Roper Dryer controls don't work
If your Roper dryer controls are not working, start by checking the control knobs—selector, timer and mode knobs are the most common failure. Knobs that are cracked or stripped simply slip on the switch or timer stem and will not engage the control, so replacing a worn knob often restores function. If the entire display or timer has gone dead, inspect the power cord next for breaks, burn marks or blackened terminals and replace the cord if the insulation or connections are damaged. If only the start button is unresponsive and the door switch checks out, the thermal fuse is a likely culprit; test it with a multimeter for continuity and replace a blown fuse. These fixes are straightforward for a confident DIYer and repair techs alike, but always unplug the dryer before you work on it. Enter your model number on RepairClinic.com to find the exact replacement dryer control knob, power cord, thermal fuse or other part that fits your machine and to get parts diagrams and step-by-step repair guidance.
01 - Roper Dryer Power Cord
If the whole dryer display or timer is not working, the dryer's power cord could the source of the problem. Inspect the cord for any breaks or burn marks near the terminals. If the terminals appear blackened or wires are exposed through the cord's insulation, you should replace the power cord with a new one.

06 - Roper Dryer Timer
If the whole dryer display or timer is not working, it's likely the timer itself is defective. However, this is not that common of a problem. Before replacing the timer, check all the more commonly defective parts. If you determine that all of the other components are working properly, test the timer by using a multimeter and consulting the wiring diagram. If the timer is defective, replace it.
Common
07 - Roper Dryer Thermal Fuse
If just the start button is malfunctioning and you've confirmed the door switch is working properly, then it's possible the thermal fuse has blown. You can use a multimeter to test the fuse for electrical continuity. If the thermal fuse has no continuity, you'll know it has blown and will need to be replaced.
