Installation a diode or resistor

In the case of electrical noise, a resistor or diode can be installed in the affected components. A diode is often used, but it must not be too large, otherwise interference may occur. DC Diode: FR307, white = minus, black = plug ; AC Diode: RG009 = AC, ring = minus, rectangle = plus

The diode or electrical resistor is installed directly on the pin of the chip adapter of the WiFi module: Burner D4, Cooling D18, Agitator D21, Lamp D23.

If the digital servo (airflow damper) constantly makes small movements, a diode or electrical resistor can be installed on the red cable.
