Sometimes it turns on then it shuts down before it would shut down and I would turn it on then it would work till I shut it off
Check power supply board and inverter board for faulty solder connections and visually inspect electrolytic capacitors for signs of stress or failure. Bulging tops, black or brown crusty material oozing out of them, are the most common. Replace those that are visibly faulty with high ripple current types.
If that does not resolve it, the next step is to test the transistors in the 24 volt section and inverter section primarily. Recapping the power supply 24 volt section is prudent regardless of physical appearance of the electrolytic capacitors.

The power supply may have gone out, that is the first place to look, look for blown fuse, burnt parts, bad capacitors.
