If the heating element has power going to it and there is no heat then the element is bad. If you have multimeter you can set it to ohms and check the element if there is ohms at the two element leads where you checked for power then the element is good but if the element shows no ohms or the meter doesn't beep if it has this feature then the element is no good.

Dryer won't heat I've replaced the heater element


Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

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 .

Dryer is running, but heat will not turn on


There are several things that can prevent a dryer from not heating.. Unplug Power Before checking.
Electric Models
1- Power- Your dryer runs on 220volts. 110 runs the entire dryer and 110 runs just the element. Your breaker may have half tripped. Check to see if you are getting the correct amount of power by using a ohm meter. Also check the power cord for burn marks on the plugin and the cord itself.
2- The thermal fuse can prevent this from heating. The thermal fuse is a sensor on the blower housing the measures the temperature of the air. There is a cycling thermistat near the thermal fuse. If the dryer temp gets over 190-220 degrees the thermal fuse will blow to cut power to the element to prevent fire. You can test this by using a continuity tester.
3- High limit and/or thermal cutoff. These are both sensors on the heating element housing. Thermal cutoff is at the top and the high limit is near the bottom above the heating element connectors. Test these with a continuity tester.
4- Heating element- Just below the high limit on the heater housing. Test for continuity.
5- Motor- The motor has to reach a certain rpm to activate a sinfrigrial switch inside the motor. If the rpm is not reached it will not allow current to go to the element.
6- Timer- Make sure you are trying this on timed dry. Sometimes people use air fluff and forget to change it back. The timer could also not be sending current to the heater.

Gas models
1- Electric ignitor- Inside the flame tunnel inside of dryer near where gas line hooks up. Usually if it glows than it is still good but check to see if it is sending and amp signal to the heat coils.
2- Heater coils are two valves that open up when the ignitor send signal saying the ignitor can ignite the gas. Heat coils will not open to send gas if it does not receive a signal from the ignotor. They look like two round disk with two wires running from ignitor.
3- Flame sensor- Change if you change the heater coils. The flame sensor could not be detecting the flame inside so it shuts down the ignitor.
4- Motor- See above
5- Timer See above

I have a Bosch nextt 500 series dryer and after 2 years of use the problem I have is the heat will shut off and the dryer will keep running and I have to press the reset button on the backside of the dryer


Open the front panel, remove heat exchanger and clean. also clean out lint tray. this might help a little. Now lets check if the thermal sensor or heating element needs to be replaced.
Unplug the dryer. remove the panel in the back of the dryer that covers the heating element. ( the inner panel). On top of the heating element you will see a thermal sensor with a small red button on it. Thats the manual reset button. To test if the heating element is working properly you can disconnect the wires from the sensor and clip the connectors together . Plug the dryer back in and start it. pay attention to the heating element. It should begin to glow shortly. if it doesn't then your heating element is bad and needs to be replaced.

Unplug the dryer. Connect the wires back to the thermal sensor. Plug the dryer back in. Before you start the dryer, press the red button on the thermal sensor. Start the dryer. If the heating element doesn't come on and dryer doesn't heat, then you need to replace that sensor.

My Kenmore Elite dryer just quit heating up...is it the heating element or possibly a fuse? The lint trap had qite a bit of lint in it..maybe it just over heated and blew a fuse?


There is a thermal sensor attached to the housing of the heating element, you can check the thermal sensor by jumpering the two wires to the thermal sensor together, and then run the dryer and see if the heating element is now working, if the dryer is now heating up then replace the thermal sensor.

Hi


Thanks for using FixYa. Things that could stop an electric dryer from heating: - house fuse or breaker (needs two of them), heating element, burnt wire, thermostat(s), thermal fuse (not all models), motor heat switch, timer, selector switch, burnt power cord/plug.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

No heat in dryer model # 96591420


Check the following to address this issue.




1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

3. 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.

No heat


check the thermal cut-off. it's on the element housing. when that goes out, the element will not heat up. good luck :) just check for continuity. it comes in a package with a new thermastat. replace both of them.
