what purpose does th resistor have on dryer? pn we4m255 and do you get resistense on ohm meter?

Hello
The main function of the resistor in a circuit is to control the flow of current to other components. Take a light bulb for example. If too much current flows through the bulb it is destroyed. So a resistor is used to limit the current. The continuity test applies a very small voltage to the circuit and check what current flows through it. If the current is larger than the lower limit (for continuity test of your multi meter), it beeps. For example, you cannot have a beep testing a diode, because it has a voltage drop (about 0.6V). If you measure a resistor with less than 10 ohms, probably you will hear the beep. If you check your multi meter it will not be hard to specify the maximum resistance or voltage drop to make it beep.
