Ensure the heater is cool and gas supply is shut off. Remove the access panel and locate the existing transformer. Unwire the primary (line side) and secondary (control side) leads. Install the R0456300 in the same mounting position, connect primary leads according to heater wiring diagram, and connect the secondary leads to the control board. Replace the access panel and restore power, then test heater operation to verify ignition and control circuit are functioning correctly.\u003c\/p\u003e\n\u003ch2\u003eMaintenance Tip\u003c\/h2\u003e\n\u003cp\u003eInclude transformer checks in annual heater service. Look for loose connections, discoloration around terminals or overheating signs. Replacing the transformer early on restores proper control circuit voltage, prevents ignition failures and helps maintain safe, efficient heater operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Jandy","offers":[{"title":"Default Title","offer_id":46797759053999,"sku":"R0456300","price":117.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/jandy-jxi-pool-heater-transformer-r0456300-heater-parts-2341148.jpg?v=1777066901","url":"https:\/\/freshized.com\/products\/jandyjxipoolheatertransformerr0456300jndr0456300","provider":"Freshized","version":"1.0","type":"link"}
