Question and Answers

Q:

Why does my Amana heavy duty 4 cycle gas dryer work for about 2 minutes then the gas flame shuts off by itself?

A:

Since the burner initially ignites, this indicates that most of the components in the heating circuit are okay. The symptoms you describe point to weak gas valve coils or a vent restriction.

The gas valve coils may be operating correctly when they are cold. As they heat up during operation, they could be too weak to keep the gas valves open and will not open during subsequent ignition attempts. The basic theory of operation for the gas valve assembly is shown in the image below.

A severe vent restriction could cause the short cycling of the burner. Although a gas dryer should always be properly vented to the outside of the home, you can try a temporary test of the venting by following these steps:

  1. Ventilate your laundry room as much as possible.
  2. Remove the flexible exhaust vent on the back of the dryer so that it will vent temporarily into the laundry room during this test.
  3. Position the dryer so that you can measure the exhaust air temperature coming out of the back of the dryer with an accurate thermometer.
  4. Clean the lint screen. NOTE: If you use dryer softener sheets you may need to thoroughly wash the lint screen with water and a nylon brush periodically to remove residue that can inhibit air flow through the lint screen. This residue is often hard to detect.
  5. Fill the dryer with a medium load of wet towels.
  6. Start a normal heated cycle.
  7. Measure the temperature coming out of the exhaust vent in the back of the dryer. It should heat up to about 150 degrees and then cycle between 130 and 150 degrees.
  8. If the dryer cycles properly while venting directly into the laundry room, then you will need to resolve the restriction in your vent duct system that goes to the outside of your home.
  9. If the dryer only heats for the two minutes and then never heats again, then it is more likely that you have weak gas valve coils as discussed above.
  10. Make sure that you reconnect the vent duct system as soon as you complete this test. The dryer should always be vented properly to the outside of the home during normal operation.

Without a model number for your Amana dryer, it is difficult to provide more specific technical help. If you need more help, resubmit your question with additional details and the full model number of your Amana dryer.

The previous answer provided general tips that were obviously not applicable to your model of Amana dryer. With a full model number, I am sure that we can provide more accurate technical advice if you need it and want to fix this problem yourself.

Hello, thanks for the response. It's a Kenmore gas dryer p/n 11074812200. Is there any way to see the gas valve operation thru the little "peep hole" in the lower front panel? Thanks, Bob

For bob60559: The first image below shows the location of an observation plug in the front panel of your Kenmore dryer below the door. You can remove that plug and observe the gas burner assembly on your dryer while it is running. The second image below provides specific technical information about the gas burner assembly in your exact dryer. The third image shows how to open the cabinet on this type of dryer. I provided one more image below that shows how to replace the gas valve coils (kit 279834) if necessary in your dryer. Be sure that you UNPLUG the dryer and shut off the gas supply before accessing internal components. If you need more help, reply with additional details.

I have a similar problem with an Amana gas dryer, model # NDG5805AWW. I'm pretty sure I need to replace the gas valve assembly. Dryer will ignite once and run thru it's cycle, but will not ignite again after that. I can hear the "click" of what I believe is the gas valve trying to open, and the igniter does glow bright orang, but no flame. If in fact it is the gas valve, can you walk me through that process?

For Mike: It does sound like you have weak gas valve coils in the dryer. Replacing those coils will probably fix your problem. The first image below shows the gas valve assembly on this dryer. The part number for the gas valve coil kit on this dryer is 12001349. You can order that kit from the Sears PartsDirect.com website. I provided a link for that site below this reply (2nd link). UNPLUG the dryer and shut off the gas supply before accessing internal components. The second and third images show how to access the gas valve assembly in this dryer. I provided a video in the first link below that shows how to replace the gas valve coils in a similar (Whirlpool) dryer. The access of the gas valve is slightly different but the procedure for replacing the valve coils is the same. I provided a written procedure for replacing the gas valve coils in the 4th image below. This information should help you complete this repair. If you need more help, reply with additional details. If you are not completely confident that you can properly complete this repair, I recommend that you have a technician repair the dryer. I provided a link for the Sears Service website in below the parts link.

Thanks this is very helpful. I was going to purchase the entire gas valve, didn't think I could just purchase the coils. I have checked another parts supplier, AP Wagner, they happen to have a warehouse in my area where I could pick up. On their site when I enter the part number, they have 2 sets of coils that come up, one is referred to as an M style coil. Is there a difference? Which should I be purchasing?

A:

The M coils (probably part number 279834) are the ones shown in the video that I provided. They are essentially the same and should work. Technical publications on this dryer indicate that a technician can use that set of valve coils instead of the other set (12001349). The valve coil kit costs a lot less than the entire gas valve assembly. The coils are likely the only problem. It is worth it to try to repair this failure by just replacing the valve coils instead of replacing the entire gas valve assembly. I am glad that you found the part locally. This should help you get the dryer fixed faster. If you need more help, reply with additional details.
