The resistor pack is a very simple device which allows multiple fan speed settings from the same nominal 12V input. It has three 12V inputs and a single output, which is the motor feed. ... The majority of failures are with the electrical crimp connections on the resistor pack and not the internals of the pack itself.

What is resistor kit?
It comes with a box that allows you to easily store the resistors. ... A major benefit of the Resistor Assortment Kit is that it includes all commonly used resistance values. Having the resistor kit on hand will ensure that needed resistors are readily available when constructing and testing your electronic circuit.
How much does a resistor cost?
A blower motor resistor costs anywhere between $1 and $400.
Which resistor should I buy?
A rule of thumb is to find a resistor with twice the power rating. Here I would choose a 250 mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.
What is metal film resistor?
Metal film resistors have a thin metal layer as resistive element on a non-conducting body. They are among the most common types of axial resistors. ... The appearance of metal film resistors is similar to carbon film resistors, but their properties for stability, accuracy, and reliability are considerably better.
How do you buy resistors?
When choosing a resistor to buy for a given application calculate the power dissipation and run it well within its ratings. Many companies that design electronic equipment recommend running them at a maximum of 50 or 60% of their maximum rating.
Why does car AC only work on high?
The blower motor powers the fan that allows hot or cold air to flow from the vents in your vehicle. It is the life of your HVAC system. ... The blower motor resistor is prone to shorts, corrosion, and overheating. When the resistor fails, typically, the highest setting is the only option that still functions.
What is the most common resistor?
The E3 series resistors are the most widely used and hence these values will be the most common resistor values used within the electronics industry.
How do you know what resistor to buy?
Determine the resistance and the watts to be dissipated by the resistor. Determine the proper "Watt Size" (physical size) as controlled by watts, volts, permissible temperatures, mounting conditions and circuit conditions. Choose the most suitable kind of unit, including type, terminals and mounting.
What resistor do I need to reduce voltage?
To reduce voltage in half, we simply form a voltage divider circuit between 2 resistors of equal value (for example, 2 10KΩ) resistors. To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors.
What is the advantage of a metal film resistor?
Advantages of metal film resistor:
Long term stability. Low tolerance. Low temperature coefficient of resistance hence the resistance of the metal film resistors does not change easily with change in temperature. Very small in size.
Where is metal film resistor used?
Applications of metal film resistors
They are used when a high tolerance or more accurate value is needed in a circuit. They are also used for bridge circuits, filter circuits, and low-noise analog signal circuits. Metal film resistors are not suitable for applications that expose them to surge transients.
What is a ceramic resistor?
Ceramic resistors are manufactured from a sintered body of ceramic material, with conductive particles distributed throughout the matrix, to produce a resistor that is 100% active and non-inductive. Ceramic resistors are chemically inert.
