If you have ducted air conditioners now and replace them with the same
I don't see why any thing inside like grates or grills would need changing .

Depending on HOW the upper unit is connected to the duct system, may require modification on the hole in the roof on the topside. Usually, only Newmar Motorhomes have this problem from the OLD Penguin to new Penguin. Doug

Ok I'm done. Tried to beat on it with a rubber mallet while it was trying to start..nothing.
Went to the ac supply house and picked up a hard start kit...nothing.

Did you see what the voltage dropped to when the AC unit tried to start? Perhaps the voltage is dropping below that required to start the compressor. Just a thought.

Ordered two new Penguin 15k with heat pumps yesterday. Rear ac is working good but want both to be the same. If anyone in ct area can use a ac or some parts it's yours.

Mike , Did you order a new thermostat too ? I'm pretty sure your old
one will not cooperate with the new units . The new thermostat is plug
and play same as the old one .

Your old thermostat may be worth more to someone than the old A/C units .

Measure the spacing of the 4 long bolts . Mine was slightly different
by just a small amount and I didn't know it , caused me a little grief.
I had to enlarge the holes a little where the bolts pass through
Good luck

Hey Doug my coach has a hose for each of the ac's so the water drips on the ground near my front tire and rear bumper instead of running off the roof.
Is their a way to do that with these ac's?

Not Doug but I think I can help .
That part of the units is an added part . It is 2 little plastic pans
that attach to the underside on the outside of the unit
They are held on by 2 screws and can be moved from the old A/C
I was concerned the plastic pans were old and fragile so I ordered
new ones . This is the kit, if it was me I would order 2 kits

Thanks Dave. I didn't see any installation instructions but I'm guessing sence I allready installed the units I need to unbolt them from roof to install them.

I would purchase 2 new drain cup kits from Dometic. After all these years the Plastic will be very brittle and will probably crack. That is what I would do if I was doing this for myself or a customer. Doug
