    I have 110 Volts on both legs on the terminal block when checked against the middle nuetural. Wires look good

    Timer motor runs and stops when I open the door so that looks good as well.



    Any other thoughts?

    Jumped out door switch and Start switch. Same issue



    Also held volt meter against both 110 ( one at a time) legs comming in and depressed start. No voltage drop

  • tbarr616 Mar 11, 2009

    Ohmed out the thermal fuse with both wires off.



    Reading was 0.



    Thermal fuse is located on on the exhaust manafold approx. 6 inches from the exhaust exit where the hose goes on.



    Thermal fuse is the small white block with 2 wires.



    Its also located right next to the cycling thermostat that has 4 wires going to it.

  • tbarr616 Mar 11, 2009

    belt is not broken but I didn't check the belt switch.



    I dont see it in my wiring diagram that is attached to the rear cover of the drier. And visual inspection I don't see it either.



    Where would that be located? That might be it

  • tbarr616 Mar 11, 2009

    There is no 4m or 5m on the start switch.



    Do you mean the motor?



    If so that might take me a while.



    Don't leave me just yet.



    Your advice is much needed and appreciated.

    Attached an external 110v power to M5 and M4 start switch on the motor and the motor TURNS

  • kevin692 Mar 13, 2009

    How do you test the timer switch? I have the same issue just won't run. changed the fuse and the start button

    Re-read my post.

    It said start switch on the motor.(not the push to start switch)

  • steve
    steve May 11, 2010

    If it is not on the diagram that model does not have a belt switch.

    Remove the start switch wires on the motor.

    Make a 110v cord and connect to 4m and 5m on the start switch and see if the motor comes on.

  • steve

    Did you verify the belt is not broken...opening the belt switch?

  • steve
    steve May 11, 2010

    Did you read the thermal fuse with wires attached or removed?

    Where was the thermal fuse located?

  • steve
    steve May 11, 2010

    With a volt meter, hold the meter leads to the incoming wire terminals and press start and see if you get a voltage drop.

  • steve
    steve May 11, 2010

    Jump out the door switch and the start switch.

  • steve
    steve May 11, 2010

    Closely examine the wiring at the terminal block where the cord attaches for a burned wire.

    Check each incoming wire to neutral for 110 volts to neutral.

Replace the dryer wires.
Put your meter leads into the 4&5 slots.
Make sure the door switch is closed or jumpered.
Push the start button.
If you read no voltage the issue is with the wiring, the timer, or a relay.

Electric dryer will not heat,everything else is working


Unplug power cord & pull the back off and use ohm meter to
to check the heating element also check if the element is ground to the heater box. Check the thermal fuse, the cutout fuse & thermostat on the heater box. Check the operating thermostat and any others you see. Last check the centrifucal switch on the motor the heating wire goes through it. To check this switch connect ohm meter to terminals it will show open unless motor is running so take a screwdriver & lift up on switch button then it should show continuity. Hope this helps

Whirlpool dryer wont heat


Hi Marlene Hatcher

Here are a few more things to check, you have checked some of these already:
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 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.

My dryer is no longer heating up and it does not time out, what parts would i need to fix the problems?


Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
A - Things that could stop a 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
Whirlpool style dryer - no heat problems:

Electric dryers - See the "how to take apart" section first if needed. Always check the power supply first...if one house fuse blows or 1/2 of the breaker trips, it is possible for the dryer to run with no heat. If you have a volt meter, you should read 240 volts between the red and black wires, 120 volts between the white and black and 120 volts between white and red, check for this at the main power connection. If you have 240 volts to the dryer, remove rear access panel, turn dryer on and test for 240 volts to the *heating element wire connections (#4). If you have 240 volts there and no heat = bad element, the element must be broken physically to be bad. If you have no power at the heating element, remove power, remove wires to the heating element and isolate them so that they can't touch anything. Reinstall power and check each wire for power from the wire to the dryer cabinet, one wire will probably show 120 volts and the other will show zero. Make note of the color or # of the wire that has no power, remove power to the dryer and check the wiring diagram that comes with the dryer to find out where that color or # wire goes to. EG: - wires might be yellow and red, if the yellow wire (example only) was the one that had no power, look at the wiring diagram to find out where that goes to and check only those parts, no need to check the other colored wire parts as they are working. Things to check are, *thermostats, timer contacts, selector switch, motor switch heat contacts ( 1&2 on the motor switch ) and *thermal fuse. If the wires to the heating element are the same color, just remove power after test and slowly follow that wire that has no power with your hand to see what parts it goes to. If live volt testing scares you, try the ohm checkinstead.
*#1-Thermal fuse that controls heat. If the dryer overheats, this fuse will blow. One shot fuse. Does not reset.
#2-Canister for the heater element.
#3-Hi limit thermostat. This thermostat is a safety thermostat in case the dryer severely overheats. When this safety thermostat is defective, it should raise a red flag for air flow problems.
#4-This is the terminals of the heater element that is inside the canister.
#5-Thermal fuse that controls motor run.
#6-Control thermostat. This is the thermostat that controls the cycling of the heater in high heat mode.
#7-Heater for low heat. When you select low heat, 110V is sent to this heater that the control thermostat sits in. The heater helps cycle the control thermostat faster, therefore you get less heat than the high heat mode.
You can get required parts from www.repairclinic.com
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Whirlpool dryer WED5530SQ0, heats but does not run


