Diesel Aqua Hot

This ensures any prior fault is reset since that's one function of the "master" Diesel switch besides winding up the burner motor. I come back later and double-check in the bay that the unit is warm and all lamps are green.....

Are you saying that by turning on the diesel switch first that it will reset a low voltage fault?

Mine does not! Every time I take it to be repaired they turn off the switch. When I need the HH I have to crawl into that little bay and bend myself crossways to stick a tooth pick that I usually forget and end up getting out and doing it all over gain with a home carved tooth pick to reset the low voltage switch! Whooo! Long winded but you get the idea!

Jerry,
Open a paper clip and use it, then leave it on the floor by your HH.

Joel Ashley:
Yes, Larry. I've done it before, both ways, and at least one model's manual says you can do it either way. It was only after reading it in the book I realized I could just use the diesel on/off switch. I'm not sure why Jerry's does not except that models change over the years. That said, some manuals, reviewable in the Coach Assist section of the Forum, indeed only indicate to depress the recessed button in the controller panel. You are supposed to wait 30 secs. after switching the diesel burner off before kicking it on again if you can reset that way. But make sure of course the voltage problem has been corrected or you are on park power.
With a Monterey you have a HydroHot, perhaps an HHE 200 or HHE 500 series the below manual paragraph refers to:
"The Hydro-Hot’s Electronic Controller must be manually reset whenever the Low Battery Voltage fault indicator light has been activated. The Electronic Controller can be manually reset either by depressing the “Low Voltage Reset” button located on the Electronic Controller (use a thin, straight, nonmetallic object to access the reset button through the small hole in the faceplate) or by turning OFF the “Diesel” switch on the Heater’s Interior Switch Panel for approximately 30 seconds, then turning the switch back ON."
Roy, note the "non-metallic" reference, but I think I may have used the paper clip method myself, as I commonly do for any small, recessed reset on a device.

My coach is in the shop for it's spring maint. session. I went out to exercise the genny and everything so I tried the switch as mentioned above. It was off so I turned it on with no activation. So I turned it off for a minute or so and tried again. Still nothing. The elect. does not come on either. So I'm sure I'll have to crawl under to reset it.
