Roof a/c with not come on, neither will the manual fan setting work. Fuses/breakers seem ok.
I’ve tried both shore power and generator power. Any ideas?

On mine the EMS relay for the AC stopped working. Wired bypass and it works great.

Usually, depending on the Brand EMS, the EMS only stops the Compressor from running not the fan. Intellitec stops full function. PCS brand stops the compressor and not the fan. Doug

I’m the other thread. I replaced both the run and fan capacitors. Turns out my Coleman Mach 15 does not have a separate start capacitor. Nor does it have a speed selector switch. I still have a problem with the high fan option. The high fan wire sparks with power applied. But the air is working again and the fix was pretty easy.
