Sounds like the coils on the gas valve itself done by the igniter. When they get weak they can only hold the gas valve open for a short time. If you leave it long enough does the igniter come on but the gas not light? That is a sure sign the coils are weak. Sometimes they will even make a clicking sound as they try to open. They are pretty cheap and nearly all dryers use the same coils. They are little black cylinders mounted on top of the valve. Let me know that doesn't make sense.

Dryer does not heat constantly. It starts to heat then turns off the gas. I need to dissamble it to test the parts.

Sounds like a block in the exhaust. Remove exhaust pipe and clean pipe. This is a huge fire hazard and your dryer is likely saving you from a fire. Remove large back panel on dryer. Clean all passages that handle airflow from lint screen back to exhaust. Restart. If this does not work, be happy that it is now clean :) The issue is likely your flame sensor at this point. Looks a bit like a spark plug. Short term fix. Clean probe with a dollar bill. Seriously, a dollar bill. Replace and restart. Order a new flame sensor.

Heat level in dryer

A dryer usually overheats because of a kink or blockage in the duct work, blockage in the outside wall cap, or because of a defective cycling thermostat. The cycling thermostat tells the dryer when to heat and not to heat. Clean any lint from the inner and outer ductwork. You can also remove the vent from the back of the dryer for a load or two to determine if the clothes dry faster or not. If this doesn't fix it, go ahead and replace the cycling thermostat. Make sure to use the appropriate setting to dry the clothes.

air flow. you must make sure that your dryer vent hoses are free of lint. if you found a lot of lint in the bulkhead more than likely your vents are cloged

Lg dlg7188rm - My dryer is not getting hot. When I start a cycle the ignitor comes on (orange glow under dryer) and then gas comes on (blue glow). After about 30 seconds both shut off.

There are two or three sensors in the heat exchanger and another one or two in the fan housing. Check them all for continuity. One in the heat exchanger is resettable

LG DLG0452W: Light inside the drum stays on even after closing the door tightly and dryer does not start. It flashes to check the lint tray but there isn't anything in there. HELP!!

If that light stays on I would say something definitely is wrong with the door safety lock mechanism. I have an LG dryer service manual that may help you: LG GAS& ELECTRIC DRYER repair manual

If your dryer is not drying like it once did or if you just have nottaken the time to give yourself a clean dryer in a long time then youneed to do that. At least once a year the dryer cleaning should takeplace. Lint build up in the dryer duct is one of the main causesfor your dryer to fail.
