i am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----

Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.


Heating element
Often 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.


Thermal fuse
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.)


Wiring
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

The thermal cut-off , which is the small t-stat looking piece located at the top of the element housing ( on vertical mount elements ) or the far front of the element housing ( on horizontal mount elements ) , is usually the cause for no heat .

If your ELECTRIC dryer is still running, but does NOT produce heat, the following two links can give you advice on how to troubleshoot an ELECTRIC dryer with a no heat problem:

IMPORTANT: Your problem may or may not be related to a heating element problem as there are numerous factors that can cause a dryer not to heat. The heating element has protection devices that are designed to regulate the heat and internal temperatures. If the dryer overheats the Thermal Cut-Out (TCO) typically will blow BEFORE the heating element. The replacement kit is much cheaper than purchasing a new heating element that may or may not be the problem.


Begin by unplugging the dryer and verifying the voltage at the wall receptacle. You should read 220-240VAC across the two Hot terminals (left and right slots). If the voltage is incorrect, check to make sure you don't have a breaker tripped. Some homes use 2 separate 120VAC breakers to provide power to the receptacle vice using one 240VAC breaker.

If the voltage IS correct, leave the dryer unplugged and remove the cover plate on the terminal block in the back of the dryer (this is where the power cord is installed). Plug the dryer back in and take a voltage reading across the two hot (RED and BLACK) wires at the terminal block. You should read 220-240VAC. If the voltage is good, you have an internal heating problem. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord.

NOTE: If the wires at the terminal block are not color coded, the outer two wires (left and right) are the hot leads. The center conductor is neutral or ground.

The reason a dryer will still run if the input voltage is incorrect, is because the drive motor only uses a portion of the 220 service. The motor runs off 110-120VAC, while the heating circuits require 220-240VAC. So, if you are missing 1/2 your input voltage due to a tripped breaker or bad power cord, your dryer may exhibit these symptoms.

If you determine the problem to be internal, the heating circuits will either be located in the rear of the dryer on the right hand, or under the dryer drum on the right hand side. Usually, an easy way to determine is by the location of the lint screen filter. If the filter is on top of the dryer, the heating circuits are in the back of the dryer. If the lint screen is in the door, the heating circuits are located under the dryer drum.

On a Whirlpool Duet or Kenmore Elite model, the heating circuits are located inside the dryer under the dryer drum on the right hand side. You will need to remove the lower toe panel under the door to access. The toe panel comes off by locating and removing the screws under the bottom front edge of the panel. The Heating Element is located inside a heater box. The Thermal Cut-Out (TCO) will be located on the outside of the heater box on the end opposite the heating element terminals (all the way towards the back of the dryer cabinet). The Hi-Limit Thermostat will be located adjacent to the heating element terminals.

If either the TCO or Hi-Limit Thermostat are determined to be bad, replace BOTH components at the same time. That is why these components are commonly sold as a set. Failure to do so may result in premature failure of any parts you replace.

Replacement parts (if required) may be found at the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The average cost of these components varies, so shop and compare. The first three websites I listed have helpful exploded view parts diagrams that can help you locate and properly identify any parts you may need. The heating components are usually listed under the "Bulkhead" section.


If you have any questions, please post back and let me know. I hope you find this information helpful.


NOTES: If your model number is not listed on some of the websites, use the part numbers from the Sears website and use that as your search criteria. Some model numbers will not reference on some sites, but the part numbers will. If the model number is correct, all your heating circuits are in the BACK of the dryer behind the rear panel. Just UNPLUG the dryer and position the unit so that you may take the rear panel off. With the panel removed, the heating circuits are on the RIGHT-HAND side. Roper is manufactured by Whirlpool, so these instructions do apply.

Sounds like you have a broken drum belt.
If you have to replace your drive belt and if you have a front loading machine.
First you will need to unplug your dryer from the electric.
Remove the front of the machine, this will expose the belt and drum, remove the drum and belt and this will expose the drum rollers, idler arm bracket with pulley, and motor with pulley.
While you have the drum out, I would also recommend that you lubricate the drum rollers at the shaft of the roller with a good grade of machine oil like 3 in One oil. This will save you problem later with the rollers getting noisy, also check your drum rollers for flat spots, if they have flat spots on them this will cause a noise like a thumping type noise. You will need to replace the drum rollers if they have flat spots on them.
If the belt is not broken, then I would check to see if the timer switch is working properly, if not then you may need to replace it.
Good luck,
I hope this helps
