Question about Dryers

Dryer not heating

Heating element and thermal fuses have tested O.K. On multimeter, it seems that it is not getting any power. Cable to the mains and cable to the control board has continuity. Any help would be greatly received as just had a daughter and am about to have to wash and dry a hell of a lot of clothes in winter. Thank You.

Hi Mark
Here are a few things to check, you may have already check some, some needs checking.
********************************

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 heating element/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.

    Tank you, I found an additional thermistor in a style that I had not encountered before (looked like a thermocouple) and sure enough it was the culprit. Now I just have to work out what to ask my thruster parts vendor for. I think I'll probably go with black temp doo-hickey.

Thermostat controls heat. There is also a

motor centrifulgal switch, in the element

circuit, that the motor closes to insure

the motor is turning. Try another heat

setting. There is more than one

thermostat. You may have blown the

'thermal fuse' too, which requires

replacement. The elecment has a contact in

the 'timer' circuit too.

It is possible that your element has

failed also.

Tripped high limit. Must clean the lint

filter and the exhaust vent tube and all

the way in to the dryer. Hot air exit is

restricted.

Investigate these five areas if your dryer is not heating up:

Proper Voltage

If your dryer won't heat up, it's possible that it is not being supplied with the proper voltage. Here are three ways to make sure power is getting to your dryer: First, make sure your dryer is plugged in. Next, check the circuit breaker panel to make sure all the circuit breakers are in the correct positions. Finally, check to make sure no fuses in your fuse panel are blown. Any of these could explain why power is not getting to your dryer.

    Maytag dryer is not heat up. I think the heating


    Hello, There are a couple of variations of the heating element, depending on the series number of your dryer.

    Here's a link to the parts list and line drawing so you can verify the proper element you need.

    http://www.searspartsdirect.com/partsdirect/getSubComp.pd?modelNumber=SDE4606AYW&productCategoryId=0151200&brandId=3048&modelName=MAYTAG-LAUNDRY&diagramPageId=00005&componentDescription=REAR%20BLKHD,%20AIR%20DUCT,%20ROLLER&HTR%20(ELE)&documentId=M0510059&blt=06

    If you have a Series 14 dryer, the element part number is #37001134, otherwise, there are a couple of other elements that your particular dryer might use, so check the model number and product tag so you can get the right parts.

    You might want to check the element first, to make sure it is defective, before you order replacement parts, as it might be a faulty thermal fuse, which is much less expensive to replace than the heating element.

    If you have a multimeter, you can check the fuse to see if it's failed. Be sure to turn the power off and unplug the dryer before removing the back access panel and checking the thermal fuse (see drawing in link above)

    With the meter set to measure resisitance (Ohms) you can put a test lead on each side of the thermal fuse and if you get a reading showing no continuitity, then the thermal fuse is blown and needs to be replaced.

    You can also check the heating element using the same method, again, make sure the dryer is unplugged before testing the continuity of the heating element, if you don't get a continuity reading, then the heating element is bad too.

    I hope you find this Very Helpful and best regards!

    My dryer comes on but it doesn"t get hot.


    This is usually caused by a blown thermal fuse or faulty heating element. Both components can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity will indicate a faulty component. The thermal fuse is the most likely cause. It is about an inch long and is located just inside the rear of the dryer. It is usually attached to or near the exhaust duct. Sorry for your trouble and I sure hope this helps. Best wishes.

    Dryer not heating...everything seems OK


    Y'ou are zeroing in on your problem. Read the info below and hopefully you will have your answer:
    If your dryer doesn't heat, check these:

    Power from the house
    Heating element
    Thermal fuse
    Wiring
    Power from the house 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.

    Heating element 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.

    Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)

    Wiring 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.
