Only one fan working
There are two causes of your problems:
1. The fan needs you to manually turn it to start running.
Problem: The motor bearings both ends are dried out.
1. Remove the motor/fan from the motor housing (there are two screws that hold the motor to the housing. The only way I know how to get to the screw is to bend one of the fan blade up and use a long screw driver to get to the screws.
2. Remove the two screws that hold the bearings to the motor.
3. Detach the bottom bearing (opposite of the fan end.) You might have to use a flat screw driver to pry the bearing off.
4. Use a Q-tip and soak it with motor oil or grease then lubri- cate the fan end shaft/bearing.
5. Use a Q-tip + alcohol to clean up the bottom bearing hole, then lubricate it with grease or motor oil.
6. Put the motor and bearings back together and make sure that the fan can turn freely now.
7. Install the motor/fan back into it housing.
The fan should turn on its own without you helping it.
If the fan won't turn, you have a bigger problem. See below.
2. The fan won't turn at all and is really tight even when you try to
turn it by hand.
Problem: The transformer coil(s) is/are burnt out. Chances are you let the fan run dry to a point that it squealed and started to smell like it was burning before it quit all together.
1. Remove the filters and their housing on the bad fan side.
2. Duct tape a piece of plastic over the bad fan opening.
3. Run the humidifier with one fan. It works just as well.
1. Buy a new humidifier.
2. Make sure you lubricate the bearings as soon as the motor begins to squeal.
Solution 3: You need knowledge of electricity
1. Take the motor/fan out from the housing.
2. Use a vote meter to check the resistance in both coil of the transformer; should read about 17 ohms. The coil(s) that has a high reading or if the meter shows 'OL' is bad. Remove the Yellow tape from the coil to see if you have a loose soldering joint between the coil wiring the electrical cord. If yes, solder the joint back together, check the resistance again to make sure you have about 17 ohms. If the answer is yes, put the yellow tape back on the coil and use electrical tape to secure the tape. Hopefully, the fan should work now. Good luck!
