There’s a significant probability something may be wrong with the air conditioner’s compressor if it can’t even turn on. This could appear to be terrible news, so it is. However, condensers can frequently be fixed. Before we leap to any assumptions, one should perform some diagnostics to identify the root of the issue. Bare in the heart that an average household can only go so far in this area. Several of the procedures that must be performed can be performed by experts only.
Given how frequently your ac unit operates, it’s not surprising if something must have gone awry with the motor. It does not imply that your air conditioning system is doomed. So don’t be alarmed. Your AC compressor isn’t functioning, but the blower is, so the situation isn’t too dire. We shall explain why this may be occurring through the means of this article.
What is an Air Conditioner Compressor?
A working compressor is required for an ac unit to function. A compressor is normally situated outside a basic household HVAC unit. The compressor’s primary purpose is compaction, as the title suggests. It operates inside an ac unit by condensing cool, reduced gaseous coolant until it becomes warmer and has reached a considerably greater pressure. The vapour coolant is then pressed into the compressor. Whenever the coolant is already in the condenser, the air conditioning process is said to be at its commencement. The procedure cannot begin if the Air conditioning compressor does not turn on.
Check the Power
If the compressor won’t bother to start, perhaps the basic thing to check is that the machine is receiving electricity. It’s always conceivable that a circuit has burned or a switch has bumped. If such problems occur frequently, you should get an expert to check on them. It is not typical for the circuits and switches to malfunction regularly. Constant starts and stops may damage the motor and the HVAC overall.
If the breakers and switches are in good working order, you might need to contact an air conditioning expert. The only alternative is if you possess recourse to and be able to use a voltmeter.
How to Troubleshoot
It’s important to recognize if an air conditioning issue stems from the compressor. That’s not fantastic news, but it offers HVAC technicians something to work with when they arrive. It’s reasonable to think that you’ll be out of options and may have to purchase a new device, but this isn’t always the case. Condensers have several components, any of which might malfunction and cause issues. The technician that comes to your house will examine and try to rule out the following possibilities:
Capacitors: Flawed or damaged capacitors are frequently the source of compressor difficulties. If the technician concludes that the capacitor would be at fault, he may replace it with a solid capacitor, which could permanently remedy the problem. Because the only option to diagnose a capacitor is really to replace it and check the device, that’s what is usually done whenever an AC condenser won’t turn up.
Start Relays: Similar to the capacitor, the HVAC expert may attempt changing a start relay, and that’s the only definite method to tell if it isn’t really operating properly. If the condensers operate after installing the new starting relay, the issue must be rectified and you’ll be good to go.
Valves – A faulty valve may cause serious issues in one compressor. The most prevalent problem is that if the coolant reaches the compressor input, it is fluid rather than gas. Under such conditions, the condenser may continue to function, but the ac unit will not chill the air. Luckily, changing the faulty valve generally fixes the issue.
Terminal Connections: The technician will also inspect the wire interconnections to verify everything is snug and secure. A faulty connection might lead to serious complications. If your motor only works occasionally, it might be as easy as this. There is always the possibility that the port connectors are just filthy. Clean-up may be sufficient.
Dirty Filters and Coils: The accumulation of waste and dust in the filtration, cooling systems, or compressor soil might cause the overall system to close down. A blocked air filter greatly lowers airflow, causing the heat exchanger to stop working. Blocked-up filters and cooling coil exert strain on the cooling system, causing it to heat. As in the best scenario, the compressor shuts down automatically before it is harmed. However, constant heating may need the replacement of the condenser. Clean the evaporator coil, change the air screens, and remove any clogs or blockages in the supplying vents to allow air to circulate freely.
What to Do with a Dead Compressor?
If your air conditioner’s compressor is determined to be fully dead, then you will most likely have two alternatives. Replace the faulty compressor or change the complete ac unit. The cost of replacing the condenser is an essential factor. If this costs less than half the price of a brand-new one, it’s usually the best option. However, if somehow the cost exceeds that, purchasing a new air conditioning unit is generally the most sensible option.
The Bottom Line
Routine servicing of the equipment is the crucial prevention approach since it eliminates the majority of problems before they become more serious. The air conditioner compressor is made up of numerous readily replaceable parts. With frequent inspections, the defective part is accurately identified and replaced, essentially eliminating the possibility of an Air conditioner compressor malfunction.
Unfortunately, even the greatest HVAC systems also have a limited lifespan. When your air conditioning system is more than 10 years old, might have hit the end of its lifespan.
System components eventually degrade as a result of persistent stress and strain. As you can expect, upgrading your complete system is not cheap. Nonetheless, it will operate much more effectively, and you will save month-to-month electricity bills.
An HVAC compressor that isn’t operating might be a source of stress and pain. If you spot a concern with the device, the best course of action is to contact an Air Conditioning professional.
FAQ – Why is my Air Conditioner Compressor not Turning on?
How do I know if my AC compressor clutch is bad?
It’s possible to check the AC compressor clutch with a multimeter. The compressor, usually located inside your car engine, will include a circular disc that spins when it needs to produce cool air or heat. When you turn on your AC, this disk also starts spinning and begins cooling the refrigerant gas. A faulty AC compressor may drop below its required pressure levels and won’t normally spin since it can’t produce cold air or heat. Your air conditioning system could still function but the HVAC compressor doesn’t activate without any problems.
How do I manually engage my AC compressor clutch?
There are a few ways to engage your AC compressor clutch manually. One way is to disconnect the negative battery cable for a few minutes and then reconnect it. Another way is to remove the relay located in the engine compartment and jump the two terminals together with a screwdriver. Make sure that when you’re done, you put everything back the way it was before so that the car will still start next time you turn the ignition switch on.
Be mindful that if either of these methods doesn’t work, then there’s something wrong with your AC compressor clutch, and you’ll need to take it to a mechanic to get fixed.
Is there a reset button on AC compressor?
There is no reset button on AC compressor. If the AC compressor clutch is not engaging, it may be an electrical issue and need to be diagnosed by a professional.
Why Is the AC Compressor Not Working Although the Condenser Fan Is Running?
The condenser fan may be running, but it won’t be cooling anything if the compressor can’t get started. One of the most typical problems with an air conditioner is the relay switch that changes from „off“ to „on.“
