It could be it is still 60Hz, but an extremely crappy or dirty
waveform is tricking the meter. That might change the diagnosis/
troubleshooting procedure.

The fact that you could run your table saw and band saw, make it
unlikely that it was really 400 hz. The saws would be running at
about 7 times their normal speed if it were really 400 hz.
