Problem with Honeywell Interface Module THM5421C


Relocated my thermostat, and may have shorted two wires. Could that cause the Honeywell Interface Module (THM5421C) to stop working? If so, can it be fixed, or do I need to replace it?

I short can mess up any board. Does this module have a low voltage fuse on it? Usually on boards that do have a fuse it will be the first to blow in this instance, component protection.
