Rockworth 1700w Breaker - Stoppped working

This breaker is only a few months old and stopped working recently. Power is getting to the motor but it doesn't hammer - There are electrical flashes from the motor housing when attempting to use the device but nothing else, no vibration whatsoever. Is this a problem with the motor brushes (hence the arcing) or something more serious i.e. the main piston. I spoke to NuTool and they think the brushes are ok. Unfortunately they don''t have a technical data sheet available for a few weeks, so I don't want to risk just taking the thing apart just yet. Any help appreciated.

Generator runs just putting out any power

If its running but not generating power it could be a few different things, could be a bad controller board, bad/blown parts in the generator head, or simply a bad connection somewhere. Did it sit a long time before use or was it working fine recently, by recently i mean a month or two max, and suddenly stop working? If its been sitting a long time and now doesn't work its most likely the field needs to be flashed on the generator, if it just suddenly stopped working and was recently then some component died and your going to have to go through it piece by piece to find the fault.

Electrical problem with FA561XF

Could be the breaker. Sometimes breakers just get old and will not hold when a power surge goes through it as when an electric motor first starts up. You have already replaced the compressor with a new one so I would check out the breaker situation. STAY with the same size breaker

Electrical on but dryer does not start

Sounds silly, but because it's an electric dryer, it's run on a 220 line. Double check your breaker box to make sure both breakers are in the correct position. If only one breaker is in the correct position, you'll have electrical power, but the drum won't spin.

Power trips out when jets are switched on

I'm going on somewhat limited information here not knowing if the tub is newly installed or if this is a spa that has been working in the past and just started doing this. It would be helpful to know if this is a recently installed pump as well. That said here are a few things to check.
If it's a new install: Your electrician has more than likely wired the spa incorrectly. Be sure that the spa pack has 220V going into the pack and that the GFCI is wired correctly.
If it's an old spa with a new problem: A lot of times a bad heater element can cause a spa to trip the breaker. If you have a bad element the spa will operate normally for about a minute when you turn the power on, then trip the breaker as soon as the heater kicks in.
If it only trips the breaker when the pump is turned on to high speed, more than likely there is a problem with the wiring of the pump or the relay on the pump itself.

What is this on? If it is a breaker, the grease is to coat the feed wires to keep the corrosion and resistance down

My Kennmore 79363 Gas Range/ Electric Oven electrical doesn't work. Started smelling electrical burning smell, tracked to oven. shut off breaker, smell stoped. Few hours later checked again after...

The person who installed the oven didn't do the connections up tight enough.
I would replace the breaker/power switch with a new one and trim back the wires if the burning is in the breaker. If on the rear of the oven, same applies with badly tightened connections.
If in doubt, call a qualified electrician. That will be better than having a fire!

Is it tripping the breaker on your home's electrical panel? If this is the case, you need to know what that breaker is also feeding, how much amperage it can handle, and what the load demand is. Your washer needs 1700W which is around 15 Amps. If you're on a 15 Amp breaker that is already supplying power to something else, such as incandescent light bulbs, then you're going to trip the breaker each and every time. You'll want to plug it into a 20 Amp circuit that's being used by little to no other electrical devices. A quick alternative is to unplug or power off all other devices before using the washer... or plug it into the same outlet that you use your blow dryer.
