Started happening Intermitantly on days when we ran back to back cycles..
Now anytime I use a heat cycle within 5 mins the whole thing shuts off (no cycle end tone).
however I can turn it right back on and start the process all over again with out waiting even 10 seconds.
If the cycle is set to air fluff, it runs the whole cycle no issue. Only heat cycles trigger the system to shut.

Iím willing to replace parts just need to troubleshoot the likely culprit without dumping a ton of money
