HWH hydraulic leveling system

I have a 2015 Tiffin Allegro RED QRA
When getting ready to leave Florida I found passenger side front slide and Leveling system wouldn't work. After taking to Tiffin Service Tec. And told I could jump the wires on the master solenoid to get the slide in and jackes up which I did. I bought another temporary solenoid from a truck parts shop on hopes it might get us back home. It didn't. It Burned up the next day. I have ordered both the master solenoid and one for the pump as well.
My question is could there be another problem that caused it to burn up. Even though the master solenoid does say Continues Duty on it ?

How many amps is your pump motor pulling--how many amps is your replacement solenoid rated for? The answer to one or the other is the solution.

Yup, CONSTANT DUTY solenoid of the proper amp rating is what you need. That is a bit of an unusual "failed twice" devices. Usually, an overload will take out the fuse/breaker.

The solenoid you bought at the truck parts store wasn't rated for continuous duty at 150 amps with a peak load at 800 amps. That's why it didn't last more than one day. These master solenoids will normally need replacing every 5 to 7 years if you are using the slides every two or three days.

i will have to confirm that azpete is the acknowledged expert on HWH systems. He was a tremendous help when my system lunched a pump motor! He found one, 3 ay shipping at reasonable price! Thanks again Paul!
