Trying to find out how I've lost power to a circuit without tripping the breaker


STEP 1 TEST WITH A MULTI METER THAT THE UNIT IS GETTING VOLTAGE FROM BREAKER POWER LINE IN BE CAREFUL AND IF YOU DO NOT KNOW HOW TO USE A VOLTAGE METER GIVE IT UP

IF THE UNIT IS GETTING AC 120 VOLTS IN THEN CHECK THE DC TRANSFORMER FOR DC VOLTAGE WHICH SHOULD BE 12 OR 24 VOLTS AND THE CONVERTED SIDE OF THE TRANSFORMER

Frigidaire - Professional Series - Gas/Electric Range - Replaced bake element but now Broiler and Bake elements don't work


Go outside to the breaker panel on your house and reset the oven breaker a couple of times. It will be 2 breakers side by side with the switch handles bound together. What happens is if one trips but not both, 240 volts is not present but 120 is. that's why motors and lights still work. If the breaker has some age on it just get the number off it and replace it.

Outlets not working all fuses are good


120-
VOLT
AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

SECTION 6 - ELECTRICAL SYSTEM JAYCO TOWABLE
6-2
120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

Power outage. Turned fuse box back on 24 hours still no hot water


We have situations like that where even with an electrical meter it may appear that both sides of the panel have voltage when actually one of the main breakers or fuse has blown. If that is the case power flows through some 220 volt devices to feed the second side of the panel but no 220 volt appliances work. If that is the case then the voltage will not be 120 volts on the second side but some lighting has a brown out or too low of a voltage. If none of this is happening then you have blown your element. To prove that... verify with a multimeter that you have 220 volts on the element.

Have a 2004 taurus.no owners manual. cig lighter fuse blew,dont know which one it is.


Fuses, Switches, Circuit Breakers And Relays Most vehicles use one or more fuse panels. This one is located on the driver’s side kick panel tcca6p01.jpg

It is possible for large surges of current to pass through the electrical system of your vehicle. If this surge of current were to reach the load in the circuit, this surge could burn it out or cause severe damage to the vehicle’s electrical system. It can overload the wiring, causing the harness to get hot and melt the insulation. To protect vehicle wiring, fuses, circuit breakers and/or fusible links are typically installed into the power supply wires throughout the electrical system. These items are nothing more than a built-in weak spot in the system. When an excessive amount of current flows through a circuit it causes an increase in heat throughout the wiring. Fuses and circuit breakers are designed as the weak link in the system and will disconnect the circuit to prevent damage to the components contained within that circuit. Components are equipped with connectors so they may be replaced in situations where they were damaged due to a power surge.
The following are descriptions as to how fuses and circuit breakers protect the electrical system:
  • Fuse- A fuse is a weak link in the system designed to create an open circuit when the amperage flowing through that circuit exceeds the limits of the fuse. As the amperage increases, the conductor within the fuse heats up and eventually melts and breaks apart. This open circuit interrupts the flow of current and protects the components in the circuit.
  • Circuit Breaker- A circuit breaker is a "self-repairing" fuse. It will open the circuit in the same fashion as a fuse. The surge creates heat the same way that a fuse is affected. When the surge subsides and the circuit cools down, the circuit breaker will reset and allow current to flow through the circuit. Typically circuit breakers do not need to be replaced.
  • Fusible Link- A fusible link (fuse link or main link) is a short length of special, high temperature insulated wire that acts as a fuse. When an excessive electrical current passes through a fusible link, the thin gauge wire inside the link melts, creating an open to protect the circuit. To repair the circuit, the link must be replaced. Some newer type fusible links are housed in plug-in modules, which are simply replaced like a fuse, while older type fusible links must be cut and spliced if they melt
CAUTION
Always replace fuses, circuit breakers and fusible links with identically rated components. Under no circumstances should a protection device of higher or lower amperage rating be substituted.

I would get a fuse tester that can test fuses while still installed and powered up. It will light if the fuse is blown when applied to the two tabs that are exposed on fuses that are installed in your Ford product.

