RVComfortZC thermostat backlight not lighting up
We have a Rv Comfort ZC black thermostat in our 5er. When we pressed any button on it, it used to light up. Now when we do this, nothing lights up any more making it hard to see at night. What could it be?
Also, how do you take off the cover for this thermostat without breaking the cover? I've tried to take it off, but am afraid I will break it.
Is there a fuse that I need to check?
