Been working great since 2008, started blowing warm air , went outside and fan was running
Attached gauges and it’s like compressor not running but contactor pulled in and pressure was
Like it’s not running. Same if I put it in heat pump mode. The gauges read just like the unit was off. I’m pretty good on these units but this one has me puzzled, tcon 800 stat shows no codes
Strange when I turn the unit on y1 And y2 lights both come on but only y2 contactor pulled in
And the lights are flashing off and on
