and hopefully the final update...
I have A/C!
Since everything on the roof looked good, all connections looked good, fan/motor spin freely, etc. I figured it couldn't hurt to do some exploring inside. So, I took the inside roof panel off and started exploring. The error code was for either and open circuit or an out of range freeze sensor so I focused on finding said sensor. Traced it back to the circuit board box and removed and cleaned the plug. Pressed it back into place, closed up the wiring and switched on the breaker. Et voila! Fan started with NO E5 CODE! About 15 seconds later the compressor kicked on and cold air started blowing.
It's been running for about two hours now, cycling off and on as it should. I'm going to leave it on all day to make sure that was the fix and not just a coincidence.
Still not sure why the error was intermittent, maybe it had to do with expansion/contraction during the day. I don't know. Anyway, the capacitor was bad, the A/C is now working and I have a new EMS on the way.
REPLACE THE FREEZE SENSOR! It will malfunction again. Doug
