Yesterday I cleaned my HM1450 humidifier. Today it turns on (i.e. indicators light up) but the motor won't start. Is there anything I can do to fix it?

Hello,
A console humidifier that fails to humidify a room could have a bad humidistat, fan switch or float switch--problems that take specialized equipment to diagnose. But before you call in a pro, it's worth your time to test the fan motor and float assembly, since repairing them is something you can handle on your own.
Testing and fixing the fan
Steps:
1. Test the fan motor. While the machine is plugged in and full of water, turn both the humidistat knob and fan-control knob to high. If the fan hums but does not turn, or turns slowly, the motor needs to be replaced. If the fan won't move, you may have a bad switch somewhere. Call a professional.
2. To replace a bad fan motor, unplug the machine and disconnect the fan wires from the switch panel. You may have to pry apart a plug, use needle-nose pliers to pull the connectors off the switch, or unscrew the connectors.
3. Remove the old motor from its housing, using a Phillips screwdriver or a nut driver and socket.
4. Remove the fan blade from the motor. Use adjustable pliers to open the spring clamp at the center of the fan blade, and then slip the clamp off. Use a flathead screwdriver to gently pry off the blade, then set it aside.
5. Take the motor to an appliance store to buy a replacement.
6. Install the fan blade on the new motor, then install the motor and reattach the wires.
Testing and fixing the float assembly
Steps:
1. Locate the empty tank float assembly. This assembly consists of a switch, a connecting rod (on some units) and some type of float. It's supposed to shut down the machine when the water reservoir is low, but if the float jams in the down position, the dehumidifier won't turn on.
2. Check the float and connecting rod, if there is one. If the parts are bent and touching the cabinet, use gentle hand pressure to straighten them so they move freely. If your dehumidifier has a float switch that is triggered by the filter housing moving up and down, make sure the housing is centered in its tracks and moves freely. Clean any debris and dirt out of the channels, using a scrub brush.
3. Check that the float connecting rod is contacting the float switch. If it isn't, bend the end of the rod so it touches the switch.
kindly check also if the fuse are not burnt.
wish you good luck,
take care.
