thermostat won`t read room temp

Friend has a Coleman-Mach digital thermostat #6636-3441 that reads the room temp as 0 degrees. Consequently the a.c. doesn't work. Any ideas?

I've heard two different things on this.

1. Pull the fuse and wait 5 minutes to see if it resets itself.
2. There is electrical interference somewhere else in the coach. In that case you should turn everything else off except for the A/C and see if that works. Then start trying to turn other things on and see what is causing it.
