Check fan cage to make sure it turns freely. Check voltage to IFM make sure it is correct for the application. Make sure the motor turns the fan cage in the correct direction. IFM will have high and low speed make sure when you change from fan on to auto that the motor changes speed. If you have an amp draw meter check to see when running the motor pulls the amp load it is rated for. Recheck all wiring.

1999 Toyota Rav4 blower motor not working


Confirm that you have power reaching the motor windings. If positive, then the anomaly is centered around the motor.

I am eplacing my home a/c blower motor myunit has a white wire my new motor dosent How do i wire it??


Assuming the motor has the same rating as the one your are replacing, almost all motors have a small schematic on the side.
I am not certain you have a good replacement blower motor due to the color of the wires. If the information on the nameplate data matches, then you are probably safe in going ahead and using it.

(Warning: remove all high voltage to unit before working on unit)

Two of the leads will have to be placed on the same connections as your old motor so trace them back to the control board and install the wire on the same locations. Most blower motor now days have capacitors on them. Make sure you have the replacement capacitor that your blower motor requires. It will say on the schematic on the side of your new motor what the size is. Typically somewhere around 3 to 20 MFD. MFD is short for microfarad. Capacitors are rated in microfarads and in order for the new motor to operate efficiently you must get the manufactures recommended capacitor. After you replace the motor and capacitor, on startup you need to measure the amp draw on the new motor to make sure you will not burn up the new motor. The amp draw maximum will be on the motors nameplate data and when operating, the amperage cannot exceed the nameplate data. If it does it will burn up the windings and stop.
If during any of this sound like something your not confortable performing, please call a competent technician to replace your blower motor. If you burn up the motor, the retailer that sold it to you will not replace it if your not a trained professional.
Hope this helps

My 2003 suburban rear blower not working replaced blow it works jumped out check resister I have 12 v going to the resister but ony 1.7 volts to blower replaced resister worked for a week then stoped...


If your original blower burned up, or if the original resistor failed, it is likely that some of the wires leading to the resistor and blower BURNED slightly in the process, and will need to be replaced all the way back to where they connect to the fuse block. (The wires may have been pinched or otherwise damaged somewhere, so they no longer carry the amount of current required, causing the resistor to fail due to a low-voltage over-current condition.) Sadly a failed resistor can also burn the motor out. Check the windings of the motor (via the connector) using an ohmmeter to see if it is still good.

2001 aurora when fan is on high for a period of time it smells like the header is burning.


Not sure what a burning header smells like, but I would expect two possible smells. First, if the blower motor itself is going, you might smell the windings getting hot - like a transformer burning. If this were the case I would expect that the motor wouldn't spin on the low speeds.
The other smell you sometimes get is when the heater core leaks. Then you will get a coolant smell inside the car and sometimes (usually) a wet carpet as well.

I have a bull frog spa with two flo-master pumps, specifically Emerson extreme- e model number r23mwdma-175. Spa is noisy and had made a burning smell. Is this a motor, impelled, or other problem? My...


Common sources for a burning smell in order of most likely, depending on how your spa was equipped, in my opinion would be:

Blower motor - Worn out brushes on a DC motor arc heavily and will give off an odor.
Heater - Elements build up scale over time with less than ideal water chemistry and will give off an odor when heating.
Pump - As a pump nears total failure it can overheat enough to begin to burn the winding insulation and tie down cords causing a burning smell.
Control box/electronics - least likely but a failing relay or GFI recepticle can also burn and eventually fail.

Not blowing air smell like something burned coming from vents


The blower motor may have burned out or the control board you will need a multimeter to test motor leads of the motor. You need to ohm out the motor windings to see if they are open if they do not ohm out then the motor is probably burnt or on a thermal overload in which case you will have to let the motor cool down and see if it will restart after cool down.

Intermittent blower motor failure


A broken/burned motor winding will do exactly this. If you measure it when cold it will look good. The broken/burned winding will only open from heat expansion.

Vacuum plugged in but not on, smoke started coming from the motor


The motor winding burned out. Perhaps the motor was very hot when the vac was turned off after the last use and the insulation of the motor windings broke down when the air stopped moving thought the unit. Perhaps also the polarity of the receptacle it was plugged into is reversed or the plug on the vacuum is not polarized. Those things in combination could cause this but this is kind of a long shot guess. In any case the blower motor is likely burned out and will need to be replaced and checked out.
