The bumps are usually accompanied by redness and swelling. Allergic eczema is an allergic skin reaction that produces an itchy, red skin rash. The rash may consist of raised, red bumps that ooze, drain, or crust. Angiomas are common skin growths that can form on most areas of the body.
Blower resistors are resistors which are used to control the fan speed of automotive blowers. 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.
Contributed by: FRIEDELECTRICIAN. You cannot use a light dimmer to control a fan. There is a growing misconception that this is safe to do, but the logic behind it is flawed. Let me explain: A fan that has no speed control when manufactured has copper windings inside that determine speed and horsepower.
