hi if the unit has controls on the ceiling assembly there are no 12volt fuses, however, there will be a 120vac breaker. so you need to check the breaker panel for power, then go to the ceiling panel and see if there is power there.............i say this as in a 'pop up' there is usually no wall thermostat if my thinking is incorrect, please let me know, thanks please get back to me and we can discuss this further
