I'll test whether I'm getting 120 at the motor, but as the motor is brand new (I replaced it monday), I'm not very worried about it being good.

When you installed it, did you remove a blue wire from the harness that goes back to the overload protector? and then attach the blue wire from the dryer harness directly to the overload?

That contact need to be closed for the motor to run, 123v means that it is open - can you jumper it and check for voltage at blue and white motor wires again

I'm not sure I understand the Q--I treated the blue wire as hot and the white as neutral. Should I swap?

No - measure the blue going in to the motor to ground, if you have full voltage there, you may have a bad neutral somewhere (bad connection, broken wire etc)

BTW - you still have T-W jumped, yes?

Somehow you are losing power between the W contact on the timer and the blue feeding the motor, measure from the blue at the motor to the W contact - check wire for breaks etc

T-W to the blue motor lead gave me 1.3 V! I also tried BU instead of T-W, and I got 123V. From the earlier test across T-W, where I was getting 123V, and you said that showed it's open and should be closed, doesn't this point to a problem in the timer?

From the BU terminal, power then goes through the push to start switch (r1 - r2), once the button is depressed, the relay coil should hold it closed - keeping one meter probe on the BU terminal, touch the other probe to each side of the switch, then to T, then to W etc - the point where you see line voltage (120v) is where the circuit is open
