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.

Dryers run off 220v, and sometimes only one leg of the breaker trips. So you need to flip the breaker all the way off, and then back on. Sometimes the breaker feels off but is not fully reset. Make sure you completely trip it off then back on. Does the dryer light work now? Is there any indication that it's getting some power? If the breaker is fine and your still not getting power, then the next step is to make sure you have power coming to the plug behind the dryer. At this point you should only continue if your comfortable working with electricity. Once you move the dryer you can check the outlet with a meter, or other circuit tester. If you got power here, then you'll need to start checking things on the dryer. you can remove the plate where the cord goes into the dryer and look for loose or burnt wiring there. If that looks ok, then you'll need to start taking the dryer apart; front panel, top, back, etc, as needed to access the wiring and controls. From here you can trace the wiring from the supply to the controls and to the motor, etc. look for anything burn, If nothing looks out of place you can start checking temp sensors, or fusable links. If this is above your head, then stop where your not comfortable and have checked by a service technician.

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
If the dryer is tripping the circuit breaker, it's possible that the circuit breaker itself is malfunctioning. or a wire is loose to breaker.
There could be a loose connection in the outlet. A loose connection in the outlet could consist of wiring that is not functioning and is unable to properly manage current. The current needed by the dryer is being mishandled by the loosely connected outlet and drawing more power from the electrical system, tripping the circuit breaker. check outlet to find out !
Testimonial: "Thank you Carl, there was a quarter in the thermal fuse, off the blower housing, I don't no how it got there but I cleaned the whole machine plugged it back in and it worked. Problem now, as soon as you close the dryer door the dryer goes on weather you use the control panel or not."
Hello Kenneth Joynt - Often when a dryer will not stop running, it is because the unit may have a potential wiring failure, faulty timer, or a communication error with the main control board. 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 issue persists, I would suggest contacting an experienced service technician to determine the precise cause.
