most likely the gas coils. replace both coils, The other thing is be sure the vent is clear all the wayto outside.

Welcome crow33 to the Gas Appliances topic and the Do-It-Yourself Web Site.

First check the dryers venting system. If the vent is restricted and or plugged up anywhere, the dryer will over heat and the burner will shut down.

Many Additional Possible Causes: (Some May Or May not Apply)

Based on the fact that the dryer is heating but the dryers burner shuts down too soon, chances are the venting system is restricted. Very common problem when the condition you're describing happens. The test is to remove the entire vent from the dryer and dry a normal load of clothes.

If the same problem does not occur, the venting system is restricted. Cleaning and clearing the venting system is required. Do not forget to check the vent hoods flapper door. Flapper must be freely able to move.

If the same problem happens, the problem is elsewhere within the dryer. Best bet before attempting to replace parts, is to do the testing suggested above. It is the most common problem and least costly to resolve the problem.

Retail appliance parts dealers can also help determine what the most likely possible problem may be. They will need the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts and problem resolving matters. Dealers are listed in the phone book under appliances.

Be sure the electrical power to the appliance is turned off, before attempting any repairs or services. Always check for gas leaks whenever moving the appliance and/or a service or repair includes any connection of a gas part.

Read the existing questions on the subject of dryers. Doing so will more quickly provide you with answers to questions & provide additional information on how to resolve dryer problems.

fyi , i am a union certified electrician , so power is the 1st thing i checked...120v.....secondly , the vent tube was packed , so i unhooked the hose and cleaned it out..i have not put it back on yet.....thirdly , the whole underneath compartment was also stuffed solid with lint ( in fact some of the lint was black from catching on fire ), so the old lady cleaned that completely out ....after all that is when im having the burner shut off after 10 seconds.... changed the 2 coils and same thing is happening.....i dont know if this means anything , but where the flame starts , 100% of the flame does not shoot straight out of the tube ( most all of the flame goes straight ) , it kinda creates almost a roundish flame about 1.5" in diameter , then it gets smaller and goes down the tube...is this roundish flame overheating the ceramic pieces that sit just behind it , because the flame does touch them

Based on this new information, there is a possibility of an air flow restriction as a result of a clogged fan blower housing and/or some where in the venting system of the dryer. May be a loose fan on the motor shaft or reduced motor speed do to motor age, some type of reduced air flow, etc.

Dry a load of clothes without the duct venting tube attached and see if there is an improvement. Dryer help and advice link in my first post already contains all the possibly causes and solutions. Worth reading, IMO.

May be the gas control vlave is defective. Restricting gas flow causing a smaller undersized flame or another type of gas flow restiction in the gas supply to the machine, etc.
