Understanding the Fujitsu Operation and Timer Light
Before we dive into the reasons why the Fujitsu operation and timer light might be flashing 5 times, let’s first understand what these lights are and what they indicate.
The operation light on a Fujitsu air conditioning unit indicates that the unit is on and actively cooling or heating the room. On the other hand, the timer light indicates that the unit’s timer function is in use.
When these lights flash simultaneously, it usually indicates that there is a problem with the unit that needs to be addressed. The number of times the lights flash can indicate the specific issue. In the case of the operation and timer light flashing 5 times, it indicates that there is a problem with the unit’s outdoor unit.
Now that we understand what the operation and timer lights are and what they indicate let’s explore the possible causes of them flashing 5 times.
Possible Causes
There are several reasons why the Fujitsu operation and timer light might be flashing 5 times. Some of the most typical reasons are as follows:
Low refrigerant levels:
If the refrigerant levels in your Fujitsu air conditioning unit are low, it can cause the outdoor unit to malfunction, which may result in the operation and timer light flashing 5 times.
Faulty outdoor unit fan motor:
The outdoor unit fan motor is responsible for circulating air over the outdoor unit’s heat exchanger. If this motor is faulty or not working correctly, it can cause the operation and timer light to flash 5 times.
Malfunctioning compressor:
The compressor is responsible for compressing the refrigerant in the air conditioning unit. If the compressor is malfunctioning or not working correctly, it can cause the operation and timer light to flash 5 times.
Dirty air filters:
Dirty air filters can cause the air conditioning unit to overheat, which can lead to the operation and timer light flashing 5 times.
Clogged drain line:
The drain line is responsible for removing the condensation that is generated by the air conditioning unit. If the drain line is clogged, it can cause the outdoor unit to malfunction, resulting in the operation and timer light flashing 5 times.
These are just some of the possible causes of the Fujitsu operation and timer light flashing 5 times. It’s essential to troubleshoot the issue to identify the root cause before attempting any repairs.
