Issues with Fujitsu Heat Pump

Hi everyone!


My air conditioning has stopped working today. It's a Fujitsu Air Conditioner and it keeps flashing lights including a red timer light. According to other websites, I have turned off the isolation switch for five minutes which didn't help and I have been looking for a test button on my remote but I don't seem to have one.


Thank you in advance.

The flashing lights are an error code. You need to count the flashes and then search the Web for a list of error codes for your model.
