It does not require a start capacitor in order to function.

The unit with this capacitor subtype uses both a start capacitor and a run capacitor. The start capacitor gives the initial push for the motor, disengaging once the fan is in motion. The run capacitor keeps the fan going and powers the compressor. If you were to have a run capacitor and a start capacitor in front of you for a side-by-side comparison, you would notice that both a single run capacitor and a start capacitor have two terminals on top, while a dual run capacitor has three.

The F terminal powers the condenser fan motor, and the H terminal powers the compressor. Important note: the colors for each wire can be different from one AC appliance to another, but the placement of each wire will never change. While it can be difficult to determine if the AC capacitor is bad , there are signs that point to it:. The outside AC fan stops working. When this happens, your air handler will spew hot air in place of cold air.

You may even find a start delay with the air handler. The capacitor is expanding or bulging on top. This can sometimes look like a dome or even a mushroom top. The compressor stops working. This problem only occurs with dual run capacitors. If you find yourself dealing with issues 1 or 2 above, you should know that you may not be dealing with a bad capacitor. Warning: Avoid using your fingers or conductive materials, such as metal, for this.

Otherwise, you may be electrocuted, which will lead to serious injuries or fatality. Single Run Capacitors: If the fan starts spinning on its own and your unit has a single run capacitor, then the capacitor is likely weak and near its way out.

If the fan does not spin, the capacitor has likely failed, which could also mean damage to the fan motor. Dual Run Capacitors: On the other hand, if the fan starts spinning and your unit uses a dual run capacitor, this could mean one of three possibilities:.

Finally, if the fan does not spin and your unit has a dual run capacitor, then the run capacitor will need to be replaced. Here are step by step run capacitor replacement instructions. Read them over, and if you have the tools and basic skills to test the capacitor, go for it.

How to replace AC capacitor is pretty straightforward but with a few precautions. Residential central AC units or heat pumps can require round or oval-shaped capacitors, which both vary in length.

Before purchasing a new capacitor, what is the shape of your current one? While you can switch a round capacitor for an oval capacitor or vice-versa, it is best to stick with what you already have.

The ones you should especially know:. Whenever you come across this situation, note that the small value is related to the fan motor. Mismatching capacitors by capacitance will likely damage your AC appliance. An undersized capacitor, for instance, will overheat the fan motor and compressor by forcing them to work harder, while an oversized capacitor will overcharge them. Tolerance: The tolerance rating is represented by a percentage. Voltage: The voltage rating is how many volts V can pass through the capacitor.

Newer condenser units commonly require capacitors with VAC. Luckily, the answer is, No. Unfortunately, Goodman does not sell start capacitors. Many ACs can be fitted with capacitors from other manufacturers as long as the part has the right specifications as the old capacitor.

The large discrepancy between the numbers is based on a few factors:. Keep in mind that while replacing a bad capacitor can be DIY, it is not a task for the inexperienced.

Not only can the job lead to serious, if not fatal, electrical injuries, but a non-professional might not be able to detect if the unit is experiencing other issues such as a damaged fan motor or compressor.

For these reasons, we suggest calling a reliable HVAC professional to do the job for you. These prices include the cost for the capacitor and an hour or less of labor.

A weak capacitor may do its job for the most part, but by leaving it in, you will be forcing the fan motor to put in more effort to compensate for the capacitor. This will eventually overwork the motor, causing it to fail.

No, all capacitors go out eventually. But keep in mind they are fairly inexpensive, and experienced DIYers can make the repair. This said, you can ensure your capacitor s has a longer lifespan by regularly cleaning the condenser unit. In other words, you can. Do I always have to disconnect the run capacitor when I want to test it with a multimeter?

However, for homeowners who perform regular maintenance checks on their units, constantly removing the capacitor can get annoying. You can test your run capacitor under load which is to say, when the AC unit or heat pump is on by using a clamp multimeter. Using a non-clamp multimeter can lead to serious, if not fatal, injuries. Voltage Rating. There are various types of capacitors for different AC models, and they all have individual voltage ratings.

The higher voltage a capacitor is, the more expensive the part, so it may be tempting to purchase a lower level capacitor for replacement. However, this puts a much more significant strain on the capacitor, shortening its lifespan. Again, most capacitors have a lifetime of about twenty years, but that also means they have limited use. There are several guides on how to swap out a capacitor by yourself, but here are some of the basics to keep in mind: Find the right replacement capacitor.

The capacitor should have a voltage and capacitance level on it, and you need to match that in your replacement. Writing down that and the make and model of your air conditioner can help in finding the type of capacitor you need. Power down your air conditioner before starting any fixes. Working with high-electricity machinery can be dangerous without proper safety. Discharge the capacitor.

You need to discharge that energy so as not to cause damage to yourself during handling or after disposal.
