✓NOTE : If the product is connected but not working (e.g., non-functional igniter switch, no igniter voltage/spark, or circuit board issues), this is mainly due to poor contact between the product’s card connector and the water heater slot. To fix it: 1. Clean the water heater slot with a brush to remove dust. 2. Clean the card connector of the control board with a dry cloth, eraser, or a little alcohol—tin-plated contacts oxidize easily, causing poor connection. Do NOT use a wet cloth or let this area get wet. 3. After cleaning, align the card connector with the slot perfectly during reinstallation; slight misalignment causes poor contact. Following these steps will resolve the issue.
✓Easy Installaion: Please refer to the note first. The Water Heater Circuit Board adopts the design of plug-and-play concept with standardized interfaces and connectors, making the installation process easy.Even without the professional personnel, the whole replacement process can be completed just within few minutes.
✓After-sales service: If there is any problem with the product, please feel free to contact us, We will try our best to provide you a satisfactory shopping experience.
✓Attention: Please check that the interface is properly connected during installation. If the device doesnt work, the issue may be poor contact caused by dirt in the card slot, or the card not being inserted and connected correctly in the slot.
