Lloyd – Error Code P3

Lloyd – Error Code P3

Is your Lloyd air conditioner showing up with Error Code P3 on the screen?

What is a Lloyd Error Code P3?

The Error Code P3 on your Lloyd air conditioner indicates a problem related to the refrigerant gas in the system. This could mean that there is not enough refrigerant gas, which is essential for cooling, or there might be an issue with the air conditioner’s control board (PCB) incorrectly reading the gas pressure. This error affects the cooling efficiency of the air conditioner and needs to be addressed to ensure it operates correctly.

Recommended solution/fix steps

To fix the Error Code P3 on your Lloyd air conditioner, follow these steps:

1. Turn off the air conditioner: Always start by turning off the unit to ensure safety before performing any checks or repairs.
2. Check for visible leaks: Inspect the outdoor unit and connecting pipes for any signs of refrigerant leakage, such as oil stains or hissing sounds.
3. Contact a professional: Since dealing with refrigerant gas and electrical components requires specialized knowledge and tools, it’s best to call a qualified HVAC technician to diagnose and fix the issue.
4. Refrigerant refill: If the technician finds that the refrigerant is low, they will need to refill it to the correct level. They’ll also check for leaks and repair them to prevent the issue from recurring.
5. PCB check: If the refrigerant level is fine, the technician will examine the air conditioner’s control board to ensure it’s functioning correctly and not misreading the gas pressure. They may repair or replace the PCB if necessary.

It’s crucial to address the P3 error promptly to prevent further damage to your air conditioner and to maintain its efficiency and cooling performance.

Troubleshooting to try

• Check for a dirty air filter
• Check your thermostat settings
• Check your air conditioner circuit breakers
• Check your outdoor unit
• Check all air vents

How to restart/reset/reboot your Lloyd air conditioner?

You may find your Lloyd air conditioning unit needs resetting if it starts to malfunction or isn’t responding to any input via your control panel or remote control. Resetting your air conditioner re-starts the internal computer and can often restore the unit to normal working order. The exact instructions will vary depending on your model of Lloyd air conditioner.

Typically, this procedure will be:

1. Turn off the air conditioning unit on your thermostat
2. Power off your air conditioning unit
3. Locate the reset button
4. Press the reset button for 5 seconds
5. Turn your air conditioning on using the thermostat

Lloyd Maintenance

During normal air conditioner operation, dust, dirt, moisture from humidity or condensation, and microbial growths can build up on internal components. Left unchecked, these issues can corrode components like the evaporator coil and condenser coil. Over time, those components can become less effective and lead to a loss of efficiency or worse, a shorter air conditioner lifespan.

Regular AC maintenance and tune-ups can minimize many of the issues caused by a build-up of dirt and debris. If they are performed by an HVAC technician, these inspections allow your contractor to check for longer-term issues and in some cases take proactive steps to prevent premature failure or inconvenient breakdowns during the cooling season.

Annual air conditioner preventative maintenance may also be a requirement to keep your warranty valid as well. Many manufacturers state on warranty documentation that installation and maintenance by a licensed HVAC service provider are a part of the warranty conditions.

Cleaning your Lloyd Air Conditioner

One simple way to potentially save money and prolong the life of an AC system is to make sure the outdoor unit stays clean. During normal operation, a fan in the outdoor unit pulls air through the condenser coil. Airborne dust and dirt particles and debris from nearby foliage can get lodged in the coil fins, restricting airflow and affecting performance.

Change or clean the air filters

The most important maintenance task that will improve the efficiency of your air conditioner is to routinely replace or clean the air filters. Replace one-inch pleated filters once a month. If you’re unsure of the type of filter to use, your Lloyd Dealer can recommend one based on your specific system. For all other filter sizes, your Lloyd Dealer will check, clean, or replace them at your annual maintenance visit. Remember, filters may need more frequent attention if your air conditioner is in constant use, is subject to dusty conditions, or you have pets in the house.

Clean the external unit

• Turn off the power
• Remove the top panel and remove any large debris you find in the case
• Use a vacuum cleaner with a soft bristle nozzle to remove dust from hard-to-reach places. Be careful not to damage parts – many components can bend easily
• Unscrew the grille on top of the Lloyd air conditioner. The fan usually rises with the grille, so be careful not to damage the electrical connections
• Wipe the fan with a clean, damp cloth
• Clean the condenser – it has a smooth, flat surface, so the process will not take long and will not be complicated
• Assemble the unit. Return the fan and grille to their original position and screw them back onto the unit
• Leave the unit off for 12 to 24 hours

Remove debris from the unit

Over time, things like leaves, dirt and grass clippings will build up on the outside of your air conditioner, decreasing system capacity and reducing airflow. You should trim any shrubs or other plants back from around the air conditioner to keep from impeding airflow to and from the unit.
