Have RV Questions? Ask an RV Mechanic Online.
Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.
Is this a hydraulic system? What happens when you try to move the rooms?
There is none on hydraulic units and pumps almost never go bad. More likely the power to the pump or the solenoid. Easy enough to check if you have a small digital multimeter. About $20 or so at most hardware stores and easy to use. I can direct you in some easy tests. And we can probably bypass the controls and get the rooms in if you have a jumper wire. Let me know.
Just following up to see if perhaps you missed my earlier responses to your question? Easy to do considering the volume of e-mail that most of us get every day! If you need me to resend it please let know. Thanks!
