HWH Reset and Auxiliary Compressor

September 21, 2010, 01:18:13 am

My FT sets right outside my home on a nearly level site, hooked up to continuous 30amp shore power, in a damp environment. The effects of this year's La Nina in the Puget Sound area are well underway. I'm including these facts in case they might be related to answering my questions.

But I took advantage of an only slightly rainy day two days ago to give the coach a thorough washing. While I was rocking the rig from the roof, the auxiliary air compressor went on. I took the rocking and the compressor starting up to be related events, probably expectable, to correct some small error in leveling exposed by my motion.

Forty-five minutes later, the compressor was still running. This didn't seem right, and in what was by then a downpour, I could not detect leaks by my cursory listening to the air bags and slide bladder. On my way to look at the compressor, and perhaps to disconnect the in-line fuse there as a temporary fix, I decided, on impulse, to first see what would happen if I hit the HWH reset button in the coach. I punched the button - and the compressor went off. Coach was level at that time, and still is. Compressor has not restarted on its own, and I have not yet dropped some air from the bags to test if it will start again, and if so, stop inself when appropriate. Fortunately there has been good recent discussion of the compressor on this Forum, and I will use it to help me if things don't seem right.

But here are my questions now. Were hitting the Reset button and having the compressor go off related events, or just a freaky coincidence? If related, was it predicatable? If predicatable, is the relationship purposeful, benign, or can I expect some negative consequence from this action?

HWH LIGHTED RESET SWITCH
The HWH lighted reset switch is located on the shifter panel.
If there is a failure at any time in the HWH CAN network, the network will shut down.
The leveling system and all room extensions will not operate.
If the ignition is off, no indicator lights will come on.
If the ignition is in the "ON" position, the lighted reset switch and the MASTER WARNING Light will come on.

If the lighted reset switch is on, the switch must be pushed before any room or the leveling system can be operated.

If the operation of the room is halted and the lighted reset switch is on, there may be a problem with an unlock limit switch. The room mechanism should be checked and repaired before trying to operate that room again.
Operating a room with a lock extended may cause extensive damage to the room.

Excessive operation of the hydraulic pump can shut the HWH CAN network down.
The lighted reset switch will be on if the ignition is on. The reset button must be pushed before any operation can continue. Allow the pump to cool before continuing hydraulic operations

A network problem with one room will not inhibit the use of the other rooms or leveling system after the reset switch is pushed.
A network problem with the leveling system will not inhibit the use of the room extensions after the reset switch is pushed.

If the lighted reset switch will not go out when pushed, there is a problem with the central control module of the network system. No rooms or the Leveling System will operate. The vehicle suspension will return to the travel mode if the ignition key is in the "ON" position

CAUTION: IF THE IGNITION IS IN THE "ON" POSITION AND THE LIGHTED RESET SWITCH IS ON, THE VEHICLE CAN RETURN TO RIDE HEIGHT WITHOUT RELEASING THE PARK BRAKE.
