Gas Dryer Troubleshooting

This is an universal style coil kit, it will fit MANY different brands and makes!

Change the coils in pairs of two, they are cheap and an easy repair, so doing both at the same time is a safer repair.

An Volt/OHM meter is the tool needed for ohming the dryers gas valve coils or for testing voltage.

You can test the coils using a multi-meter. The two prong coil ( 4 and 5 ) will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1 and 2, and 500-600 ohms across prongs 1 and 3.

Before testing the gas coils, unplug the clothes dryer or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard. Turn off the gas line to avoid a possible gas leak. When moving a gas dryer be careful not to damage the gas line.

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.

One easy way to diagnose a problem in the burner assembly is to observe the burner operation. Remove the small access panel at the bottom front of the dryer (many newer dryers no longer have this feature so you may be able to see and listen to the gas valve and ignitor with the top panel removed), select a high temperature setting and start the appliance. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow. Next you should hear the click of the gas valve coil and a flame should ignite. The flame should be mostly blue and it should remain on for a minute or more.

If the ignitor glows for several seconds (up to 15 seconds) and then goes out, the problem is probably the coils (solenoids). If the ignitor glows and stays on, then the problem is usually the flame sensor. If it ignites and then quickly goes out, it is most likely a problem with inadequate air flow.

Not sure why, but someone decided to mould the two separate coils all together into a coil block...and there are 2 versions.

I found no different way to test them, so they should ohm test like mentioned above.

Not sure why, but someone decided to not make the coils a separate part and if you have any issues with the gas valve coil, you must replace the whole gas valve assembly.

Not smart LG!
