    HEAT TEST: Watch this video or follow the step by step instructions below:

    1. Cool and empty the dryer.

      Let the unit cool down, remove the drying rack and literature and do not load anything in the drum.

      Kempty the dryer
    2. Activate heat test.

      Press the buttons described in the sequence below.

      Signal Button Method

      • Press POWER, TEMP., and SIGNAL (DAMP DRY) buttons all at the same time until code In5 appears.

      • For some models, press the Power, then Temp., and Signal.

      • Press POWER, TEMP., and DAMP DRY buttons all at the same time. until code In5 appears.

      • For some models, press the buttons one at a time.

      Timed Dry Method

      • Power the dryer ON, and set the cycle to TIMED DRY.

      • Use the TEMP. button to select the highest heat.

      • Then Press the START/PAUSE to begin test. Test run will take up to 1 minutes.

      • You may need to try a couple of times to get code In5 display.

      • If non of the methods above displays code In5, please download a copy of your owner's manual from our Manuals and Documents page for model-specific instructions.


    3. Do you see code In5?

      • Keep an eye on the display screen for code or any other error code.

      • Using the timed dry method, the In5 may not display, proceed to Step 5.

      • For other error codes, please visit Error Codes - Dryer to resolve the error and restart the heat test.

      • If you cannot get code In5 to display, please proceed to Step 5

      Code In5
    4. Start heat test.

      • Press the START/PAUSE to begin test. This test will take up to 3 minutes.

      • will display after 3 minutes and a chime sounds when the test is completed.

      • Keep an eye on the Flow SenseTM indicator on the control panel.

      start the heat test
    5. Check heat & flow sense results

      • How many bars are lit up on the FLOW SENSE indicator?

      • Now, open the dryer and feel the inside of the drum, does it feel warm?

      start the heat test

      Select your result from the options below:


Back

When no bars appear on the flow sense and the dryer feels warm, the unit is experiencing LONG DRYING TIME issue. The unit is heating and there is NO air flow restrictions. The likely culprit of this long drying time is either of the following:

  1. Start the dryer, does the ENERGY SAVER button light up?

    If you do not have an energy saver button, choose No.

    Using the Energy Saver Light Yes No
  2. Energy saver mode is designed to reduce energy consumption by operating the unit with very low heat, making drying duration longer. You can turn off energy saver mode each time you use the dryer by pressing the ENERGY SAVER button.

    The light on the button will turn off, and your clothes should dry properly now.

    Do you want to disable energy saver permanently?

    Yes No
  3. One more step, let's check your lint filter.


    Proceed to Lint Filter

When the lint filter is dirty or clogged, it will cause long time drying. Always clean the lint from the filter after every cycle. Open the dryer door and pull the lint filter straight up.

pull the lint filter

Clean the lint filter using any of the options below:

Everyday

For everyday cleaning, roll any lint off the filter with your fingers or a long handle brush.

clean the the lint filter

Clean with vacuum

Use a vacuum cleaner to clean the lint filter.

vacuum the lint filter

Wash with water

If the lint filter has become very dirty or clogged with fabric softener, wash the lint filter in warm, soapy water and allow it to dry thoroughly before reinstalling.

wash the lint filter

One more step, let's check your load size.


Proceed to Bulky Loads
  1. How would you describe the load size you are trying to dry?

    Small to Medium Large
  2. If you are not sure about the load size, check the Large Load option too.

    • When drying smaller size loads, it may be better to use TIME DRY instead of sensor dry to achieve better drying performance.

    • The only place we need to check now for optimum performance is the moisture sensor.

  3. If you are not sure about the load size, check the Small to Medium Load option too.

    • As long as the items can freely tumble in the dryer, the load is fine.

    • If the clothes are unable to tumble, then the load is too large and some items will need to be removed.

    • The other piece that needs to be functioning properly for the correct dryness level to be achieved are the moisture sensors.

The correct dryness level of the machine is achieved by the moisture sensor. If the sensors are clogged, the sensors can read incorrect dryness level and cause the unit to shut off before all the items are dry.

If you have tried all the recommended solutions above and the unit is not heating, the unit may require a repair service. Please visit our Request a Repair page.

When no bars appear on the flow sense and the dryer feels cold, this is a NOT HEATING ISSUE issue and there is NO air flow obstructions. Follow the troubleshooting steps below to resolve the issue.

  1. Is your dryer GAS or ELECTRIC?

    Gas Electric
  2. Do you have another GAS appliance in the house?

    Yes No
  3. Is the gas running across the other appliance?

