Your clothes dryer is an important appliance, and it can be very stressful when it is not operating correctly.
Sometimes, a problem that occurs is the dryer won’t turn off unless you open the door.
Have you dealt with this issue? Dryer even will start by itself when the power is OFF once you will close the door.
Yet, don’t stress, there are some things you can do to troubleshoot. The good news is that this problem is generally caused by one of two things, but it’s not always easy to fix it.
Let’s take a look at what may be causing the problem (there are not many of them), and how to fix it.
- Motor Relay on the control board stuck in ON position
- Wrinkle Prevent is enabled
- Push Start button relay stuck (on old dryer models)
Wrinkle Prevent is Enabled (Not Common)
There’s nothing worse than removing clothing from the dryer that is wrinkled.
This usually occurs when you are unable to immediately remove your clothing from the dryer after the cycle has stopped.
While this issue can also occur when you leave clothes in the washing machine too long as well, the dryer usually takes care of this problem.
To make it easier for busy people, dryer manufactures have added options that prevent wrinkles. These cycles usually work by kicking on and off.
The original drying cycle will end, and then the dryer will shut off. After a certain amount of time, the unit will turn back on and tumble the clothes for a set amount of time.
The dryer will do this until you stop the cycle and remove the clothing.
This option can cause the dryer to continue running until the door has opened.
So, if you are experiencing an issue with the dryer not turning off until the door opens, check if this option is turned on.
If you do not want this problem in the future, simply disable the option and it will stop.
The Motor Relay on the Control Board is Stuck (Most Common)
If you find that wrinkle prevent is already disabled, the other common problem is the motor relay on the control board is stuck or has shorted out.
When the relay is stuck in the “ON” position, it ignores the signal from the control board and every time when you shut the door, power flows to the motor through the door switch.
If you suspect this is the problem, here’s how to troubleshoot it:
Disconnect the power from the dryer and pull it forward so you can access the rear
Remove the screws in the back that hold the control panel in place
Flip the control panel up so you can see the control board
The relay switch should be on the lower right corner of the board
Is the relay melted? Or do you see black marks on the metal panel?
Check the back of the board for a burnt pin
If you find any black marks or burnt pins, then the relay switch is your problem. You have a few options on how to fix this.
Do you know how to use a soldering iron? If so, replacing the relay is fairly easy. See the next set of steps on how to do this.
If you aren’t comfortable with a soldering iron, you’ll want to skip the next set of steps and replace the entire control board. See below.
Replacing the Burnt Relay
Remove the control board from the dryer, and unplug all wires and connectors that are attached to it.
You may want to take a photo of where these wires and connectors go, so you can reassemble the correct way.
Use a soldering iron to heat the pins on the back of the bad relay up.
Melt the solder and lightly pry the relay off the circuit board at the same time.
Clean up the burn mark area on the back of the board, so the new relay will go through.
Carefully heat the pins using the soldering iron, and touch the solder onto it.
Fit the board back into the plastic housing
Reconnect the protective cover and plug the wiring back in
Plug the control panel back in
Slide the control panel back onto the lock in the catches, and replace the screws.
Plug your dryer in and complete a test cycle
Your unit should run like normal now.
Replacing the Control Board
Turn of all power to your dryer. If it’s a gas unit, also turn the gas off.
Slide the dryer away from the wall, and remove all screws securing the top panel to the frame.
Release the tabs behind the front console
Pull the top panel up and off of your dryer
You should now see the control board
Take a photo of where the wiring connections go, so you can ensure you install the new part correctly
Release the locking tabs from all wire connectors. Pull the wire harness plug from the connection receptacle on the control board.
Remove the screw that secures the control board in place, and remove it from it’s mounting brackets
Before you take the new control board from its package, touch the metal frame of the dryer to dissipate any static electricity that’s present.
Position the new board on the support bracket, and push onto the mounting slots
Lock it into place and line up with the mounting screw hole
Replace the mounting screw
Refer back to your photo and begin connecting all wires to the new control board
Make sure each wire harness plug is snapped into place completely
Place the top panel back on your dryer, and position it slightly away from the tabs located behind the control panel
Push the panel forward to engage the tabs
Work the panel into place and replace all screws
Restore the power to your dryer, and don’t forget to turn the gas back on if you need to
Push Start Button Relay Stuck
Another issue which may cause dryer to keep running is when push start button is stuck.
It always sends the power to the dryer motor right after you close the door, causing dryer works non stop.
In the end, these are the two most common problems that cause a dryer to say on until the door is opened.
