Samsung Refrig needs to be reset after any power outage HELP!
Comments (39)In Reference to my comment 7 months ago about the Samsung Refrigerator not powering back up after a neighborhood power outage- it happened again this weekend while we were out of town- storm apparently came through the area, downed tree limbs knocked out power to the neighborhood on Saturday. We were planning to come home this Monday but after learning about the outage via Facebook came home Sunday and sure enough - 2 year old Samsung -no power, 15 year old Kitchenmaid and 20 year old Amana humming along no problem. If ANYONE knows of a solution or has been successful dealing with Samsung on this issue please let us know!!! I'm calling again now but not confident- will update blog if any success....See MorePower outages and freezers
Comments (35)As a matter of fact, in a different situation, you are encouraged to back feed to grid if you have a solar cell or wind generator electric system. We have a whole house PV and battery back-up system. You wouldn't believe the amount of trouble we had to go through to ensure "island protection". That's what our utility calls the situation when your household (or your neighborhood) becomes temporarily isolated from the rest of the grid. It's now an island that has its own uncontrolled and unsynchronized power ... everything is fine, until somebody tries to connect it back to the rest of the grid. When that happens, you'll see fireworks. Both sides of the grid are almost certainly out-of-phase. And that causes huge surges. These surges won't stop until something burns out and disconnects the generator. So, no, you are never encouraged to directly feed back into the grid. The only times you would do this, there is a fancy control circuit in line that carefully checks whether it is safe to do so. And unless this circuit can 100% verify that it is safe to backfeed, it'll instead disconnect your house from the grid. Think of it as a transfer switch on steroids. For PV systems, it's typically integrated with the inverter. For battery backup systems, it's usually a separate component. That's also the reason why PV systems, as a rule, cannot power your house during a power outage. There is no safe way to do this unless you also have backup batteries and additional safety equipment....See MoreTurn off AC before approaching storms & brief power outages?
Comments (7)In order to fully protect a piece of equipment (any electrical equipment) from the likes of a possible near by lightning strike -- the path in which it is connected to your electric panel must be 'interrupted'. If the appliance is a plugged appliance - pull the plug. TV's, computers, refrigerator, freezer etc (anything that is plugged in). HVAC - shut off / pull disconnect / then shut off breaker to furnace (AC and furnace are on separate breakers). Ideally the only thing that should be left on is lighting. Most electric panels aren't marked, if yours is -- another way would be to go to the electric panel and shut off power from things there. Only if your house suffers a direct lightning strike would you suffer damage with circuit shut off but things still plugged in to wall outlet. Under a direct hit the lightning will take the least resistance pathway to ground. In some cases that will probably cause damage to anything connected to your electric supply in your home. ------- With that said doing this you only slightly reduce the chances of electrical damage. Why? because voltage fluctuates on the grid. The grid operator is continually adjusting things and maintaining that grid so it functions normally. This is typically more of a challenge during electrical storms, but it also can be challenging under high load / heavy use events. See Brown Outs / Power surges ----- these events happen all of the time. Direct electric strikes are devastating, but they are relatively rare. Over the course of my career I've visited about 3 such homes that the damage was likely from a 'near by' lightning strike event. The damage varies when it comes to HVAC. -- typically electronics are the most vulnerable....See MoreMinnesota power outage: pipes
Comments (5)If you know what you are doing and have the tools, you can winterize your plumbing by draining it down, putting anti-freeze in the traps, etc. That's a lot to ask from a homeowner though. Keep the house closed as much as possible, close blinds and such to retain as much heat as you can. You don't need it to be warm... just not way below freezing. Then run a pencil stream of water from all of your faucets including a mix of hot and cold. The running water will be less likely to freeze because it's being replaced by water that's above freezing. Flush your toilets every couple hours to keep the traps from freezing. If you have a gas stove, turn on a burner or two. You will have to light it with a match since the igniter won't work. Keep anything flammable away from the stove. Don't overdo this though - just run a couple of burners at a time....See More- 11 years agolast modified: 11 years ago
