Have 40' ft diesel pusher (2001 Monaco) w 2 ac's.  One AC (front) works fine during the day and we turn it off at night.  The other AC (rear) comes on at night and works until early morning (around 7), then shuts off and will not come on again until night.  Had it checked and they say it is fine.  Both AC's are left on auto at 69.  Any suggestions?

It may be the position of the thermostat for the rear unit is positioned so that the temp stays below 69 during the day and when you shut off the front unit it warms and kicks in.  Other thought is there maybe an automatic switch that only allows one unit to operate.

 

Is the electrical shore line connection to park power 50 amp or 30 amp?

Thank you for the reply.  The last few days have been over 100.  The rear unit does not kick in all day long.  It only comes on at night when everything else is off.  We are connected to 50 amp shore power.

Do you have a load share setting in your power management unit that would prevent both running at same time  - ie .. set to only allow 25 A ?
