Water Heater Control Boards

Water heater control boards are the core electronic circuit boards inside electric water heaters that manage and regulate the heating process. They control essential functions such as temperature regulation, heating element activation, safety protections, user interface operation, and fault detection.

Choig offers a comprehensive range of water heater control boards designed for electric, gas, and tankless systems. Our control boards are essential components responsible for managing ignition, temperature regulation, and safety features in water heaters. With support for top heater brands and OEM or universal compatibility, Choig ensures reliable replacements backed by precision engineering and strict quality control standards.

How to Resolve Control Board Issues

1. 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.

2. 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.

3. 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.

4. Update or Reflash Firmware
   For advanced models, updating the control board firmware may resolve software glitches.

5. 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.
