Question about Black & Decker 19" Electric Lawnhog Mulching Mower with Rear Bag

1 Answer

Motor has low torque

On/off switch fried. I replaced the switch, now motor will start slowly and wind up to a high speed, but will instantly bog down and stop if I push the mower into any grass. I press down on the handle and lift the blade, and the motor will again slowly build up speed. Replaced brushes and dressed commutator, replaced bridge rectifier. Rotor spins easily with no apparent drag or roughness in the bearings. Problem persists.

Common complains for electric & cordless mower is that they are not ment for cutting on wet or dump grasses or long tall grasses they will bog down. for this type of unit blade should be extremely sharp. also clean the under the deck so you can better air flow for the blade. if your switch & rectifier are new & in right connection then have you armature check for short circuit..

Runs fine on low speed hums on high speed (turns slowly) is it a capacitor problem, internal windings or controller?


Motor itself is the culprit.

Capacitor helps the motor to start spinning from a dead stop, so NO, it is not a capacitor problem.

Probably high speed windings. Means - New Motor needed.

Another possibility, is the controller could be sending power to "Both" sides of the windings: High speed & Low speed at the same time. But normally when this happens, you hear a loud buzz type of sound, motor will spin slowly - if at all.

Good Luck

What part do I need & how do I fix?


I have a 95 grand marquis and i had the same problem. I fixed mine myself by replacing the wiper motor. The problem was the motor will still work on high but not low. Its an enternal issue on the motor that wont allow it to fully rotate when shut off and its not accepting the low voltage to run on low. My answer is 100% accurate

Four winds. My pool pump will not start on the low side when I push the button. It will work on the high side. Also it will pump on the low side automatically after I have run it on the high side. ...


The motor starting switch is probably failing on the low speed side so as long as motor is running on high after starting on high it will continue to run if switched to low. You can try to replace the switch or take the motor to a local electric motor repair shop for them to quote the fix.

Maytag top load will not agitate and only spins on delicate cycle


could have a bad motor,there are two sets of windings in the motor or low and high speed.the delicate works on the low speed and everything else works on the high speed winding,you can check with a meter to make sure 120 volts is going to the motor.sometimes the motor will just hum and nothing else.you'll have to look at the wiring diagram to see what color wires are going to the high speed winding,if 120 volts is coming down but nothing happens you have a bad motor.

I have miele gas dryer t9820 is not rotating inside although it make a sound...


The problem is likely with the centrifugal switch on the dryer motor. This switch connects the start winding of the motor which provides additional torque at startup. Once the dryer is up to speed, the switch disconnects the start winding. If it malfunctions, the dryer will not turn and the motor will hum. By spinning the drum, you are providing enough torque for the start winding to be able to take over and bring the dryer up to speed.

You may be able to correct this by simply lubricating the centrifugal switch which may be sticking. I am not sure if the centrifugal switch is replacable, or if a new motor is necessary if lubricating does not solve your problem

You may be able to solve this if you can lubricate the centrifugal switch with a spray lubricant. If not, you may have to replace the motor. I do not know if the centrifugal switch assembly can be replaced.

High speed does not work but low speed does. Is there an easy fix, or will this require a motor replacement to get both speeds working again? The cooler is a Mastercool model MC64C


If your motor only works on low speed and not on high speed first check to see if you have the proper voltage to high speed. Check with a voltmeter or multimeter, check from common on the motor to high speed on the motor at the switch. If you have the proper voltage then you have an open winding on high speed and the motor needs replaced. If you don’t have the proper voltage or any volts, then the switch is bad and needs replaced. This also will be the same if, medium speed won’t work and low speed does.

Hunter fan with remote control was 3 speed, now only 2 speed


It sounds like fan motor is okay. There are two motor windings -- one low speed, one medium speed. Low winding gives you low speed, medium winding gives you medium speed, both windings give you high speed -- so I would say if you get high speed, both windings are good.

The remote (the hand held transmitter) controls the speed by raising and lowering the frequency of the current which is 60 cycle coming to the fan ceiling box. If the fan speed -selector switch (usually a pull switch) is set to high, when the remote (transmitter) signals the receiver to change speeds, the frequency of the current is changed by the receiver (the receiver is usually in the fan housing).

Sounds like you'll need to replace the remote system -- these come in sets, both transmitter and receiver, and cost about $30. If you're not experienced with wiring fans, you should get an electrician to do the job.

1993 f 150, the blower motor for the heat does not have high, only low and med


These motors use three separate sets of blower motor windings which Low, Medium, and High. The chances are that the selector switch is ok and the High winding or set on the blower motor is not good.

I do not know the color coding of the motor to be able to put 12 volts on one of the windings of the motor to try and force the high to make sure it is actually getting to the motor.

The only way to be certain is to get to the Speed Selector switch and try and find out if 12 volts is being selected to the high side of the switch that goes to the motor. You will have to take the dash apart, which is easier prob. better than replacing the motor which is in the firewall. You might be able to replace it from the engine compartment at a autowrecker, but the high may be a problem Chevy had.
So if you figure out the color of the wire that is the 12 V high, then with the car on and in the high position, apply 12 directly at the motor by exposing part of the wire with a razor blade or a poke through with a sharp tool just to see if it comes on.
Temp solution - Assume the motor is good and the switch may be bad, Remove the medium speed wire and swap it with the High wire and see if it runs on high. Then you will have Low and High ONLY.

There is allot there good luck!
