20 Most Recent Fujitsu 36CS Air Conditioner Questions & Answers

To work out what the error code is press the orange start/stop button on the remote controller so unit operation is stopped.
Then press and hold "energy save" and "zone control" button simultaneously for at least five seconds, the error code will be along the lines of En:nn where the "En:" is the error code and the ":nn" indicates the indopor unit address if there are multiple indoor units connected to the one controller. If the upper vertical bar on the capital E is missing so it looks maybe like a 2 or something don't worry for some reasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check if there is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsating between terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC it will cause this error, the problem is normally dry capacitors in the 12 VDC power supply section. This model has two power supply sections on indoor pcb.
E1 Communication error between indoor unit and outdoor unit,
EF Discharge temperature abnormal

Try resetting the unit itself by shutting the breaker off then turn it back on and see what happen

I ran into that same issue with a Daiken. I ended up changing the board and the o.d. motor. The motor had damaged the board. Tech support had me change the board first. Second board was also damaged by the faulty motor. Changed the board and the motor, now its working well. If you are unsure find someone who has experience with that style unit and have the Tech Support # on hand for them.
