First off what's the brand name and model number?if you have 240 volts to the dryer,and you say you checked all the t-stats and thermal fuse,the only two other things are the motor and the timer or board depending on what model you have,if i were you i would check the t-stats again,more so the ones on the heater,set your meter to 20k ohms with the dryer unplugged go to the part you want to check,pull off at least one of the wires or both if you want,touch the leads one on each side of the part where the wires connect to it,if you see 1 the part is bad or open,if you see anything else but 1 the part is good or closed.if you need more help send the brand name and model number,also there's a belt switch,if the belt breaks the dryer won't run if your model has this check that too,more so if it's an older ge,

SOURCE: clothes dryer

These t'stats are in series with the element monitoring temp's at different locations and are rated for different temperatures. When they are "satisfied", they close the circuit and allow power to the element. When dis-satisfied they "open" the circuit, thereby killing power to the element. If you are reading infinity on one or both of these t'stats when they are room temp, it indicates a failed component and must be replaced. Don't forget to OHM out your element, too. If you read anything other than infinite resistance, it's OK.

SOURCE: Whirlpool Dryer not heating

The motor has to be running for voltage to exit the motor going to the heater. With the back off the dryer and the motor running you should read 220 volts at the heater if all safetys and thermostats are good.
There is a thermal cut out relay on the heat canister. It must read continuity also.
Remember you must remove at least one wire from each component being tested to get a true open or closed reading. If a wire is left connected you get a false reading.
The heating element could be broken and part of the heater wire touching the canister. This would cause a continuity reading and still no heat.
Finally, yes,the centrifugal switch in the motor could be bad and not sending power to the heater on the red wire.

Testimonial: "I did determine it to be the cetrepetal switch..specifically the slide for the weights was heavily gummed up with dryer belt dust. It works now."

SOURCE: Dryer not heating

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes 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 differentthings that can go wrong causing the dryer not to heat. check out this electric no heat tip...

My Kenmore 400 turns on, tumbles but does not heat up. What could be the problem

I am assuming this is an electric only (not gas) dryer, as I cannot find any tech data on your specific model. This is a general troubleshooting guide for heat issues with electric dryers, going from the most common to least common solutions:

**Standard disclaimer--voltages in a dryer (or any AC connected appliance) are high enough to kill you. If you don't know what you are doing, or have any difficulty understanding what I am saying....STOP and call a professional.

With that being said....

1. Test the power supply feeding the dryer and make sure that both 120 volt legs are getting power in reference to the neutral wire. Check between them (red wire to black wire) and check for 240 volt power. A bad breaker or partially failed 240 volt circuit may still provide power for the motor (which only uses one 120 volt leg) but not the heating element, which uses both 120 volt legs to make 240 volts for the heating element. Be sure to check both the receptacle and the terminals where the cord attaches to the dryer.

2. With the dryer unplugged, and the heating element disconnected, check for continuity between the heating element terminals. You may also be able to visualize the heating element coils if you remove it from the dryer. Most elements are held in place by one small sheet metal type screw, in case you need to remove it.

3. Check for continuity on the thermostat and thermal cutoff switch on the dryer. These parts usually are about 1.5" across and are screwed into the metal housing for the heating element. When the dryer is cool, both of these parts should have continuity. Remember to remove the wires from at least one of the terminals before checking continuity. These parts may look similar. If you have a defective one, google the part number stamped into the side of the part to determine which one is which. They are NOT interchangeable.

4. If all of this checks out ok, you will need to check for power coming from the timer to the heating assembly with the power on. The thermostat, thermal cutoff and heating element are typically wired in series. The two wires coming from the timer area down to the heater assembly should have 240 volts between them when the dryer is powered on and in a heating cycle. Once again BE CAREFUL IF YOU DECIDE TO DO THIS. IF IN DOUBT, READ THE WARNING ABOVE.

Your dryer may also have a switch to control the heat intensity, independent of the timer. If it does, check that as well.

Good luck, and I hope this helps!

Put new thermal limiting switch, thermal fuse and heating element in my whirlpool estate elec. dryer. it will not get hot still is there something i,m missing?

their are several possibilities

1) check breaker and or fuse to be supplying 240 volts to the dryer,even though the breaker seems to be on a internal burned out breaker will appear to be set but 240 vac not at dryer

2) check were the cord connects to back of dryer that one on the legs hasnt burnt and only 120 vac to dryer instead or required 240 vac

3)depending on your model i dont know if you have a timer or computer control but it isn't sending power to the element

4) the motor switch could be defective, all dryers are required by law to have a built in safety that assures the dryer will not heat when it isn't running to do that all dryers have a switch built into the motor that will only send power to the element once its running

5) in addation to the high limit t-stat and thermal fuse all dryers (depending on model) have a cycling t-stat or thermistor that controls the normal operating temp (the high limit and thermal fuse only come in to play when a dryer overheats) that could be defective

Electric dryer spins no heat, replaced heater element and high limit thermostat, tested thermal fuse and it does have 0 ohms, thermistor reads ~50 ohms.

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

Lg rd3500 147* not working what doooooooo

Well first of all, I checked the manual, and this is not in there.
I was drying my clothes and it stopped working. The lights in the ring that choose what kind of a load you want...well the first three are blinking. The second two are not. It will not let me choose a load or drying time, and if I press start, the thing inside goes around once and then stops. I looked in the filter basket and there's nothing in there and I wiped the sheet off.
Now the lights aren't blinking and I can choose an option, but it only goes for like a minute and then stops
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. LEG: - 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 check instead.
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.

please comment on these solution by saying how helpful.mean vote.

We have a 5 year old Roper electric dryer that started to fail in heating the clothes. I've checked the electric plug at the wall, and have 240 volts. I've checked the thermal fuse, and the continuity is...

You can test the stats they should read short circuit/ normally closed, you could short them out for 10 secs to check not good idea to leave permanantly as would cause safety issue element if one section two wires plus an earth to it should read about 30 0dd ohms

CHECK FOR 240 VOLTS AT DRYER ELEMENT WITH DRYER
RUNNING IN HEAT CYCLE. IF NO VOLTAGE, CHECK WALL
OUTLET FOR 240 VOLTS BETWEEN LEFT AND RIGHT SLOTS IN RECEPTACLE. A DRYER WILL RUN ON 120 VOLTS TO
GROUND BUT WILL NOT HEAT IF 240 VOLTS IS NOT PRESENT. IF THERE IS 240 AT THE OUTLET, START TRACING THROUGH THE HEATER CIRCUIT. LOOK FOR A FAILED THERMOSTAT OR THERMAL FUSE NEAR THE HEATER OR EXHAUST OUTLET. CHECK THEM WITH A CONTINUITY TEST WITH DRYER UNPLUGGED, OR A VOLTAGE CHECK WITH A HOT CIRCUIT.
