    Michael Miller,
    An EC error code on a Senville mini split will happen when the unit sees or senses a refrigerant leak.
    This can be from a faulty temperature sensor, leakage or blockage in the lines, or a malfunctioning indoor main board.

    Senville mini split was showing P4 in the winter and not making heat. And now it the summer it says code EC? Any ideas ?

    Senville heat pump Mod.# SENL09CD/IZ indoor unit with Mod # SENL09CD/OZ outdoor unit. 115 volt.
    When call for cooling is made the outdoor unit dose not operate ( no condenser fan motor or compressor is operational.
    And at the same time the indoor blower operates at a very low speed regardless to remote control selection and no indication error code light is illuminated.

    Senville 24CD AC unit, new install, set it on 72 degrees its 68 degrees in our home and still running set on cool.

  5. Were you able to resolve your P6 code? We are getting the same and not certain what went wrong – bought precharged 28,000 BTU tri-zone Senville Aura with 25 ft linesets, followed installation instructions, tested pressure and vacuumed lines. Units ran for 30 mins before throwing a P1 code, turned off and back on; ran for 1 hr before throwing a P6 code. Now, every time the units are turned on all indoor units throw a P6 after approximately 3 minutes. Tech will be coming back tomorrow to check it out, but I’m wondering if there’s something simple we overlooked.

  6. Just install new Senville dual zone mini split vacuumed lines, opened valves after powering on immediately receive P6 code on both heads, double checked for leaks, all good there. Powered off at the breaker for 15 min still getting P6 code. Contacted heating/ac company say not enough refrigerant according to e code on compressor

    Purchased and had my Senville SENL/09CD/220/1X install in Aug 2020. No issues until about 1 month ago. I received a P4 code. Came on went off. Just happened this morning (12/22/2020), came on went off. Heats/Cools fine. Please advise.

  8. Most often the issues are from poor installation practices. It pays to hire a professional. In many cases extra refrigerant is required to compensate for additional length of the refrigerant lines. This needs to be done in the field properly and weighed in. I have installed multiple systems and no issues yet. My customers have been more than satisfied. Great equipment at a great price!

  9. I had the Senville 36k BTU compressor with 4 – 9k BTU wall units installed around 14 months ago. Everything has worked great until today. Two of the wall units (farthest from the compressor) turn On for around 5 seconds, the display shows temperature, then the unit shuts Off. The display then shows 2 dashes (- -). I looked through the manual and it says nothing about the dashes. HELP !

  10. I’m having the same issue. Just installed a SENA-30HF/D 28,000 BTU dual zone unit and I’m getting a P6 code as well. I confirmed no leaks prior to releasing coolant so don’t believe leaks are the issue.

    The unit turned on for a bit yesterday but I noticed frosted lines by the low pressure valve so I shut it off. Tried testing it today and that’s when I got the P6 code. I also tried testing the pressure in the lines today and I don’t seem to be getting any pressure at all.

    Wondering why the unit would need additional coolant if it’s supposed to come pre-charged.

    Any help would be appreciated.

    Raul Gutierrez,
    Senville 4 zone 36000 btu – error code P6
    P6 error code on Senville AC means the outside unit is not cooling and needs more refrigerant.
    Possibly one of the valves is not open all the way and not sending refrigerant to the whole unit.
    It’s most common when it’s super hot outside and the unit isn’t able to cool properly.
    -RR

  12. I just installed a Senville 4 zone 36000 btu and did not work.
    It gives me an error code P6, what can I do to fix it.
