If your Kelvinator dryer starts on its own or keeps running without you pressing start, the most likely culprits are a failing motor relay, a bad timer, or a faulty control board, listed here in descending order of likelihood. A stuck or shorted motor relay can send power to the motor unexpectedly, and the timer can close contacts at the wrong time if its internal switch fails. If those check out, the main control board can be at fault and may show burned components or shorts when inspected. Less commonly the problem is the touchpad or user control and display board, especially if the start/cancel button is intermittent — that kind of flaky button behavior often points to the control panel rather than the motor or timer. Before replacing parts, test relays and timers with a multimeter and visually inspect circuit boards. Enter your model number on RepairClinic.com to find the exact replacement motor relay, timer, control board, or touchpad that fits your dryer and get step-by-step repair guidance.
01 - Kelvinator Dryer Motor Relay
If the dryer touchpad is working appropriately, it's possible the motor relay is defective. However, this is not that common of a problem. Before replacing the motor relay, check all the more commonly defective parts. If you determine that all of the other components are working properly, you can test the motor relay by using a multimeter and consulting the wiring diagram to help determine if it is malfunctioning.

If the dryer touchpad is working appropriately, it's possible the main control board is defective. However, this is not that common of a problem. Before replacing the board, check all of the more commonly defective parts. If you have determined that all of the other components are working properly, replace the main control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)

If the dryer's start/cancel button is only working intermittently, it's likely the user control and display board is malfunctioning and causing the dryer to start running. A new board will need to be installed to resolve the problem.
06 - Kelvinator Dryer User Control and Display Board
If the dryer's start/cancel button is only working intermittently, it's likely the user control and display board is malfunctioning and causing the dryer to start running. A new board will need to be installed to resolve the problem.
