220V / 240V Wiring Troubleshooting & Repair in Brick, NJ
Some of the most important equipment in your home runs on high-voltage circuits: electric dryers, ranges and ovens, central air conditioning, heat pumps, water heaters, pool and spa equipment, and EV chargers. These circuits are commonly called 220-volt, and in modern homes they are technically 240-volt. Either way, when something goes wrong on a high-voltage circuit, you will notice, and it is not a good time to improvise.
Light Up Electric LLC diagnoses and repairs 220V and 240V wiring problems for homes across Brick and the Ocean and Monmouth County shore.
HIGH VOLTAGE ELECTRICAL SERVICES
Is it 220V or 240V?
You will hear both terms. Residential service in the United States is delivered as 240 volts between the two hot legs, and 120 volts from each leg to neutral. “220V” is an older, colloquial name that stuck. When you search for a 220V outlet or 240V circuit repair, you are looking for the same type of work: a two-pole circuit with a matching breaker, wire size and receptacle.
Symptoms of a 220V/240V problem
High-voltage circuit trouble often looks different from ordinary outlet trouble. Watch for these signs:
- A dryer that runs but does not heat, or heats weakly
- An electric range or oven where some elements work and others do not
- An air conditioner, heat pump or water heater that suddenly stops
- A two-pole breaker that trips repeatedly or will not reset
- Appliances that run at half power or behave oddly
- A burned, discolored or melted receptacle or plug
- Buzzing, warmth or a burning smell at an outlet or panel
- Lights that dim sharply when a large appliance turns on
Many of these are caused by a loose connection, a failing breaker, a worn receptacle or a mismatched wire and breaker. A single dead leg on a 240-volt circuit can make an appliance appear partly broken when the real problem is in the wiring.
How we troubleshoot
We start with safety. High-voltage circuits can deliver serious shocks, so we de-energize and verify before touching anything. Then we test voltage at the panel, the receptacle and the appliance, check the breaker and the wiring path, and inspect connections for heat damage. Once we find the cause, we explain it and give you a firm price before any work begins. If the appliance itself is at fault, we will tell you so, rather than replacing parts that are not broken.
Common fixes
Depending on what we find, a solution can include:
- Replacing a failing two-pole breaker
- Replacing a worn or heat-damaged receptacle or plug
- Repairing loose or damaged conductors
- Correcting undersized wire or a mismatched breaker
- Updating older 3-wire dryer or range circuits to current 4-wire standards when appropriate
- Installing a new dedicated circuit for a new appliance
- Adding surge protection to guard HVAC and appliance electronics
Upgrading, adding or relocating circuits
Many homeowners call because they are adding something new: a heat pump, a hot tub, a workshop welder, a second range or a Level 2 charger. We evaluate whether your panel has the capacity and whether the existing circuit is suitable. If you are planning a Level 2 charger, see our EV charger installation service. If your panel is full or aging, an electric panel upgrade may be the right first step.
Code compliance and safety
High-voltage work should meet current electrical code, with correct wire gauge, breaker sizing, grounding and connection methods. Improper work can overheat, damage appliances or create a fire hazard. We install and repair circuits to code, pull permits and handle inspections ourselves when required, and test every circuit before we leave.
When to call right away
A burning smell, melted plug, visible sparking or a hot panel cover should be treated as urgent. Stay clear of water, shut off power if it is safe, and call 911 for fire. For urgent electrical problems, see our emergency electrician service; after-hours calls carry an additional fee, quoted up front. For less urgent issues, our general electrical repair team can also help.

Frequently Asked Questions
Is 220V the same as 240V?
For homes, essentially yes. Residential service is 240 volts across two hot legs, and “220V” is the older term still widely used. The circuits, breakers and receptacles are the same type of two-pole system.
Why is my dryer running but not heating?
It is often caused by a failed heating element or thermal fuse in the dryer, or by a problem on one leg of the 240-volt circuit, such as a bad breaker or loose connection. An electrician can test the circuit to find out which.
Why does my two-pole breaker keep tripping?
Causes include an overloaded or failing appliance, a loose or damaged connection, a worn breaker, or a wiring fault. Repeated tripping should be inspected rather than reset over and over.
Can I use my dryer outlet for an EV charger?
It depends on the outlet, the wire, the breaker rating and the charger. Some dryer circuits are not suitable for continuous EV charging. We evaluate the circuit and recommend a safe solution.
Do I need a permit for 220V or 240V circuit work?
New circuits generally require a permit and inspection in New Jersey, and some repairs do as well. We determine the requirements for your job and handle the permit and inspection ourselves.
When should I call an electrician instead of an appliance technician?
If the appliance’s own parts are fine but it does not get proper power, or you notice burning, buzzing, melted plugs or tripping breakers, the issue is likely in the wiring or breaker, and an electrician is the right call.
