mobile aqua hot in Tucson
my Aqua Hot started making strange sounds yesterday. When burning fuel it hums along. But when going through the cool down sequence. The motor makes more noise the closer it gets to shutting down.

was wondering about everyone's experience with...

It was doing that when you were parked next to us. I also smelled fuel. I thought that was normal, so I said nothing. Good luck!  ^.^d

I know it needed a routine service and planned on that...

we had Ken Cameron and his wife work on our AH the day after we bought the coach. He's quite the character.....but knows his stuff. She knows as much too. You will be in good hands.

If it keeps running on and off, it is the "brain box". Send Rudy a PM.

If you need Aqua Hot service in Tucson, like Glenn, I recommend Cameron's Reliable Maintenance Mobile Service (520) 490-7632. Ken and Rachael do excellent work. They fixed my Aqua Hot several years ago. When Rachael emerged from the AH...

I agree to call Rudy, he recently helped me on the phone to diagnose and repair my problem which was a bad control box.  I ordered a rebuilt unit from Jim Frerichs and got it in a couple days.  There are also troubleshooting guides on Roger...

What's odd is that while it's on the burn. It runs smooth and steady. It's only after the flame has gone out that the odd...

bigdog that in my opinion is not normal, mine does not do that when it is cooling down.

Bigdog,

I don't know if you are aware that the factory rebuilt units are the boiler only. Pumps and burner assemblies are tested, repaired where needed and reused. I replaced the blower bearings in my unit within five years. There is no way the...

This guy was in Phoenix two days ago, he's mobil and had just come from Quartzsite. He repaired a friends AH the same day. Lloyd told me that he had the parts inventory and if he couldn't fix it. It couldn't be fixed.    A pretty tall claim if...

Rudy said the blower bearings last a long time until they fail.  We replaced mine a few weeks ago, the hardest part is getting the motor case off, a tight fit.  And you need an internal spring ring tool.  It pretty obvious if the motor is bad or...

A zillion years ago I briefly sold pools.  Part of the heaters design was to run the circulation motor after the heater flame shut off .
Stopped the banging noise when the water in the coils was boiling as the tubes were hot.

Called it a deadman's...

The motor will run for a minute or 2 after the burner shuts off to cool off the combustion chamber.  The motor sound may change since it doesn't have the load of the fuel pump, also with less load you may hear a chatter from the clutches.
Can you...

It was not that bad when you were here, but I heard the same sound (quieter) when I was in my chair close to your coach.

If the noise is just a varying pitch, as it the motor speed is changing then check geound wires at the post on the AH and the power connections. If there is a loose connection somewhere voltage may vary a bit causing motor spreed to change.

Prognosis isn't good on my Aqua-Hot (AHE-100-02S)

Cameron from Cameron's Maint. as well as Rudy both say that the "brain Box" isn't so brainy anymore. It's starting to fail but still works at the mo. Fortunately my AH has the preferred old style...

The price of a rebuilt silver box is extreme, to say the least. Of course,   they no longer make the silver version. You can buy a new " black" box, not made in Germany, and then take your chances that it will work properly. I am disappointed...

A rebuilt silver box is less than half the price of the previously available new one. You might look online or in the ForeForums classifieds.
