Dryer Repair - First timers
We have never repaired our dryer. We did some troubleshooting (youtube and this website) and decided to try two parts. This was one of them (the other was the door switch). It was a little difficult to get to because the screw heads faced the side. So, front off, drum out, side out, but then installed in seconds. Dryer back to work!

Dishwasher would not start
Removed panel to access the interlock switches. There were two. The button on one switch was fine and the button on the other would not depress. Ran a continuity test and it failed. The switch also had a burnt smell

My dishwasher would not start.
I unscrewed the inside of the dishwasher door and clearly saw the old interlock switch. This dishwasher has two, but it was obvious that one switch worked and one didn't (one switched was permanently pressed in). I removed the old interlock switch. It was tricky to pull out and I felt like I was going to break it but after watching youtub

There are 2 switches that should be pressed in when you move the handle to lock door, the switches usually go bad with time.

First, no heat; then, no run
Washer/dryer belongs to a friend. Originally, the problem was that the dryer wouldn’t heat, so I opened it up, and removed the drum thinking it might be the heating element. It wasn’t, and the ohm reading confirmed this. It turned out to be a burnt wire connector to the element ( unknown to me, and found out later, was that the start swi
... Read moretch had remained continuously in the down position because the switch was pressed too far down and thus remained locked “on” in place under the surrounding cabinet frame. This, in my opinion, caused for a continual call for heat and thus burnt the wire.)
I replaced the burnt wire/connector and reassembled. Now the dryer would heat, but would only run if the start button was continually depressed. Let go of the button, and the dryer stopped.
Repair pros suggested a new start switch. I bought a new start switch along with a new interlock switch (it basically shuts off dryer if belt breaks because lack of a belt releases pressure on the pulley that keeps switch depressed.) Apparently they can go bad, too.
It turns out neither of these switches were bad. Instead, upon further inspection, after the first installation of the drum belt, the L-shaped bracket which holds the pulley for belt tension became dislocated from its correct position and was not allowing for the depression of the interlock switch, causing the dryer to “read” broken belt, and thus, not run.
I loosened the motor bracket to allow placing the bracket in the correct position. Reassembled and all was good. PSA - almost every sheet metal edge is razor sharp. In the process of returning parts. Now in the process of returning parts.
Took the screws out of the back of the doorl located the switch and replaced it put screws back in and it was fixed

Dryer will only run if the start switch is depressed. I have replaced the start button. Could problem be in the idler switch or what is your recommendation?
For model number GTDP180ED0WW
Hello Tyson,
Thanks for your question. It is likely that there is a problem with your interlock spring switch, or that the drum belt has become loose. The motor will not remain running when the start button is released if there are loose wires with the interlock switch. You can also test the switch for continuity if you have a multi-meter, and we would advise to replace it if it is not showing continuity.
I hope this helps.
Dishwasher was working one second and not the next after my wife stopped it for a second or two. I see there is 2 interlock switches with buttons. One button is up and the other is stuck down. Is this normal or should they both be up and able to spring up and down?

Hi Brian, Thank you for the question. Both parts should be up when not engaged. Hope this helps!

Where is the interlock switch on the dryer? Only seeing for the dishwasher
For model number DCVH515EF0WW
Hi Zach,
Thank you for your question. Your interlock switch is down by your motor inside of your appliance. When you look at your model diagrams on our site, it is underneath the blower and motor diagram. I hope that helps. Good luck with your repair.

My dryer will not start. When I press the start button, it clicks. I've replaced the door switch. And thermistor. Any other suggestions? Thanks. Steve
For model number DPSE810GG6WT
Hi Steve,
Thank you for the question. I suggest replacing the Interlock Switch,PartSelect Number PS1481922 (different from the door switch). The interlock switch may also be referred to as a belt switch. This part is a simple on/off mechanism that prohibits the appliance from operating when the door is open.The interlock switch senses the door is shut and the dryer can begin. This part might need to be replaced if your dryer is not starting.
Hope this helps!

Dryer will only run while continuously holding the start button...drum rolls, motor runs and it heats up. repairman looked at it, turned the start button and said it needed a new motor, sorry. no other testing was done. if the dryer works holding the Star button, couldn't it be the interlock switch?
For model number DBXR463GBOCC
Hi Mary,
Thank you for your question. This issue is usually caused by a either an interlock switch or a motor relay. If you are handy with a multimeter, you can test the parts to see which one is causing the issue. I hope this helps. Thank you and have a great day!

Our dryer intermittently starts, my wife has to slam the door a few times and then it will start. I've changed the door switch so now i'm trying the interlock switch. Where is the interlock switch located on my dryer?
For model number DHDVH52GF0WW
Hi Dale,
Thank you for your inquiry. There are some parts that you will need to check to see which one is causing the issue. You will need to check the interlock switch, the drive belt, the door switch, the door latch, the idler pulley wheel, the door strike, the slides, inlet control thermostat, the igniter, and the rear drum bearing. I hope this helps. Thank you and have a great day!

Hi, I am not able to turn the power on for my GE dryer. My husband did remove the plastic exterior push button and I can start the dryer by pushing interior black dome shaped button on with a screwdriver, however I would like to get a replacement part to actually fix the machine. I am just not sure exactly which part is required? I have had the dryer for between 5-7 years. I love GE products and have always used them, however I am a little bit disappointed this time with the washer and dryer I have as both of them are not that old and have required repair already and now again. The first two times on the washer required a service call with repairmen. Thanks for your help and quick response. Sincerely, Janet a. Gross, loyal GE customer
For model number GFDN240EL0WW
Hi Janet,
Thank you for contacting Part Select. The start button you need to replace is only sold as part of the Control Panel Assembly - White. Part number PS3487098. The start button is part of the panel and should not be removed so it is not sold as a separate part.
Hope this helps!
Dryer will not start when I push the start button, but it makes a humming sound. What should I check and how do I test it?
For model number EED5600G6WW
Hello George,
Thanks for your question. The humming and lack of starting may indicate that the door switch, part number PS2344321, is at fault. I would recommend testing the door switch for continuity with a multi-meter, and if it does not test for continuity, replace it.
I hope this helps.
GE profile dryer. Press start button, hear a click, "drying" light comes on. Drum doesn't spin and no sounds coming from the motor. Actuating door switch makes a clicking sound on the control board (as if it's trying to stop the motor, but the motor is not running). Continuity check on door switch, high limit thermostat, and belt switch all seem ok. Motor and drum spin freely (by hand) and belt is in good shape. Any ideas what to check next?
For model number DPSE810EG0WT
Hi Steve,
Thank you for your question. I could probably suggest just taking a quick look at all of your thermostats and your thermal fuses. You should have at least two of each on your appliance from what I am seeing. two on the blower housing and then two on the heating element. If all of your parts there are fine, you may have to look into your motor being the issue. I hope that helps. Good luck with your repair.

We started our dishwasher, and for unknown reasons it stopped running when the cycle knob was approaching the "rinse only" cycle. We attempted to restart by opening the lock, then closing it back, then turning the knob back to start, but nothing happens! Can you help?
For model number GSD2000J01BB
Hello John,
Thanks for your question. There are a few different parts you will want to test with a multimeter to see if they have continuity. Replace them if they show no continuity. Test the interlock switch and the door latch. You may then want to test the motor and pump out to see if they are working properly.
I hope this helps.
