Title: Johnson Controls A419 Problem
Post by: CREW1 on February 04, 2013, 05:25:10 PM

I set my JC A419 set point to 179f i set the dif to 15 the asd to 1 the OFS to 0 and the SF to 1

It was functioning fine for a full day....fan kicked on around 164f and kicked off around 178f

A little while ago it ran a normal cycle and started to cool....at 172f the blower fired ????

Wondering if anyone knows why? Possibly a defective unit?

Thanks
