Burning Smell from an Electrical Panel? Here’s What We Found

A homeowner recently contacted us because their air conditioner kept shutting off intermittently. Sometimes the AC would run normally, other times it would stop working entirely.

They also noticed something much more concerning.

They reported:

• The AC breaker was tripping repeatedly
• They could hear sizzling and crackling coming from the electrical panel
• There was a burning smell near the panel

Any time you hear noise or smell burning from an electrical panel, it should be inspected immediately.

What We Found Inside the Panel

When we opened the electrical panel, the cause became clear.

The breaker feeding the air conditioning circuit had severely overheated at the wire terminal.

The connection had burned to the point where:

• The conductor insulation was damaged
• The breaker terminal was carbonized
• The breaker body had partially melted

When a connection deteriorates like this, the breaker can no longer maintain a solid electrical connection with the wire. Instead, the connection begins to arc and generate heat.

This explains the sizzling sound, burning smell, and intermittent power to the AC system.

If ignored, this type of overheating can eventually lead to:

• Repeated breaker trips
• Loss of power to equipment
• Damage to the electrical panel
• Electrical fire hazards

What Causes Breaker Connections to Burn Up?

Several issues can lead to overheating at a breaker connection.

Loose electrical connections

If the wire terminal is not properly torqued when installed, it can loosen over time. Even a slightly loose connection creates resistance and heat.

High electrical loads

Large appliances like air conditioners draw significant power, especially during compressor startup.

Aging breakers

Over time, breaker terminals and internal components can degrade, creating poor contact.

Heat buildup over time

Once a connection begins overheating, the problem can escalate quickly as resistance and heat increase.

How We Fixed the Problem

To safely restore the circuit, we performed the following steps:

• Removed the damaged breaker
• Inspected the panel bus bars for damage
• Cut back the burned conductor to clean copper
• Installed a new properly rated breaker
• Torqued the connection to manufacturer specifications
• Tested the circuit to confirm normal AC operation

Once the repair was complete, the air conditioning system operated normally without tripping.

Warning Signs You Should Never Ignore

Electrical panels should never make noise or smell like something is burning.

If you notice any of the following symptoms, it’s important to have the system inspected right away:

⚠️ Breakers that trip repeatedly
⚠️ Burning smells near the electrical panel
⚠️ Crackling or sizzling sounds
⚠️ Warm breakers or panel covers
⚠️ Intermittent power to appliances or HVAC systems

These symptoms often indicate overheating electrical connections, which can quickly become dangerous.
