☑ How Does A Heater Resistor Work

If no power is observed then the control head is bad. Devices called resistors let us introduce precisely controlled amounts of resistance into electrical circuits.

Blower Motor Resistor How It Works Symptoms Problems

Four typical resistors sitting side by side in an electronic circuit.

How does a heater resistor work. Locate the fuse for the blower motor in the ownersservice manual. In some cars a failed blower motor resistor can cause a heater fan to stop working completely. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting.

Test the fuse with the ignition key on using the 12 volt test light. If there is power the motor is bad. Heater blower resistor has to be replaced.

The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. In most cases a blower motor resistor fails due to corrosion or overheating. Lets take a closer look at what they are and how they work.

What is a resistor and how does it work. If there is no power check the resistor for power. If there is power the resistor is bad.

Attach the clip lead of the test light to a good ground like a bolt screwed into metal and touch the sharp probe end to the terminals on the fuse. The most common symptom of a failed blower motor resistor is when the heater fan only runs at the highest speed setting 4 or 5 and doesnt work at low speeds. The easiest way to check for a failure is to start the vehicle and turn the climate control on.

The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever or electronically by the air conditioning system. You have to remove glove boxthe resistor is to the right of the heater blower moter. In this video i will show you how a common induction heater works what kind of materials it can heat up and how you can easily create your own.

Check the blower motor at its two wire connector for power. Blower resistors are resistors which are used to control the fan speed of automotive blowers. The heater blower motor reduces or increases the amount of air blowing through the dashboard vents based on the fan speed selected or in an automatic climate control system the interior.

A resistor works by converting electrical energy into heat which is dissipated into the air. 2011 lookalike by bartlebeats. If the resistor shorts or fails it may cause the blower motor to remain stuck on one fan speed.
