Experience: I was a rockwood camper dealer for many years from 1970 on many years Servicing motor coachs, rv's and motor homes.
The sensors are located between #3 and #5 on the left head and #4 and #6 on the right head, i am sure at this point that the left sensor is temp and the right is a fan switch. Thanks for you're help
