Unplug the equipment from the facility outlet or flip off the circuit breaker to make sure there isn’t a present flowing to the capacitor.
Step 3: Find the Capacitor
Find the capacitor on the equipment’s circuit board. Determine the 2 terminals and observe their polarity (if marked).
Step 4: Discharge the Capacitor
There are a number of strategies to discharge a capacitor. One frequent technique is the “resistor discharge technique.”
| Resistor Discharge Technique |
|---|
|
One other technique is the “short-circuit discharge technique.”
| Brief-Circuit Discharge Technique |
|---|
|
Observe: Watch out when utilizing the short-circuit discharge technique, as it might create a small spark.
Step 5: Double-Test the Discharge
Use a multimeter or voltage tester to make sure the capacitor has been totally discharged. Set the multimeter to measure voltage within the DC vary (sometimes 200V or larger). Join the probes to the capacitor terminals and observe the studying. If the voltage is lower than 1V, the capacitor is safely discharged.
Eradicating the Previous Capacitor
1. Flip off the facility to the unit.
Earlier than you start any work, it is very important flip off the facility to the air con unit. This may be executed by flipping the breaker that provides energy to the unit, or by turning off the principle electrical panel.
2. Take away the entry panel.
As soon as the facility is off, you’ll be able to take away the entry panel to the capacitor. This panel is usually positioned on the aspect or high of the unit.
3. Find the capacitor.
The capacitor is a cylindrical-shaped object with two terminals. It’s normally positioned close to the compressor.
4. Discharge the capacitor.
Earlier than you take away the capacitor, it is very important discharge it. This may be executed by utilizing a voltmeter to measure the voltage throughout the capacitor. If the voltage is above 50 volts, you’ll be able to discharge the capacitor by touching the terminals along with a screwdriver.
5. Disconnect the wires from the capacitor.
As soon as the capacitor is discharged, you’ll be able to disconnect the wires from the terminals. You’ll want to notice which wire goes to which terminal so that you could reconnect them accurately.
6. Take away the capacitor.
As soon as the wires are disconnected, you’ll be able to take away the capacitor from the unit. You’ll want to put on gloves when dealing with the capacitor, as it might be sharp.
Extra suggestions for eradicating the previous capacitor:
- If the capacitor is mounted on a bracket, chances are you’ll must take away the bracket earlier than you’ll be able to take away the capacitor.
- If the capacitor is troublesome to take away, you’ll be able to attempt utilizing a pair of pliers to softly pry it unfastened.
- Watch out to not harm the capacitor or the encircling elements when you’re eradicating it.
Putting in the New Capacitor
After getting eliminated the previous capacitor, it’s time to set up the brand new one. Listed here are the steps:
- Fastidiously deal with the brand new capacitor to keep away from damaging it.
- Orient the capacitor accurately in response to the markings on the unit.
- Gently insert the brand new capacitor into the slots or bracket the place the previous one was positioned.
- Safe the capacitor firmly utilizing the mounting screws or clips.
- Join the capacitor terminals to the corresponding wires on the unit. Make sure the wires are securely fixed.
- Double-check all connections to make sure they’re tight and correctly aligned.
- If needed, consult with the producer’s directions for particular capacitor mounting and wiring directions.
| Step | Description |
|---|---|
| 1 | Collect needed instruments and new capacitor |
| 2 | Flip off energy and discharge capacitor |
| 3 | Find and disconnect previous capacitor |
| 4 | Take away previous capacitor |
| 5 | Set up new capacitor |
| 6 | Activate energy and check |
| 7 | Consult with producer’s directions for particular capacitor mounting and wiring directions, if needed |
