All circuit breakers good in box. have no power to 3 rooms on outlets or lights . problem started when using a hair dryer hooked too a drop cord in a outlet

You omitted to say whether your "mains" is supplied by inverter, generator or mains hook up?

If there is no power at the outlet(s) and the breakers are ok then either there is a break in the wiring or no power is being supplied to the breaker box.

I suggest you check your supply and if ok, check the wiring to the breakers and outlets for continuity...

dead short internally or bad wiring in the cord
cord can be replaced by electrician but otherwise junk it and get a new one

The recommended power cord is a 30 amp 3- or 4- wire cable. A 50 A cord could cause a problem by allowing a surge to the dryer motor and damage the dryer or start a fire. There are 30A to 50A adapters (see RV and boat supply vendors). The installation instructions for the LER5636EQ3 are available here: https://www.whirlpool.com/digitalassets/MLPDF/Installation%20Instructions%20-%203397618.pdf . See page 5 of the PDF.

Note: the 50A outlet has a 50A circuit breaker protecting it. If you swap the outlet to a 30A outlet, you will also need to replace the breaker with a 30A one.

I hope this helps.

If there is not lights or anything in the refrigerator, then you aren't getting power. Start out checking the outlet - if you don't have a multimeter to check it, use a hair dryer plugged in to that outlet to see if it will work. If it doesn't then it is between that outlet and the main circuit breaker box or even a bad circuit breaker.

If it does work or you have lights in your refrigerator it is probably either the starting capacitor, start relay or compressor.

LG refrigerators are more sensitive to power fluctuations than other models and we have had to replace a lot of starting caps and relays - but sometimes it is the compressor.

Hope this helps!

Hi, these ground fault Interupter or AFCI breakers are made for normally outdoor circuit and and circuits around water such as your bathrooms. I would turn each one off, take a screw driver and make sure each terminal to each breaker is good and tight. You say this is a new home, so it makes since this is a problem. This can be done safely, as with the breakers off the screw terminals are dead, always be safe though when working around high voltage. If you continue to have this problem, you would have no other choice than to get a qualified Elect. out to see if they have your G.F.I breakers wired on the right circuits? This sounds to me this also may be your problem. They are made to trip around sinks with lets say your lady of the home using a blow dryer on her hair and there is a slight voltage leak in the cord of the appliance? This is when the breaker should trip due to the chance of shock!!

Please check the circuit breaker fuses. The one in your bedroom is of lower amps. If it is 5 amps replace it with 15 amps. Also check the connections of the socket. It could be that wires there are not connected with the socket or they are burnt out thus no connection.

While there is a practical limit for the number of outlets on a 15 or 20 amp general purpose lighting circuit in a _residence_, the National Electric Code (NEC) does not impose a # of outlets per circuit limit (residential ONLY).
However, some electrician's design general purpose lighting circuits in a residence using a point system. An outlet is 2 points and a light is 1 point. So, for a twenty amp circuit, (10 outlets x 2 points) = 20. Or, (5 outlets x 2 points) + (10 lights x 1 point) = 10 + 10 = 20. Or (8 outlets x 2 points) + (4 lights x 1 point) = 16 + 4 = 20. However you want to mix it up.

Now, if this is for a Commercial building, the the NEC allows no more than 180 VA (Volt Amps) per outlet. 180 VA / 120 Volts = 1.5 Amps.
20 amps / 1.5 Amps = 13.3 outlets. Drop the .3 and one determines that 13 outlets are allowed on a Commercial 20 amp circuit.

Also, if the 20 amp circuit is considered a continuous circuit (ON for more than 3 hours a day), then it can only be loaded to 80%. 80% of 20 amps = 16 amps.

hi. I can help you.

Electric dryers use 220 volts or two power lines of 110 volts each. Some components in the dryer need only 110 volts; the heating element requires 220 volts. So it's possible for one part of the dryer to be fine and another part to have a short circuit. Short circuits can be caused by the heating element, the main power cord, or any other part of the internal wiring. To decide where the problem lies, unplug the dryer, then:

• If the circuit breakers or fuses remain on and/or intact when the dryer is unplugged, it's likely the problem is with the dryer. Contact a qualified appliance repair technician.
  
  
• If the circuit breaker trips or the fuse blows when the dryer is unplugged, it's likely the problem is with the house wiring, fuse box, or circuit box. Contact a qualified electrician.
  

your dryer may not be recieving adequate voltage to start.
make sure your dryer is plugged in.
also check the circuit breaker panel to make sure all circuit breakers are in the right position.
check fuse box for blown fuse.
try plugging in something else in the same outlet.
also refrain from using an extension cord.

On the 40 amp breaker, you should be using 8-3 w/ground. 10-3 w/ground will work on the 30 amp breaker. 12-3 w/ground is used for 20 amp circuits. Your new heater should have the electrical requirements listed in the user/installation information.
