Dryer turns, but why doesn't it heat?

Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

Sounds like you need a new blower wheel. You would need to remove the drum and front panel.I think it is a reverse thread on blower wheel.

what stopped? Does it not Spin? if so it could need a new motor. If it spins but doesn't heat up. it could just be a heat sensor in the back that needs to be replaced or a heating element. if nothing happens at all it could be the start button needs to be replaced. Turn the dryer around and open up the top back panel. should be about 6 screws. inside there will be a diagram on the schematics of the dryer.

Hope this helps.

depending on which model roper dryer it can be a thermal fuse,high-limit thermostat,cycling switch,burned off wire in control panel,check each side of the heating element to ground and find 125 v.a.c. then on the side of the element that has low or no voltage on it to ground start at the element and back track the components leading to the dead leg on the element till you find 125 vac to ground and replace or repair component or wire,then you should get 240 to 250vac across heating element terminals

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...

more than likely the heating element is not working. if there's no heat at all, this is probably the culprit. you have to gain access to the heating element to test it for continuity. no continuity=bad element=needs to be replaced. if you can get this far, then it's easy to change it out.

hello matt.... the most common cause of no heat is a burned out heating element. Replace it and you should have heat again. Joe

sounds like a bad cycle timer switch

If you here motor running, you have a broken belt. Give brand and model and I can help you change it.
