Before beginning work on any electrical appliance, for your personal safety, be certain to disconnect it from its power source.
This troubleshooting guide applies to many different models of electrical dryers but in particular to Whirlpool, Kenmore, and Roper dryers.
Every now and then, appliance repair companies get calls for dryers where the timer seems to be stuck in one position. Because the dryer is not going through a complete cycle, your clothes may not be as dry as you expect.
The timer may not advance past the starting phase with a No Start and No Run problem.
You may have the dryer set to a timed dry cycle, maybe an hour. But when you return to check on the dryer’s progress you notice that in spite of the fact that the dryer seems to be working the timer has not advanced.
This is starting to sound like a timer that needs to be replaced which is exactly what we are going to be discussing.
- ¼ inch nut driver
- Flathead screwdriver
How to Access and Remove the Timer
- Using the ¼ inch nut driver, remove the screws that hold on the rear top panel.
- Locate the timer, which in most cases is to the right.
- Test the timer’s continuity with a multimeter.
- Remove the wire harnesses that are plugged into the timer.
- Using the two probes on the multimeter, you are going to check continuity between three separate connections.
- On each harness or connector, there is a corresponding letter for each connection. Find the letters and test as follows. T to X; C to B; C to A; and T to S1
- When the dryer is running the circuits should be closed. If any of the previous combinations tests open, the timer has failed and should be replaced.
- Carefully remove any remaining connectors from the timer. Don’t worry about remembering how or where they go as each connection is keyed individually to match and will only fit one way.
- Use the flathead screwdriver to pry open a tab that holds a power source harness to the rear of the timer.
- Remove the timer knob, the two screws that hold the timer in place, and pull the old timer out.
- Replace the old timer with the new timer.
- Replace all other connectors and wire harnesses.
After installing the new timer, replace the rear panel. Note the small lip on the bottom of the rear panel and carefully slide it in place before reattaching its screws.
If you had to remove the dryer vent hose from the dryer vent, follow these easy tips to reinstall.
- Tilt the dryer on its face to access vent hole at the bottom of the rear of the dryer.
- Release the hose clamp on the vent hose.
- Place the hose on the vent hole and tighten the clamp.
- Tilt the dryer back in place, plug it in, and run a test load to see if the timer is working as it should.
