What Causes a Washing Machine Timer to Fail?

If your washing machine’s timer is not advancing through the cycle, it can be a frustrating and perplexing problem. However, there are a few common culprits that can cause a washer timer to malfunction. Understanding these potential issues can help you troubleshoot and potentially fix the problem yourself.

Defective Timer Motor

One of the most common reasons for a washer timer not advancing is a faulty timer motor. The timer motor is responsible for turning the timer mechanism and advancing the cycle. If the motor is defective or has failed, it will prevent the timer from moving forward.

Stuck Control Contacts

Another potential cause of a timer that won’t advance is stuck control contacts. Inside the timer mechanism, there are a series of contacts that control the various cycles and functions of the washer. If these contacts become stuck in the open position, it can prevent the timer from advancing to the next cycle.

Defective Drive Gears

The timer mechanism is driven by a series of gears that turn the timer dial. If these gears become worn, damaged, or defective, it can cause the timer to stick or not advance properly. This is less common than motor or contact issues, but it is still a possible cause of a malfunctioning timer.

To troubleshoot the problem, you can try unplugging the timer’s wiring harness and checking for continuity through the motor contacts. With the timer set to any position other than off, use a multimeter to check for continuity between the terminals that supply power to the motor. If you don’t get a reading, it indicates a problem with the motor or the timer itself.

If you suspect a faulty timer motor or other internal timer issues, it’s best to consult with a professional appliance repair technician. They can properly diagnose the problem and recommend the best course of action, whether that’s a repair or replacement of the timer mechanism.
