    MiniMax NT 400 blower fan motor does not come on

    I have one of the older Minimax NT 400 (I know its horrible) heaters. The fan was not coming on so I pulled it off and noticed the squirrel cage was rusted. I replaced the entire unit. Even after replacing the motor the fan does not kick on. The fan does feel warm to the touch. I called pentair and they had me jumper the ignition module but this did not work either.

    Any thoughts on what else it might be?

    Yous should get an error message on the display. Do you? You also replaced the entire blower correct not just the squirrel cage?

    Yes I replaced the entire motor. I am not getting an error codes now. Prior to replacing the motor I received an E04. Now I hear the motor hum like it has power but nothing. No blower, ignite, etc.

    Did the motor spin ok when you put it in? If so, usually when it hums like that it's either a frozen up motor or a bad start/run capacitor. Seeing yours is a new motor I would have to check to see that the motor is getting the correct power to it.

    Yes, it was spinning. The capacitor was new and came with the motor.

    I just pulled the motor off and noticed that the flap that appears to be to prevent debree does hit the cage and when it is in the down position could block it from spinning. Is OK to bend this piece out of the way?IMG_0377.jpg

    Yes I would bend it a bit to allow the fan to spin. It should not be making any contact with the fan.

    I have replaced the blower motor with a new one since it would not spin.

    The power, pressure switch lights are on. When I activate the heat there is a click and the temperature light comes on green. Then nothing.

    I jumped the f1 and f2 on the ignition module and the fan comes on and spins. Does this mean the ignition module is bad?
