Aqua-Hot

As cold weather arrives, I find the diesel burner on my Aqua-Hot is recalcitrant. It will occasionally fire but after achieving thermostat settings, it shuts down and the switch light goes out. When I turn the switch off and attempt to restart it will not light and the light goes out. Repeated attempts result in the same scenario. The online trouble shooter says first check fuses on the right (forget letter identification). When I pulled the next to last fuse (l-r) it was OK. When I reinserted it the burner fired right up. I have had to pull and reinsert this fuse at least a dozen times on this trip to get heat. The electric element is working fine.
Why does pulling and reinserting a fuse start the burner when the kitchen switch will not? Or, is this fortuitous? Do I have another problem?

Horace,

Without being there, my GUESS is you have a problem which is fixable.  Many things cause the burner to not fire properly but all can be diagnosed with a little work.

If it fires at all, that means the high limit thermostat is good.  So one item eliminated.

I would be glad to assist you if you can run a VOM meter and have the 10 mm socket, extension and ratchet to loosen the J-bolts that hold the burner in place as it will need to be removed to check on other things.

If you wish the assistance, position yourself beside the heater, cover off exposing the burner area, meter and ratchet at hand and then call me at 713 eight one eight 3234.

If we find a faulty part, you repay me by purchasing said part from Roger Berke who has been most helpful to myself and so very many others.

I will second the help that these 2 guys give. When I recently replaced a friends Aquahot total unit with the new one we had a semi major problem with the electric heating side and they came to the rescue on trouble shooting the possible problem. It turned out to not be a problem with the unit but a querk on the Country Coach sytem wiring and secondary hot water tank, but, they called me here in BC every time I emailed them after completing the next testing.
 I have also seen Rogers Trailer/ test vehicle and can attest to the fact "these guys are good". I think the eat and breath these units!!

Rudy, thanks. I have just arrived at my stick house after a one month trip up north. As soon as I get "organized" and a bit of time, I will do what you suggest. In the meantime, I will prevent freezing with the electric unit.

We just had Rudy go over our Aqua-hot and he tweeked a few things and got it working again as it should. We even went out to dinner with him and Carolyn in his new Prius. He knows what he is doing.    Norm

I think this must be his m.o.  ;) Just this Tuesday, ScubaGuy and I met up with Rudy in Baytown to have him look over our AquaHot.  That took all of 5 minutes tops, and after he said everything looked great, he offered us 2 choices:

Option 1. He could charge us to disassemble and then reassemble our already working AquaHot, if we really wanted him to, or
Option 2. We could go and see his Unihome with all the improvements he has made, and then go out to lunch with he and Carolyn in their new Prius.

We went with option 2.  What a lovely couple they are.  It was wonderful for Douglas to pick Rudy's brain.  We had such an enjoyable afternoon with them.  It is nice to know that if we ever come across an issue with our AquaHot, Rudy can take care of us.

That will work IF you have the thermostat set on about 50 degrees - if you try to keep the coach at living temps, the AquaHot will not be able to keep up with temps in the 20's, but it may just sit there and run continuously and let the interior temps drop, including the basement temps.

Duane,
Think your correct when operatoing on only the 120 Volt Element in the Aqua Hot, Why I keep my unit in good operating condition so I do not suffer when the temp drops ointo the -0 area, just enjoy the warmth.

DC, yes I do set the thermostats to 50 degrees, for winter "storage". I have experienced the cold air from the units when on electric only and thermostats set at comfort level.
Thanks,
