High amperage draw on your air conditioning system can be caused by several different things. Here are a few common causes of high amperage:
One of the most common reasons for high amperage draws is a high head pressure. This happens when the condenser coil gets dirty or blocked and cannot efficiently cool down the refrigerant gas. The higher temperature causes greater pressure inside the evaporator, which means higher draw on your compressor.
Your condensing fan motor might also be going bad if you're noticing an unusually high amperage draw, as this is one of its functions. In addition to causing an increase in your electric bill, a faulty fan can cause damage to other parts of your unit by allowing too much heat into it.
If any component fails in your system (or if there's simply not enough refrigerant), then you may need to replace it with something new so that everything works properly again!
High head pressure is one of the causes for high amperage. The compressor may be working harder because of a dirty condenser coil, a bad capacitors (they can go bad over time), or even a faulty condensing fan motor.
You can be sure that the coil is dirty or blocked if the compressor starts to pull high amperes only after the air conditioner is shut off for a few hours. The condensing fan motor going bad will not cause this problem, but it may make your unit run louder than normal and overheat more easily. And while you're troubleshooting, check out whether your capacitor has gone bad; if so, it should be replaced by an electrician or HVAC technician as soon as possible because it can catch fire under certain conditions.
One of the most common reasons for high amperage draw is a low refrigerant charge. If you have to run your air conditioning system more often than normal, it's likely that you need to add refrigerant.
To check this, you'll need a set of gauges to measure pressure levels within an air conditioning system.
One common reason for high amperage is low refrigerant charge on the unit. Refrigerant is measured in pounds per square foot (psf), and this measurement should be checked every five years or so. If your system is low on refrigerant, it will pull more amps to compensate for it.
To check your system's refrigerant level, you'll need an electronic thermometer that measures liquid temperatures down to -22 degrees Celsius (-7 degrees Fahrenheit). Once you've got this tool, turn off all power to your HVAC equipment so that no one gets hurt while working with high voltage electrical lines. Then follow these steps:
If the refrigerant charge is low, the compressor must work harder to keep up with the cooling demands of your house, resulting in high amperage draw. This can be caused by a variety of factors including:
To check this, you'll need a set of gauges to measure pressure levels within an air conditioning system.
The gauge will tell you whether there's enough refrigerant in your system and that it's being properly charged by the compressor. When you're working with refrigerant, it's important to have the correct type of gauges for each job:
The compressor overload thermal protection device is a safety device that protects the compressor from overheating. It can be caused by:
Compressor overload thermal protection device is a safety device installed on compressor motors to keep them from overheating and burning out due to high electrical loads over extended periods of time. When the current is too high, this device cuts off the power to prevent damage.
If your compressor starts pulling a lot more amps than normal without any other obvious issues, chances are that it's just protecting itself from overheating. Compressors can overheat in the following ways:
