This fan has an oscillating grill with independent sync motor and timer circuit. Yellow has a medium speed label and blue has a low speed label.

How to test a 3 speed fan motor. Do the following with the motor disconnected. Test the first set of wires. With a multimeter set to low ohms usually 200 test between each winding terminal and the metal casing of the motor. Now is the time to test the white brown and white wires. The electric motor is a bm 122 decomin brand 3 speed motor. It has a 3 speed fan motor.
White wire has a high speed label. There are 6 wires. The freezer light should turn off and the evaporator fan should kick on after a few seconds. Identify the type of motor and examine its nameplate information. Reverse the leads on the capacitor. This is the schematic from the manual of the fan which i salvage this motor from.
I have a bionaire brand table electric fan. Small fan motors last a long time due to few moving parts. If there is any reading on any of these then the motor is bad do not use it. Check for mechanical binding or seized. How to check an electric motor if it is bad. Place the leads of the ohm meter on the wires that run from the capacitor to the motor.
Ball bearings in motors can wear out without lubrication. The type of. The motor uses. Switch the volt meter to the ohm setting. Press and hold the switch for a minute. If it turns on you should be able to clearly hear the electric motor activate and then a low hum from the fan spinning.
I have no knowledge about motors. The motor has a 4mu 250volt capacitor. The white wire is called the run wire. If the fan motor does not turn on while you hold the switch the motor is probably bad. There are 4 wires connected to the motor coloured white yellow blue and black respectively. Count to three while the leads on the meter charge the capacitor.
Hope someone can enlighten me on the. Sounds like you have a winding down to ground. Take your multimeter and set it to ohms. Something was wrong with the solid state circuitry everything worked but the motor but a quick test of the motor indicated it does work.
