Brief Overview of AC Compressor Over Amping
Picture an AC compressor working harder than it should, drawing more electrical current than it’s designed to handle. That’s over-amping. It’s like a small car trying to tow a huge trailer. It’s bound to struggle and eventually wear out, right?
Understanding AC Compressor Over Amping
Let’s break down over-amping, why it’s a threat to your AC compressor and the leading causes that push your system over the edge.
The Concept of AC Compressor Over Amping
The electrical world can be a complex place. But here’s the scoop: over-amping is when an AC compressor uses more amperage than it’s rated for. The result? A strained compressor that could break down.
What Over-Amping Means in AC Compressors
It’s like this: your AC compressor is the heart of your air conditioning system. AC compressor over amping is like having this heart beat way too fast. It may keep things cool for a while, but this over-exertion can cause serious long-term damage.
The Causes of AC Compressor Over Amping
The reasons behind AC compressor over amping often boil down to three main culprits: electrical faults, mechanical issues, and refrigerant problems. It’s crucial to identify which one is affecting your AC to take corrective action.
Electrical Faults
Remember, your AC is a complex piece of machinery. Issues like a short circuit, wrong wire size, or even power supply variations can lead to high amps in your AC compressor.
Mechanical Issues
Imagine your AC compressor as a well-oiled machine. When parts become worn out or fail, the entire system has to work harder. It’s like running a marathon with a sprained ankle. This can lead to over-amping.
Refrigerant Problems
Just as your car needs the right amount of oil, your AC compressor needs the correct amount of refrigerant. Too much or too little can cause over-amping. It’s a delicate balance, indeed.
Recognizing Signs of AC Compressor Over Amping
Identifying over-amping early can save you from more significant issues. Here, we’ll discuss the telltale signs you can spot visually and through your AC’s performance.
Visual Indications
Keep an eye on your AC compressor’s physical state. Look out for signs of electrical damage or heat that might suggest over-amping.
AC Compressor Physical Appearance
Believe it or not, you can often spot signs of over-amping just by looking at the compressor. Think of burnt wire connections, darkened parts, or even melted insulation. It’s a sight you wouldn’t want to see, trust us.
Signs of Electrical Damage
Another telltale sign is electrical damage. If you notice tripped circuit breakers or blown fuses, you might have an over-amping compressor on your hands.
Performance-Based Indications
Changes in your AC’s cooling efficiency and operation could be your compressor crying out for help. Stay alert to any inconsistencies.
Changes in Cooling Efficiency
Ever noticed your home isn’t as cool as it used to be? This could be due to an over-amping AC compressor. Remember, when the compressor struggles, it can’t cool as effectively.
Inconsistent Operation of the AC System
Over-amping can also cause your AC system to run inconsistently. It’s like driving with a flat tire – you can go on for a while, but you’re not going anywhere fast.
Testing an Over-Amping AC Compressor
It’s time to don your DIY hat and learn to ohm out your AC compressor, a handy skill that can save you a service call.
How to Ohm Out an AC Compressor
Let’s demystify the process of ohming out your AC compressor. It’s simpler than you might think and a key step toward identifying potential issues.
Understanding Ohm Measurements
Feeling confused by Ohm measurements? Think of it as a way to measure the resistance in an electrical circuit. When ohming out an AC compressor, you’re checking if there’s too much or too little resistance, both of which can cause problems.
Step-by-step Guide on How to Ohm Out an AC Compressor
Ohming out an AC compressor helps you measure the resistance within the compressor’s electrical circuits. It’s a technical process, but with a few tools and this guide, you can do it yourself.
First, you need a multimeter, a device used to measure electrical properties such as voltage, current, and resistance. You can find one at a hardware store or online.
For safety reasons, ensure your AC unit is disconnected from the power source before you begin.
Locate the compressor terminal, usually found under a cover at the side of the compressor. The terminal will have three pins, labeled S (start), R (run), and C (common).
Set your multimeter to measure resistance, which is measured in ohms (Ω).
Now, touch one multimeter lead to the “S” pin and the other to the “R” pin. Write down the resistance measurement.
Repeat this process for the “S” and “C” pins, and the “R” and “C” pins. You should now have three measurements.
The resistance between the “S” and “R” pins should be lower than the other two measurements. The resistance between the “S” and “C” pins plus the resistance between the “R” and “C” pins should approximately equal the resistance between the “S” and “R” pins. If it doesn’t, your compressor might have a short or open winding, indicating a problem.

Responding to AC Compressor Over Amping
Now that you’ve identified and tested for over-amping, it’s time to learn about the appropriate response measures to bring your AC compressor back to normal operation.
AC Compressor Overload Reset
An AC compressor overload reset could be the quick solution you need. Let’s discuss what it involves and how to do it right.
The Role of the Overload Protector
Did you know that your AC compressor has an in-built safeguard called the overload protector? It’s kind of like a bodyguard, stepping in when things get too hot and shutting the compressor down to prevent damage.
How to Reset an Overloaded AC Compressor
If your AC compressor is overloaded due to over-amping, a reset might help. Overloads happen when the compressor works too hard, leading to overheating and potential damage. To protect the compressor, most units come with an overload protector that cuts off power in such situations. Here’s how you can reset it:
Make sure your AC unit is disconnected from the power source. Safety first!
Locate the AC compressor. It’s usually found outside your home in the condenser unit. The compressor is the large, cylindrical part.
Look for the compressor’s overload protector. It’s often a small box or button.
Press the reset button on the overload protector. Some protectors automatically reset after cooling down, so if there’s no reset button, just wait a while.
After resetting, reconnect the power and monitor your AC compressor. If it’s still not working correctly, or if the overload protector trips again, you might have a more serious issue on your hands that may require professional help.
When to Seek Professional Help
There are situations when a professional touch is necessary. Learn to recognize these instances and understand how to choose the right AC technician.
Situations That Require Expert Attention
Not all issues can be fixed at home. If your AC compressor keeps over-amping or if you’re unsure about any of the steps, don’t hesitate to call a pro.
Choosing a Reliable AC Technician
Need to find a reliable AC technician? Look for someone with good reviews, appropriate licenses, and solid experience. Remember, it’s about trusting someone with the heart of your AC system.
