It may work in several different ways, depending on the actual circuit used. As asked no better answer can be given than the circuit board alternately turns the current in the LED on and off.

A circuit board consists of numerous electronic components, depending on the application, these components can be in the thousands or in the ten's, therefore circuit boards vary in numerous sizes, all connected using very fine electrical connection strands.
Sure. If you want sound when the circuit is energized, use a buzzer. If you want a visual indication when the circuit is energized, use an LED.

LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.
The cause of a LED light flashing intermittently could be a loose connection, a faulty power supply, or a problem with the LED driver circuit.

The conclusion of the report on a classic astable multivibrator circuit or LED flasher circuit using 2 transistors could summarize the key findings and performance of the circuit. This may include discussing the frequency of the flashing, power consumption, stability of the circuit, and any modifications made to improve its function. Additionally, the conclusion could also highlight practical applications, limitations, and potential areas for future experimentation or enhancements.
In most cases the lights are in your odometer. There is an LED bulb behind each symbol and the LED is lit up because it is sitting on a circuit board. The circuit board gets its power from the car battery through a series of wiring and relays.

The LED lights are flashing on and off because they are designed to do so as a part of their normal operation.
No, no parts of cell phones or mobile phones are made of iron. The metals used in these phones are:Aluminium (covers, frames, battery, circuit board.)Antimony (covers)Barium (circuit board)Beryllium (connectors)Cobalt (lithium-ion batteries)Copper (circuit boards, wires, connectors, batteries)Chromium (cover, case)Gallium (LED light)Gold (electronic parts, connectors, circuit board)Indium (screen)Lead (circuit board)Manganese (circuit board, case)Nickel (battery)Palladium (circuit board)Platinum (circuit board)Ruthenium (circuit board)Silver (circuit board)Iron is heavy, gets warm quickly and reacts with moisture in the air leading to rust, so iron is not a suitable metal for a phone.
The flashing LED code should be somewhere, either in the Installation/Operation manual or on the wiring diagram which should be on one of the unit`s cabinet covers or the code maybe right on the circuit board in small type. If not Google the make & model # of your furnace. Or call a service tech.
