Gas Dryer Troubleshooting
Quick Gas Dryer Tips:
Problem -
Gas flame comes on first few times then quits and igniter keeps cycling on and off but never lets the gas go. Answer ( most common ) -
Replace the coils on the Gas Valve.
M Series Ignition Coil Set used on many Whirlpool/Kenmore brand gas clothes dryers since 1984. Comes with both the three terminal Boost/Hold and two terminal Secondary coil Problem -
No flame, no igniter glowing at all. Answer ( most common ) -
Inspect igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter when dryer should be calling for heat.
Silicone Carbide Igniter Kit with ceramic holder. Used on many Whirlpool/Kenmore brands gas clothes dryers Gas dryer with no heat:
The parts that I have pointed out with the arrows are the parts that you will need to check with an ohm meter if the dryer is not heating. First check and see if you have 110 volts coming to the gas valve at this type of a connector. If you have voltage, then unplug the dryer and check the parts I have pointed to. Some dryers have 3 coils instead of the 2 shown here. If you do not have voltage coming to the burner, then you will need to check the timer contacts that feed the gas burner, hi limit thermostat, operating thermostats, the safety switch on the motor, and any other point that you can see on your wiring diagram picture that feeds voltage to the burner. The coils on the gas valve are very bad for working once or twice and then quitting. If you find a open circuit on one of the gas coils, replace them all = less problems later on. If the glow coil does not work ( get red ), check it with a ohm meter for continuity. The next thing to check if the glow coil does not come on would be the radiant sensor. Inspect the igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter wire plug when dryer should be calling for heat. Sometimes the ( older style ) igniter is separate from the holder and the holder can no longer hold the igniter tight enough and the two parts burn/arc where they touch each other = new igniter and holder ( some manufactures have new kits to replace these older style parts ).
Does the igniter get red and stay red, or does it get red, you hear a click and it goes off, then a minute later its gets red again?....if so you possibly have a bad set of coil valves. If the igniter gets red and stays red constantly then its the flame switch that is bad and maybe welded closed.
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.
