Hi,
I have a 15 year old Maytag Dryer. When You start it the coil lights, the burner fires for about 7 seconds then it shuts the gas down. I do have access to a DVOM for testing but I'm not sure what tests to perform and have been unable to find this info.
Thanks in advance for your help.

Hello Ray. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.
Below is a list of possibilities that may or may not apply.
Pick and choose what applies to your dryers current condition.
Other items you may need to do or want to check/do {whichever applies} while your in the process of repairing the dryer. Pick and choose as needed.
Restricted Exhaust Vent:
The vent tube is located behind or to the side of the dryer. It needs to be removed totally from both sides to completely clear out the lint. Check the entire system. This also includes the exhaust vent hood outside. It has a flapper that may not be opening fully or not at all. Locate any restriction within the entire exhaust system and clean out all lint. Replace exhaust vent tubing as needed. Plastic vent tubing is fine.
Defective Solenoids:
There are two...both are on top of the gas valve.
Solenoids also supply voltage to the glow coil and are part of the electrical loop. You'll need to remove them from the top of the gas valve by removing the entire gas valve assembly first. Take them off the gas valve body by removing the holddown cover plate or take the entire gas valve unit to your local appliance parts store and have the entire assembly and parts tested.
Defective Gas Valve:
Remove entire unit as an assembly. Take the entire assembly to your local appliance parts store for testing. Gas valves are not repairable. Replacement is the only option if defective.
CAUTION: Do Not attempt to repair the gas valve! This is a non repairable item!
Defective Glow Coil:
It's a rare possibility but worth noting here. The glow coil may glow but just be too weak to allow current to continue to flow to the coils. The solenoid coils are also part of the electrical loop and may effect proper glow coil operation or functioning.
Flame Sensor:
This part is located on the burner housing. If it's defective, it will cause the glow coil to not function or cause the problem your discribing. You can test this part with a continuity tester or an ohm meter. However, do not soley rely on this test to prove the part is functioning correctly. The only proof positive method to be sure the part is functioning correctly, is to carefully remove the part and have the local appliance parts store person do the testing.
Safety Reminder:
ALWAYS be positive you have unplugged the electrical power and turned off the gas supply to the appliance prior to attempting any repairs!
FYI:
The do-it-yourself person can do electrical tests and continuity tests on several of the parts. There are parts such as flame sensors, timers, solenoids, gas valves, etc. when neither of these tests will provide proof positive the part is actually functioning correctly. Therefore, do not rely solely on either test.
TIP:
Best method is to determine if any part is funtioning correctly is to carefully remove the part or parts you suspect to be the potential culprit, and have the local appliance parts store person run the required tests.
Check the ARCHIVES, within this forum, for other postings on this topic for further information. It is adviseable to inspect, clean the exhaust venting system whenever working on a dryer.
Regards & Good Luck
