Dometic Penguin II vibration/noise

Just in case anyone can use the following information...
In working through this issue we were informed on how to tell if your Dometic Penguin II low profile ac was updated with the soft grommets at the factory or not.

For Model numbers similar to 641816.XXICO: After week 18 of 2012, they began installing the soft grommets at the dometic factory.
If you have a new penguin II Low profile that was installed around this time frame... this is how you can tell if your unit has the factory installed soft grommets: (Check your serial #)
- The first digit of that number represents the year manufactured
- The second and third digits represent the week that the unit was made
EXAMPLE: For serial # 22524704
The first three digits indicate that this unit was manufactured in 2012, week 25.

Any serial numbers dated before week 18 of 2012 did not get the factory installed soft grommets, so unless they have been installed after factory... you may be having to put up with a lot more noise and vibration than necessary. Call Dometic or see your RV dealer.

Depending on how quickly a repair shop can get to it, it does not take long to do the upgrade. They do have to remove the cover and lift the compressor up.

Dometic covers this under the warranty and there is no cost to the owner.

Hope this helps.
