I have a clothes dryer with a 120VAC push to start button. In
measuring the terminals, both sides are hot (120V) with respect to

I thought there was a short on one side of the push button but the
dryer is working properly. Normally it should be hot only on one side.




Not really a simple question...Your description leaves me scratching my
head.

What are you measuring those voltages with?

If it's a meter, what kind, digital or mechanical movement?

Can you locate a schematic diagram of the machine wiring? That should
tell the tale.

Could be there's an electrically latched relay is the setup which closes
a set of contacts that "short" your push to start switch. When the dryer
is stopped by the timer running out or someone opening the door, power
to the starting circuit is cut off and the latching relay drops out.

Capice?
