...what happened when the problem started? Did someone hang a picture, poke a hole somewhere where the thermostat wire may be and got nicked?
Could it be mice chewing on something?
Things don't 'just' break. There is something wrong somewhere and it could be an old problem that finally manifested itself, a wire against an edge that finally wore through or, more likely, something new.
Start with that first; what happened when the problem started?
