AS WITH ALL MY VIDEOS I TRY TO GIVE THE MOST INFORMATION IN THE LEAST AMOUNT OF TIME AS POSSIBLE SO I DON'T WASTE YOUR TIME. IN THIS VIDEO I HAD MY THERMOSTAT IN MY 2007 WEEKEND WARRIOR START ACTING UP. IT WOULD INTERMITTENTLY TURN ON THE FURNACE EVEN WHEN THE SWITCH WAS IN THE OFF POSITION KILLING THE BATTERIES IN MY CAMPER. I GO OVER HOW TO REPLACE THE THERMOSTAT AND HOW YOU CAN DIAGNOSE WIRING ISSUES TO THE THERMOSTAT AND THE THERMOSTAT ITSELF.
