Gas clothes dryers use either natural gas or propane as a heat source. You'll find that gas dryers are a bit more expensive to purchase, $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. 

While a qualified technician is required in many states for any type of gas line repair, there are repairs you can make yourself that will save a service call.

Converting a Natural Gas Dryer to Liquid Propane 

Problem: Gas dryers come from the manufacturer ready to install with natural gas. However, some areas only have liquid propane gas available. Can the dryer still be used? 

  • Natural gas dryers connections can be easily converted 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.

Timer Will Not Work on LG Gas Dryer

Problem: LG dryer timer does not operate properly causing a 30-minute cycle to stop after twelve to fifteen minutes.

Can the timer be reset or repaired?

  • The timer is faulty. There is no way to "reset" the timer and it should be replaced. 

Diagnostic Codes for Kitchen Aid Gas Dryer

Problem: A Kitchen Aid Gas Dryer is not functioning properly and it is difficult to pinpoint the exact problem.

  • Before starting any type of repairs, running a diagnostic program will help determine where to begin and what repair parts may be needed.
  • Here are the fault codes for Kitchen Aid Gas Dryers with the 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 it is faulty.
  • E2: Temperature sensor shorted: E2 flashes in the numeric display when the temperature sensing circuit is shorted. Replace temperature sensor if it is 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.

    Proper Venting of Gas Dryer Exhaust 

    Problem: Outside venting for gas dryer will be difficult. Can it be vented into an unconditioned attic space?

    Amana Gas Dryer Burner Problem

    Problem: Igniter fires on  Amana gas dryer but burner does not light up.

    • There are several things that could be causing this problem: the dryer's thermal fuse, bad coils on the gas valve, or a blocked vent. To pinpoint the cause, start with a test of the vent because it is easy and there are 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 the back. Being careful not to damage the gas line or venting system. Then disconnect the 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 outside 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, safer metal tubing. 
    • If the venting system is metal tubing, it may have to be disconnected in sections to access the inside and clean it out. 
    • If this does not solve the problem, move to replacing the thermal fuse (inexpensive part) and then finally replacing the burner coils.

    GE Gas Dryer Not Working on Every Cycle

    Problem: GE gas dryer has four cycle settings but only works on three. It will not run on the cotton setting.

    Since the GE Gas Dryer is heating up properly on three of four 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.
