The first step in troubleshooting would be to unplug the dryer and remove the cover on the terminal block. This is where the dryer power cord is installed. Plug the dryer back in and then take a voltage reading across the two hot (RED and BLACK) wires on the AC Voltage scale. You should read about 220-240VAC if good. If the voltage is bad at the terminal block, unplug the dryer again and check the wall receptacle across the LEFT and RIGHT slots. If good at the receptacle, but bad at the terminal block, you have a bad power cord. If bad in both places, you have an electrical problem with the receptacle of distribution source.

Now...barring a defective drive motor, improper source voltage at the wall receptacle, or defective power cord, the most common cause of a dryer that will not run is a blown Thermal Fuse.

The Thermal Fuse is located on the air blower fan housing in the back of the dryer. It is a small white plastic component with two wires attached to it. To access, simply remove the back panel of the dryer. The Thermal Fuse will be located on the blower fan housing on the lower left hand side of the dryer. Make sure the dryer is unplugged and disconnect the wires before making any resistance checks. The fuse should read about zero ohms if good. If bad, replace it. You can purchase replacements on line at searspartsdirect.com, appliancepartspros.com, or repairclinic.com. Just use your model number for your search criteria. The Thermal Fuse is listed under the "Bulkhead" heading as item number 8.

NOTE: If the Thermal Fuse is blown, it usually blows for a reason. Verify all your ventilation ducting and blower fan assembly is clear of any clogs. Failure to do so, will result in repeated failures of any components you may replace.

If you have any questions, please let me know. I hope this helps you.

Roper electric dryer wont start


Electric dryer no start does nothing

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.

CHECK THERMAL SHUT OFF THERMOSTAT USUALLY LOCATED ON THE BLOWER. for OHMS or resistance with a meter. Should show a closed circuit. Ohms WHEN THIS FUSE BLOWS IT WILL SHUT DOWN EVERYTHING.

NEXT Test the PUSH start switch with meter for OHMS. Should show OHMS when pushed in or on start, and no ohms or infinity when in off position.

If you hear a humming/clicking sound from motor area you more than likely have a bad motor.
Try this test out to see if u have weak windings or relay/capacitor on motor.
Open the dryer door and turn by hand the drum while machine is on ON position. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings

Another thing to check is the belt safety switch. With a multi meter.
Especially if u just replaced the belt. The belt safety switch is attached to the Tensioner and motor. IT LOOKS LIKE A DOOR SWITCH SOMEWHAT a little black pc of plastic with 2 prongs going into it. Sits at bottom of motor. Under the Tensioner. Attach meter clips to the 2 prongs on switch, Then when the little white push button is pressed in it should show continuity and none when released.

Lastly check ur DOOR SWITCH for continuity with a meter when the button is pushed in the (on/Door closed position,) it may have gone bad.

What to Test When Whirlpool or Kenmore Dryer Won Start or Run

Dryer continuously runs- and starts when you close door


ok, make sure to test the door pressure switch for its operational value. if the switch is in good condition and it doesn't appear to be faulty and, the wires are connected firmly, replace the timer/control. In most cases,your door switch will need to be replaced. these switches will develop shorts overtime.

Roper dryer won't shut off


The timer motor isn't moving the timer. You'll need to replace the timer. Turning the timer **** to off should stop the machine.
Exception: If the shutting the door automatically starts the motor, then the start switch/relay is probably shorted.
