        I had the same problem. I found a relay that carrier used for my mini split system is made in China. It’s a very cheap relay. It activates the condenser and with the usage it would get stuck and it will not open when satisfy and it will keep the compressor running until it builds pressure and it causes an error on the board. I replaced the relay with the exact same one. I found it on the internet it came from China and so far it’s been working fine. If it goes bad again i will replace it with a heavier duty relay.

    Hi this is to inform you that my carrier split inverter made showing error P1 whenever I try to switched on th AC.i don’t knw what had happened can u please suggest me what to do and what does it mean.

  25. Nitesh P. Yelve says:

    CL message seen in the Carrier ACs, is a call for cleaning the AC filters. Switch off the AC. Open the front panel of the AC and take out the filters. Clean them using either vacuum cleaner or simply wash them under running water. Dry them properly if you have washed them. Switch on the AC and press ‘LED Display’ button on the remote control four times. Switch off the AC and again switch on. You won’t see the CL message.

      It is just a reminder that the AC has run for 240 hours of operation and time to clear the air filters. Turn off AC, clear the filters and turn on the AC. And when the code CL comes, press the LED button on your remote 4 times, the counter gets reset and the message should disappear. You would see that message again after 240 hours of operation.
