Why Does My Space Heater Cord Get Hot? The Electrical Hazard You Need To Know

Space heaters are a lifesaver during chilly winters, providing warmth and comfort. However, if you notice your space heater cord getting hot, it’s crucial to investigate the underlying causes to ensure safety and prevent potential hazards.

Electrical Overload

One of the most common reasons for a space heater cord getting hot is an electrical overload. This occurs when the heater draws more electricity than the cord is rated for. The excessive current flowing through the cord generates heat, causing it to overheat.

Symptoms:

• The cord feels unusually warm to the touch.
• The cord may emit a burning smell.
• The circuit breaker or fuse may trip frequently.

Remedies:

• Ensure the space heater is plugged into a properly rated outlet.
• Avoid using extension cords or power strips with the space heater.
• Check the wattage of the space heater and make sure it’s compatible with the outlet.

Loose Connections

Loose connections between the cord and the space heater or outlet can also cause the cord to overheat. When the connections are not secure, arcing occurs, creating excessive heat.

Symptoms:

• The cord feels warm at the connection points.
• The space heater may flicker or turn off intermittently.
• You may hear a crackling or buzzing sound at the connections.

Remedies:

• Inspect the connections at both ends of the cord.
• Tighten any loose screws or terminals.
• If the connections are damaged, replace the cord or have it repaired by a qualified electrician.

Defective Cord

In some cases, the space heater cord itself may be defective. This could be due to a manufacturing flaw, wear and tear, or damage.

Symptoms:

• The cord shows signs of fraying, cracking, or discoloration.
• The cord feels unusually stiff or brittle.
• The space heater may not operate properly or may turn off abruptly.

Remedies:

• Immediately discontinue use of the space heater.
• Replace the cord with a new one that meets the manufacturer’s specifications.
• Have the space heater inspected by a qualified electrician to identify any other potential issues.

Overheating Space Heater

If the space heater itself is overheating, the cord may also get hot as a result. This can occur due to various factors, such as:

• Blocked air intake or exhaust vents.
• Dirty or clogged filters.
• Oversized space heater for the room.
• Improper placement near flammable materials.

Symptoms:

• The space heater feels excessively hot to the touch.
• The heater emits an unpleasant odor or smoke.
• The heater may shut off automatically due to an internal safety mechanism.

Remedies:

• Clear any obstructions around the air intake and exhaust vents.
• Clean or replace dirty filters.
• Ensure the space heater is appropriately sized for the room.
• Keep the heater away from curtains, furniture, and other flammable objects.

Other Causes

In rare cases, other factors may contribute to a hot space heater cord:

• Faulty thermostat: A malfunctioning thermostat can cause the heater to overheat.
• Voltage fluctuations: Power surges or drops can put additional strain on the cord.
• Damaged outlet: A damaged outlet can create loose connections and overheating issues.

Safety Precautions

If you notice your space heater cord getting hot, take the following safety precautions:

• Unplug the space heater immediately.
• Allow the cord to cool down completely.
• Inspect the cord and connections for any damage.
• If you are unable to identify the cause or resolve the issue, contact a qualified electrician.
• Never use a space heater with a damaged cord.

Next Steps

Once you have identified and resolved the cause of the hot space heater cord, it’s important to take the following steps:

• Use the space heater according to the manufacturer’s instructions.
• Regularly inspect the cord and connections for any signs of damage.
• Clean or replace the filters as recommended.
• Ensure the space heater is placed in a well-ventilated area away from flammable materials.

Avoiding the Hot Cord

By understanding the causes of a hot space heater cord and taking appropriate precautions, you can prevent potential safety hazards and ensure the safe and efficient operation of your space heater. Remember, it’s always better to err on the side of caution and address any concerns promptly.
