That is your inducer blower assembly sitting on top of your heat exchanger cover. We basically have the same heater as I have a Hayward H400idl2bh. Is your heater wired for 120Vac or 240Vac supply? The three wires coming from the motor ( red, white,black ) and terminating in a 3 wire plug should go to a three wire plug at the wall between your control chamber and the inducer assembly . You can remove the male plug from the female plug ( it may have clips holding it in place that you would need to squeeze to take it apart) by gently wiggling it. I can't see from your photo if the motor has a capacitor ( silver oval cannister) attached to it? The wiring diagram on the motor should be labeled 120Vac. The leads on the wiring diagram should show white=(common), red=(low) and black=(high) and two other leads to the capacitor if you have one. If you try to start the heater with the motor leads unplugged, you should read 120Vac on the plug that goes towards circuit board between the white wire and the black wire, as mine starts on high speed. If you measure ohms for the motor windings at the plug hat goes towards the motor, you should get ~ 14 ohms between the black lead and the white lead. Let me know if you show voltage to the motor on start up and what the motor windings ohm out at. Your heater may be a different series/version than mine as the controls/circuit boards are different. I see that your connection plug from the motor seems to make a male/female plug connection at the wall between the controls and the inducer assembly. When disconnecting this connection measure voltage at start up at the part of the plug that goes towards the controls and ohms at the connection that goes towards the motor. It might help me to see a close up of the motor nameplate and the other side of the inducer assembly.
