If your Gibson dryer controls are unresponsive or the start button is not working, the most likely culprits are worn or cracked control knobs that slip on the selector, timer, or switch stems. A knob that spins without turning the switch is an easy visual fix: replace the stripped or broken knob and the control should respond again. If the entire display or timer is dead, inspect the dryer power cord for breaks, exposed wires, or blackened terminals and replace the cord if it shows damage. If only the start button fails and the door switch is confirmed good, a blown thermal fuse is a common cause; use a multimeter to check continuity and replace the fuse if it has opened. These checks cover the most likely reasons your dryer controls are not working, whether the knob is not working or the dryer controls are not responding at all.

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 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.
