Tip & How-To about Dryers

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 stopped working. Not spinning or anything


You will be needing someone with an electric meter, (an ohm meter or a multi-meter) to begin testing to find out if it is the dryer or the power source.
The one thing you could do is check the fuse panel or the circuit breaker box to see if a circuit breaker popped or a fuse blew.
The circuit breaker can be reset by flipping the handle a few times, a fuse would need replacement.
Other than that, an electric meter will tell if the plug socket is live or dead, and then the machine needs be taken apart to see which part has failed. Usually a fuse or a thermo-switch has popped inside the machine.
God bless your efforts.

A Kennmore electric dryer, model 697267. Heating element checks out ok. Soninlaw said breakers are ok. Dryer drum turns but no heat? I'm 640 miles away, is there a thermal fuse in the circuit.


Yes there is a thermal fuse and a hi limit switch. The hi limit switch is attached to the heating element casing. You said the heating element checks out If you checked it with an ohm meter and it checked out good. If you checked it visually double check it. The hi limit can be checked with an ohm meter it should show continuity. If you dont have a ohm meter you can jump the wires by connecting them using a paper clip or copper wire. Make sure to tape them with electric tape. The thermal fuse is connected with the Heating element and hi limit by one wire and is located at the bottom back of the dryer and slightly to the right as you face the back of the dryer. It is a small two wire fuse and once it trips you have to replace it you can check it and test it just like the hi limit switch. Be careful and always unplug the dryer before starting any repairs. I hope this help. If you need me to clarify anything just let me know. good luck

MY OLD GE ELECTRIC DRYER TURNS ON BUT WILL NOT HEAT


Hi,


Make sure you check these to fix the problem.
  • Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.

  • Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.

  • A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.


Thank you

No heat coming from dryer


Double check the circuit breaker for the dryer (Electric Neptune). Turn it off, then turn it back on. Its possible that the breaker may have tripped for some reason, but wasn't able to trip all the way.

Does the interior of the dryer get warm at all? You could have a 1 of multiple heating elements that has shorted. If no heat at all, the likely a heating element has opened up. Unplug dryer from wall (turn off circuit breaker first!). Use a ohm meter to measure and check continuity of the heating elements.

There may also be a sail switch in the air path of the dryer. The purpose of the sail switch is to keep the elements turned off until there is enough air blowing through the dryer. This helps prevent fires, as well as shrunken denim.
