8 Common Fujitsu Halcyon Problems for Troubleshooting<\/h2>\n\n\n\n

Below are Fujitsu Halcyon air conditioner troubleshooting<\/strong><\/a> guides for eight common Fujitsu AC issues:<\/p>\n\n\n\n

1. Fujitsu Halcyon Air Conditioner Not Working Immediately After Power Interruption<\/h3>\n\n\n\n

Something doesn’t have to be wrong to explain why your Fujitsu air conditioner won’t kick in as soon as there’s a power interruption. Often, the unit goes on an Auto Restart mode where the compressor takes about 3 minutes before running. <\/p>\n\n\n\n

The Auto Restart mode generally protects the AC from potential damage. <\/p>\n\n\n\n

Fix <\/strong><\/p>\n\n\n\n

Wait for the AC to Auto Restart. The automatic process takes about 3 minutes. If the AC doesn’t restart, you can call an expert. <\/p>\n\n\n\n

2. Air Conditioner Won’t Start\/Turn On<\/h3>\n\n\n\n

Sometimes the Fujitsu Halcyon won’t power on, and there are three likely causes: a non-responsive remote control, power interruption, or faulty timer. <\/p>\n\n\n\n

Let’s discuss the trio:<\/p>\n\n\n\n

a) Non-responsive Remote Control<\/h4>\n\n\n\n

If the unit doesn’t turn on when you press the remote control, the remote control could be the problem. It could be that the batteries are exhausted or improperly installed.   <\/p>\n\n\n\n

It could also be that you are operating the remote at a distance of more than 20 feet or something such as a wall blocking the signal. So, you’ve to consider all those possibilities.  <\/p>\n\n\n\n

Fix <\/strong><\/p>\n\n\n\n

Consider replacing the remote control’s batteries, especially if it has been a while. And while at it, ensure you install them correctly (don’t interchange their polarity).<\/p>\n\n\n\n

Also, move closer to the AC when operating the remote (keep the range under 20 feet).<\/p>\n\n\n\n

And more importantly, avoid any walls which could be obstructing the signals. If the remote control still doesn’t work, press the ‘reset button’ on the remote to reset it. <\/p>\n\n\n

b) Power Interruption <\/h4>\n\n\n\n

If there’s a power interruption before starting the air conditioner, it won’t turn on. In that case, consider these three issues:<\/p>\n\n\n\n
