If you do not read 120volts at the push to start relay on either â€œBLUEâ€ to WHITE (timer) (be sure the timer is set & the door is closed) then you do not have voltage from the BLUE wire coming from timer. Either the timer is faulty, miswired or the blue or white wire is bad. The wiring diagram below shows the path of L1 voltage going to BLACK at the timer. Place your meter on voltage place 1 meter lead on BLACK at the timer the other on TAN at the timer, you have to read 120volts there or you have bad supply voltage. If you read 120volts go to BLUE on the timer to TAN, (timer set) you should still have 120volts if not the timer or wire is bad. If you do read 120volts that takes 120volts directly to the BLUE wire on the push to start relay & WHITE on the timer. T to W timer contacts close when the timer is set to timed regular. If you do not read 120volts across BLUE on the push to start relay to WHITE but do to TAN then the timer is bad. You can now jump TAN to WHITE (carefully) at the timer & if the dryer starts the timer is faulty, if not you still have a wiring issue.
SAFETY NOTICE: Be sure to disconnect power to the appliance before performing any repairs. If you are not comfortable with doing any voltage checks that might be recommended, please contact your local service provider for repairs. Be aware that there could be sharp edges inside the appliance that could cause cuts or other injuries to yourself or others.
