That signal powers or supports the safety circuit on millivolt-style commercial fryer controls. Unlike a powered electronic control, a thermopile system depends on flame heat to generate enough voltage to hold the gas safety valve open and allow the fryer to continue operating.\u003c\/p\u003e\n\u003cp\u003eIn a Pitco fryer, the pilot flame heats the thermopile junction. The thermopile produces millivolts, and that output is used by the gas valve and safety circuit. If the flame is weak, the thermopile is dirty, the tip is not positioned correctly, or the thermopile is failing internally, the valve may not receive enough signal to stay open. The operator sees a pilot that lights but drops out, or a fryer that cannot bring on the main burner.\u003c\/p\u003e\n\u003ch3\u003eFailure Symptoms Technicians See\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePilot flame lights but goes out when the safety knob is released.\u003c\/li\u003e\n\u003cli\u003eMillivolt output is below the range needed to hold the gas valve.\u003c\/li\u003e\n\u003cli\u003eFryer pilot stays lit cold, then drops out after vibration or heat cycling.\u003c\/li\u003e\n\u003cli\u003eMain burner will not energize because the safety circuit is not satisfied.\u003c\/li\u003e\n\u003cli\u003eThermopile tip is carboned, corroded, or not fully engulfed by flame.\u003c\/li\u003e\n\u003cli\u003eLoose safety-valve terminals reduce millivolt signal under load.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDiagnostic Approach\u003c\/h3\u003e\n\u003cp\u003eTechnicians diagnose a thermopile by measuring open-circuit and loaded millivolt output while the pilot flame is properly adjusted. The pilot flame should be blue, stable, and wrapped around the sensing tip. Related components include the pilot burner, pilot orifice, gas safety valve, high-limit circuit, thermostat, and wiring terminals. If the flame is correct but millivolt output remains low, replacing the thermopile is appropriate.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does Pitco 60125501 do?\u003c\/strong\u003e\u003cbr\u003eIt generates a millivolt signal from pilot flame heat for the fryer safety\/gas-control circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy will the pilot not stay lit?\u003c\/strong\u003e\u003cbr\u003eThe thermopile may be weak, but pilot flame quality, gas valve condition, and connections must also be checked.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is it tested?\u003c\/strong\u003e\u003cbr\u003eWith a meter reading millivolts, both unloaded and under the safety-circuit load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat related parts should be inspected?\u003c\/strong\u003e\u003cbr\u003ePilot burner, pilot orifice, gas safety valve, high-limit, thermostat, and terminal connections.\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\/pitco-parts\"\u003ebrand replacement parts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pitco","offers":[{"title":"Default Title","offer_id":50105513279711,"sku":"60125501","price":105.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3047\/0623\/files\/pitco-60125501-thermopile-millivolt-oem-replacement-part-partsdirectonline-2529073.webp?v=1782194285","url":"https:\/\/partsdirectonline.com\/products\/pitco-60125501-thermopile-millivolt","provider":"PartsDirectonline","version":"1.0","type":"link"}
