What makes the plug of an Air Conditioner get hot?

The common problem that may cause the plug of an Air Conditioner to hit is the overloaded circuit. The pin will struggle to energize the machine, getting overworked and eventually gets hot. With such plugs, touching the hot part is not recommended; you could easily get burnt.

Damaged or loose wiring. This issue primarily arises when there’s heat buildup in any electrical outlet. So when plugging the Air Conditioner, you will realize some sorts of spark bursts. This is an early warning then your unit’s wiring is defective or the cord isn’t in excellent condition.

Sparking Outlets

Damaged Air Conditioner outlets or plugs may be problematic when developing a reliable connection. This will eventually increase the risks of the faulty fuse or sometimes tripping the unit’s circuit breaker. Therefore, a faulty circuit breaker or blown fuse of your Air Conditioner will make the plug too hot to touch.

Regular plug-in-and-plug-outs. This is another issue that happens mostly when the plug is over-utilized. The issue applies similarly to light switches; faulty wirings can be the real issue here. Regular plugging and disconnecting the cord from your Air Conditioner will eventually kill the plug; it will be worn out sometimes.

Dimmer switches. Sometimes the plug of your Air Conditioner may get hotter than expected with dimmer switches. It’s therefore advisable that you use the compatible plug-ins as recommended by the manufacturer. Besides, you should learn about the acceptable or recommended temperatures, but it is advisable to diagnose the issue yourself or seek contact with a certified electrician if the problem persists.

How to fix the Overheating plug issue in your Air Conditioner

Even though fixing the faulty AC plug should be rendered for an experienced electrician, it’s possible to attempt a simpler changer by yourself. I repeat, more straightforward defects; it will spare from unsafe situations.

So, before calling an expert, configure the issues and try to fix them out with the aid of the following guide:

Inspect the wiring of your AC plug

I thought you should know that damaged or loose wiring can cause the plug of your Air Conditioner unit to overheat, eventually becoming a fire hazard. Due to natural wear and tear, the pin of your air conditioner may become problematic. It’s therefore advisable to have your unit checked together with its wirings.

An experienced electrician will employ thermal, electrical imaging, and inspections on an Art plumbing, Electric, and AC for prior faults in your AC system.

Avoid using multiple power strips

When a specific power outlet is energizing multiple strips, there is a high chance that the energy load will be too massive for the plug to accommodate. Therefore, it’s advisable to connect your AC unit to a different power outlet around your house or home. It’s recommendable because a single socket can be underpowered to energize the required power at a time.

Check for defaults arising from the AC Unit

Sometimes the issue might come from the multiple electrical appliances in our homes. Experts, therefore, recommend checking the condition of the AC’s charger to ensure it’s not problematic.

It’s necessary that some unit’s chargers act like transformers to adjust the voltage required by the air conditioner. If the plug is hot, the electrical outlet can get damaged, ensuring that the appliance’s wiring is correct.

  2. You should use the pigtail method when wiring the outlets of small air conditioners. It would help if you prevented the wires from getting joined to the outlet via the push-in attachments. Instead, the cables must be connected through the screw terminals.
  3. All the terminations and circuit wiring should be tight and snug.
  4. Loose wiring links may trigger heating, arching that eventually leading to a deteriorated or burnt connection; it can also lead to circuit failure.
  5. Primarily, house fires break due to an overburdened electrical circuit that gets overheated.
