Lawn mower batter charger blows circuit breaker

I'd try plugging it into another outlet first, then try turning off any other appliances that might be on that same circuit. If it continues to trip the breaker, I'd take it to the small engine shop.
hope this helps

I have an earthwise 12 amp electric lawnmower that trip the circuit breaker and now will not start at all. Any suggestions on what might be wrong and how I could fix it

If the circuit breaker trips there are three possible reasons
1. the motor is being overloaded - clean underneath ( as recommended above); or if the grass is too wet or too long or both you may need to handcut; or the motor bearings need lubricating (same problem as me-how?)
2. There is an electrical fault - check the plug and cord (as above) or get an electrician to check the motor and connections; or the carbon brushes to the motor need replacing
3. You have a faulty circuit breaker! - borrow and test with a replacement

My lawn mower just stopped working. I was mowing along and it just stopped. It is an electric Black and decker. I was mowing regular grass, nothing complex. It was working fine before that. It is very new...

Open your circuit breaker box. Locate the breaker that has tripped. Turn the breaker OFF (it is in a mid position). Then turn it back ON. Before you do that you need to ask yourself, why did the circuit breaker trip? They trip because of an overload of current. Is something else running on that same circuit, say for example an electric heater or something similar? Depending on the rating of that circuit breaker (15 or 20 amps) you may be drawing too much current. Look for anything else that could be running on the same circuit (only so many outlets can be put on the same circuit). Disconnect or turn off all other devices. Attempt to operate your mower again. If the breaker trips again, then there is something wrong with your mower (electrical short?).

Electric lawnmower trips circuit breaker as it gets up to speed

Hi Dogtown,

Cool name. Been there. Went to a heavier gauge extention cord and made sure nothing else heavy was on the same circuit.

Problem disappeared.

Best regards

Replaced switch but circuit breaker trips on start up ! Mowermm600

Your circuit breaker will trip because of two main reasons:
  • Electrical power point circuit is overloaded (too many appliances active on the same power point circuit)
  • Power Lawn mower has become unsafe as your active live is able to reach your earth connection (e.g. short-circuit). Make sure that you have correctly reconnect ALL your power leads wires (check that the Active and Neutral wires have not been transpose). With power off/device unplug, use a multimeter on resistance range and verify that your active lead pin is not showing a reading against the Earth (middle) pin when the mower switch is turn on or off! There should not be any resistance reading between the Earth and Neutral (opposite pin to Active) pins either!
Hope it helps.

Electric lawn mower repeatedly trips house circuit breaker

The breaker is tripping because there is a short in the mower electrical circuit -- most likely in the motor winding -- it overheated.

If you have a multimeter measure the resistance (ohms) of the motor winding by putting the meter probes on the two flat prongs of the power cord with the mower switch on. If you get near zero ohms, the winding is shorted -- motor "burned up".

Using the multimeter again, check for continuity between the round ground pin on the power cord and each of the two flat prongs. If you get continuity on either of these, there is a short to the mower chassis. This can probably be corrected without much expense.

My bet is on the motor winding being shorted.
