How to troubleshoot your dryer timer

Being faced with a pile of dirty laundry can be frustrating. However, if you need to do laundry and realize that your dryer isn't working, this could take your frustration to another level. Today, we’re taking a closer look at dryer timer issues. The timer on your dryer is important because it prevents overdrying, helps you be energy efficient and lets you know when your clothes dry. 

Unfortunately, many people experience dryer timer issues. These issues can be caused by various reasons, including wear and tear, power supply issues, electrical problems, a faulty timer motor and more.  

If you're experiencing a malfunctioning dryer timer, we're here to help. In this blog, we'll discuss what you should know about dryer timer issues and provide easy-to-follow steps for fixing yours.  

Understanding dryer timer problems

Before you spend too much time pulling apart your electrical components and motor board, it's important to ensure your dryer timer is faulty. Here are some indications that your dryer timer is bad: 

1. Your dryer isn't starting: If you've loaded up your dryer and the power is connected correctly, but it's not responding; this could mean your dryer timer is broken.  
2. The knob isn’t turning: Even if your dryer comes on, you won’t get much accomplished if you can’t set the timer where you need it to be.  
3. There’s visible damage: If you look at the timer knob and realize that something seems broken, then that could be why your timer knob isn’t working. 

Now that we've identified some ways to tell if your dryer timer is defective, let's examine why it may not be working.

What happens when a dryer timer stops advancing?

When a dryer timer stops advancing, it means that the dryer will likely fail to complete its cycle and may not perform properly. The timer is a key component that controls the progression of the drying cycle, so if it malfunctions, the dryer may behave unpredictably or stop entirely. Here's what happens when the timer stops advancing and what might be causing the issue: 

1. The dryer gets stuck on one cycle: If the timer stops advancing, the dryer may get stuck in one part of the cycle (e.g., drying, cooling, or tumbling) without moving on to the next step. This could mean your clothes are either still damp or the dryer is not progressing through the drying stages. 
2. The dryer may not start: In some cases, the dryer might not start at all if the timer doesn’t move. The timer controls the flow of electricity to the dryer’s components, so a non-advancing timer can prevent the dryer from even starting the cycle. 
3. The dryer stops mid-cycle: The dryer may run for a while but stop mid-cycle without completing the drying process. The timer could fail to advance to the next cycle (from drying to cool-down), which might cause the dryer to stop early. 
4. The heating element might not work: In certain dryers, the timer controls not only the timer settings but also the heating element. If the timer doesn't advance, the heating element may stop working at the right time or not activate at all, leaving clothes damp. 
5. The dryer might overheat: If the timer fails to progress, it could overheat if stuck in a particular cycle that causes it to run too long. However, many modern dryers have thermal fuses or sensors to prevent this.
   

DIY troubleshooting for a dryer timer

How to test a dryer timer with a multimeter

Testing a dryer timer with a multimeter involves several steps.  Be sure you are following safety protocol when working with electricity, if you aren't familiar with these protocol it's time to call a repair person. Here’s how you do it.  

1. First, locate the timer in your dryer. It’s usually part of the control panel, often behind the knob or digital interface.  
2. Use a screwdriver to remove the screws and open the control panel. 
3. Look for the timer terminals. To identify which terminals are for continuity testing, refer to the dryer's wiring diagram (usually found on a panel inside the door or in the manual). 
4. Set the multimeter to continuity or resistance mode. 
5. Perform a continuity test. Place one probe of the multimeter on one terminal and the other probe on another terminal, which should be connected when the timer is in a certain position. Turn the timer dial to different cycle settings. For example, in the drying cycle, you should hear a beep or see a reading on the multimeter when the contacts close (indicating continuity). If there is no beep or resistance, the timer's contact points may be faulty and the timer may need to be replaced. 
6. Do a resistance test. If you are using resistance, check for continuity between terminals showing low resistance when the timer is in certain positions and high resistance when the timer is off or in other positions. A high or infinite resistance reading when the contacts should be closed could indicate a defective timer.

If the timer passes the continuity or resistance test and no physical damage is observed, it is likely working fine. However, if it fails to show continuity or the expected resistance at the correct cycle settings, it’s likely faulty and may need to be replaced.

Most common dryer timer problems

When dryer timers fail, the most likely issues include a breakdown of the timer, a broken cycling thermostat or a nonworking heating element. Read on to learn more about how to identify these common problems.

Broken timer motor

A defective timer motor can be stuck in one position and not advance through the drying cycle. If no one notices, the dryer can run a considerably long time. This can affect your dryer and add to your monthly electric or gas bill. While advancing the timer by hand can move the dryer to the next level, this is not always a practical choice and takes much of your attention. To know if the timer motor is causing the issue with your machine, you can follow these steps and test the dryer’s timer motor.  