    Yes No
  4. Is the gas running throughout the house?

    Yes No Not Sure
  5. Okay, let's check the gas connection to the unit and a couple of other factors that can lead to not heating.

    1. Check gas connection

    2. Check gas valve

    3. Pinched gas line

    If you are not sure that gas is not flowing in the house, contact your gas company to do some proper check before requesting for a professional technician.

    If you have performed the recommended solution in this article and the unit is still not heating, the unit will require a repair service. Please visit our Request a Repair page.

  6. It seems like gas is not flowing to the house. You will need to contact your gas company for further assistance.

  7. Make sure that the plug is securely plugged into a grounded outlet matching the dryer's rating plate.

    check power plug
    • Put your dryer on power OFF.

    • Reset your house or apartment circuit panel by turning OFF the dryer's breaker for at least 10 seconds to clear the power surge inside the breaker.

    • Put your dryer on power ON.

    • Re-run the heat test again.

    • If the dryer is still not heating at this stage, further troubleshooting would require taking the unit apart, testing individual components, and this is best performed by a professional technician.

Back

When 2 or 4 bars appear on the flow sense and the dryer feels warm, the dryer is experiencing LONG DRYING TIME and there is AIR FLOW OBSTRUCTIONS in the exhaust duct vent.

  • Check energy saver mode and clear any obstructions blocking the duct vents.

  • Air flow obstructions can be the result of excessively long or kinked ductwork, lint buildup in the ductwork, buildup on the lint filter, or an oversized load.

  1. Start the dryer, does the ENERGY SAVER button light up?

    If you do not have an energy saver button, choose No.

    Using the Energy Saver Light Yes No
  2. Energy saver mode is designed to reduce energy consumption by operating the unit with very low heat, making drying duration longer. You can turn off energy saver mode each time you use the dryer by pressing the ENERGY SAVER button.

    The light on the button will turn off, and your clothes should dry properly now.

    Do you want to disable energy saver permanently?

    Yes No

  3. One more step, let's check for some air flow obstructions.


    Proceed to Air Flow Obstructions

The hot, humid air from the dryer has to go somewhere, or else the moisture will stay in the drum and clothes. 2 or 4 four bars on the flowsense indicates that the exhaust system is severely restricted. The video below explains blockages and air flow restriction in the vent system, watch the video or follow the steps underneath.

There is a short test you can perform to identify whether the restriction is inside the dryer or outside of it.

  1. Test without exhaust duct

    To get started, you will need a sheer, nylon stocking (to collect lint), medium sized rubber band, and a load of wet laundry.

    • Unplug the dryer from the wall outlet.

    • Remove the vent duct from the back of the dryer.

    • Place the stocking over the outlet duct and secure with rubber band.

    • Plug the unit back in, clean the lint filter, and load the wet laundry into the dryer.

    • Select the TIMED DRY cycle for 30 Minutes and press START.

    • If the load is DRY - The vent must be checked for obstructions by a local vent or chimney cleaning company.

    • If the load is WET - Your dryer will require service. For your convenience, you can request a repair online using our Request a Repair page.

  2. Lint Buildup

    Check for lint buildup at the rear exhaust duct, the lint build up will cause long time drying in the dryer.

    If you need the service of a professional technician, contact a local chimney cleaning company to clean the vent.

  3. Damaged Exhaust

    A crushed or damaged exhaust will also cause air blockage. If possible, check every section of your exhaust duct to ensure it is not crushed, kinked or damaged.

  4. Crushed duct

    • Avoid long runs or runs with multiple elbows or bends.

    • Avoid excess or crushed transition duct.

    • Too many elbows or exhaust too long can also cause long time drying.

  5. Ductwork is too long

    When the ductwork is too long, or has too many bends, blockages can occur and it will be hard to trace. In this case, check the exterior part of the house when the machine is running to see if exhaust air is blowing outside.

    For proper inspection and repair of this situation, contact a local chimney cleaning company to clean the vent.

Back

When 2 or 4 bars appear on the flow sense and the dryer feels cold, there is problem at the POWER source of the dryer causing a NOT HEATING issue. You also need to check the duct vent for AIR FLOW OBSTRUCTIONS.

  • If your appliance is Gas/Electric, check power source following the troubleshooting steps below.

  • Air flow obstructions can be the result of excessively long or kinked ductwork, lint buildup in the ductwork, buildup on the lint filter, or an oversized load.

  1. Is your dryer GAS or ELECTRIC?

    Gas Electric
  2. Do you have another GAS appliance in the house?

    Yes No
