Can't control fan with M106

I'm scratching my head on this one and would appreciate a steer in the right direction. I have a dual extruder setup with a fan for each extruder (identical 5V fans) and a fan for part cooling.
FAN0: Extruder 1
FAN1: Extruder 2
FAN2: Part Cooling
I can control fans 0 and 2 with the M106 command, but I can't control FAN1. I have confirmed there is nothing wrong with the wiring/fan by unplugging the fan from the Duet headers and connecting to some external 5V header pins.
The fans are configured as follows:
M106 P0 S1 I0 F500
M106 P1 S1 I0 F500
M106 P2 S0 I0 F500
Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.17e (2017-02-10)
WiFi Server Version: 1.03 (ch fork)
Web Interface Version: 1.14a
Any help would be much appreciated!
