Question about Kenmore Dryers

1 Answer

My Gas Dryer only heats up when is cold.

After working 5 or 10 minutes, the flame doesn't start ( some kind of resistor gets red hot but the flame dosn't come back). If I turn off the Dryer and wait for 20 to 30 minutes and then turn it on again the machine will work fine for another 5 or 10 minutes.
I bought it on December 2002

    Hi, I have read your answer and I have a question: According to your knowlege the coil assembly in this case only works (consistently, because it has been working fine when is cold only for almost two weeks) when the machine is cold?

  • sergio_i_san Apr 15, 2009

    HI localwonder, are you there? I would like to hear your answer to my comment.

  • sergio_i_san Apr 15, 2009

    I need some help here. I have read the description names af all the parts from the REPAIR PARTS LIST belonging to this machine and I dont see any "coil assembly" it coud be under different name? ,

    I see only one coil 60 Hz (split) (3 terminal) (pilot position) and one coil 60Hz (2 terminal) (Main).

    Are these the same?.

  • sergio_i_san Apr 15, 2009

    Yes I read your RE POST, please see my comment # 3 in which I ask for clarification in the names of the "coils" I found in my part list.

  • sergio_i_san Apr 15, 2009

    I hope the solution is correct, I will know it after replacing the coils.

Hi there, your dryer has a set of bad coils that are malfunctioning. The red glow that you see is the glow ignition that is trying to re lite the burner. If the coil assembly is not functioning correctly, the valves will not open to release the gas for heating purposes. Replacing the coil Assembly will fix this erratic situation.

    Yes, this coil solenoid set will operate correctly at any temperature if its not malfunctioning or damaged. Your assembly is 7 years old and i assume you use your dryer regularly. When the coil/solenoid becomes unstable and the structure becomes flawed in time, it will tend to lose its ability to communicate with the control board. The internals of the coil will work until the heat raises during operational periods. being that this assembly is damaged , these normal operating temperature will make it hard for the damaged coil to do its job. The coil activates the solenoid and allows the gas to flow. when the starting temp is cold, this ,malfunction is not an issue because, the switch is easily moved when its cold but, at a running warmer temp, the switch will take more power to activate and, if the coil is weak and unstable, it will not open and close this valve. In return, preventing the gas to flow. you will need to replace the coils on this dryer.

    Yes, you are correct. The coil assembly consist of these devices you have stated in your response. These two parts make up the (coil assembly)--(#1 coil 60 Hz (split) (3 terminal) (pilot position) and #2 coil 60Hz (2 terminal) (Main). These will need to be replaced.

    There's a main and a secondary coil. two coils.

    They are connected to the burner assembly...

    The word assembly is used because, they work in unison.

Ge gas dryer heats but doesnt dry


if the flame is lighting you have lint blocking the air flow either in the dryer or in the vent line,also if you have a flame for the first 10 to 20 minutes and then the flame doesn't light you have bad gas coils located on top of the gas valve,when the coils are bad they can work for the first 10 to 20 minutes until the coils get hot and then they fail and you'll see the ignitor glowing orange but no flame,bad gas coils.then when the coils cool down they can work again.hope this helps.you can try removing the vent line from the back of the dryer and see if the flame stays on,if lint is blocking the air from blowing out the flame won't stay lit long enough to dry the clothes.

My whirlpool dryer comes on and runs good but it wont get hot can you tell me whats the problem


Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.




Enter your model number to see parts for your dryer.

Help me find my model number


Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.


Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.


Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

No Gas Flame


Very common problem. The solenoids when cold will sometime work once then get hot and fail. Replace the coils. I made a short video which shows how it works and how to replace the coils on a similar dryer with the same type of solenoids:

My Maytag gas dryer, Model No, LDG7500AAW will run but not heat. The igniter glows red, but the gas will not flow. What might be wrong?


Replace the 2 burner coils ,if the igniter keeps cycling trying to start the flame. If it doesn't replace the flame sensor mounted on the side of the burner tube.

When the dryer is cold the heater flame will


The heating circuit is working perfectly except for the solenoid coils as indicated by the occasional glowing of the igniter but no gas is ignited. A gas valve closes as the solenoid coil weakens as it gets hot and does not open until it has cooled down. Replace both gas valve solenoid coils to get the dryer back into proper operation. The solenoid coils are part numbers 694539 and 694540 but also can be purchased as a kit here.

Gas dryer heat is intermediate


does the igniter glow white or orange? if it is orange you need to replace it. has to be white hot to ignite. if the igniter is white it could be the coils not opening the gas valve all the time - an intermittent problem.

Maytag DG482 Dryer Won't Heat


The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor a%20flame%20sensor%202.bmp flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the ignitor
a%20igniter.jpg Ignitor and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot igniter and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly. So... If your gas dryer has a good flame sensor and a good igniter AND the dryer will work some and quit, replace these: dryer%20coil%20kit.jpg Gas operator coils
part# 279834
The coils get hot and quit on these machines when they get a little age on them. It is aggrevating because it is a hard to diagnose thing. But well worth the 20 bucks. SOURCE
