Dryer has power but doesn't spin or heat up

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 silly, but because it's an electric dryer, it's run on a 220 line. Double check your breaker box to make sure both breakers are in the correct position. If only one breaker is in the correct position, you'll have electrical power, but the drum won't spin.

Does it do this in all setting on the dial, normal,heavy ,delicate?

see this causes and fix it. God bless you
Check to see whether there's power getting to the dryer. Is it plugged in? If you plug something else into the outlet, does it work? If not, check for a blown fuse or tripped circuit breaker.

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.

Thermal Fuse / Thermal Cut out

On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel or behind the front panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing or is sometimes round and made of metal and plastic.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse this is the most common reason for blowing the fuse. (You can't re-set this type of fuse.)

Wiring

Often the main wiring connection from the house, at the dryer, burns and the connection breaks. In 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.

If the lid switch is defective, your washer can't spin and may not function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washer to get to the switch. If it's defective, you need to replace it. To determine if the lid switch has failed, watch the part testing video at the bottom of this page. Some machines have a special lid-switch fuse near the lid switch, inside the control panel. If this fuse blows, the unit won't fill with water until you replace the fuse

Most of your fuses for a Frigidaire dryer are upper right hand side of the rear bulkhead. Here is a westinghouse dryer video I made In the video I look for failed components and show the various parts, explain their function, and location.

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.

probably the belt snapped that spins the drum

Is the thermostat defective?

Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)
