If all of the components are reading ok then you need a timer. Touch your 2 leads together. 0 ohms rght. That means you have a complete circuit.If you get the 0 reading then the element must be otay. Bad timer. Take that fancy meater of yours and atttach one of them leads to the timer leg marked RH. Yank the wire off the terminal beore you test. Move the timer around. You should get the famous 0 reading along the way. If you don't then that means you have the bad timer.

SOURCE: I have a Kenmore Dryer Mod 110.96291100. No heat -

The element should not be zero... it should have some resistance...if not it is shorted out and will not heat...

There could be a number of different problems...
Check out this tip that I wrote about this problem...

SOURCE: electric dryer spins no heat, replaced heater

in addation to checking the high limit t-stat have you checked the thermal cut off (the small t-stat) on the heater housing where the element fits into, the high limit t-stat and the thermal cut off BOTH shoud have 0 ohms (the thermal fuse is in the blower housing) the cut off is on the heater box, if you have checked those to be good, check that the heat relay on the control board is closing and sending power to the element, if not replace the control, if all above are good then the motor switch is bad and not sending power to the element(thats a built in safety feature so the dry would never heat when the motor isnt running)the element of course heats only when 240 volts ac is to the element ,120vac from the relay on control through the high limit t-stat then through the thermal cut off finally to the element and 120vac from the motor switch for a comined 240 vac

SOURCE: LER7646 won't heat. I checked

Hello,

A typical reason the thermal cutoff would go out so quickly is because of a poor airflow so the heat is being built up in the dryer instead of being vented out.
What to check is for a blocked/restricted vent,lint built up in the blower housing that is restricting the airflow& or a broken blower wheel that isn't moving the air from the dryer.

Maytag mde9700ayw thermal fuse on heater box blew. replaced it and blew again. will an open safety thermistat cause this


No. A short in the heating element is more likely to blow the thermal fuse. If the thermostat was open, there would be no power applied to the element

Tip

Troubleshooting Element Appliances.


Use a multimeter set to Ohms, then check for continuity from the Phase to the switch, then to the Thermal fuse, < thats a good candidate for replacement, it should read a "Short" across it, OPEN circuit means it has failed. then from Thermal fuse, if OK, to the Element(s), these should have resistance of about 11 - 14 Ohms...from one side to the neutral. When ON, there should be a Resistance reading on the Meter, of up to 14 Ohms measured across the 3 pin plug, Phase to Neutral. would be OK, for a 1000Watt 1KW appliance, it scales up & down.
Essentially with Neutral, as common, the Phase comes in to one side of a Switch, the "Other" side of the switch goes to the Thermal Fuse, the "Other" side of that Fuse, goes to the "Hot" side of the Element. and the "Other" "Cold" side goes to Neutral, common. So essentially with the switch in the ON position, we should get a resistance reading on our meter, measuring from Phase to Neutral. The reading is in accordance with Ohms law. IE: To get the resistance of an appliance, we take the Wattage, & divide it by the Voltage, Taking the answer from that, Amps, we then, divide the Voltage by that result, and we have our Resistance.EG: 1000 Watts, divided by 112Volts = 8.9Amps. Therefore 112Volts divided by 8.9Amps = 12.4 Ohms. That is your resistance or Load, or Element.

Dryer wont heat, replaced thermal cut off and it worked for maybe5 minutes and then it quit heating and now there is no continuity on the new thermal cutoff...I was wondering if there could be a short


The most likely cause of the thermal fuse blowing out again is either a grounded element or a clogged vent. I am assuming you have an electric dryer. If so, unplug the dryer and find the terminals to the element. Remove one of the wires to the terminals and use an ohmmeter/continuity meter to check between the chassis ground and one of the terminals on the element. You should not read any continuity. If you read a short, then the element is grounding out to the chassis. Replace the element.
If the element is okay, then the vent is probably clogged. After replacing your blown thermal fuse with a good thermal fuse, unhook the vent hose off the back of your dryer and run your dryer through a full cycle. If it doesn't blow the fuse, it's your vent and you'll need to clean it out and make sure no birds built a nest in there. If your thermal fuse still blows, replace all of your thermostats.

Good luck!

Dryer drum works but does not heat. Everything else works. I have checked the fuse and I have made sure it is not on air dry.


THERMAL FUSES MAY BE THE CAUSE OF THIS 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. Follow the diagram below to see how to check the continuity of the switch, and look closely at the switch to see a fairly close idea of what you are looking for, ok

OR it could be a thermostat.
Cycle and safety thermostats-read them with an ohm meter. Should show continuity .

or lastly, it might be
the Heat elements-Test heater element with an ohm meter. You will read continuity across a good element ( 8-12 ohms is an average element ).

IF you do not have an OHM-METER, then you can check these issues by following the directions below:

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.

THE DRYER IS NOT PUTTING ANY HEAT OUT.


ften 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.
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.)

The dryer is not heating


Hello there here is a list of things to check
Testing with an ohm meter checking on a dryer....
These are the places that pass voltage to the heater elements on an electric dryer. In order to check a dryer for no heat, here is a list of places to check. Remember to always unplug the appliance before starting testing with an ohm meter. Always remove wires from the part you are testing with an ohm meter ( write down what goes where first before removing any wires ).
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 continuity across 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.

Maytag Dyer model # MDE9700AYW wont heat it blows cold air


Ohm out the thermal fuse, if it is ok, then you can ohm out the heating element, be sure to visually check the element as well becqause it could just be shorted out internally giving you a reading, but first and foremost check your voltages be sure you are getting 240 across the outer plug spades and 120 volts from left to common and right to common, unplug this thing before you get into the element area or you could end up with a smokin fro !

If the heating element read 0 ohms with the wires removed, you have an open heating element, (should be around 10 ohms) replace heating element and you should be ready to rock.
