My duet dryer has been acting up lately. It has been doing the following things:
-Sometimes I push the start button, nothing happens for a few seconds, and suddenly it will start and finish the load with no problem.
-Sometimes, it will only run for a few minutes and stop with partially dried clothes.
-Sometimes I push the start button and the F70 code appears on the display. I turn off the power, and restart the dryer with no problem.
-Sometimes I push the start button and the F70 code appears on the display. I turn off the power, and still get F70 code. Dryer will not run.
-Sometimes the dryer powers itself up as if somebody hit the power button(just the display turns on, not the machine).

From what I researched, the problem could either be (1) Interface Control Board Kit (part number W10294629). Or (2) Electronic Control Board (part number 3407228). Or (3) Electronic Control Board (part number W10110642. Can anyone help tell which part(s) I should buy to fix this problem?

Thank you
