Duet 2 wifi fan0 is always on now

I'm having an issue where my part cooling fan, which is on "Fan0" per some of the recommendation I've seen, now doesn't behave as expected. I've read that the fan mosfet can fail and cause issues, but can it fail "on"?
The extruder heatsink fan is set on one of the "always on" IOs (I don't think I need to define it, if I'm using an always-on right?)
Old config lines were:
M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
New config lines
M950 F1 C"FAN1" Q500 ; create part cooling fan on pin "fan1" and set its frequency M106 P1 S0 C"Part_Cooling" H-1 ; Thermostatic control is turned off M950 F2 C"FAN2" Q500 ; create case cooling on pin "fan2" and set its frequency M106 P2 C"Case_Fan" S0.35 T40:65 H100:101:102 ; Thermostatic control turns fan 35% on when temp of mcu or stepper drivers is 40, ramps to 100% when temp rise to 65
It works fine now, but what kind of failure can cause the fan0 pin to be permanently on?
If I shift the current config to fan0 and fan1, the fan connected to fan0 stay permanently on.
Post your entire config.g please. It sounds like you might have the wrong fans assigned to the tool.
