THANKS. I thought that was a weird post. Your Rear Zone 2 is a Penguin lo profile. Penguins were susceptible to humidity causing corrosion on the Phone type connections at the Evaporater. Take the phone type connectors loose and see if they are corroded at the Zone 2 AC. Doug

I meant to say zone 2 a/c never was worked on

Zone 2 a/c unit never worked Zone 2 model 641815CXXICO Zone 1 model H541816AXXICO

There is a Phone Type cable between the Zone 2 AC control board and the Zone 1 AC control board. THAT is the first thing to check. So, the Zone 2 AC has never been changed or worked on before this problem started? Need the Model number of the AC units. Doug

Yes it worked . I went to turn on zone 2 a/c and nothing happened

need more info. Has it worked before or have you changed something? Doug
