Aqua hot
Does anyone know if the aqua hot system on a 2010 Allegro Bus has a fuse on either the blowers of the system itself. It doesn’t appear to be firing. It was working fine then out. There are green lights on the aqua hot itself but the fans aren’t coming on.

Aqua hot
Make sure you have more than a 1/4 tank of fuel. The system shuts down.

Full tank of fuel. The aqua hot comes on when I run the hot water. It does t appear that my fans are operating. I checked the thermostats by turning the system back to electric from gas. The heat pumps fired up just fine

The fuses are behind the service panel cover. Turn thermostat to 80 deg and run hot ware on full. High demand may trigger ignition.

your heat pumps have nothing to do with the aquahot system. Check all the fuses.

Not true !
You ever try running one of your heat pumps when you have left a zone on 'Furnace' (as in AH)?

I’m talking about the zone thermostats I’m assuming they operate the thermostat for heat and air

The aqua hot is firing. The cozy heat exchangers are not

I think you’re saying that the aqua hot is working fine and is sending hot fluid through the heat exchangers. Problem is that the blowers in the heat exchanger isn’t coming on. IF that’s the case then I’d look for a bad fuse. Where that fuse is located is another question.
Good luck,

The exchangers started working again. On their own. One of the heat vents was inadvertently blocked during some furniture shifting. It could have caused the cozy to overheat and shut itself down. After awhile it reset. That’s a total guess. Not sure why it would have affected the other units. I didn’t find a 12v fuse labeled blowers. I did find one labeled A/C but it appeared to be ok Will continue to monitor
Thanks for everyone’s responses

Normally , the term heat pump refers to the heat side of your air conditioners. And while your t stats are controlling all air functions, hot and cold, they are not specifically part of the Aqua Hot system.
OP if the fan issue continues, I suggest cleaning the t stst connection plug behind the T stat.
