Is it possible for a central air unit to run at 115 v 15 a?

The specs are 208/230 volts 60 HZ it says 11.4 a for us, and 30a for Canada. It was connected to 110 and 15 amps. The AC was working, until a week ago. It only worked in the on position, not the auto position. Can the motors voltage be rewired internally, like a water pump? (the AC does not say 115/230) Would putting in a 230/30 breaker fix the problem?

It is definitely 1 single breaker.

They still make double pole breakers with a single leaver.Check the voltage at the panel.Like the man said I don't know any 110v. central unit.Window units yes,central or split units ,no.You should have two hot wires and a neutral or ground going to the unit.

Cant explain why it worked at all.
115V. might run the fan, but not the compressor.
Are you sure it's not connected to two single pole breakers?
