Kenmore 11097350100 gas dryer not heating

[Edmanep]

Motor runs, will not ignite on any cycle

Originally Thermal fuse was blown so I replaced it after cleaning out much lint from blower path 

no joy

replaced igniter, flame sensor, both thermostats and even the solenoids 

no joy

tested all new parts for continuity and igniter for resistance - all passed (I’d done the same before installing them - I’ve purchased bum parts before)

no joy

Even replaced timer with “open box” timer off eBay 

no joy

checked all parts again plus all connections

no heat cycle at all. No glow 

think it’s the timer?

it’s very tough for an amateur to find definitive DYI testing for timer.

suggestions?

test the amps on the igniter  whatever the spec is it needs to be at that spec
