Kelvinator – Error Code H3

Kelvinator – Error Code H3

Is your Kelvinator air conditioner showing up with Error Code H3 on the screen?

What is a Kelvinator Error Code H3?

The Error Code H3 on your Kelvinator air conditioner indicates that the compressor, which is the part of the unit responsible for moving the refrigerant and cooling the air, is working too hard and might be at risk of getting damaged. This can happen if the air conditioner is under too much strain, like trying to cool a very hot room quickly or if there’s something wrong inside the unit.

Recommended solution/fix steps

To fix this issue, you can follow these steps:

1. Turn off your air conditioner and unplug it from the power source to ensure safety.
2. Check the air filters and clean them if they are dirty, as clogged filters can restrict airflow and put extra strain on the compressor.
3. Make sure the outdoor unit is not blocked by leaves, debris, or anything else that could restrict airflow.
4. Let the air conditioner rest for a while before plugging it back in and turning it on.
5. If the error persists, it might be due to a more technical issue like a faulty compressor or problems with the refrigerant levels, which would require a professional technician to inspect and repair.

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 Kelvinator air conditioner?

You may find your Kelvinator 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 Kelvinator 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

Kelvinator 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 Kelvinator 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.

• Use a dry cloth to wipe the indoor unit and remote control.
• A cloth dampened with cold water may be used on the indoor unit if it is extremely dirty.
• The front panel of the indoor unit can be removed, cleaned with water then wiped with a dry cloth.
• Do not use scourers or steel wool to clean the unit as they may damage the unit.
• Do not use a chemically treated cloth or duster to clean the unit.
• Do not use benzine, thinners, polishing powder or similar solvents for cleaning. These may cause the plastic surface to crack or deform.
• Never use water over 40ºC to clean the front panel, it may cause deformation or discolouration.
• Supply power must be disconnected before cleaning the indoor unit.

Change or clean the air filters

1. Lift the front panel of the indoor unit until it stops with the full support of the bracket
2. Hold the dust filter handle and lift it up slightly to take it out of the filter holder
3. Pull the dust filter downwards out of the indoor unit
4. Clean the dust filter with a vacuum cleaner or water, then dry out of direct sunlight
5. The healthy air freshening filters (if applicable) like Active carbon filter / BIO filter / Vitamin C filter / Silver ion filter are fixed on the dust filter. Remove the healthy air filters from the support frame of the dust filter. Clean the healthy air filters at least every three (3) months and replace them every 6 months. Clean with a vacuum cleaner if possible.
6. Install the healthy air filters back in position
7. Install the upper portion of the dust filters back into the unit, taking care that the left and right edges line up correctly and placing dust filters into position

General Maintenance

If the air conditioner is not going to be used for a long period of time:

• Operate in fan only mode for 3~4 hours to allow the unit to completely dry out.
• Switch off the unit and pull the power plug.
• Remove the batteries from the remote controller.
• The outdoor unit requires periodic maintenance and dust filter cleaning. Do not attempt to do this yourself. Contact your dealer or service technician.
