Perform a Visual Inspection
Check the control board for any visible signs of damage such as burnt components, corrosion, or loose connections. Ensure all wiring is securely attached.
Reset the System
Sometimes a simple reset can clear temporary errors. Turn off power to the heater for several minutes, then power it back on.
Check Related Components
Faulty sensors, wiring, or power supply issues can mimic control board failure. Verify the condition of temperature sensors, flow switches, and electrical inputs.
Update or Reflash Firmware
For advanced models, updating the control board firmware may resolve software glitches.
Replace the Control Board
If problems persist after troubleshooting, replace the control board with an original Choig replacement to restore proper operation and ensure compatibility.

Since the United States upgraded its tariff policy on China in 2024, the global manufacturing supply chain has been undergoing a deep adjustment. Labor-intensive industries represented by power tools, auto parts, and consumer electronics have accelerated their migration to low-cost regions such as Southeast Asia, Mexico, and Eastern Europe. It is worth noting that the "reciprocal tariff" policy implemented by the United States in April 2025 further changed the migration logic: Southeast Asian countries such as Vietnam and Thailand face high tariffs of 46% and 36%, forcing companies to shift their production capacity to regions with lower tax rates such as Africa and Latin America.
