The vent was 90% crimped for a long time. The dryer heat comes and goes. Does a digital compputerized dryer have a thermal fuse that you can replace?

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.

check out this electric no heat tip...

Thermal fuse blows after one load, why?


Hello,
The most typical reason that would make a thermal fuse blow so fast is the venting either being crushed,blocked or restricted in some manner. When the vent is blocked the heat that is pass through the clothing then vents out is being retained inside of the dryer where is could build up to a level where it could cause a fire,to prevent dryer fires all dryers are required to have this thermal fuse that will totally stop the machine from running once it goes out. Is this dryer brand new and did you experience drying issues with your old one? if yes the venting is defiently the problem. In most cases there is a screen where the vent exits to the exterior of the house and that screen is blocked w/lint, it snaps out and be cleaned easily.

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 .

Roper rgx5634kq2 gas dryer. Starts out lighting like it should. It runs for a minute or two then flame goes out, then after a minute it comes back on. It will do this cycle a few times and then it will...


it's not the thermal fuse,the dryer wouldn't run and the ignitor wouldn't glow.sounds like you have bad gas coils,if the dryer runs for the first 15 to 30 minutes normally and then no more flame the coils are failing,when they are bad they work until they heat up and then nothing,when they cool down they work again,common problem,also you should clean out the dryer once a year ,clean out the duct that the lint filter slides into,if your vent line is long take it off from the back of the dryer and blow it out with a leaf blower,make sure the outside vent is clear first,you can have a fire and then you can pop the thermal fuse,clean it and your clothes will dry on time,let me know what you find

Dryer wont start


most of these dryers have a thermal fuse that shuts the dryer down when it over heats and it is not resetable. most of these on a kenmore are on the back of the dryer. locate the thermal fuse and use an ohm meter to tell if it has continuity or not. no continuity - replace it.

also if your dryer is over heating one of the most common causes is a crimped vent hose or pipe. don't use plastic hose as it crimps shut easily and won't let the heat out of the dryer causing the problem you described.

My gas dryer has no heat


long dry times are a venting problem. if no heat at all it could be your ignitor, a thermal fuse, or the secondary gas coils, all are replaceable and reasanoblyy cheap between 30-90 dollars usually so its up to u it u want to repair it.. if long dry times i would unplug the venting from the rear and dry a load if it heats faster than u know ur venting is clogged and u might wanna clean ur ducting and replace that venting tube. also u can go outside while running and see or feel if air is being pushed out while its running hope this helps let me know how it goes

NO HEAT COMING FROM DRYER


Hi, thanks for the inquiry.

If it's a gas dryer, it's most likely a thermal fuse. Basically, the voltage has to go through the fuse
Before it goes to the ignitor.
If it's an electric, it's either the heating element or the thermal cut-off, most of the time.
Either way, it should only cost you about $90 to repair if it's a gas, and between $100 and $120 if it's an electric.

Best of luck :)

Maytag gas dryer not heating


You may want to disconnect the vent from the back of the dryer and try it. Flame rollback will cycle the burner off by the high limit.

Considering what you have already done to it, if the problem still exists you probably have bad coils on the gas valve. make sure you replace them as a set.

The thermal fuse is a one time device. If it opens, the burner will not come on at all.
