    The burner and gas runs into the bottom of the dryer. Does anyone know how to get to the burner?

  • rwhite3500 May 30, 2009

    Thank you. I was able to locate the 2 black coils.



    Does the whole igniter asembly have to be removed to get the coils out or will removing the two philips head screws holding them in be sufficient?

  • rwhite3500 May 30, 2009

    Thank you. You were very helpful. I'll have to order the parts and will be back in touch.

    Best regards,

Hi. i would recommend checking all component's below for faults. replace any that are defective or damaged.


1. Gas valve coils
igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. igniter
igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.

    The gas valve assembly is a whole piece. the burner, igniter,coils and, regulators are all one piece and, the gas flex tube is connected to this assembly. just follow the flex gas tube to the burner. it will be located on the back side of the oven on the lower right or left hand side. just pull the kick panel to access.

Normal 0 Hi, You need to change the coils on the top of the gas valve. This is a very common problem with the newer gas dryers.
UNPLUG the dryer. This model you need to remove the two screws under the lint screen. Now use a flat blade screw drive and insert it in the gap between the top and the front panel and pry the top up. Now locate and remove the screws on the inside of the front panel in upper corners. The front should lift off. You will see the two black coils on the gas valve. When you remove the three wire coil, make sure the sleeve inside it gets put back on the post thecoils slides onto.
If I can assist you further, please let me know.

Thanks
Vic

Dryer shuts after one minute


If it heats then you're getting 240 to the dryer. Take off the vent hose and look for a lint build up in the hose and where it connects to the house. Restriction will cause the dryer to shut off the heat to avoid a fire.

Whirlpool Imperial Series Dryer is Not Drying But Has Heat


Make sure it's blowing air out the vent outside. But even though it's heating doesn't mean it's heating 100 percent so u might need a heating element. Not to expensive to buy and often not to hard to change, refer to owners Manuel or a computer on how to change it.

Dryer won't dry


Well lets talk about it a minute. The ignitor is ok because it does glow. The flame sensor is ok because the ignitor is working. The only other thing in the circuit is the solenoids. So what goes wrong? Those coils get hot and quit with age.7ecd66c.jpg Replace them and the dryer will come back to life.5dc4e80.jpg

Whirlpool dryer won't dry


If your dryer spins and heats properly and the clothes don't dry, then very simply put, the moist air is not being taken away. If your drying temp is adequate, then the problem is with the exhaust. Go to where the air is being exhausted outside your home, if working properly, when you put your hand on the air coming out, it should get damp very quickly. And ALWAYS clean the lint trap after every load!!!!

Dryer does not release any heat


Is yours the gas model? If so I need you to look for some things. Open back door panel and see if while trying to light the igniter is glowing orange. Sea Breeze

Heat only works for a minute and then the heat stops


There is a thermostat that regulates temperature. Your dryer MIGHT be overheating. Check your lint filter, vent, and vent hose for blockage first. If not, it might be time to replace the heating element.

No heat after a minute of drying


Your GAS dryer has no element.
You should remove the vent from the rear of the dryer.
Run on hi heat with no laundry.
Your exhaust temperature should be from 130 to 165 degrees.
If not you have a thermostat problem or a ignitor/gas valve problem.

Whirlpool dryer - element heats, then shuts off quickly


Sounds like you have a stopped up vent on your home, when the vent gets stopped up the dryer can't circulate the air properly in the dryer and causes it to get to hot which causes the high limit thermostat to kill power to the element. If you need more help with this visit the link below:
