AC unit error code e7

Have a spartan 1239 toy hauler .
AC units quit working and control panel shows error code E7. Outlets that are not gfci are not working. Plugged into 50 amp and power surge proctor shows all ok. Microwave isn't working either .
Checked all breakers and fuses and all look ok .
Any suggestions????

E7 is loss of 120 power with all that's not working possible loose lug on main breaker or bad transfer switch. Do you have same problem with generator running?

Sounds like you've lost 120v on one leg. I had that problem once a a CG. Plugged into their 50 amp receptical and only half of my trailer worked. I used my 30 to 50 adaptor and plugged into their 30 amp & everything worked. Turned out the CG had a bad breaker in their panel. As mentioned above, you may have a loose connection somewhere from your transfer switch to your main breaker.

Front A/C would not work and rear would turned out to be a tripped breaker to the front AC
