Gas clothes dryers use either natural gas or propane as a heat source. You'll find that gas dryers are a bit more expensive-$50 to $150 more than comparable electric models-but are more economical to operate. However, as with any appliance, there can be problems and a need for repairs. The Spruce readers have shared their issues with gas dryers and asked for help. Perhaps these solutions will help you as well.

Is There a Difference in Setting Up an LP vs Natural Gas Clothes Dryer?

Reader Question: I'm getting ready to rent a house that has a liquid propane (LP) gas source. I am looking to buy a dryer from someone that is a natural gas dryer; they told me that it won't work with LP gas. But I've read some sites saying yes it will, and some saying it will need a conversion kit? I'm quite confused. Could you please tell me whether or not I can hook a natural gas dryer up to a LP gas line without any problem or necessary conversion?

The Spruce: Gas dryers come from the manufacturer ready to install with natural gas. However, you can easily convert the connection to LP (liquid propane) with a conversion kit. The kit comes with instructions, but note: This is not just a quick connector change. You must open the dryer and do conversion work on the gas burner. Always check the building code regulations in your community for the installation of gas appliances.

You may need a licensed technician. Place a call to your local utility for more information and safety requirements. If you need a repair manual for the dryer, you can find it here and gas conversion kits can be found here.

How do I reset the Timer for an LG gas dryer?

Reader Question: How do I reset the timer for LG gas dryer?

The dryer timer is inaccurate. If the timer is set at 45 minutes, the cycle will end randomly after 12-15 minutes. For a custom setting, the dryer also runs much less time than it should. The clothes never dry the first cycle setting. The dryer needs to constantly be set numerous times before the clothes are dry.

The Spruce: Obviously, the timer is faulty. There is no way to "reset" the timer and it should be replaced. If you need a user or repair manual, you can find it here and replacement parts here.

Diagnostic Codes for Kitchen Aid Gas Dryer

Reader Question: How does one pull diagnostic codes on a Kitchen Aid Gas Dryer Model # KGHS0lPMT1?  The dryer runs but there is no heat. I have pulled front cover and there is no flame. I am trying to determine cause and whether I can order a part to replace. Thank you for any help.

The Spruce: Here are the fault codes definitions showing Failure Code first, fault code description, and finally the solution:

  • PF: Power failure: PF flashes to indicate that a power failure occurred while the dryer was running. Press Start to continue the cycle, or press Pause/Cancel to clear the display.
  • E1: Temperature sensor open: E1 flashes in the numeric display when the temperature sensing circuit is open. Replace temperature sensor if faulty.
  • E2: Temperature sensor shorted: E2 flashes in the numeric display when the temperature sensing circuit is shorted. Replace temperature sensor if faulty.
  • E3: Blower rotation failure: If during a cycle the blower rotational speed drops below 500 rpms, all outputs will be turned off and error code E3 will be displayed.
  • E4: Tumbler rotation failure: If during a cycle the tumbler rotational speed drops to 0, all outputs will be turned off and error code E4 will be displayed.
  • E5: Dry rack sensor: If during a Dry Rack cycle the signal is lost, all outputs are turned off and E5 is displayed.
  • E6: Exhaust high limit fault: If the exhaust temperature goes above 87.7°C (190°F) all outputs will turn off and E6 will be displayed.

Can I Vent a Gas Dryer into my Home's Attic Space?

Reader Question: Can I vent my gas dryer into my attic space?

It is going to be too hard to vent it outside.

The Spruce: Can you vent a gas dryer to the attic? Yes. SHOULD you vent a gas dryer to the attic? NO! Neither a gas nor electric clothes dryer should be vented to an indoor space because the moisture they exhaust can cause the growth of mold and mildew.

It is essential that gas dryers be installed properly. Learn how to select the correct dryer venting to prevent house fires.

If venting a dryer properly is difficult or impossible, consider purchasing a ventless clothes dryer.

Problem with Amana Gas Dryer Burner

Reader Question: My Amana gas dryer model# LG8319W2, mfg. in 2008, is not working correctly. The igniter flickers, but the burner does not light up. This problem happened suddenly without previous indications. I think it could be a rheostat type sensor in the burner chamber because this button style sensor on the side of the burner cylinder pops out and makes a click type sound when the igniter lights up. I unscrewed the gas flow plug screw on the manifold and gas flowed there. I checked all the connections and cleaned the exhaust venting.

The Spruce: There are several things that could be causing this-your thermal fuse, bad coils on the gas valve, or a blocked vent. Start with the vent test because it is easy and no parts to replace!

Unplug the dryer from the electrical power source. Turn off the gas to the machine at the gas supply line. There should be a shut off valve on the supply pipe for this purpose. Once that is accomplished, pull the machine out so you can access behind it. Being careful not to damage the gas line or venting system. Then disconnect the vent from the dryer. 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 hood flapper door. The flapper must be freely able to move. To clean the venting system you'll most likely have to remove the venting plastic tubing if plastic is used.

Best bet is to simply replace it with new tubing. It's inexpensive & easy to work with.

If the venting system is metal tubing, it may have to be disconnected in sections to access the inside and clean it out. Do not forget to inspect and clean as needed the outside vent hood. Inside the hood is a flapper vent. It should freely be able to flap up and down. If not free it up and or replace it.

If this does not solve the problem, move to replacing the thermal fuse (inexpensive part) and then finally replacing the burner coils.

Why does my GE Gas Dryer Not Work on One Cycle?

Reader Question: My GE gas dryer has four settings, but when I use the cotton setting, is not drying the clothes. It doesn't even get warm on the cotton setting but will dry clothes on the other settings. It's a GE Model # DHDSR46GE2WW.

The Spruce: Since your GE Gas Dryer is heating up on other cycles, it is most likely a malfunctioning thermostat or gas valve. Cotton is the hottest setting so this failure is signaling trouble ahead for every cycle. Test the thermostat and check the valves and do the repairs now.
