Sorry to read about your problem.

Their is a 80% chance you have a defective heat coil or coils. or the heat selector switch is defective. if you pulled the covers to look at the heat coils. you must meter the coils. the thermal switch is close to the coil line.

Maytag Bravos XL Dryer not heating- blowing thermal fuse


The thermostat is controlling the temperature, however the Heating Coil may be defective. Check the COIL.

Tip

Whirlpool or Kenmore Dryer Does Not Heat


Electric

First , check the circuit breaker to make sure they are on . Be sure to UNPLUG the dryer , while checking with an ohm meter . When checking WITH power , BEST to have another person available in case of emergency . I do know of 1 person killed while working on his dryer .
A dryer operating on 240 volts , sends 120 volts to the timer and 120 volts to the motor . In between these two , are the thermal cut-off , and the element ( this is the basic operation parts ) . The 120 volts from the motor , goes directly to the element if selected for heat . The timer circuit , sends the other 120 volts , thru the operating thermostats , then thermal fuse , then thermal cut-off , then high-limit thermostat , then to the element . Usually , not ALL the time , the thermal fuse ( number 1 ) is the problem . The heating element ( number 2 ) is usually the problem , if the thermal fuse is good .
If the thermostats , element , and thermal fuse check good with an ohm meter , remove 1 wire from the element and check with a meter , which side is NOT getting 120 volts . Trace the wire which will either go to the timer ( occasionally ) or to the motor ( extremely rare ) .

Gas

On a gas dryer , for no heat , or , heats for a short time then runs but no heat afterwords until cooled down , first check that the electronic igniter , glows red . If it does NOT glow red , then check power to the burner ( 2 wires ) . If no power , then the thermal fuse is bad . (On electric dryers , the thermal fuse keeps the dryer from starting . On gas dryers , it keeps the dryer from heating . The thermal fuse , is a 1" long , or oval , white piece , with 2 wires going to it ) . Also if it does not glow red , the igniter itself could be bad . Again , check with an ohm meter . If the igniter glows red and clicks off , but no gas , the sensor could be bad . This sensor , is mounted to the side of the burner box , and when the igniter gets hot enough to ignite the gas , the sensor opens , sending power to the coils , which open dispensing the gas to heat the dryer . To check the sensor , with the drum removed , start the dryer , and after the igniter gets red , pull one of the wires OFF the sensor , and the gas should ignite . Do this very carefully , as electricity WILL be in the wire pulled off . If the dryer heats for a short time then stops heating , the problem will be the burner coils . These coils will get warm from the electricity going thru them , and will " open " ( short ) internally , until they cool down . Then heat again for a short time , then open , until cooled .
Most of the time , either the thermal fuse ( 1 ) or the coils are bad ( 2 ) or the igniter is bad ( 3 ) .

........A thermal fuse is a white 1" long torpedo looking piece , or , a white oval shaped piece , with 2 wires going to it .

NOTE1 : The thermal fuse keeps an electric dryer from starting and keeps a gas dryer from heating .

NOTE2 : If your dryer heats but the clothes do not dry , then a venting problem is obvious , as a dryer either heats or doesn't heat . Pull the dryer out and disconnect the vent from the dryer . Dry a load of clothes and if/when they dry in the normal amount of time , this tells you either the vent hose is kinked , maybe pushed back too far , or , the outside vent is blocked , or , the vent in the wall is restricted to the outside .

Electric Dryers

NOTE3 : If your lint screen is on top of the dryer , the element , thermal fuse , and thermostats are behind the rear dryer panel ....If the lint screen is behind the dryer door , then the element , thermal fuse ( located behind the lint screen housing ( 2 screws ) , and thermostats , are located behind the lower front panel .

