A failing compressor will result in inefficiencies with the HVAC unit. It can be difficult to diagnose such a problem if you’re not from an electrical background. That is why you should be looking for air conditioning Perth contractors if you suspect the problem is with the compressor. If you feel you can do it, then read on because this guide will come in handy.
How and Air Conditioner Compressor Works
The air compressor has a motor that is meant to start and run windings in the HVAC unit. The motor functions by turning the piston which will then compress the refrigerant that is found in the unit. The motor needs to be operational at full speed for the system to be up and running. Your air conditioner will have few problems functioning if the compressor is not working correctly.
Fixing the Air Compressor
If you’re thinking about fixing the compressor on your own, the first thing you will need to do is to turn off system off. You don’t want to be a victim of electrocution before even starting the work. The first thing you’d want to do after switching the unit off is to locate the circuit breaker. You can find it the main electrical panel in the unit. The circuit breaker you will be looking for will be labeled “AC” or in some instances “Heat Pump.” The AC should be safe to work on once you’ve flipped the circuit breaker.
It is important that you have the right screwdriver for the job. Next, locate the compressor cover and remove it. You will find it mounted on the side of the condenser unit. If there is a fan, you will need to carefully unscrew it before you can access the compressor. The fan is likely to have long wires and you will need to be extra careful when detaching it.
Inspecting the Compressor
The compressor looks like an oval-shaped cylinder and has wires exiting from the unit. There is a chance that the lid could be leaking or swelling. It will need to be replaced with the exact same part. If you’re replacing the capacitor, it must have the exact voltage.
Removing the Wires
The wires should be carefully removed from the terminals on top of the capacitor. Instead of using a screwdriver, you should look for needle-nose pliers.
Checking the Capacitance
Make sure you’re changing the multimeter to capacitance settings. Check each terminal to ensure that reading is the capacitance ratings for the compressor. Ideally, the reading should be within 10% of the ratings. If it is not so, the capacitor unit will need to be replaced.
Inspecting Wire Connectors
The wire connectors will also need to be inspected for any signs of wear and tear. They might have also been burnt. Getting to do the repairs can be challenging especially if you have no understanding of electrical components.
