produces spark and monitors flame signal in the commercial oven ignition sequence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the oven spark but not stay lit?\u003c\/strong\u003e\u003cbr\u003eThe module may not be reading flame, or the flame-sense electrode, ground, burner, or wiring may be faulty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Fenwal HV100G reference?\u003c\/strong\u003e\u003cbr\u003eIt identifies the ignition module style associated with this Blodgett part number.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat related components should be inspected?\u003c\/strong\u003e\u003cbr\u003eSpark electrode, flame sensor, gas valve, burner, ground path, thermostat call, and wiring harness.\u003c\/p\u003e\n\n\u003ch3\u003eRelated resources\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/middleby-oem-replacement-parts\"\u003erelated commercial equipment parts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/contact\"\u003econtact fitment support\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/blodgett-parts\"\u003ebrand replacement parts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Blodgett","offers":[{"title":"Default Title","offer_id":50105025659103,"sku":"54388","price":390.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3047\/0623\/files\/blodgett-54388-ignition-module-fenwal-hv100g-oem-replacement-part-partsdirectonline-6028868.jpg?v=1782194291","url":"https:\/\/partsdirectonline.com\/products\/blodgett-54388-ignition-module-fenwal-hv100g","provider":"PartsDirectonline","version":"1.0","type":"link"}
