no power to disconnect box
The contactor burned out on my air conditioner. I changed it out but it still didn't work. When I tested the power coming into the unit, there was nothing so I tested the power to the disconnect box and it is also dead. The disconnect box says "Caution: Does not contain fuses" so I am at a loss as to what to do to get the power back on. I flipped all the circuit switches on and off in the circuit breaker box and this didn't help. 
I live in a manufactured home if that helps. Maybe there is a fuse somewhere or something else that I don't know about?

Welcome to the forums.
That is an un-fused disconnect at the AC compressor. It's basically nothing more than a service switch. It doesn't protect the AC.
In your main panel should be a two pole 30 amp or two pole 40 amp breaker that does the actual protection. Try resetting all the two pole breakers in your panel.
If that doesn't work you will need to remove the panel cover and check the breakers for 240 vac output.

Resetting the breakers didn't help. I took off the cover and the breaker has output. What do I need to do next?

Thanks to everyone for your help.
Yes, I have 240 volts (sorry I didn't make that clear) so that wasn't the problem. It was the breaker switch on the power pole. I didn't check that last night because I didn't know where it was and it was too dark.
