Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes 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 different things that can go wrong causing the dryer not to heat.

Hi, i have a whirlpool duet sport wfw8400tw03. When i run to normal cycle, it stop no error code no light. The washing machine just shut down. I can run it on delicate or sanitary.Is a balance trouble


if u can run it on delicate or fluff cycle with cool air more than likely its ur cycling thermostat or the hi limit thermostat going defective test it with a meter for ohms..
1. On gas and electric dryers that have an "Auto Dry" cycle, the cycling thermostat is often used to advance the timer as well regulate the drum temperature. Essentially, thermostat will alternately turn on the heat source or the timer motor when the temperature has been satisfied. To check this thermostat, you will have to check for power to the timer motor with a multi-meter, during a cycle. This is a live voltage test and caution should be used.

2. Some dryers will use a cool down thermostat to tumble the clothes without heat, at the end of the dry cycle. Power is routed through this thermostat to the drive motor to keep it running until the drum temperature has dropped to a specific temperature. If this thermostat fails it can cause the drum to turn indefinitely or until the door is opened. You can check the thermostat for continuity with a multi-meter. This test should only be made with the power removed from the dryer.

Lastly check the moister sensor for OHMS according to ur schematic as it must show a certain amount of ohms as per ur unit. When unit has been on short while



DRYER OVERHEATING:

Heating Element
A defective heating element can make a dryer too hot or not heat at all. . If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.

Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

HI LIMIT THERMOSTAT DEFECTIVE? SHOULD SHOW OHMS AT ROOM TEMPERATURE


Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

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 .

ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

Samsung front load electric dryer not getting hot


There is a thermal sensor type breaker leading to the heating element. They are usually round, about quarter size, with a spade connector on each end. They can be checked by a OHM meter to see if they make a connection from one terminal to the other. There may be more than one. If that checks good then you need to check the heating elements for resistance for one end to the other. If there is no resistance then the element is bad.

Stopped heating


What I do is see if their could be an obvious reason for the dryer to quit heating. I determine how old the dryer is and ask if the heating element has been replaced and when, those sorts of questions then that give me an idea. I make it a point to clean and oil any dryer I work o. They all are going to have lint buildup in them and this lint is the main cause of heat failure. A small piece of lint gets on the heating element and causes a hot spot. The hot spot burns through interrupting the circuit93b855d.jpg
I unplug the machine and remove the rear cover. 1c9e8bc.jpg I 1. Hi Limit (small limit upper right hand side of this pic) the most frequent problem if dryer RUNS but no heat AND you have
checked the element and found it to be good. 2. Heater assembly. 7. Control thermostat(s). 5. Fuse(350F), if blown(open) the dryer will NOT run. 4. Heater element
(if you do not have a meter remove and inspect this heater coil for breaks). I remove the lint chute(that the thing the filter lives in) and I wash that out because it gets clogged over time. I check the heater and limits for continuity. Then I remove the front panel and drum. Completely vacuum out the dryer and oil the rollers. d4f393f.jpg
If this is a gas dryer you want to see if power is going to the gas assembly
If this fuseeda36f9.jpg is blown on a gas dryer the dryer will run but the heat will not, If the dryer heats a little but quits then these coils are getting hot and intermittent94fb1fe.jpgif your igniter is blown a54d451.jpgor your sensor is open5650218.jpgthere won't be no heat.

Dryer will not get hot. All the vents are clean.


Check for burnt out heating element and electrical connections to element and thermostats. If okay check all thermostats, operating and high limit, with an ohm meter. All must be in closed position. If element,thermostats,and electrical connections good then check timer.

Whirlpool electric dryer that will not heat up, dryer comes on and turns, but no heat


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


this happen a lot on this dryers locate the heat sensor on the back of the dryer is located near the exit air duct it looks like a white piece of plastic with 2 wires on it get a volt meter and test it for conductivity this sensor control the heater element and if the air coming out from the duct is to hot this sensor burns so make sure your duct line is clear and don't put just few clothes on it because your dryer will get too hot again and it will burn this sensor again go to a repair shop for dryers and get one they only cost like 5 dls bye a second one to have it ready if happen again and if this sensor is good then check your heater element for conductivity heater element is only like 20 dls

My dryer won'y blow hot air


bpaul...first, check to see if you have full power to the unit. These units run on 220 volts which involves two breakers linked together...my guess is one popped and you're running on 110. You'll get some functions but not full heat. Turn the breakers off and back on. Not it? Then check for lint in the piping which is causing a false reading on your temp sensor.
