Aqua Hot REPAIR in Salt Lake or Eugene?

Folks,

I have been fighting problems with this system for years. I've worked with Roger Berke and he has been helpful, but the same FTF problem always returns. I'm ready to get other eyes and hands on it.

Do any of you have any experience with the following Aqua Hot Authorized Service providers?

Sonny Clark Mobile Service - Salt Lake City/Ogden
Affordable Mobile RV Service - Eugene
Carrier & Sons - Eugene
Innovative Coach Works - Junction City

We are in SLC through Wednesday and then in western OR for several days.

Thanks,

Your coach is very closely related to mine. Is your AH a 100-02s? What is your recurring problem?

Hi Steve,

The major issue is failure to fire (FTF). The secondary problem is that it turns off after completing a normal cycle.

Over a couple of years I have replaced the controller, the black thermostat and the C harness, all in an attempt to fix the FTF problem. All "worked" for a while but it keeps reoccurring. It will run flawlessly for days or weeks, then not. Cycling the switch never causes it to recover.

(The motor also has been rebuilt by Roger Berke, and I replaced the fuel pump for different problems)

I have done the fuel flow, thermostat, flame sensor and igniter tests numerous times and the unit always passes. After testing it works fine again for a while.

It seems like it has to be electrical, and related to the igniter not firing, or not being told to fire.

Oops: yes it is.

Wow Bob,

That really sucks! Intermittent problems drive me crazy. It does sound like in must be electric. I think yours is a version newer than mine. Do you have the electronic board with the led indicators?

I would never try to second guess your efforts to resolve this problem but in turning it over in my mine the following possibilities come up:
1. The controller. I know you replaced it but could some condition be causing a fault in it. Did you replace the C harness before or after the controller? Does your unit have the separate wire with a diode that keeps current from back feeding from the stir pump to the controller?
2. Possibility of a wire pinched or broken. The harness passes close to areas which are very hot and also through grommets into the burner chamber.

The secondary problem of turning off after a cycle. Does this mean that the light at the burner switch is off & you have to manually cycle the switch to turn it back on? I can't help but think the problems are somehow linked but can't say how. I think your unit is electronic in this regard & mine is purely analog.

At any rate, don't give up. The answer is out there.

EDIT:

I forgot to say, there is a Bosch relay over in the front run bay that is labeled AquaHot. I don't know for sure, but I suspect that it's between the switch and the control box. If that relay is intermittent that would interrupt power to the box.

Also, when it fails to fire, does the motor/blower run but doesn't ignite?

Bob,
Had Carrier & Sons install some electronics in my coach last fall. Nothing like your problem, but they did a solid job, at a reasonable cost and time frame. Wouldn't hesitate going back to them if, when the time comes.

Hi Steve,

I appreciate your help.

Nope, same model as yours without any display. In order:
1. I am leaning that way, too. The harness was replaced several months after the controller. Yes, it does have the diode wire.
2. I have looked for pinched or broken wires a few times but didn't see any. The C harness replacement was a "hope" fix, not based on any real data, just frustration. I have looked at all of the individual wires in the connectors and none showed any sign of being faulty. I have tugged on every wire I can find and tightened every connection I can see at least twice a year.

I just cleared the problem again by, a. testing the thermostat continuity (good), and b. plugging and unplugging both connectors on the controller. It took about 30 seconds to fire but it did and ran through the full cycle. The light on the switch did go off when the cycle completed, but went to the ready state when cycled.

About all I can think of beyond the controller is the flame sensor. It static tests good but Roger says that test isn't conclusive, it should be tested when the burner is running, something I can't do in the field. I can't imagine the igniter can be intermittent. When the system fires, I hear click and then ignition happens. It has also worked robustly every time I've tested it.

I wish Roger made house calls.

I used this place for a chronic check engine light problem and they fixed it.

Made an appointment, took it in and three hours later it was ready. So i recommend them.

On another issue....where are you staying? KOA or Shadow Mountain?

Had the same problems with mine, back and forth for repair driving me nuts. Finally changed the coil for ignition and problem gone. Give that a try. Never could find a number for resistance on old coil so just bought a new one as there was nothing else to change.

Thanks Arch, that's good to know.

We have been at Pony Express since mid-July. Nice park, great management. A little pricey, though.

Cheers,

Mh, interesting input, thanks. If I decide to through more parts at it, the two at the top of the list are the igniter and the flame sensor. I was leaning toward the sensor because I wasn't confident that my testing was conclusive. I am hoping that one of the authorized service folks will have a controller tester before I resume guessing.

Cheers,

If the unit lights and runs, itís not the flame sensor.
