Jacks tripping breaker

Hey everyone!

So my father passed away a year ago, and my mom parked her 2018 Dynamax Forest River Isata Series 4 Super C on our asphalt parking lot for approximately 4 months with the jacks down. I told her to retract them every so often, but she didnít.

Now when I retract or lower the jacks, the breaker under the front door step trips after about 20 seconds. I believe it is a thermal breaker. There is a full reservoir for the jacks, but there appears to be slight fluid residue at the back of the pump. However, it will raise and lower until the breaker trips.

Iím not sure what the problem is. The nearest service center for warranty work is over two hours away, and Iím hoping I can just do a simple fix as Iím mechanically savvy to a degree. Any ideas?

Thank you!

Are the batteries fully charged at 12.6 to 12.7 volts each? If the charge is low the pump will draw more amps when running causing the breaker to trip.

They appear to be at 14.7 for the cargo hold batteries. It also has solar charging. It is an 80amp breaker
