2011 tiffin open road 32ca - while camping and living room slide out was out and when trying to retract slide out it had NO power? Once we turned off the 12v system and then turned back on side came in as normal. Anyone know what would cause this? thanks

Maybe a circuit breaker (or similar overload protection circuit); there are some that self-reset by having their power cycled.

Automatic CBs do just that. Most overheat with excessive amps and take time to cool off and reset. Measure the amps traveling in both directions and if excessive you might have a CB or slide issue or loose wire, low battery, etc. Resolve ASAP.

What is your battery voltage taken off the battery with a volt meter.

Is this slide hydraulic or electric operated?

Yes, moves great once the couch 12v power switch is toggled off then on again - that is what I don't understand?

The problem is your HWH hydraulic pump master solenoid is starting to go bad. Here is a replacement HWH Master Solenoid.
This solenoid mounts directly on the pump motor. While your at it get 2 and replace both solenoids on the motor at the same time to prevent other problems later.
