  • The 520820 12V DC RV furnace ignition control module board is built with high-quality materials. The electronic waterproof coating provides corrosion resistance, waterproofing, and dust-proof performance, ensuring durability and long-term reliability. Designed to operate under various environmental conditions, this 520820 control board guarantees stable and lasting performance for your RV module. It is the perfect replacement choice for your furnace circuit board.
  • Note: If the product is connected but not working, the cause is most likely poor contact between the card connector and the water heater slot. To fix it, first clean the water heater slot with a brush to remove dust, then clean the card connector on the control board using a dry cloth, eraser, or a small amount of alcohol, as tin-plated contacts oxidize easily and cause poor connection; do not use a wet cloth or allow this area to get wet. After cleaning, make sure the card connector is perfectly aligned with the slot during reinstallation, as even a slight misalignment may lead to poor contact.
  • To save yourself some hassle, please take a picture of the old one before removing it, make sure getting the wires on the correct terminals. Please feel free to contact us if you have any questions about our products, your satisfaction would be our greatest motivation.