Testing the timer motor in dryers requires using a multimeter tool. Also called a volt-ohm-milliammeter, this handy device allows homeowners to check a variety of major household appliances for issues. A multimeter measures current, voltage and resistance.

Before testing any electrical appliance, unplug it from the power source. You can even switch off the circuit breaker for added protection. If it’s a gas appliance, turn off the gas to the machine.

After you take those safety measures, remove the control console. The control console is where you find the knobs and buttons that control the dryer’s settings and display. Set the multimeter to RX1, or ohms if RX1 is unavailable, and touch the probes on the timer motor’s terminals. A reading between 2,000 and 3,000 ohms is good. If outside this range, replace the broken timer motor or schedule an appointment with an appliance repair company. 

Broken cycling thermostat

The cycling thermostat is the component that moves the timer through the auto dry cycle and controls the temperature inside the drum of electric and gas dryers. When working correctly, the thermostat activates the heater circuit and maintains and adjusts the temperature inside the dryer drum. When this component fails, the dryer cannot control the temperature and may run at high or low temperatures.

To test the cycling thermostat, make sure the inside of the dryer is at room temperature and unplug it from the power source. Every brand differs, so refer to the machine's owner's manual for instructions on opening the dryer cabinet. Inside, you can find the cycling thermostat near the airflow duct or blower housing. Test the thermostat terminal probes with a multimeter set to RX1 or ohms (resistance). If there is no issue, you will get a reading of zero. Any other result indicates a problem, and the cycling thermostat needs replacement.

Broken heating element

A broken heating element can cause issues with your dryer's timer and prolong drying time. An overflowing lint trap can also slow down drying time. Fortunately, you can test your heating element to determine if it is the issue and needs replacement.  

Once again, unplug the dryer from its power source. If working with a gas dryer, switch the gas valve to the “off” position. Pull the dryer from its location so you can access the back of the machine. With a screwdriver, remove the screws securing the metal coil panel. Inside are wiring and heating element coils. You can find a wiring diagram for your specific dryer in the owner's manual or a quick search on the internet. Set the multimeter to a resistance scale of RX1 and touch the probe to the element. Any reading over zero indicates the element is bad and needs replacement. Use the dryer's model number to find the right heating element for your dryer, or contact a repair company to switch out the heating element for you. 

Repairing or replacing a dryer timer

Having the proper tools is essential when repairing a dryer timer. A multimeter to test electrical continuity, a screwdriver to remove the dryer panel, and pliers to handle wires or electrical connectors are necessary. If the timer motor needs replacing, it's crucial to ensure the new part matches the make and model of the dryer. The replacement timer part can often be purchased from the manufacturer or a third-party supplier. To avoid electrical shock, you'll also want to ensure the dryer is unplugged before beginning the repair.  

If you attempt to repair your dryer timer and there’s no change, simply unplug the dryer for 5-10 minutes to try to reset it.  

If you follow these steps to repair your dryer timer and it still doesn’t work, it may be time to look into replacing it entirely. Here’s a step-by-step guide that can help. 

When to call a professional  

Even if you absolutely love DIY projects, there are some things that you simply won't be able to repair yourself. If fixing your dryer timer becomes dangerous or is more stressful than you can handle, it may be time to call a professional. When looking for a service technician to fix your dryer timer, search for one who's experienced working with different kinds of dryers.

Maintenance tips to keep your dryer timer working properly

To keep your dryer timer working properly and extend its lifespan, here are five maintenance tips: 

1. Clean the lint filter regularly: A clogged lint filter can cause overheating, which may damage the timer and other dryer components. Clean the lint filter after every use to ensure proper airflow and prevent strain on the motor. 
2. Inspect and clean vents: Over time, lint can accumulate in the dryer vent system, restricting airflow. This can cause the dryer to overheat, potentially damaging the timer and motor. Have your vents cleaned at least once a year to maintain optimal airflow and prevent excess heat buildup. 
3. Avoid overloading the dryer: Overloading the dryer can strain the motor and other components, including the timer. To prevent unnecessary wear and tear, load the dryer properly and don't exceed the manufacturer's recommended capacity. 
4. Check the timer knob: Periodically inspect the timer knob for cracks or signs of wear. If it feels loose or difficult to turn, it may cause the timer to malfunction.  
5. Test the timer annually: Use a multimeter to check the timer’s electrical continuity at least once a year. This can help detect any early signs of wear or malfunction, allowing you to address issues before they result in a complete failure.
