The dryer timer ensures that your laundry is dried perfectly with your appliance. A properly functioning timer ensures that your clothes are not overdried or damp at the end of the cycle. Your dryer's efficiency relies heavily on this small but crucial component. Let's learn how to test timer on dryer to ensure it keeps your laundry routine on track.
What is dryer timer?
It serves as a control mechanism to set the drying duration in a clothes dryer. Users can specify how long their laundry should dry using a mechanical or digital device. The user can select the desired drying time with a knob or digital interface on dryer timers, which can range from a few minutes to an hour or more.
After setting the timer, the dryer's heating element and motor will operate for the specified amount of time, drying the clothes until the timer reaches zero. When the drying cycle is complete, the dryer automatically shuts off. This timer prevents clothes from over-drying, preventing fabric damage and saving energy. In addition, it allows users to tailor their drying times according to their laundry needs, making it an important part of the dryer's functionality.
Tools and Materials Needed For Testing Timer on Dryer
For a smooth and accurate test of your dryer timer, you'll need specific tools and materials. The following are the items you will need:
- Multimeter
- Screwdriver
- Needle nose pliers
How To Test Timer on Dryer With Multimeter
Here's how to test your dryer's timer step-by-step. To ensure a smooth evaluation, follow these simple steps:
"Step By Step"
Step#1. Locate the Timer Panel
Identify the timer panel on your dryer. It is typically located on the dashboard or control console, where you set the drying cycle. "Timed Dry" or "Auto Dry" may be labeled on it.
Step#2. Unplug the Dryer
Unplug the dryer from the electrical outlet before you proceed. Disconnecting the power source ensures you won't be exposed to electrical currents during testing.
Step#3. Remove the Control Panel
To access the timer and its wiring, you may need to remove the control panel or access cover on your dryer. If the panel is held in place by screws or fasteners, remove them carefully with a screwdriver.
Step#4. Identify and Disconnect the Timer Motor
The timer motor is a small cylindrical component connected to the timer. The timer advances through the drying cycle with its help. Disconnect the wires connected to the timer motor. The terminal screws may need to be loosen with your screwdriver.
Step 5. Observe the wiring diagram
The wiring diagram for your dryer timer can be found on the control panel. It is therefore important that you find it and observe it. It will help you understand how your dry timer works. As a result, you will know what contacts need to be closed and opened at what current level.

Step#6. Set Your Multimeter
Set your multimeter to the ohms (Ω) setting. In this setting, you can measure electrical resistance, which is crucial when testing a timer. To test continuity, set the multimeter between 200 and 300 ohms.
Step#7. Test for Continuity
Touch the probes of your multimeter to the terminals of the timer. For information on which terminals to test, refer to the dryer's wiring diagram or manufacturer's documentation. A continuity test involves checking if there is a complete electrical path between these terminals. On the multimeter, a reading of "0" (or close to it) indicates continuity, while an infinite reading indicates an open circuit.
Step#8. Interpret the Multimeter Readings
Note the readings on your multimeter as you test different timer terminals. You can assess the functionality of the timer by looking at these readings. Depending on your dryer's model and make, specific readings may vary, so consult your manufacturer's documentation.
Step#9. Compare the Results
Comparing your multimeter readings with the expected values specified in your dryer's documentation should be your next step after testing all relevant timer terminals. In the case of deviations from these values, a replacement timer may be required. I hope you understand now how to test timer on dryer. But do you know the common issues of dryer timer? Here I will tell you some possible issues.
Common Timer Issues
Testing your dryer's timer requires an understanding of common timer issues. The following are some common problems you may encounter:
Timer Motor Failure: Timer motor failure is one of the most common issues. You will not be able to advance the dryer's timer if the timer motor fails to function properly. You may need to replace the timer motor if your multimeter shows no continuity or erratic readings.
Wiring Issues: The operation of the timer can be disrupted by faulty or damaged wiring. Check the timer's wiring connections for loose or corroded wires. In case you find any, secure or replace them as necessary. Test the wiring harness for continuity with your multimeter as well. It may be necessary to address wiring problems if the readings are inconsistent.

Mechanical Obstructions: Mechanical obstructions within the timer can sometimes affect its performance. Inspect the internal components of the timer for debris, blockages, or damage. To ensure smooth operation, clean or repair the timer as necessary.
Timer Contacts: During a drying cycle, a set of contacts controls various functions. These contacts can wear out or become pitted over time, causing problems.
You can test the continuity of these contacts with your multimeter. The timer contacts may need to be cleaned or replaced if they don't provide a consistent electrical path.
Safety Precautions
When working with electrical appliances, safety should always come first. To prevent accidents and protect yourself, follow these safety precautions before you begin testing your dryer timer.
Protective Gear
Protect yourself from electrical hazards by wearing appropriate safety gear, such as insulated gloves and safety goggles. As you work on your dryer, these items will provide an extra layer of protection.
Unplug the Dryer
Disconnecting the power source is the first step toward safety. While working on your dryer, make sure there is no electricity running through it. As a result, electric shock risks are minimized.
Secure a Stable Workspace
Work on a flat, stable surface. During testing, a well-balanced workspace reduces the risk of accidents or damage to the dryer. Surfaces that are uneven or slippery should be avoided.
Stay Dry
When handling electrical components, make sure your hands are dry. Electric shock can occur when moisture conducts electricity. Before you begin testing, make sure your hands are completely dry.
Tips for Maintenance and Troubleshooting
By maintaining your dryer timer, you can extend its lifespan and prevent potential problems. For both routine maintenance and troubleshooting, here are some tips:
Tip#1 Regular Cleaning
Dust, lint, and debris should not be allowed to accumulate on your dryer timer and control panel. Dirt can impede the proper operation of a timer. Regularly wipe these areas down with a soft, dry cloth.
Tip#2 Lubrication
There are some dryer timers with moving parts that need to be lubricated. Lubrication may be recommended in your dryer's user manual. To ensure smooth movement, use a manufacturer-approved lubricant sparingly.
Tip#3 Inspect Wiring
Visually inspect the wiring connections of the timer periodically. Fix any loose or damaged wires as soon as possible. Replace any frayed or broken wires and tighten any loose connections.
Tip#4 Test Timer Regularly
The timer should be tested periodically even if your dryer is running smoothly. By taking this proactive approach, unexpected breakdowns can be prevented.
