TYPICAL DRYER PROBLEMS AND SOLUTIONS
"Typical dryer problems and solutions"
REMEMBER THIS: WHEN MESSING WITH DRYER PLEASE UNPLUG IT!
Top ten problems:
If a dryer is not working at all thats not good! But it doesn't mean you need to go appliance shopping just yet.It may be something very simple like a bad door switch or even a broken door switch actuator,in a kenmore dryer there is a tab thats sticks out of a hole in the wall that allows the dryer to run only if the door is shut, other models may have button that protrudes out of the dryer and when the door is shut, this allows the dryer to run. These switches go out from time to time,also if a dryer is full of lint build-up over time this will cause the dryer high limit or fuse to blow. The fuse is located near where the blower is in most cases. When the air in the dryer gets way too hot the fuse/hi-limit will blow and the house wont burn down. 2) Runs but drum dont turn:
Usually this means the belt is broken,the belt may have just been old and worn out and it was time to replace it,or perhaps the wheels locked up or the idler and caused the belt to break. Look around for stiff wheels, bad bearings, glides and idlers. Its a good idea to oil the rollers with some temp resistant oil such as zoom oil. Dont use WD40 as this stuff is highly flamable and may cause a fire.
3) Runs but dont heat:
Ok maybe the heating element got old and brittle over time and finally gave up the ghost. But it may not be the element. It could be one of the safety Hi-limits have blown. All parts of the dryer will have continuity if its working properly. Test for continuity by using a meter set on Ohms,or use a poormans meter. You can make your own poormans meter by using an ordinary flashlight . Break the circuit in the flashlight and add a couple of wires to it so that you can make the light come on in the flashlight ,thats right hot wire that flashlight. When the bulb lites up you have a circuit! You now have a poormans meter. The next step is to check each little gizmo on the dryer that the wires attach to. All the little black thingies attached to the side of the heat element ,the door switch (when door is closed) ETC.should have continuity(closed circuit)(the light should come on in the poormans meter) If you come across any little thingie near the blower housing with 2 wires attached to it, well that a sensor, a safety ,(Now so as not to get a false circuit you need to remove one of the wires to each thingie you check) where was I? oh yeah.It safe guards you from having to call 911. These things blow because of lint and too many clothes or blocked vent going out the house or all of the above.
4) Runs but takes a long time to dry the clothes:
Sometimes blower wheels will get loose in dryers. Sometimes they will get a whole lump of lint in them . Sometimes you can hear a rattling noise in the dryer, this is the blower wheel,its worn out and it can cause the fuse to blow too,or it can half *** work and take fifty forevers to dry the clothes.Or it could be just that the dryer needs a good blowing out .I use a lawn blower to get all the lint out of the dryer as well as the vent pipe and vent to outside. I take the filter HOUSING out and wash it also. That is, I remove the housing and clean is good! Making sure that the dryer is properly flowing air is a good thing!
All dryers have to have a way of allowing the tumbler(thats the thang you put the clothes in) to turn freely, not all of them are the same tho,some use bearings, some use slides,others use rollers. Over time these rollers will need to be oiled,the slides will get thin and start metal to metal contact causing a noise, The rear bearings will then start to make their way to china and cause the tumbler to rub into the heating element and OUCH! These things will cause the motor to prematurely DIE! Its best to examine the dryers, rollers, and slides when you first hear the noise, but who does?
6) Runs and never stops:
In all probability this may well be the timer motor has quit,and thus the timer needs replacing right? Maybe, but you need to first check to see if your dryer has a moister sensing system, If the sensor board contacts get corroded or goes caput, then the dryer wont know when to advance and shut off in newer models!
7) Runs for a few minutes then quits:
This is probably the motor going bad. The sensors wont cause this to happen. The start switch either, replacing all the sensors in the world wont make the motor be good again. But their is something you can do to try and make the motor last a while longer,their isn't any holes to oil the dryer motor so you must make some,using a 1/8th inch drill bit make a hole in either end of the motor where the bearings are(taking care not to hit the shaft) ,then add some hi temp oil such as zoom-oil,(dont use WD-40) and work the motor free as you can by hand . If this frees up the motor it may go a while longer. Also oil the rollers and check the slides to make sure they are not pinching and stalling the motor. If the motor can't reach top speed it will get hot,overload and stop.
8) Runs only if you hold the button down:
this is the motor trying to get up to top speed but it cant for some reason do it (see above). Some folks try and trick the dryer into staying on by lodging something in between the switch and letting it dry,but the sad reality is the motor is probably shot and needs to be replaced. The switch itself is not the fault, all it does is start the motor up and then the secondary windings in it take over, if the motor is dragging it will not switch over to the run mode, it soon will die anyway.
9) Runs but KEEPS blowing fuse:
Almost all the time this is because of a heavy lint problem some where in the housing of the lint trap. Keeping the lint filter housing clean will stop the fuses from blowing.THIS MEAN REMOVING THE HOUSING AND WASHING IT OUT THROUGHLY!
10) Runs beautiful at repair shop, dead at home:
This an electrical problem usualy caused by a bad breaker or a bad receptacle where the cord is plugged in,In fact bad breakers can cause you to have fits trying to figure out why the dryer wont work. If the dryer breaker is over 20 years old it may need replacing.

SOURCE: I have a Whirlpool Front
If the drum is kinda hard to turn then you may need to get inside the dryer and yank out the filter first.Remove the 2 screws in the filter housing on top.Then use a putty knife to pop the top. Remove the screws holding the front panel on. VERY IMPORTANT! Raise the front up an inch before pulling forward or the panel clips will break! Some models have a panel on bottom. If they do then this panel must come off first. Then you remove the door springs and back off the screws holding down the bottom of the door panel. Then pop the top and remove the screws on top to get the panel out of your way. Get the drum out and check the wheels and idler assembly. Some of newer dryers have a crappy sliding type idler. I replace that with a generic on with a wheel. I use high temp resistant zoomoil from the hardware store($2). You can also oil the motor if it is stiff but you will have carefull make some oil ports. The manufacturer does not provide any. Zoomoil works well in these motors. hey it might save you a few bucks. It is worth a shot.
