Any idea about random E1 codes? My indoor unit would randomly throw the code after about 10 to 12 minutes and stop but it seemed to be only when used for heat. Yesterday my HVAC guy discovered nearly every wire on the outdoor and indoor was loose. Once tightened we were outside with the unit running for at least 30 minutes while he checked refrigerant and other things (doing a checkup) and the unit didn't throw the code. 12 hours later I turned the unit off. This morning I turned it on and 10 minutes later the E1 code appeared again. Anything else I should steer him to when he comes back? Also, for diagnosing it, would it help if the unit had the E1 code already activated when he shows up or does it not matter? This is a Carrier mini split. Thanks
@@azjoe_6310 it could be damaged or loose wiring. Usually field installed wiring. Make sure there are no splices, the correct wire was used and that it isn’t running through any conduit
@@austindillon443 Thank you so much for the reply! I greatly appreciate you taking the time to respond. My tech is retuning in a few days to replace a board on my York package unit so I will follow up with this information. Have a great 2025!
@ of course and good luck with the York package unit. I used to work for a York distributor and remember lots of boards being replaced due to moisture being pulled into the control compartment because of the negative pressure created by the blower
