Warning Buzzer

I am relatively new as a Motorhome owner (2 yr) and have learned so much during that time about motorhomes. However, I do have a problem that really has me confused. Maybe someone else has had a similar problem that could help me diagnose mine.

I have a 2004 Fleetwood Discovery 39L. When I leave a park and retract the PowerGear Leveling system, I have a long time to wait for the "jacks down" light to go off. Several times I have to shut the system off and then back on to get the "jacks down" indication to turn off. I always get outside to verify that the jacks are in fact retracted fully. Now, once I ensure the jacks are retracted, I disengage the parking brake and put it in gear, I have a warning indicator that starts beeping and all the lights on my leveling system panel start flashing. It used to stop once my air had risen to approx. 120lb pressure and I had no problems from that point. Lately though, the warning buzzer does not go off. I have found that when I am traveling and make a left turn (however slight) the coach leans enough to the right to relieve pressure on the left side and the warning buzzers go off. They remain off until the coach rights itself and puts pressure back on the left side.

Does anyone know if this warning buzzer is tied in to the Air suspension? I do have a "low air" indicator light and warning buzzer, but it does not indicate low air pressure. The Front and Rear Air gauges indicate 120+ lbs of pressure.

Any help would be greatly appreciated.

A number of posts from RVers with HWH systems , replacing return springs for these reasons. Slow to retract & warning lights coming on when driving.
Could be something to look into.

Random idea, but my coach had a similar problem that was solved by topping off the hydraulic brake fluid (just to the "full" line of course).

Check the transmission fluid level in the reservoir with jacks up and slides in. If the fluid is okay, check the float in the reservoir. Power Gear uses the fluid level in reservoir to detect jacks down. They also use transmission fluid, not brake fluid.

Yep, low fluid. Top it off with the jacks up or it will overflow. Also spray your jacks with some silicon when they are extended.

During a turn low fluid will cause the alarm to go off. When it gets low enough it will go off all the time.

I had opposite problem at first. My warning light and buzzer would not work. I found the fluid level very low and added fluid. Still light and buzzer would not work with jacks down. Problem turned out to be a bad sensor in tank. Replaced sensor and system works as it should. If your buzzer and light are comming on with jacks up you are low on fluid (uses transmission fluid) It is probably located in front of passenger side wheel. There will be 2 wires going in one hole and a large plug in another which you remove plug to add fluid. Make sure jacks are in up position and add fluid till you can feel it with a finger positioned in fill hole. Replace plug and that should solve your problem. Hope this helps. Mine is a 98 fleetwood pace arrow.
