Atwood heat pump

[CSroo]

we are enjoying our 32 DS but having trouble with the rear heat pump Atwood air command. It won’t turn on even with the thermostat set to 85. The AC seems to still work, Fan, etc. The living room AC and heat pump work fine

I am only hooked up to a 15 amp house circuit but The only thing I’m turning on is the back heater

Any troubleshooting suggestions?

Try repeating the process with your generator on. That would eliminate a voltage drop as being lhe problem.

What’s the ambient temp?

The furnace in my 32ds is only controlled from the front/living room controller. I thought that was normal.

I will try it with the generator on. Good idea.

My furnace is controlled with the front thermostat but the Atwood air-conditioners have heat pumps – – at least I’m hoping both of them do

It’s still mid 50s here so I think the heat pump should work. The front one was.

Thx

If you only have 15 amp service, I think your marginal on the power supply. If the battery charger or any other device is using 120v, I'm not sure if it'll start. Connect it back to generator for a moment and see if it'll run on the generator. And it does take a min or two for the fan to kick on too.

My 2017 30DS only the front unit has the heat pump. You can climb onto the roof and look at the emblems for that info.

Thanks for the replies. Moving to 50 amp circuit didn’t help. I’ll climb up and check Atwood to see if it has the heat pump on the second.

Only my front unit has the heat pump. Look at your model numbers that will tell you if it has the heat pump.

What is the advantage in using the heat pump vs. the furnace?

[GM_LA]

Saving your propane . But remember the heat pump will not work once the temperature drops below a certain degree. I can't recall what that is.

[CC Traveler]

Use of the heat pump saves your propane and is good to knock the chill off down to around 40 degrees.

How do you tell if a unit has or does not have a heat pump? Is the model number under the cover? I have a 2017 32DS both wall mounted controllers inside for each a/c are identical. New to the heat pump idea but now I am intrigued. Thank you for any info.

While I haven't looked myself on our newly installed Atwood AC in the rear, I know on our Dometic AC unit in the front, you can pull down the interior trim/filter cover and look up from the bottom. You'll find a label that'll have a PN and/or a 13.5k/15k specified. From the top of the RV, I think there is just 4 screws that hold down the exterior shroud, might be easier to do that...

The specs online for a 32DS aren't very clear, so you could have a 13.5k unit in the rear (which I'd expect for them to save $$$), which would be a non-heat pump version. Front unit is advertised as being the 15k with heat pump though.

This is what we were told also on our 18 31L5. Only the front has heat.

[CC Traveler]

The front unit should be an Atwood Air Command model AC 1511 to have the heat pump. The rear unit is model AC 1361 w/o heat pump.

Thanks for replies. Keeping warm with the front heat pump and a space heater
