A little follow-up and to answer a couple of questions.
I found out it is a Duo-Therm Briskair 13,500. I don't know what thermostat he has. It is a wall thermostat and there are no ceiling controls. The problem is not due to freezing. It's been off for two weeks and he's been out several times to run it and it will not come on. He has it plugged into 30 amp shore power so I would say it's not low voltage. Neither the compressor nor the fan will come on after it quits. He's cleaned up the thermostat wires. I told him to climb up and clean-up any wiring up there. I also told him to make sure his 12-volt battery is fully charged.
Any other ideas would be helpful.
Thanks
