Dryer problems occur at the worst moment possible. Call it the Murphy Law! This usually happens when you have a huge load of laundry. In my case, my dryer won’t start but has power. This happened on the weekend when I usually do my cleaning. If your Whirlpool dryer won’t start, the first thought is to call a repairman. I opted against that and tried some DIY troubleshooting. And, surprisingly, I was able to fix my dryer.

So, if your dryer won’t start, what do you do? There are several common dryer issues that could make it not start. In most cases, a dryer won’t start after a power outage. This can be due to a blown thermal fuse and power problems. It can also happen because of a defective door switch, start switch, drive motor, main control board, timer, and belt switch.

The first thing is to identify why the dryer won’t start and troubleshoot the specific issue. Let’s dive in and see what to do if your Maytag dryer won’t start or just any dryer.

Major Problems Why Dryer Wont Start And Step-By-Step Solution

Major Problems Why Dryer Wont Start
  1. Power to the dryer
  2. Defective door switch
  3. Blown thermal fuse
  4. Defective start switch
  5. Defective timer
  6. Defective thermostat
  7. A malfunctioning main control board

1. Power To The Dryer

If your dryer is on but won’t start, you need to check if there is power. In most cases, the power coming into your dryer might be the issue. Is the power strip working? To check if there is power getting into the dryer, unplug it and plug a different appliance. Is the appliance turning on? If not, then there are power issues.

Solution

  1. First, make sure the dryer is tightly plugged into the power outlet.
  2. Next, use a multimeter to test for power on the outlet. Make sure the circuit breakers and fuses are working properly.
  3. In case of damaged circuit breakers, consider replacing them.

2. Defective door switch

A door switch plays a crucial role in starting and stopping the tumbling process. When closing the door, you need to hear a clicking sound. A clicking sound is a clear indication the door switch is activating. If the door switch clicks, then the door switch is functioning well, and the dryer should start.

If there is no clicking sound, the door switch is defective and the dryer won’t start. However, what if the dryer clicks but won’t start? If that’s the case, you need to make sure the door locks tightly.

Solution

  1. Before starting any repairs, disconnect the dryer by plugging it off
  2. Ensure there is connectivity between the door switch and the motherboard. This is done by checking the wires connecting the door switch and the motherboard.
  3. If the wire is cut out, make sure you remove it and replace it. Use a multimeter to check for continuity. If there are infinite readings, then consider replacing the door switch altogether. You can order a door switch replacement pack.
  4. Remember, a Kenmore dryer won’t start even when it has power as long as the door switch is broken. This also applies to dryer brands like Samsung and Ge.

Once you have a new door switch in place, your dryer should start without any problems.

3. Blown thermal fuse

A thermal fuse remains one of the most overlooked items in a dryer. In most dryers, the thermal fuse is set in the exhaust duct on the rear panel. A whirlpool duet dryer won’t start if the thermal fuse trips. In some instances, the dryer might start but won’t heat. A thermal fuse plays a crucial role in dryers maintaining safe and consistent temperatures. If the dryer won’t start and smells like burning, then check the thermal fuse right away.

 Solution

First, it is not possible to reset a blown thermal fuse. If the thermal fuse is blown, then you need to replace it right away. One indication to show a blown thermal fuse is when a Samsung dryer won’t start, but the lights are on. Check the lights for continuity using a multimeter before checking the thermal fuse.

Use your dryer manual to gain access to the thermal fuse. Carefully, follow the movement of the wires from the dryer components to the thermal fuse. If there are signs of damage, consider replacing the thermal fuse. Make sure the new thermal fuse fits within the same exact port.

4. Defective start switch

An Amana dryer won’t start, or just any dryer when the start switch is defective. A start switch connects to the start button and helps turn on the dryer. So, if your LG dryer won’t start or the Whirlpool dryer, check the start switch.  How do you fix a defective start switch?

Solution

To fix a defective start switch, remove the knob from the start switch. Open the control panel and check the wiring on the switch. Use a multimeter to test for connectivity at both ends of the switch. This is done by clipping the probes on the terminals of the switch. If the start switch is faulty, you need to replace it. Get a new dryer start switch and follow the installation guides. Once the new switch is in place, the dryer should start.

5. Defective timer

Is your dryer getting power but won’t start? The fisher and Paykel dryer won’t start if there is a timer problem. The same applies to dryer models like Whirlpool, GE, and Samsung. A defective timer can prevent your dryer from starting. However, there are a few cases where the dryer won’t start,t but the timer works.

You need to inspect the dryer timer and ensure it’s functioning properly. Electric dryers timers conveniently allow owners to set the exact time to start drying laundry and for how long. When the feature is damaged, most dryers won’t start.

Solution

  1. Get a multimeter and set it to RX100 for testing the timer
  2. Next, connect the multimeter to leads from the timer motor
  3. You want to check the reading on the multimeter
  4. The timer is defective if you receive a reading of infinity
  5. If the timer is faulty, get a new timer and replace the damaged one
  6. Set your timer conveniently and connect the dryer

6. Defective thermostat

A dryer thermostat can be found on the back panel of dryer models. If the dryer thermostat is damaged, the dryer might start but won’t heat. A bad thermostat usually leads to a loss of temperature control. In a case of a failed thermostat, the dryer might indicate error codes of F-22, E1, or F-23.

There are several causes of a defective dryer thermostat. First, a frayed wire can affect the thermostat. Secondly, a blown thermal fuse too close to the thermostat can affect the thermostat’s functionality.

Solution

  1. Test your dryer thermostat using a multimeter for continuity
  2. The test should give readings of zero or infinity
  3. If the multimeter provides readings of infinity, then consider replacing the thermostat
  4. Buy a new thermostat and follow manual directions to replace it
  5. Open the back panel to access the old thermostat
  6. As always, make sure the dryer is disconnected from the power socket
  7. Remove the wires connecting to the old thermostat and place the new thermostat in place
  8. Fix the wires back and work backward
  9. Connect the dryer and start it
  10. It should work and heat clothes at the right temperatures

7. Malfunctioning main control board

The main control board is the foundation of every dryer. In most cases, a dryer turns on but won’t start if the control board is defective. A dryer light flashing that won’t start is an indication of a damaged component on the main control board. This happens when the dryer relay switch on the control board burns out.

It can also happen when the switch is stuck on and the dryer says sensing but won’t start. In most cases, there is a damaged component on the main control board. So how do you fix a damaged main control board?

Solution

If an Inglis dryer won’t start because of a defective main control board, the only solution is to replace the control board. In the dryer DIY manual, there is a guide that shows the control board location and how to replace it. While the board access might vary depending on the dryer model, the replacement process is the same if a Ge dryer won’t start or an Electrolux dryer won’t start. Follow the steps below to replace your main control board:

  1. Disconnect power by unplugging
  2. Remove the cover on the main electronic control board using a screwdriver
  3. Detach wires that connect to the main control board
  4. Take out the old control board using a slot screwdriver
  5. Install the new control board
  6. Fix the wires to their ports
  7. Reinstall the dryer cover
  8. Restore power and connect the dryer

The dryer should turn on and work normally when you have a new control board in place. While electric control boards can be repaired, getting a new one is always recommended.
