Question about Dryers

2 Answers

Once we put a load of wet clothes in the dryer after about 3 minutes the dryer shuts off. The top of the dryer becomes extremely hot. We open the dryer door and let it cool down and then the dryer starts up ok. I think that it may be the temperature sensor switch. How difficult is it to replace one of them. Does the entire drum have to be removed?

The solution is probably a simple one. It sounds like you have an exhaust problem. Your exhast could be clogged with lint or with water if the hose has a dip in it. The exhaust fan circulates the heat and brings in fresh, (cooler and dryer) air, then it goes out thru the exhaust hose. The expelled air has a great deal of moisture in it, if there is a dip in the exhaust hose, the moisture will collect at the lowest point, thereby filling up and forming a seal, much the way the trap under your sink works. If the fan is working, this is where I would start. You can check easily by disconnecting the hose from the dryer and attaching a pair of panty hose over the flange, (to trap the lint), then turn the dryer on. If the hose fills with air, your fan is working. If the dryer does not heat up and quit, your exaust hose is clogged somewhere.

Wet clothing doesn't allow proper ventilation while tumbling clothes. This in turn causes electrical shorts: steam in chamber and reduces airflow. Reduced airflow will will cause the drier to shut off on an over temperature condition. Moral of story, spin clothes as dry as you can and when tumbling, make sure you have good ventilation to get best results.

Maytag dryer se1000 runs for 15 minutes then shuts off


Clean your sensors if you have them. They might have junk on them that could be forming a moisture barrier preventing the sensors from feeling the wetness of them clothes. The dryer may think them clothes is dry because it cannot sense wetness.

if it still quits heating after a minute or so then its either a weak cycling thermostat or moisture sensor thermistor,both located on the blower housing, or the moisture sensor bars located near the door opening on the dryer,or it could be a high limit thermostat thats bad on the burner tube itself

Kenmore Electric Dryer Model 110-C62662101. Dryer won't stop running. Will run all day long until door is open.


Problem with the timer control unit as it is not switching off until reset with the door latch.
it is possible that the dryer control relay or driver is short and giving power continuously.

Kenmore dryer will stop in mid cycle and beep 3 times in succession. What does that mean? Already had a repairman out and he replaced the circuit board.


Use some windex to clean the wax buildup off the dryer sensors under the filter housing inside the dryer.9bc0002.jpg Autodry VS electronic sensing: First, wet clothes are electrically conductive. With electronic sensing dryers as the wet clothes tumble, they touch the two metal bars in the drum. (Auto dry dryers utilize a system of cycling the timer motor with the element, and has nothing to do with how wet the clothes are by the way.) There is a capacitor on the control that is trying to build up a charge, but when wet clothes create a short from one bar to the other, this charge is released to the frame of the dryer, therefore discharging the capacitor. As long as the capacitor charge is low, the control knows the clothes are wet. As the clothes become dryer, they short the bars fewer and fewer times. Once the capacitor charge builds to a certain level, the control knows the clothes are mostly dry, and it advances the program to the final timed portion, usually less than 20 minutes, some of which is a cool down portion to reduce wrinkling. If your dryer is shutting off after only 10 minutes, that means the control capacitor is never getting discharged. This can be due to a few different reasons: 1. Sensing bar wire is disconnected or broken; 2. Load is not large enough (remember the bars must be contacted repeatedly); 3. Bars are "coated" by fabric softener build up and need to be cleaned with Windex or 409. 4. Defective control board. 5. Airflow is restricted and moisture can't escape the drum. 6. Corrosion built-up on sensing board connection.(yank out the board and clean the contacts that sometimes is all it takes) Address the airflow condition and load size. Clean the sensor bars and make sure the wires are all connected securely. There is a diagnostic mode you can enter to test the control's ability to sense the bar contact that is illustrated in the tech sheet which is located within the control panel on many models. No sensing bars means you have auto-dry a totally different animal. Typically an orange wire is connected to the high limit on the heater element housing which feeds the timer motor when the element is not in operation. Bad control thermostat or air restrictions are the Autodry type dryer's worst enemy. Special thanks to a.g.

My electric dryer is becoming extremely hot during the drying cycle. I replaced a blown thermal fuse several weeks ago and the dryer was extremely hot at that time. The dryer runs but becomes so hot you...


Clothes will get very hot in the dry cycle, especially when the dryer is set to the warmest or hottest setting.
There are controls built into the unit to prevent it from overheating to the point of causing a fire. The thermal fuse you replaced is one of them (and I assume you replaced a perfectly good fuse with a new one as you said it was very hot.).
You might want to check the following if you feel the unit is getting too hot -

1) Make sure the lint screen is clean.
2) Make sure the hose between the back of the dryer and the exhaust duct at the wall wall is not kinked or full of lint.
3) Make sure the exhaust duct leading to outside of the house is clear and not full of lint.

Let me know what you find.

Back & top of dryer get hot, clothes take long time to dry.


First thing to check for is blocked airflow. Check the dryer as well as the venting from the back of the dryer to the outside of the house good airflow is neccessary. You could remove the venting from the back of the dryer and run a load to see if that helps. Do not leave it off as it is exhausting lint and if a gas dryer spent fuel.

Dryer shuts off prematurely


The E1 code is a replace control panel code and a good way to check a sensor is to open the door with a empty machine and at the top of the opening there is a switch. Press it and start the dryer, watch the indicator for the sensor then get a wet finger and hold it across the two silver bars in the dryer, if it senses then maybe it is a mixed load or how is the machine leveled? I will lower the machine toward the sensor for better contact because after 3-5 passes the machine will assume the clothes are dry. If the sensor doesnt read then there is a question with the two mov varistors attached to a pig tail before the sensor. Here is a link to see what they look like.
