1kw or 1000w 20 1200w. Look at the resistor so the group of 3 or 4 color bands are on the left side.

The resistor value would have been sufficient to reduce current flow to a value that could be safely conducted by the series device with the lowest allowable current value.

How to know resistor. The resistor of the blower motor is responsible for transferring the electrical current thats required to move air through the vents of vehicle. Standard resistors have four color bands. Find the resistor outline on the chart that most closely matches that of the resistor itself.

Blower motor resistors can wear out. How to identify resistors color coded resistors axial resistors axial resistors are cylindrical with leads extending from each end. For example a 1kw 20 tolerance resistor may have a maximum and minimum resistive value of.

Four of the. There are several symptoms that appear when the resistor of the blower motor is going bad. You can determine a resistors wattage with a size chart.

Precision resistors which have more precise values than standard resistors have five color bands. Place the size chart see reference on a flat surface. The wreath circuit is most likely wired in series if it contained a resistor.

Read the color bands from left to right. Three of the bands tell you the nominal value which means the value the resistor was designed to have. Read the color on the last color band.

In series circuits total current is felt across each load device in the circuit. The power rating of a resistor is decided by the manufacturer and stated by them. Skin temperature rise resistor value change terminal wire temperature rise etc.

The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. Using ohms law to help with selecting the resistor value for led circuits. The blower motor no longer works correctly if this occurs.

There are two main types of resistors. There are online calculators and apps but i think knowing how to calculate it yo. They will determine what the end point is that the specification achieves.

Place the resistor on the outline to make sure they match.
