Sharp AC – Error Code H5

Sharp – Error Code H5

Is your Sharp air conditioner showing up with Error Code H5 on the screen?

What is a Sharp Error Code H5?

The Error Code H5 on your Sharp air conditioner indicates an “IPM Protection Error.” This usually means there is a problem with the Inverter Power Module (IPM) in the air conditioner. The IPM is responsible for regulating the power supply to the air conditioner’s compressor, ensuring efficient energy use and operation. When this error occurs, it suggests that the IPM is not functioning correctly, potentially due to overcurrent, voltage irregularities, or a malfunction in the compressor.

Recommended solution/fix steps

1. Power Off: Start by turning off your air conditioner completely. This is important for safety and to reset the system.
2. Unplug and Wait: Unplug the air conditioner from the power outlet and wait for about 15-20 minutes. This waiting period allows the system to reset and can sometimes clear minor glitches.
3. Check for Obstructions: While the system is off, check for any obstructions or debris around the outdoor unit, especially near the fan and vents. Clean any dirt or leaves that may be blocking the airflow.
4. Reconnect Power: After the waiting period, plug the air conditioner back in and turn it on.
5. Observe: Pay attention to whether the error code reappears. If it does, this indicates a more serious issue.
6. Professional Help: If the error persists, it’s time to call a professional technician. They can diagnose and repair issues related to the IPM or the compressor that are not fixable through simple troubleshooting.

Remember, if you’re uncomfortable performing any of these steps or if the problem seems complex, it’s always best to contact a professional for assistance.

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 Sharp air conditioner?

You may find your Sharp 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 Sharp 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

Sharp 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 Sharp 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 Sharp Dealer can recommend one based on your specific system. For all other filter sizes, your Sharp 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 Sharp 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.
