Dead - as in No LEDs Whirlpool Duet Electric Dryer

[Artifex]

Problem: Dryer acts as if there is no power at all - no LEDs light up on the control panel so I cannot run any diagnostics.

Actions Taken: Here is what I have done so far:

• I tested the thermal fuse on the lint duct for connectivity, and it was good
• Tested power coming in, and I have a solid 240 volts off the power cord
• Pulled off the control panel and re-seated the ribbon cables on both ends and made sure they were tight - they were/are good.
• As an old hand with electronics I gave the circuit boards 'the smell test' - nothing smells fried, visually no shorted capacitors.

Still completely dead.  I am not sure what else would cause the 'completely dead' symptoms - reading other posts here it seems like all the other failures (thermister, thermal cut off, etc. ) would just throw an error code, right? So the popular next step is to start replacing really expensive parts until it lights up again: control panel ($170) or interface panel ($230).  It's one thing to pop $20 - $30 for a fuse or a coupler to see if that is it, but I am not prepared to gamble like that with upwards of $400 in parts on an older appliance.

Any suggestions?

Thanks!

Make sure you have 120 volts from each hot leg to neutral at back of dryer.
