What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

Common Problems with the Sanyo Air Conditioner

#1 Air Conditioner Has Stopped Working

If your AC unit is powered on, but has suddenly stopped working, then your unit may have an overload current detected. This happens when the cooling system works overtime, and uses excess energy to perform the cooling operation for your room. Your air conditioner stopped working as an overheating fail-safe that protects your unit from damage due to overloading.

As long as there is no burning or smoke smell, there is no cause for alarm. Simply wait for your unit to cool off, then inspect for any signs of a clogged air filter, refrigerant leaks, or worn capacitor. Troubleshoot according to the root cause of the problem.

#2 Air Conditioner Won't Power On

If your AC unit won't turn on at all, check first if you have a power failure within your home. See if other devices are functioning just fine, or if they also won't power on. Check the availability of your power supply, and look for a tripped circuit breaker connected to your unit. Flip the switch back into its original position to reset the connection.

If your circuit breaker trips often due to your air conditioner, unplug other devices from the same circuit, and observe if the problem goes away. Otherwise, you may need to check for an active circuit failure, or contact an electrician to check the cause of the circuit failure for you.

Another reason for this Sanyo air conditioner error is a broken capacitor and compressor. The compressor runs the entire HVAC system, which is why when this component breaks down, it can mean the end for your AC unit. Similarly, the capacitor is responsible for the flow of electricity around your unit. Have technicians inspect your unit for replacements.

#3 Air Conditioner is Flashing Error Codes

An air conditioner detecting error signal issues with your unit will flash error codes to alert you of potential problems within your air conditioner. These error codes indicate the problems with your unit, including the indoor discharge air temp sensor, air discharge port, system controller, and other components within your AC unit.

Cross-reference the error codes with your user's manual to troubleshoot your unit. If this does not work, we suggest you to contact a professional for repairs and replacements.

How to Reset Your Sanyo Air Conditioner

Reset Point: Power Cord/Reset Button

To reset your Sanyo air conditioner, turn your unit off first. Unplug the power cord from its socket, and wait for 30 seconds before plugging the power cord back into the electrical outlet. Power your unit back on, and see if this resolves your aircon issues.

Select models may have a reset button on their remote control unit. You may need a pin to be able to press and hold the reset button on the remote controller. Press and hold the reset button for 3-5 seconds until the unit powers off, then wait for the unit to restart, and see if this solution fixes your air conditioner.

Sanyo Air Conditioners Troubleshooting Guide

#1 Check the Error Signal

The first step in troubleshooting your Sanyo air conditioner is to check the error code flashing on the screen. This code will indicate the underlying problem detected within your unit so you can figure out how to troubleshoot the root cause of the aircon issue. The error signal will also indicate where the issue lies: either with the indoor unit or outdoor unit.

Cross-check the error code with your user's manual, and follow the troubleshooting steps that follow. More often than not, your air conditioner manual will have step-by-step solutions in troubleshooting common problems with your unit.

Make sure you have the correct user's manual with you for your specific Sanyo air conditioner. The error codes of one model or aircon type may be different from the rest, and the troubleshooting steps may differ as well. Always use the manual written for your unit model.

#2 Vacuum Your Air Filter and Coils

No time to wash your filters clean? Vacuum up the dust and debris instead. Use your vacuum cleaner with a nozzle or brush attachment to gently remove excess dirt from your air filter, evaporator coil, condenser coil, and other components in your cooling system. This will help reduce the amount of dust blocking the airflow in your unit, and clear the system of dirt.

Use a can of compressed air as well to dislodge any stuck-on grime from your AC unit without damaging any parts or components. Cleaning your AC unit this way is not a deep cleaning solution, but is a quick fix to get your Sanyo air conditioner up and running again.

#3 Call the Pros

Most aircon issues with your Sanyo unit will have quick fixes you can do at home, but without tackling the cause of the aircon issues, these problems will pop up again and again, wearing down your air conditioner. Avoid costly repairs from late-stage, damaged units, and have aircon technicians inspect your air conditioners to fix up any weak points beforehand. Contact us for a free consultation!
