Quick Tips

Gas flame comes on first few times then quits and ignitor keeps cycling on and off but never lets the gas go.
Replace the coils on the Gas Valve.

No flame, no ignitor at all,
Inspect ignitor for small burnt spot on dark gray or black part of ignitor or check for 110 volts to ignitor when dryer should be calling for heat, or check for continuity with ohm meter.

Product Damage

? The ignitor at the end of the burner is very fragile.

? Do not hit or bump this.

? Handle with care.

Failure to do so could result in product damage.

Dryer takes too long to dry or multiple times to dry a load
Pull the dryer out away from the wall. Unhook the vent from the dryer completely. Do not put anything over the dryer exhaust on the back of the dryer. Do a normal load with the vent unhooked. If it dries better or ok like this then the problem is in the dryer venting. Like a blocked vent pipe or a smashed or restricted vent hose.

If the vent  doesn't make a difference, then check the blower wheel for excessive lint build up, check that there isn't anything stuck to the air intake baffle inside the drum, (i.e. the screen on the back wall of the dryer when looking into the drum). Check the lint filter chute for blockage. Check that the heating element isn't shorted to ground. Check the exhaust temperature of the dryer. A meat or pocket  thermometer can be used for this. It should cycle between 120 degrees and 180 degrees. Check that the rear drum seal isn't worn out.
