Leaking solenoid valve

April 27, 2021, 03:59:34 pm

I have a leaking solenoid valve.

2001 U320

Auxiliary compressor.

Normally open solenoid, air supply from aux compressor to coach.

Any idea of part number or where to buy.

Thanks in advance.

RAP6354

FOT or MOT or HWH

Save the old one and R&R it to have as a spare HWH Solenoid Valve Rebuild

Check to make sure there isn't a problem with cracks in that condensate bowl.  It's common for them to develop at the fittings where the solenoid valve screws in.  If there are cracks, the poly bowl with the HWH purge valve, is P/N PS721P (HWH part number RAP90539). This is a 06L Poly Bowl with 1/8 Connector. You can usually find it in the $30-$40 dollar range on line, closer to $60 at FOT but at least they will have it in stock.

Thanks Michelle

The leaking valve is not the blow down valve attached to bottom of filter.

The leaking valve attaches to the connector below the pressure switch and controls the air line for auxiliary air supply.

In my compressor diagram they look the same, but I have no part numbers to know for sure.

I'll check the blow down valve and see if the info plate is the same.

Thanks again

Steve
