If your Kelvinator dryer controls are not working, the most common cause is a worn or stripped knob that no longer engages the switch stem—selector, timer, or control knobs can crack or spin freely and need replacing. After checking and replacing any cracked or loose knobs, inspect the power cord next if the entire display or timer is dead; look for breaks, burn marks, or blackened terminals and replace the cord if you find damage. If the start button is the only control failing and the door switch is working, the thermal fuse may have blown; test it with a multimeter for continuity and replace it if it shows no continuity. These issues are typical when dryer controls are not responding, including a dryer knob not working or the dryer start button not working.

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.

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.