A whirlpool gas dryer will not heat up


If your dryer is not getting any heat, you need to make sure there is nothing blocking the vent. IE: LINT. Air flow is key to efficient drying. Make sure the dryer settings are appropriate for the clothes you want to dry. The timer selection, fabric selection, and the temperature selection all play important roles in proper dryer operation.
Check the heating element, burner operation, ignitor, thermal fuse, and the wiring (power cord).
• Heating element (For Electric Models)
• Burner operation (For Gas Models)
• Ignitor (For Gas Models)
• Thermal fuse
I WOULD START WITH:
To protect from over-heating, many dryers use what's commonly called a thermal fuse. If the thermal fuse gets too hot, it will blow, and completely shut down your dryer until it is replaced. This fuse is often mounted within the exhaust duct in the back panel. It's about an inch long, and is usually found within a white plastic housing. When fuses blow, it means they have no continuity and no power will flow through it. A bad thermal fuse needs to be replaced. When replacing this fuse, check the dryer vents to make sure there is no lint buildup which can cause the heat to stay trapped and blow the fuse again.
Visually inspect your heating element for any broken or burned areas.Check the coil for continuity with a Volt Ohm Meter. If there's no continuity, it means that the element is bad and you need to replace it.
If the ignitor is cycling without the burner lighting, you probably have defective electrical coils in the gas valve. These coils look like black cylinders with wires coming out the top of them, and are located near the burner valve assembly. When they get power, they open up and allow the gas to get through to the burner. If this is a new installation, make sure the gas valve is turned on.

I have a dlb2450 model hot point dryer it seems to run fine but doesnt heat up ,where do i look first?


Hi
Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or inside of the dryer venting system,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the heating element/thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if you do not read continuity you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
Try to run the dryer, if it runs and heats up then replace the thermal fuse/thermistor/thermostat.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,then you do not have to tape the wires together as described above.
But do not trust the ohm meter all the time, because sometimes it will give a false positive that the fuse is ok when in reality it is faulty.
DO THE FOLLOWING TEST:
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check the fuse/thermostat,thermistor for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
This test of the thermal fuses,thermistor,thermostat, will show if the thermal fuse,thermostat,thermister is really faulty or not.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc. If you have to replace your blower wheel it will remove clockwise as looking at the blower wheel. You will have to hold the belt end of the motor with a vise grip pliers or maybe the shaft of the motor has a notch cut on it for a wrench to fit.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
If you do not have a volt/ohm meter then:
DO THE FOLLOWING: Remove the wires and tape them together and try to start the dryer.If the dryer starts then replace the fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on air fluff/no heat, and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Dryer is not heating up, but will tumble


Hello there and thank you for choosing fixya
This is a fairly common issue with dryers
There are only a few items that will make a dryer not heat Depending on your model
The first is the thermal fuse

To be fair, this failure's usually not the thermal fuse's fault, but the real cause lies in a partially (or completely) clogged dryer vent system. In those cases, the thermal fuse is just doing the job it was designed for.

Thermal fuses, or thermal cutoffs, are small electrical temperature sensitive 'switches' designed to interrupt electrical current flow when heated to their specific rated 'trip' temperature.

Unlike a thermostat, which automatically resets itself when the temperature drops, thermal fuses are more like their cousins, electrical fuses, another single-use type device that can't be reset and must be replaced when it fails or is triggered.

In addition to their legally mandated application in modern clothes dryers (since the 1980's), thermal fuses are used as safety devices in other heat-producing appliances like coffee makers and hair dryers. They disconnect the flow of current to the heating element in case of malfunction (such as a defective thermostat or clogged dryer vent) that allows the temperature to rise to dangerous levels, possibly starting a fire.looks lke thistbirdfan1_81.jpg

and the last thisn is the heating element it'self

most of them look similatr to this one below but once again yours may be differenttbirdfan1_82.jpg

Not heating up


check the wiring to the heating element and ensure all the connections are tight and there are no burned wires. The heating element should be continious with no breaks.
ohms should peg the meter if everything is good.

Whirlpoool dryer not heating replaced the thermostat


Dont know the model number you have, but most of your items are located in the back of the unit. You need to make sure you replaced the thermostat, and not just the thermal fuse. The thermal fuse sits on top of the element shield, the thermostat is lower, down where the wires go into the element. You may have changed the thermal fuse, but the thermostat may be out. You will need to check (with an ohm meter) all the componants to find the trouble. If that thermal cut-off has went bad again, change the thermostat with it. Be sure you have very good ventilation all the way through, bad vents will cause problems like this all the time. Let me know if you need parts info. Let me know a model number as well.

Heating element in Crosley Clothes dryer


Before you replace the heating element, check the thermal fuse. All heaters have safety thermal fuse. This opens in case the thermostat fails. This is normally attached on or near the heating element, looks like diode. (When replacing, do not solder ! this will damage the fuse)
