I have a five-color ring resistor, and the third ring is gold. Can you ask the great god to explain? The circuit board is on the humidifier, and the resistance is welded from the position of F 1(RX 2W) on the drawing. If the first coil is black, it is estimated to be a safety resistance of 0.2 ohm.

If the first circle is gray, it is estimated to be a safety resistance of 8.2 ohms.

The last red or other color is usually the manufacturer's logo, and I have indeed seen resistors with this manufacturer's logo. I used to be a component inspector.

For the replacement of safety resistors, it is best not to use ordinary resistors because the materials are different. It is better to use fuse tubes instead.
