1. Safety First

Before you start, always ensure safety. Turn off the heater and disconnect it from the power supply. This prevents any electrical accidents, keeping you safe as you work.

2. Inspect the Control Board

Open the control panel of your heater. Look for any signs of damage, such as burnt areas, corrosion, or broken components. If you find anything unusual, it might be time to replace the control board.
