AC unit trips breaker occasionally on restart when extremely hot out. Will run fine for hours after breaker is tripped back, but will occasionally trip again during hottest part of day when system is cycling often. I have replaced the thermostat, condenser fan motor, capacitors, contactor, breaker, and added a hard start kit. I have also cleaned the coils, cleaned inside of unit, and removed all shrubs near the unit to allow unobstructed airflow. Any suggestions? Iím thinking high head pressure or possibly upgrading to a 40 amp. breaker (assuming I have a 30 and the unit allows for a 40 Ė need to check on that)
