I have an Imagine 2600RB with a sofa/dinette slide out. It is stuck in the closed position. The forward end moves but not the back one. I tried the reset with the control panel. Did not help. I unplugged both motors on the control and 3 of us could not move the slide. Apparently there is no manual crank for this slide. I cannot access my bedroom or the thermostat. Any suggestions would be appreciated!
