How To Fix A Dryer That Is Not Heating?

Dryer not heating or drying your clothing? If your dryer is all of a sudden not drying your clothes, then we have a few simple DIY fix tips you can try yourself. If the dryer is no longer drying your clothes then the first thing to do is to check and clean the dryer lint filter trap.

Check Dryer Lint Filter

We were forced to add that as our first step as there really are some people who do not realize there is a LINT FILTER that must be cleaned before or after each use. Once that is cleaned out, check if the dryer is still NOT drying your clothes.

Check Vent Hose On Back Of Dryer

If that was NOT the cause of the problem, then you will need to inspect the vent hose on the back of the dryer. Commonly this HOT AIR VENT HOSE will become clogged, caked or full of lint that is constantly being removed from your clothing when drying. When this happens your dryer is unable to expel the hot air from within, therefore making it impossible for your dryer to actually dry your clothing in a timely manner or at all.

Common Causes For Dryer To Stop Heating

  1. The dryer lint screen (lint trap) has not been cleaned (poor or restricted airflow).
  2. A clogged or kinked (bent) dryer air vent hose (inadequate or no airflow).
  3. Drum has stopped turning, broken drum drive belt.
  4. Overheated or bad motor (possible thermal overload).
  5. Thermal fuse or thermostat (could be caused from dryer air vent hose lint buildup)
  6. Heating element burnt out.
  7. Loose electrical plug or power socket.
  8. Other mechanical issue, fault or malfunction.

Clothing Takes Forever To Dry

If your clothes dryer is taking forever to dry your clothes or it is not drying your clothing at all (and you already thoroughly cleaned the lint filter screen), then the first step is to CLEAN OUT THE INSIDE OF THE DRYER VENT HOSE.

First, unplug your dryer from the electrical socket on the wall. Slide the dryer forward very carefully so you can get behind it. Locate the (usually silver colored) air vent hose, and remove it from the wall and the dryer (2 connection points).

Do this by squeezing the clip at both ends and pulling the hose outward. Using a long dryer vent brush or similar, clean out the inside of the air vent hose by removing all of the built up lint and dust looking material.

Clean the area on the back of the dryer and the hole in the wall where the air is vented out. Most of the time the lint will be built up in both of these areas.

Once all of the lint is cleaned out, reattach the vent hose and slide the dryer back in place. Make sure you DO NOT KINK the vent hose when repositioning the dryer as this will cause the dryer to NOT expel the hot air properly.

If you kink the hose the dryer will not function properly and your clothes will take forever to dry. Next, plug the dryer back into the power outlet and run a test. If your dryer is now heating and properly drying your clothes then you fixed the problem. If not, read on…

Dryer Has Overheated

At times your dryer can overheat and this can cause the motor that turns the drum to stop working temporarily. There is a safety mechanism built into the motor that makes it stop working if it gets too hot. This is called a thermally protected motor.

Your dryer may seem to be running but the motor will not be turning the drum. If the drum is not turning then the clothes are not moving. Therefore they can not get DRY. So if your dryer motor is NOT turning on but the rest of the dryer works, such as the lights and other mechanical parts, then your motor is probably overheated.

For this, you need to just give the motor some time to cool down. If you suspect that this is your problem then give the dryer about an hour to cool down and run a test after that. If your motor has overheated then you may be overloading your dryer with too many clothes. Try running the dryer with less clothes in it the next time you dry a load and this should remedy the issue.

The solutions above are the most common causes for this specific malfunction. If the explanations above have not been your specific problem, then there can be a number of things wrong. If you feel comfortable you can remove the front panel of your dryer (while unplugged) and look to see if there are any obvious causes of the problem.

A possible loose wire, loose part, burnt area, pieces of the dryer that have come off, fried or burned mechanical switches, etc. If the problem is not visual and you do not know what the issue can be, we recommend going here and posting an appliance repair question to online appliance repair technicians. If all else fails then simply leave a comment or question below and we PROMISE to answer your question in a timely manner.

Other components that could be at fault would be the Thermal fuse, Thermal cutoff, Heating element, Operating thermostat, and High limit thermostat. You can check all of these for continuity with a multimeter. If any are determined bad, remove and replace.

  1. Just want to take a moment to thank the folks maintaining and contributing to this site. It has an incredible amount of useful information. I had trouble with my dryer not drying the clothes fully and I found this site googling for the problem. Thankfully my issue was fixed at step 2 by clearing the air vent hose. But I was curious and read all the next steps just in case I needed to work on any of those. I found that the instructions were explained in a simple and concise manner which was very helpful for a novice like me. Much appreciated.

    Patrick,
    Whirlpool Cabrio Dryer PF error code = 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.
    Whirlpool Cabrio Dryer AF error code = Restricted Airflow Condition = AF flashes if a restricted airflow condition exists. Check to make sure the lint screen is clean, the door seal is in place and the vent is not obstructed.

    If the timer is malfunctioning, check the board for any issues such as burn or scorch marks. If you reset the dryer, does the error code reset?

  3. Our Whirlpool Cabrio Model#WED7800XWO is displaying error codes ‘PF’/’AF’. I have checked the lint screen, cleared the vent hose all the way to the outside. It also intermittently jumps time on the countdown timer. Went from 45 minutes to 5 minutes in just under 10.

    Paul,
    The switch that controls the heat temp could be faulty. There may be a wiring issue. Unplug the dryer and have a look in the control panel for wiring issue. You may also have a bad thermostat or other related part. Here is a parts guide to your Samsung Dryer DV218AGW.

  5. I have a Samsung Dryer dv218agw/xaa. The dryer works on medium heat, but it barley heats up when the high heat setting is selected (it gives about the same heat a low). Do you have an idea about what might causing this and how to fix it.

    Hily,
    If you have 2 dryers, are they both hooked to the same vent? Check the wall or vent hoses to be sure you do not have a lint blockage. If you have 2 dryers that both will spin but they both stopped heating at the same time, it is most likely the vent is clogged, or possibly you lost part of the power. Are the dryers electric? Are they both on the same circuit breaker? Possible that there are 2 breakers and one has flipped into the off position?
    -RR

  7. I have 2 dryers that are brand new they will start but won’t heat up to dry the clothes. Any ideas as to what it could be?

    Sylvia,
    Can you look in and see if the igniter is glowing red?
    If you DO see it glowing red and then it fades off without any burner ignition, the cause is a weak solenoid coil or coils.

    If you DO NOT see any red glow, the failure could be one of the following parts:
    Timer, Hi-limit thermostat, Operating thermostat, Thermal fuse, Igniter, Motor centrifugal switch, or Flame sensor.
    Let us know what you find.

    Heather,
    If the dryer spins and HEATS, then you most likely have lint blockage behind the dryer. Clean out the vent hose and the wall. Heavy lint buildup will not allow the hot air to escape, therefore your clothes take forever to dry.

  10. I have a whirlpool dryer that is not drying my clothes. It heats up and the drum is turning, but it takes sometimes days at a time to get a load of laundry dry. I do clean the filter all the time, so I don’t really know what the problem is. Anyone have any idea what it could be?
