Squid,

Engine would only be frozen if below 32*F. LOL

To see it the engine will turn, put a 27mm socket wrench on the crankshaft bolt. The engine should turn easily if it is in running condition. If it turns, the problem is in the starter or starter circuit.

There can be a lot of reasons the starter won't crank the engine:
1. Dead battery
2. Bad connection of cables to starter.
3. Bad connection of wire from key switch to starter.
4. Bad key switch.
5. Solonoid not working.
6. Bad starter.

Investigate the above before you try replacing the starter. You can do most of the tests with a simple voltmeter.
