HWH air pump running.

I just bought a 98 Magna. When I level the small motor under the drivers seat compartment runs for a long time. Is this normal? Thanks, Ray

With my 2000 Magna, I usually don't dump the air out of the bags prior to leveling unless I want to put the entry steps closer to the ground. I level while the engine is running and then put out my slide and recheck level. Leveling this way does not use the HWH pump since the engine compressor is supplying air.
Should I dump the bags, I still do the initial leveling with the engine running, then extend the slide.
The HWH air pump will run when the engine is off and one pair of air bags needs to be inflated to level the coach. If the main air tanks air pressures are low, the HWH pump will run for about 15 minutes, then shut off without leveling the coach. The HWH control panel will then show the excess slope light. I believe this is happening because the small HWH air pump is trying to fill the main air tanks as well as inflate the appropriate air bags because the system works fine if the main air tanks have 100 psi or so of air pressure.
PS It helps others respond if you list your coach number with your post.

Do all your leveling with the engine running. Works so much better.

I have a 1998 CC Magna #5489 and I typically level with the coach running in order to have sufficient air. The aux pump is used to re-level the coach periodically when parked. Usually the amount of adjustment required at that time is not extreme but, even so, the pump can run for 5 to 10 minutes. The pump that you are talking about is intended to correct for small changes and is not up to the task to perform the initial leveling. I have not seen this in writing but it works for me.
BTW I usually shut off the leveling system and only turn it on when I notice a problem. This limits the noise and reduces battery drain.
