Maytag gas dryer igniter doesn't work all the time

I have a Maytag gas dryer model D6 9900 which I purchased new 5/23/92. The board was replaced 11/24/97.

I put a new igniter in last year 2/15/01. The ignitor seems to light the unit when cool but is not reigniting after the unit has been running awhile. It comes on and glows but the gas valve does not seem to open. If I let it cool down and restart the machine, it will ignite. Can you tell me what I should check or would you recommend I call Maytag repair?

Thanks in advance.

Thanks for your help so far.

I discovered tonight that when the igniter won't light the gas there is a vibrating noise that sounds like it is coming from the gas solenoids. I put a nut driver on the selinod and held it to my ear. It seemed to bear out the idea that the vibration was coming from the gas solenoids.
Do you think I should go buy the part or should I try to find a parts company that tests parts? I 've tried three companies so far and none test parts.

Hello nolanswift,
Check the hot surface ignitor or glow coil for continuity and you may want to perform an amp draw on it also.Continuity is checked with appliance unplugged,amp draw is done with appliance operating If you're not sure about doing this or don't feel comfortable,call a service technician.

Arrow Restricted Exhaust Vent

Hello: Nolan

Chances are the exhaust vent is restricted and or clogged.
Below is a list of possible problems including the vent problem.

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.

Timer:
Control center for all functions. The timer has internal contacts and as it advances through the cycles, one of those contacts can become burned out, stuck opened or closed for any one of several reasons. Timers also have cams <lobes> that open and close those contact points. If the timer hangs-up on a lobe, it may or may not advance to the next cycle.

If the timer or any other selection switch, on the front control panel, is suspected of causing the existing problem your having with the appliance, be sure all selections are correctly set.

If they are, the timer or other function selected switch may be defective. Timers are a non repairable item. Any or all of the control panels switches can be removed and taken to the local appliance retail parts store for testing.

Timers and switches can also be checked for continuity using an ohm meter or continuity tester. However, do not rely soley on a continuity test for proper timer functioning. Timers and switches are a non repairable items.

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 a 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 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 any required tests.

Suggestions:
Read the manufacturers online web site for obtaining product information, problem causes, possibilities and solving methods, part locations, disassembly, reassembly, repair proceedures and methods, instructions, pictorials and schematics, which may be available online.

An excellent source for orginal replacement parts is your local retail appliance parts store. Appliance parts dealers test and carry replacement parts for all appliances. Parts dealers are listed in the phone book under appliances.

Retail parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers if you stop in at the store. The info will help to determine the exact parts used in the model assembly line run and possible problem causes.

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.
