Gfci trips heater not turned on

I have a Pentair Minimax 100 and as soon as I plug it into the GFCI outlet, the outlet trips. The heater is not even turned on yet! Tried it into 2 different outlets and the outlets don't trip with anything else plugged in. But as soon as I plug in the heater, automatic trip. Thoughts?

GFI is Ground Fault Interrupter (or GFCI - Ground Fault Circuit Interrupter) It is doing its job, telling you that there is a short in the unit or wiring. Have a certified electrician check the wiring and unit.

Hi lg washer dryer combo trips safety switch as soon as plugged in and wall turned on


The washer tripped the breaker once and OR after the breaker was reset it ran additional loads with no problem then it tripped the breaker again.

Intermittent problems are always difficult to diagnose because the problem usually doesn't occur when you're making the checks.

If the washer ran additional loads the problem will not be an electrical short with one of the washer parts. If the lid switch had a short it wouldn't run additional loads.

if the additional loads used the same cycle as previously. A timer can have an internal short that might trip the breaker in heavy duty cycle but not the permanent press cycle.

If you have access to a clamp on amp meter, see the image below, then you can check the amp draw of the washer. The washer normally will draw about 10-15 amps at start up and about 5-8 amps while running. The house breaker for you washer should be rated at 20 amps.

If the washer is running and drawing less than 20 amps and the breaker trips then if can be a weak house breaker.

Mid cycle the washer is most likely draining or spinning and if the bearing or pump locks up then the washer may draw additional amps to try to start and trip the breaker.

The key to this problem is what the amp draw of the washer is when the house breaker trips.

To narrow this problem down, there are three places that could be causing the ( outlet) GFCI to trip, a malfunction in the washing machine, a problem with the downstream wiring (aka load side of the GFCI-other items connected on same circuit), or the GFCI outlet itself. If there isn't anything downstream, then plugging the washing machine into another GFCI outlet, or simply swapping out the outlet for a known good GFCI outlet, will identify if the outlet itself is faulty.
If the outlet trips when the washing machine isn't running and isn't even plugged in, then there's a fault in the wiring on the load side of the GFCI outlet.
If the issue is neither of the above, then running the washing machine and monitoring to see which step is occurring when the trip happens will isolate what part of the washing machine may be leaking current to a ground. It could be a certain water level, a motor being engaged, a transition step in the controller, etc
Beware some techs believe that most Washing machines or any other motor should not be on a GFCI! Should be a dedicated single receptacle. If there are other outlets on the washer GFCI, replace that GFCI with a single receptacle and put the GFCI on the next jump in order to protect other outlets.

Another item to check is ur lid switch which may have gotten moister inside and created a short_ or broken open and the rubber seal dried out over time, and the switch assembly will be exposed. water can splash onto the assembly, somehow causing the GFCI to trip. In any event, if you are having trouble with your washing machine stopping mid-cycle for any reason, test and replacing the lid switchis probably a worthwhile idea, as it is cheap and easy to replace.
By the way my advice is free cuz God is good!

Coleman mach rv ac unit tripping breaker


If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

2006 Chevrolet Duramax block heater trips on a ground fault circuit but works on an unprotected breaker. Why does it work on one but not the other? Will this damage any truck circuitry?


Hi Funny,

If a GFCI trips or causes a breaker downstream to trip, something needs to be altered. Do not by pass a GFCI. It is designed to save lives and property.

It's drawing a lot of current. The most likely cause is the cord you are using is too light (14ga. or higher) or too long.

Depending on the length, extension cords should be 12ga, minimum, preferably 10 ga. When in doubt, go heavier.

The block is supposed to heat up, not the wire.

Best regards
Mike

Delfield freezer 6151-S keeps tripping GFCI


Try it in a normal plug. Freezers and refridgerators just pull too much to be used on a GFCI. The more a GFCI is used the eaiser it trips.

Keeps tripping circuit breakers bunn NHb


Hello

Coffee makers have a heating unit in them which draw a lot of current. If it is on the same circuit as refrigerator, toaster and other it will trip the breaker. Also, some breakers are more sensitive than others. Have an electrician run a separate circuit for the coffee maker outlet. Try running it in the dining room outlet, which I hope is separate from the kitchen outlets. Is the house old? Older homes have a lot of mixed up wiring.
