A ceramic element draws current and glows to ignition temperature, and the gas valve opens onto the already-glowing element to light the main burner. That matters for diagnosis: you will not hear clicking from a hot surface system, so a silent no-light is normal behaviour for a failed igniter rather than a sign of a different fault.\u003c\/p\u003e\n\u003ch2\u003eWhen This Is the Part You Need\u003c\/h2\u003e\n\u003cp\u003eThe classic symptom is a heater that responds to a call for heat, runs its blower and purge cycle, and then locks out without ever lighting. A failed igniter often looks visibly cracked, blistered or dull where it should be intact. Ignition-failure and lockout codes that clear on reset and then return point the same way.\u003c\/p\u003e\n\u003ch2\u003eCompatible Heaters\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLaars \/ Jandy \u003cstrong\u003eLite2 model LJ\u003c\/strong\u003e, built before 2006\u003c\/li\u003e\n\u003cli\u003eCovers the full size range: \u003cstrong\u003eLJ125, LJ175, LJ250, LJ325, LJ400\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncludes the natural gas variants, for example LJ250N\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Jandy OEM:\u003c\/strong\u003e factory part for the Lite2 LJ burner, not an aftermarket equivalent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting screw included:\u003c\/strong\u003e no separate hardware order.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCovers the whole LJ range:\u003c\/strong\u003e one igniter serves LJ125 through LJ400.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagram item 31:\u003c\/strong\u003e matches the Lite2 LJ service documentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso sold as Laars:\u003c\/strong\u003e the same part appears under the Laars and Teledyne Laars names.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e R0367100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Hot surface igniter replacement kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimensions:\u003c\/strong\u003e 4.75 in L x 1.25 in W x 0.75 in D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Length:\u003c\/strong\u003e 4 in, bracket to tip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Material:\u003c\/strong\u003e Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Igniter with bracket and mounting screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagram Reference:\u003c\/strong\u003e Item 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost-2006 Equivalent:\u003c\/strong\u003e R0449800 igniter box assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlternate Part Numbers:\u003c\/strong\u003e 47-295-2524, LAR-151-3671, J2017, W00425, Model 601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Jandy \/ Zodiac, Laars lineage (Genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eHow do I know if my heater is pre-2006?\u003c\/h3\u003e\n\u003cp\u003eCheck the date of manufacture on the rating plate, usually on the side of the cabinet or inside the front panel. The serial number also encodes the build date. If you are unsure, send us the serial number and we will tell you which igniter you need.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between this and R0449800?\u003c\/h3\u003e\n\u003cp\u003eR0367100 is the igniter itself for pre-2006 heaters. R0449800 is the igniter box assembly used on heaters built from 2006 onward. They occupy the same position on the parts diagram but are built differently and cost differently.\u003c\/p\u003e\n\u003ch3\u003eWhy does my heater run but never light?\u003c\/h3\u003e\n\u003cp\u003eA failed igniter is the most common cause. The control board runs its normal pre-purge, calls for ignition, gets no flame signal and locks out. Before replacing it, confirm gas supply and that the gas valve is opening, since those produce the same symptom.\u003c\/p\u003e\n\u003ch3\u003eCan I test the old igniter?\u003c\/h3\u003e\n\u003cp\u003eA resistance check across the element will show an open circuit on a failed unit. A visual inspection is often enough — cracks, blistering or a chalky, eroded element all mean replacement. Never test by touching the element.\u003c\/p\u003e\n\u003ch3\u003eHow careful do I need to be installing it?\u003c\/h3\u003e\n\u003cp\u003eVery. The ceramic element is brittle and a hairline crack from handling will kill it immediately, producing exactly the fault you were trying to fix. Handle the igniter by its metal base and bracket only, never by the element.\u003c\/p\u003e\n\u003ch3\u003eIs this the same as the aftermarket igniters sold for these heaters?\u003c\/h3\u003e\n\u003cp\u003eNo. Several manufacturers sell aftermarket igniters marketed against the Lite2 LJ. This listing is the genuine Jandy OEM part.\u003c\/p\u003e\n\u003ch3\u003eWho should install it?\u003c\/h3\u003e\n\u003cp\u003eA qualified pool professional or licensed gas technician. The heater must be isolated at the breaker and the gas supply shut off before the burner tray is accessed.\u003c\/p\u003e\n\u003cdiv class=\"ps4u-faq\"\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the part number for this igniter?\u003c\/h3\u003e\n\u003cp\u003eJandy lists this igniter under part number R0367100. Quote R0367100 when you cross-reference it against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.\u003c\/p\u003e\n\u003ch3\u003eHow do I confirm this fits my equipment?\u003c\/h3\u003e\n\u003cp\u003eMatch the part number on the component you are replacing, or look it up in the parts list for your Laars or Jandy heater. Build year matters on this part, so if your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.\u003c\/p\u003e\n\u003ch3\u003eDoes gas heater work need a professional?\u003c\/h3\u003e\n\u003cp\u003eYes. Gas heating equipment sits under specific code requirements covering gas supply, venting, bonding and grounding. Shut off the gas and cut power at the breaker before opening the heater, and have a licensed professional carry out the work.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty on this part?\u003c\/h3\u003e\n\u003cp\u003eIt carries the standard Jandy manufacturer warranty. The terms are set by Jandy, and on gas heating equipment the coverage generally applies only when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003csmall\u003eCalifornia Proposition 65 Warning: This product can expose you to chemicals known to the State of California to cause cancer and reproductive harm.