Check the fuse box under the dash on the driver's side, and check to see if there are any fuses under the hood.

If you don't have the tool, try to look for stickers or download the manual from ford.com.

Power windows wont work what fuses can i check i have replaces the driverside switch.


Fuses, Switches, Circuit Breakers And Relays
Check under hood and under the dash driver's side.
There may be a sticker on the inside of the panel cover that tells you the legend. Otherwise, it requires testing each and every one of those fuses, preferably with a fuse tester that can do it more expediently than pulling each one out and looking for a broken conductor.

CAUTION
Always replace fuses, circuit breakers and fusible links with identically rated components. Under no circumstances should a protection device of higher or lower amperage rating be substituted.
Switches Switches are used in electrical circuits to control current flow. The most common use of relays and switches is to open and close circuits between the battery and various electrical loads in a circuit. loads are rated according to the amount of amperage they can handle. All of the current that the controlled load uses flows through a switch. Using a switch with an amperage rating lower than what the circuit is rated for could overload and cause damage to the components located on that circuit. Relays
The underhood fuse and relay panel contains fuses, relays, flashers and fusible links tcca6p02.jpg

Relays are used to control high-current loads with lower currents. Since these some loads require a large amount of current, the thickness of the wire in the circuit is also greater. If a switch were used to control the circuit, all of the current required to power the high-current load would have to pass through the switch. From a design standpoint, relays are used to limit current through switches and reduce the amount of heavy gauge wiring in the vehicle.
Relays are constructed of a set of switch contacts and a small electro-magnetic coil. When current flow through the coil a magnetic field is created. This field causes the contacts to touch, in turn completing the high-current circuit. Typically, relays are constructed so that the secondary contacts are open when the relay is de-energized (turned off). Circuits where relays are used include, but are not limited to, the horns, headlights, starter motor, electric fuel pump, blower motor and cooling fan motor.
Relays are composed of a coil and a set of switch contacts. The large wires connect a high current power source to one side of the relay switch contacts and from the other side of the relay switch contacts to the load. The smaller wires connect a low current power source to the relay control coil and from the control coil to the control switch and then to ground. tcca6g02.gif

Load Every electrical circuit must include a "load'' (something to consume voltage from the power source). Loads are resistances included in circuits to limit current flow. Loads are the components installed in circuits, such as headlights, wiper motors, door lock solenoids. Without a load, the battery would flow all of its energy through a circuit directly to ground. This is called a "dead-short to ground". The unchecked flow of electricity would cause a great amount of damage to the circuit by developing a tremendous amount of heat. Short circuits can develop sufficient heat to melt the insulation of surrounding wires, even reducing a multiple wire cable to a lump of plastic and copper.

We had a power surge now when i plug my fridge in it blows my circuit breaker


The power surge might have damaged the wiring to the refrigerator. You can check this one with a megar. That is only if the circuit breaker blows off, ONLY when the unit is turned on. Else, the problem may be that current is flowing through the neutral. You can check it with a tester and if so, report it to the electricity board. Else, as a temporary measure, you can connect your unit, bypassing the circuit breaker. But in that case the circuit breaker will never blow off regarding any complaints to the unit and may result in a slight power wastage.

Sound but no picture


Hello,

Also, you might have gotten a power surge, or a power spike. This can also occur without a lightning storm. Sometimes through your power eletric provider.

A power surge, or transient voltage, is an increase in voltage significantly above the designated level in a flow of electricity. In normal household and office wiring in the United States, the standard voltage is 120 volts. If the voltage rises above 120 volts, there is a problem.

Of course though, Just trying to help.

LER4634E WHIRLPOOL FRONTLOAD ELECTRIC DRYER WORKED GREAT


If you have a access to an AC voltmeter, measure the two slanted connections in the wall socket for ~220 volts. If near zero, measure at the load side of the dual breakers for the same voltage. If still at or near zero, one of the breakers has gone south. Replace the pair of breakers.
If you measured 220 volts as above, then the problem is within the dryer--probably a burned out heating element or open thermal fuse. Major tear-down to find and fix as the heating element is behind the drum.
