Gas neptune dryer fires up for 45 sec. to 1 min, then goes out

Checked air flow and replace coil pack on the gas valve and no change even ran the dryer without the vent hose connected. It will not remain fired or refire unless restarted and the fire on duration is 30 seconds or less.

Could be a couple different things,Possibly a thermostat or high limit that is kicking out too soon,also has a flame sensor next to the burner that can come and go.if you have a toggle switch or pushbutton switch you can unplug the unit take the two wires off the flame sensor (black box about the size of a cigarette pack on the left of the burner)plug them into the switch start the dryer Turn the switch on till the igniter glows bright,turn the switch off and the burner will light if it stays lit at least till it gets to temp replace the flame sensor.(It won't cycle with out flipping the switch each time)

Gas dryer works fine for 5 min., then flame goes out, display time goes to 1 min. (cool down mode). I've tested high limit thermostat. It is OK. I put on new gas coils. Error codes 3 and 10 appear on


Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?

Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

I have a Maytag dryer (Gas) Model # MDG8506AWW. I changed the ignitor and also the coils on the gas valve, same problem. Ignitor turns on, heats up, gas valve opens burner turns on and then shuts off...


Hello,

Is their rumbling noise at start up (or was thier in the past) if so the blower wheel itn't turning and its causing the flame to sufficate due to very poor or no air flow , to check if blower wheel is problem remove vent from back of dryer and check for air that should be equal to if not better than that of a box fan you would use in your living room,if good air flow at back of dryer check for blocked or restricted vent,Again very poor air flow will sufficate the flame very quickly


If this helps please give me 4 thumbs up :)

Kitchen aid dryer / heat flame not staying on after 20 secs


Sounds like your gas valve is fine, if it comes on at all, its good. A air flow restriction would cause a overheat condition and shut down the burner. Once it cools back down the burner would re-ignite and repeat the cycle. The sensor on the left of the burner is the flame sensor and the flame wouldn't come on at all if it was bad. You've already changed the coil kit so the valve is fine, disconnect the vent from the back of the dryer and see if the problem goes away. If the problem stays, I would suspect the thermostat. Good luck.

Gas burner only stays on for 5 seconds off 1 to 2 min.taks two hours dry clothes


No air flow. Blocked venting , Blower wheel broken or cloged. Check to see if the air is blowing out side at your vent. If your ingitor comes back on but no flame your gas coils are no good.

Maytag dryer turns on, the heating element glows, but the gas won't kick in. The drum turns but the fire won't start.


I would suspect faulty gas valve coils. These electrical coils are above the gas valves and when energized, these solenoids open the gas valves and permit gas flow to the burner. If faulty there is no gas flow and the burner cannot light. It is recommended that if any are suspected of being faulty that both (all) be replaced at the same time and will most likely come from the part supplier as a set. Really sorry for your trouble and I hope this helped. Best wishes.

Gas dryer, ignites, runs for 30 sec. then goes out, runs 2 min, reignites, burns for 30 sec and goes back out


This is most likely caused by faulty gas valve coils. The electrical coils are right above the gas valves and when energized, these solenoids open the gas valves to permit gas flow. A symptom of bad solenoids is a "cycling" condition such as you have described. It is recommended that if any solenoids are suspected of being faulty that they both (all) be replaced at the same time. They will most likely come as a set. Hope this helped and best wishes.

Neptune Gas dryer burner will not continue to fire


There's a good chance you need to replace the igniter. Careful, they are brittle !!!

Burner wont stay lite for more than 60 sec.


There are two things which could cause this.
First, if there is insufficient air flow, and second would be if one of the coils on the gas valve open up as it warms (as current flows through it). If you have good air flow out the outside exhaust with this problem, replace the gas valve. (coils are not available individually, even though you can swap out the coils from the old and new valve without physically changing the entire valve)
