When push to start button is depressed the dryer will run but when the button is released it will stop. I've read that it could be the motor relay, control board and the motor, how can I figure which it is without buying all these. Any assistance would be appreciated.

Thank you,

I've read that it could be the motor relay, control board and the motor, how can I figure which it is without buying all these.

It will not be the motor as this motor does not have a centrifugal switch for the start switch bypass.

Could be the relay or the control board.

I believe that the heater and the motor relays are the same.
Double check this just to be sure.
If they are unplug the unit and swap the relays.
If it now runs but you have no heat then it is the relay.

Thank you, I switched the relays and still didn't work. I tested blue wires on both relays, only one was getting 120v and the other wasn't on both of them. Is it possible both relays are bad?

Appreciate you fast response and assistance.

[denman]

Is it possible both relays are bad?
Very unlikely.

Sorry but I do not see a blue wire going to both relays.
Also you did not say under what conditions you did the test re: was the start switch being held on etc.?

[2rbarajas]

On the first relay next to the push to start switch it has 2 blue wires and 2 red, the top blue wire will read 120v with button not depressed and depressed. The bottom blue wire will show no volts with the button not depressed but shows 120v with the button depressed. The other relay next to the control board has 4 red wires and I get the same results as the one next to the push to start relay.

Thank you for taking time to help me.

Your test of the motor relay does not really tell you much.

You see 120 on the top blue wire because that is connected to L1 through a set of contacts in the timer.

You then see it when the button is pushed because the start switch is closed and is in parallel with the motor relay contacts.
This voltage also goes through the BU/BK wire to START SENSE on the board. This tells the board that the push to start has beenppressed and it then sends voltage to the relay's coil to hold the relay contacts closed once the start switch is released.
I hope that I did a decent job explaining the above.

I do not have a spec on the relay coil voltage so check on the relay. They usually show it.
Then measure from P3-2 to P2-7 on the board or on the wires at the relay. If you do not see any voltage then the board is probably toast.

[2rbarajas]

You lost me on this one, P3-2 P2-7, I could not find anything like that on the board. I'm to replace the board by just going on a hunch and by what you have commented on the motor and relay.

Thank you for all your advice and help.

[denman]

I just follower the wiring on the relay coil back to the control board.

Th P is usually the plug number and then the second digit is the pin in that plug.

I would also replace the control board as it is the most likely cause.

If ordered from AppliancePartsPros they will allow you to return it if it does not fix the problem, see their return policy.

Denman, just wanted to let you know that with your help and advice I was able to take care of my problem, it was the control board as you had thought. I really appreciate all your help and assistance you provided and nice to know that people like you are willing to help those that who are less knowledgeable.

Thank you,

[denman]

You are welcome.

And thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.
