If the furnace is more than ten years old and it has an oilable motor, it could only need a few drops of light weight oil. Usually, the bronze bushings utilized in blower motors wear a bit over time and cause excessive 'end play' in the motor armature which causes excess 'drag' causing them to have a problem initiating rotation.

Other times, a bad run capacitor COULD be the problem. On a fractional horsepower blower it could be as low as 3 mfd, 5 mfd or possibly as high as 7.5 mfd. Slim chance because it for a bad capacitor to cause your condition it has to have lost some of its capacitance and this happens only RARELY. T

Try looking for little yellow plastic or grey pot metal plug on the motor end where the wires come out. If you are lucky there will be two plugs, one for each end of the motor. The one typically that goes bad is the mostly inaccessible inner bearing that holds the weight of the squirrel cage blower wheel. Hopefully that bearing has an extension tube connected to it and is accessed next to the outer bearing oil port.

Also a great percentage of motors are lubricated for life and have no oil ports in which case the motor needs to be replaced.

SOURCE: furnace blower not working how it should

first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

Can blower motor, cig. lighter, fan cooling motor, door locks all be tied into the blower motor relay faulting out?

Sounds more like a key switch or fuse box problem.
The circuits you mentioned would be on separate fuses but could be connected to the key switch. The relays are grounded by the engine computer to be energized.

Heater blower not working

You call it the blower motor, I assume you mean the interior Heater/AC blower motor. When the motor acts as you have described it is usually a problem in the motor itself like a short or rectifier.

If this is the Manual A/C type, there are two common occurances affecting blower operation.
1st, there is intermittent contact in the blower motor brushes. You can check this by locating the blower motor housing under the dash on the Right Hand side (Passenger Side). With the Ignition Key in the "ON" position, blower switch on "HIGH" firmly slap the housing with your hand. If the motor starts working, there's your problem. If it doesn't, rig up a 12 volt test light bulb and back-probe the connector to the blower motor - Does the light bulb turn ON? If so, then the problem is with the blower motor itself. If it DOESN'T turn on, then the problem is elsewhere (blower relay, blower control switch, or wiring to the motor or from the motor to ground.
Go to and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, campaigns, illustrations and procedures, etc.

Excessive black smokw on start up when cold (2)low oil presure when hot

Slight engine wear. Would advise using a heavier oil. The 5w 30 is great with low mileage. As an engine wears & the miles add up the internal parts get looser & a heavier oil should be used to help. Would start using 40 weight oil. Some smoking will continue but you should see a decrease in the morning start up & a rise in pressure during the day. There's also the STP & other motor oil honey/additives that can help these symptoms.

it could be the extra weight on the motor and the motor is bad,try this,open the door,push the door switch in with one hand and spin the drum with the other hand and have someone push the start button,if it runs and most of the time it does because you're helping it along you need a new more thing,if the filter is in front,remove the duct that the lint filter slides into and spin the drum,if the blower wheel moves with the drum you have a bad motor,if it doesn't you have something stuck in the blower wheel and it jams up the motor because it's attached to the motor shaft.

The relay for the manual blower system is a different relay from the others. It has terminal 87 which is the high amp terminal. It comes through fuse 3 on the relay center, a 30 amp fuse. It it is right hand underhood.

The relay also contacts terminal 87A which is the lower power circuit that gets 25 amp from fuse 5D in the instrument panel fuse block. That supplies the 3 lower speeds and when switched to high applies voltage to the relay switching it from the 25 amp circuit to the 30 amp circuit.

The SAME wiring supplies the blower from the relay on to the blower. The blower uses only one ground which is terminal B on the blower motor. Your motor should have run the same but when you disconnected the terminal socket for both A and B from the blower motor, there was no ground. You do have to supply your own ground!

Easy check is fuse 3 in the relay center. Hope it's blown. Might question why it blew, but that's an easy replacement. I might indicate impending blower motor failure with age and high current loads.

it could indicate the relay is stuck on the 87A contact and not switching under power to the other terminal. Could be primary circuit blown not pulling the relay or could be the contacts are physically burned to the most-used contact.

The dryer is plugged in and the circuts seem to work however the dryer is making a humming noise but it will not turn on fully.

what do you mean it won't fully turn on?do you mean the motor won't run because usually when it humms you either have a bad motor or something is jammed and stopped the motor from spinning.try this,open the door,with one hand hold the door switch in and with the other hand spin the drum,have someone else push the start button while you do this,if it starts the motor is bad,if you can't spin the drum something could be stuck in the blower wheel or the belt broke and could of jammed up the motor but it sounds like you have a bad motor.let me know what you find and next time send the brand name and model number.

Air conditioner blower doesnt come on

Have the blower motor checked to see if there is voltage to the motor,if there is not the blower module is most likely the problem,it is right next to the blower motor ,wires from the blower motor will go right to it,if there is voltage to the blower motor,then the blower motor is bad,sometimes,not always,if you bump the blower motor with your hand while it is on,and it starts trying to work,this will tell you that the blower motor is most certainly bad.
