Intellitec 50amp Smart EMS Controller

Had an issue today, my rear a/c tripped the breaker, I reset breaker and a/c came on. Started to smell smoke in coach, removed breaker front panel and saw that the power wire to the a/c had melted and shorted out with the relay next to it. Ordered a new EMS board from Monico to replace tomorrow but wondering there might still be a problem, anyone have any ideas?

Sounds like a poor (ie loose) connection either at the relay or the A/C power wiring. Suggest checking all the AC power connection next time you have ALL AC power removed from the coach.

Agree. Loose connection. Without seeing it, the most likely point is going to be the terminal connecting the circuit conductor. Stay safe and keep us posted.

Thanks to all who posted, contacted Monico, purchased a new EMS board, replaced everything working fine now. Also talk with tech support, just as you all said "was probably just the lose connection that caused it all".

From my experience a lot of times when your A/C breaker is tripped or worst burnt wires it could be that your 2nd stage compressor could have shorted to ground, it most of the time happens at the compressor terminals either L1 or run terminals. But it can also burn wires at the breaker.

Before you start the tripped A/C back up you might want to ohm the compressor motor out to be sure that it is not shorted to ground.

Happy RVing, James
