This transformer steps down incoming line voltage to the 24V control signal that powers your thermostat, contactor coil, and low-voltage safety circuits. A failing transformer is one of the most common causes of a completely dead system, a tripped low-voltage fuse, or a thermostat with no display — replacing it restores full control operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRating: 40 VA\u003c\/li\u003e\n\u003cli\u003ePrimary voltage: 208\/240V\u003c\/li\u003e\n\u003cli\u003eSecondary voltage: 24V\u003c\/li\u003e\n\u003cli\u003eFoot-mount design for standard control-box installation\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement for APH1336H41CA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e transformer is the exact factory part with correct VA rating, mounting footprint, and lead configuration — no rewiring or adapters required. Aftermarket generics may carry a similar VA rating but often differ in mounting bracket, lead length, or terminal layout, leading to slower installs and potential control faults. For a control component that your entire system depends on, the OEM part is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — requires basic electrical knowledge. Always disconnect power at the breaker before servicing. Label and transfer the primary and secondary leads one at a time, verify the 24V output with a multimeter, and confirm proper operation before closing the panel. If you are not comfortable working with line-voltage wiring, we recommend a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058267996531,"sku":"GOODMAN-15245","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-40-va-24v-transformer-for-aph1336h41ca-0130m00138s","provider":"National HVAC Parts","version":"1.0","type":"link"}
