Have a Harbor Breeze "Slinger" 72 in fan, microprocessor

Have a Harbor Breeze "Slinger" 72 in fan, microprocessor controlled, I believe. The mains switch that includes the circuit the fan is wired into was turned off to replace a light fixture on the same circuit. Ordinarily, after losing power, this fan goes through a series of short back and forth blade gyrations before resuming normal operations.Yesterday, that did not happen. The fan went through the gyrations, but then stopped. The fan light operates properly. Multiple efforts were expended in an attempt to get the fan operating properly, without success.

I just bought a house and I found out it has a 2 wire system

I just bought a house and I found out it has a 2 wire system outlet (no ground wire) on every outlet in my bedrooms and living room. And now it won't pass inspection without getting fixed. So, I was wondering, can I replace the old outlet with AFCI outlets or would it be easier to just add AFCI breakers on those circuits?

I have a single gang, single pole double switch. The top

I have a single gang, single pole double switch. The top switch controls a switched outlet, the bottom switch controls lights. I'd like to install two smart switches in place of the double switch. The smart switches require a neutral.There are two sets of 2 conductor wires (Romex 1 and Romex 2) that come from the wall. The current wiring for the double switch is as follows:-Black cable from Romex 1 spliced to top and bottom terminals of double switch provides power.-White cable from Romex 1 has electrical tape on it and seems to provide switched power to lights is connected to bottom left terminal of double switch.-Black cable from Romex 2 connects to top left terminal provides switched power to switched outlet.-White Cable from Romex 2 is capped off and not used.-Grounds cables are tied together, but not connected to switch.I'm not sure if the current is correct or safe. Is there any way for me to connect the two smart switches?

Dear Pearl, I am in the Dominican Republic. I have two 110

Dear Pearl,JA: I'll do all I can to help. How long have you been dealing with this?Customer: I am in the Dominican Republic. I have two 110 lines. I would like to protect the 220 V pump of the swimming pool. Do I need two CHSPT2Max surge protectors? One for each hot line?JA: Do you plan on doing the work yourself?Customer: Sure, I am in a small village and there are no qualified electricians here. I am Dutch.JA: Anything else we should know to help you best?Customer: Yes, the situation is a bit complicated.We have 14 hours current from the street line. Mostly during the night. In the night an inverser is changing the batteries and during the day the inverser provides electricity in the house. The pump of the swimming pool is heavy for the inverser and only works during the time there is electricity from the 'street'. The quality of the electricity is low and there are a lot of fluctuations. I have a new 2 pole circuit breaker. Is this for only one hot line?JA: How old is the system in question? And have you consulted an electrician yet?Customer: Part of the system is 15 years old, other part have been added last 3 years. It is difficult to find a qualified electrician. I tried several, but ithe system is a mess compared to a system in Holland.

I have tried several wiring combinations and my lights do not turn onJA: How old is the system in question? And have you consulted an electrician yet?Customer: I may have to bring in an electrician. The apartment had been renovated recently by the building owner. I don't know if the Load wire is a requirement for this Leviton Decora Smart switch. Currently, the lights work fine with the installed single pole switchJA: Do you plan on doing the work yourself?Customer: Installing the switch yes. adding an additional wire, I think is beyond my capabilities.JA: Anything else we should know to help you best?Customer: The installation of the decora smart switch is pretty straightforward. I just need help troubleshooting it so that the lights turn on when I turn the circuit breaker back on.
