Air Conditioner Capacitor-All Types , Replacement, Capacitor Cost

A capacitor is a tiny cylindrical structure that supplies and stores electrical energy inside your Air Conditioner Capacitor. The capacitor’s function is to give a high-voltage jolt (around 400 to 600 volts) to the compressor, fan motor, and blower motor while your air conditioner is turned on and we learn how to do Air conditioner capacitor replacement And i mentioned the air conditioner capacitor cost .

Your air conditioner will start blowing cool air in your home after the capacitor jumpstarts those components. The capacitor, analogous to a rechargeable battery, absorbs and saves electricity while the air conditioner is working. The capacitor produces a fresh burst of energy each time the air conditioner turns on. You could have different capacitors depending on the air conditioning unit.

Air Conditioner Capacitors All Types

An ac capacitor is the most common component to malfunction in any air conditioner, regardless of type. Worst of all, most capacitors malfunction during the hottest or coldest months of the year, and the cause isn’t purely coincidental.

Most air conditioners and heat pumps have two kinds of capacitors: a run capacitor and a start capacitor. They both have different functions in the air conditioner. Some air conditioners have one, and others have both, and some also mix the two.

  • Start Capacitor: This component provides an initial burst of electricity to start the compressor or fan motor. The start capacitor is no longer needed until the motor has started spinning or cycling.
  • run capacitor: The run capacitor takes over after the compressor and fan blade are turned on. The aim of the run capacitor is to provide additional power for long periods of time.

There are six(6) Simple Steps To Replace Air conditioner capacitor replacement

Replacing a capacitor is easy and requires only a few equipment and components, the majority of which you might already have. However, keep in mind that capacitors are intended to hold electrical current, so touching one or attempting to isolate it without first discharging the current it is carrying will result in a shock. To discharge, simply slide the blade of a screwdriver over the two metal contacts. You risk getting a bad shock if you don’t do this.

  • Step 1: Turn OFF the Power

    Switch off the air conditioner’s control. A block fuse or a local circuit breaker is usually placed in a box near the outside air conditioner unit; to turn off the battery, take out the block fuse or turn off the circuit breaker.

    If there is no outside shut-off box, switching off the electricity at the main service panel by turning off the circuit breaker that controls the air conditioner. This would be a 240-volt double-bar breaker with the air conditioner breaker written on it. Also, switch your home’s thermostat to the “down” spot. When you operate, this will prevent small bursts of low-voltage current from reaching the capacitor.

  • Step 2: Remove the Access Panel

    Remove the locking screws from your air conditioner unit’s access panel with a nut driver. This panel is usually found on the upper corner of the air conditioner’s casing. Keep the cover and screws in a secure place.

  • Step 3: Buy a New Capacitor

    Within the panel, look for the capacitor. It’s usually in the form of a can, with a tag on one side. Take note of the technical data on the sticker, such as the load voltage, capacitance, and tolerance.

    Replace the capacitor for one that meets the same standards. The new capacitor may have a slightly different design from the old one, but that isn’t a concern as long as it can be installed in the same room.

  • Step 4: Discharge the Capacitor and Label the Wires

    The capacitor can be retaining stored energy even though the power is switched off, and this current must be discharged before you can operate on it safely.

    Hold the blade of an insulated screwdriver over the two metal terminals that reach away from the capacitor body to discharge the capacitor. This essentially “short circuits” the capacitor, releasing any remaining electricity.

    Examine the old resistor now and make a note of where the three wires fan, normal, and compressr are connected. The old capacitor’s top should have labels indicating where each wire should go: Fan for fan, C for normal, and “Herm” for compressor. Mark each wire with a marker and small tabs of tape to indicate which terminal it was connected to. It’s now possible to remove the old capacitor’s spade wire connectors and wires. Remove the capacitor from the unit by unscrewing the mounting strap and dragging it back.

  • Step 5: Install a New Capacitor

    Place the new capacitor in the same location as the old. To lock it in place, use a mounting strap either the old one or a new one if necessary. Make sure the connections are right by sliding the spade wire connectors’ ends onto the required posts on the new capacitor: fan wire to Fan post; typical wire to C post; compressor wire to Her post.

  • Step 6: Turn Power ON and Test

    Switch on the circuit breaker or reinsert the block fuse at the power box to switch on the air conditioner unit.

    Return the thermostat to the ON spot, then lower the temperature to allow the air conditioner to turn on. If it doesn’t work, the most possible reason is because the capacitor’s wire leads have been connected improperly.

    Turn off the battery, discharge the capacitor, and double-check the wire connections. Replace the access cover until you’ve checked that the device is running properly.

air conditioner capacitor cost

Air Conditioner Capacitor Cost The price of replacing an air conditioner capacitor varies depending on the manufacturer and features. Replacement costs, on average, vary from $120 to $150. Branded units can be much more expensive than generic units, with some going for as much as $400.

Note that these rates include the expense of skilled labour to replace the component, but if you have the skills to properly and accurately mount the capacitor yourself, you can save money.
