A dryer’s heating element operates on the same principle as the coil in an electric heater. It consists of an uninsulated metal conductor and when an electric current passes through it, its resistance to the flow of electricity makes it heat up. If the coil gets too hot, it burns out.

What does a dryer coil do?

A gas dryer blows air through a burner assembly to heat the air. … On the gas valve are one or two coils (solenoids) used to open and close the valve to control the flow of gas. If a coil fails, gas will not flow and the dryer will have no heat.

How do I know if my gas dryer coil is bad?

Locate the gas valve and remove the coil(s) and test them using a multimeter, if you get a resistance reading on the meter of 1000-2000 ohms, the coil is bad and must be replaced.
