What is a Sharp Error Code E8?
Error Code E8 on your Sharp air conditioner typically indicates an issue with the unit’s protection system, which can be triggered by a variety of factors such as a malfunction in the fan motor, issues with the control board, or problems related to the air flow. This error code suggests that the air conditioner has detected a condition that could potentially cause damage to the system, prompting it to enter a protective mode to prevent further issues.
Recommended solution/fix steps
To fix the E8 error code on your Sharp air conditioner, you can follow these simple steps:
- Power Off: Start by turning off your air conditioner completely. This can be done either using the remote control or by switching off the power at the circuit breaker.
- Check Filters: Open the front panel and check if the air filters are dirty. If they are, clean them with mild soap and water, then let them dry completely before reinstalling.
- Inspect Vents and Coils: Make sure that the air intake and output vents are not blocked. Also, check the coils for any visible signs of dirt or damage. Clean gently if needed.
- Reset: After checking and cleaning, reset the air conditioner. This can usually be done by turning the power back on. Some models may have a reset button, which should be pressed if available.
- Power On: Turn your air conditioner back on and set it to your desired settings. Observe if the E8 error reappears.
- Professional Help: If the error persists after these steps, it’s best to call a professional technician. There might be more complex issues like motor dysfunction or control board problems that require specialized skills and tools to fix.
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:
- Turn off the air conditioning unit on your thermostat
- Power off your air conditioning unit
- Locate the reset button
- Press the reset button for 5 seconds
- Turn your air conditioning on using the thermostat
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.
