If a GFCI receptacle will not set, it is normally lacking 120 volts AC. Start by checking 120 volt breaker panel, reset all circuit breakers. Check for 120 volts to power panel. Next if power is good, remove GFCI receptacle from wall, disconnect load side conductors. See if it resets. If yes problem is on load side. Something like 120 volt element in refer. Try unplugging refer and recheck.
Do you have fluorescent lights in your rig? A bad or going bad ballast can play havoc with some thermostat systems. Try turning off all flourescents. Then reset the thermostat by removing fuse, wait 5-10 minutes, re-install fuse, let system reboot itself. This could take 10-20 minutes. Check to see if the system operates. If it does, there is a problem with lighting. Turn on one light at a time and you may find one that effects the AC/heating system.
Sounds to me like the refer is on with the GFCI issue. Try turning it on in LP mode. I am guessing that the display is lighting up. If the display is not lighting up, you are loosing 12 volt DC control.
