Here is a link to a service manual, your unit is included

Since you replaced the timer we will assume the new one is OK

The wire I would suspect is the white which goes back to Neutral (see the wiring diagram)

I would trace it back and make sure it has not come loose at neutral also check for corrosion on the connectors and any obvious signs of overheating or wear.

If It looks OK but still does not run after disconnecting/reconnecting you will need a meter to check it for continuity

Make sure to disconnect power from the unit while doing this
