Dryer turns on but won't heat up or tumble

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

Rotating blinking lights in the display is probably an indication that the Wrinkle Prevent option has been selected. Wrinkle Prevent will continue to tumble the dryer without heat after the cycle has ended to help prevent wrinkles from setting in. When this option is selected by pressing the Wrinkle Prevent button on the control panel, the display will count down the estimated cycle time; when the cycle ends, the display will show lights blinking in a circular (or actually rectangular) motion.

To deactivate, simply press the Wrinkle Prevent button again so the light is not illuminated.

Hi margaretc920 - Often when a dryer turns but will not heat, it is because either a fuse from the fuse box is blown or the switches on the breaker tripped, depending on your house. If your house uses fuses, there are two house fuses that supply voltage to the dryer circuit in your fuse box. If one of the two fuses is blown, the unit may turn but will not heat. Check and replace fuse in fuse box if necessary. However, if the house has circuit breakers, there may be two breakers with switches that supply voltage to the dryer and if one is tripped the unit as well will experience this issue. The heater of a dryer requires 220 to 240 volts to operate. Try resetting the unit by either unplugging it or flipping the household breaker to the off position. Wait approximately two minutes, turn on the dryer and select a normal cycle. If the issue persists, it could also potentially mean a number of other things: defective cord, wiring, control board or door switch. I would personally contact a professional to accurately diagnose the dryer to determine the root cause to reduce the risk of unnecessary parts.

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 outthis electric no heat tip...

Your machine may have a feature called wrinkle guard or wrinkle shield, which basically keeps tumbling the clothes without heat to prevent wrinkles from setting in. Turn that feature off and see if that does the trick.

sound like heater or stat call them out.

try a belt

go into service mode and reset

to do this move to delicates turn on dryer and keep
pressed down cancel button for about ten seconds release
then all lights should flash when you press cancel again machine will go through test mode , then just turn machine off
it is now reset, this worked for min a drcs68w
