ByKurt Vonnegut Updated

Why Wont My Dryer Start?

If your dryer won’t start, there are a few potential causes to consider.

First, check the start switch using a VOM set to the RX1 scale.

If the switch reads zero, it is working fine.

If it shows a high reading, the switch is faulty and should be replaced.

Another possibility is a faulty thermostat, which can be tested using a VOM.

A reading of zero indicates a working thermostat, while a high reading means it needs to be replaced.

Additionally, the dryer timer could be the issue.

To test it, use a VOM and disconnect one of the power leads while the timer is set to the NORMAL DRY setting.

If the meter reads zero, the timer is working.

Otherwise, it needs to be replaced.

Replacing the timer involves disconnecting the old wires one at a time, connecting each corresponding new wire as you work.

Did You Know?

1. The very first patent for a hand-operated clothes dryer was issued in 1800, long before electric dryers came into existence. This early version consisted of a wooden frame with racks on which clothes could be hung to dry.

2. The most common reason for a dryer not starting is a blown thermal fuse. This small device is designed to protect the dryer from overheating, and if it blows, it will cut off the power supply to prevent any potential fire hazards.

3. Did you know that certain types of fabric softeners can actually cause a film to build up on the moisture sensor of your dryer? This can lead to inaccurate readings, causing your dryer to shut off prematurely or not start at all. It’s best to clean the moisture sensor regularly to ensure proper functionality.

4. In the early days of mechanical clothes dryers, before the invention of electric ones, some machines were fueled by gas or even wood. These contraptions were often placed in dedicated laundry rooms or basements, but extreme caution was required to prevent fires.

5. Dryers have evolved a great deal over time, but the invention of the automatic clothes dryer, as we know it today, can be attributed to J. Ross Moore. In 1938, he introduced the first fully automatic dryer that combined heat, airflow, and tumbling to dry clothes efficiently and safely. This invention revolutionized how we dry our clothes at home.

Detach any wires connected to it and set the VOM to the RX1 scale. Touch the probes to the terminals of the start switch. If the meter reads zero, the switch is functioning correctly. However, if the needle jumps to a high reading, the start switch is faulty and should be replaced with a new one.

2. Testing And Replacing Thermostats

Thermostats are responsible for regulating the temperature inside the dryer. When these components become stuck or stop functioning properly, it can result in a dryer that doesn’t start. Testing and replacing thermostats require caution, as you’ll be working with live electrical components.

Important note: As a precautionary measure, remember to disconnect the dryer from the power source before proceeding with any repairs.

To test and replace thermostats, follow these steps:

  1. Locate the thermostat, which is usually found near the heating element or blower housing.
  2. Disconnect any wires connected to the thermostat.
  3. Set your VOM (Volt-Ohm-Meter) to the RX1 scale.
  4. Touch the probes of the VOM to the terminals of the thermostat.
  5. If the meter reads zero, the thermostat is functioning correctly.
  6. However, if the needle jumps to a high reading, it indicates a faulty thermostat that needs to be replaced.

Remember to handle the electrical components with care and ensure your safety throughout the process.

3. Understanding And Repairing Dryer Timers

The dryer timer is a crucial component located in the back of the control panel. It plays a significant role in controlling various functions of the dryer including the drying time, electricity flow to the heating element, and power flow to the timer motor and drum motor.

Dryer timers are equipped with synchronous motors that drive the timer mechanism, ensuring accurate timing for the drying process.

However, over time, the contact part of the timer can become dirty or misaligned, leading to a malfunctioning dryer. In such cases, it is recommended to seek professional help for timer motor repairs.

Alternatively, if you are confident, you can easily replace a faulty timer yourself, avoiding unnecessary expenses.

To summarize:

  • The dryer timer is a vital component that controls various functions of the dryer.
  • Synchronous motors are used in dryer timers to drive the timer mechanism.
  • If the timer becomes dirty or misaligned, it can cause the dryer to malfunction.
  • Seek professional help for timer motor repairs.
  • Alternatively, you can replace a faulty timer yourself to save on expenses.

Frequently Asked Questions

What would cause my dryer not to start?

In addition to a malfunctioning or improperly latched door, another possible cause for a dryer not starting could be a faulty thermal fuse. The thermal fuse acts as a safety device to prevent the dryer from overheating. If it senses excessive heat, it will blow and cut off power to the dryer motor. Therefore, if the thermal fuse is blown, the dryer won’t start until the fuse is replaced.

When I press the start button on my dryer nothing happens?

If pressing the start button on your dryer does not trigger any response, one possible cause could be a faulty door switch. The door switch is responsible for signaling the dryer that the door is securely closed, allowing it to start. If the switch is malfunctioning, the dryer may not receive this signal and therefore will not initiate any actions. In order to resolve this issue, inspect the door switch to ensure it is properly aligned and functioning correctly. If necessary, replacing the switch should resolve the problem and allow your dryer to start functioning again.
