Trane XL20i tripping breaker randomly.

Bought a new home in January and everything has been great... until yesterday. Woke up to see the thermostat flashing its red light and "error 126" on the screen. Did a little research online and found little. Reset breaker (30A) and everything came on and worked just fine the rest of the day and night. Until 5 hours ago. This time 'error 89' and breaker tripped again. Reset it one more time and it held for 5 hours before tripping again. Its staying off for now, though with temps going up to the mid to high 90's (f), I'd really like it running again ASAP. None of the lines are frozen up, filters are new, debris is kept clear. I do hear a faint buzz during initial start up like one of the contactors chattering. Any suggestions? I have an HVAC buddy hopefully stopping by tomorrow but figured I'd ask here as well.