So,. basically your drum doesnt turn. SO your getting heat still even though the drum isnt turning. Is this right? Sounds strange??? Do you hear any humming noise when you push the start button? I need to know a little more about the problem because im kinda confused as how you decribed the problem. Iv never seen a dryer heat but the drum not spinning. especially your model dryer. Its electric heat right? because if the drum doesnt spin, maybe your motor is bad. and if your motor is bad, then your heating element wont heat up because the centrifical switch in the motor is not switching to complete the circuit to the heating element. So this is why im confused when you said" Dryer heats when knob turned but when "push button" pressed, drum doesnt run." Because your belt wraps around the motor pully and the motor is what makes the drum turn. Like i said, i never seen this model dryer heat with out the motor operating. So if you can give me some more info, ill do my best to help you out....Thanks!!!!

Kitchenaid superba dryer won't heat Where is the heater fuse located?


Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
A - Things that could stop a 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.
A ohm meter test for these parts is here.
Q - My gas dryer will not heat, what could stop my dryer from heating?
A - Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats,motor heat switch, timer, selector switch, sensor.
A page for checking gas dryers is here.
Meter testing and usage tips.
1. Power supply-check power supply at terminal block where cord enters the dryer. Should read 240V. If you read 240V here, tested with a volt meter, unplug dryer and test components with ohm meter.
2. Thermostats-Cycle and safety thermostats-read them with an ohm meter. Should show continuity . How common thermostats work.
3.Timer-The timer has a set of contacts that pass voltage to the heaters. If you can not determine by wiring picture what they are, check across the two terminals with the largest wires on them. The heater wires are almost twice as large as the others. You should read continuity with timer in heat mode.
4. Thermal fuses-In recent years the makers of dryers are using thermal fuses to let you know something is wrong with your dryer. They are generally non resetting and have to be replaced. The thermal fuses are located on the heater element housing and should read continuity if read with an ohm meter. Most blown thermal fuses are the result of vent/air flow problems or a grounded heating element.
5. Selector Switches-Read the wiring picture and determine which switch is closed. You should read continuity across closed switches.
6. Safety Switch on Motor-There is a safety switch on motor to insure that heaters can not come on unless motor is running. It is normally open when the motor is idle/not running, and closes when motor runs. In order to check with an ohm meter, remove the two large wires on motor switch and make them electrically safe. Tape them. Plug the dryer in and start motor. Check continuity across the terminals on the motor switch you removed the heavy wires from. If it is ok you should read continuity. Remember that the smaller wires in a dryer carry the 120V and the large wires carry 240V. There is no voltage on these two terminals with wires removed. It is ok to test with ohm meter.
7. Heat elements-Test heater element with an ohm meter. You will read continuityacross a good element ( 8-12 ohms is an average element ).
But darn it, I don't have a Ohm Meter....
To check the thermal fuse  - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.To check the thermal cut-out  - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.
To check the thermostats for continuity -  - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.
To check the Element: Try removing element and physically looking at the element wire for a break in the wire.

Whirlpool dryer wont start, replaced push-to-start switch unit. still doesnt work.


ENSURE THAT YOU HAVE POWER TO THE MACHINE AT THE BACK WHERE THE CORD CONNECTS. FROM THERE I WOULD TEST THE DOOR SWITCH. IF BOTH OF THOSE ARE FINE, I WOULD TEST CONTINUITY ON THE THERMAL FUSE MOUNTED ON THE HEATING ELEMENT. THERE ARE GENERALLY TWO THERMAL DEVICES ON THE ELEMENT AND IT IS THE SMALLER OF THE TWO WHICH IS MOUNTED HIGHER THAN THE OTHER. YOU SHOULD READ O OHMS ON A VOLTMETER. CHECK YOUR VENTING IF THE FUSE IS BLOW FOR ANY RESTRICTIONS

Whirlpool dryer won't run


This sounds like something may be mis-wired...or there may be a defective switch contact in the timer or one of the other controls. If the heater element comes on with the blower motor not running, it should quickly overheat and trip one of the thermal shutoff switches.
