Availability of Soft Start for Dometic FreshJet 5

Published 09/02/2025

Question:

Im installing the Dometic FreshJet 5 15k BTU with heat-pump roof top air conditioner onto my Airstream. Even though the just-released FreshJet 5 air conditioner has an integrated hard start Id like to add a soft start too they work better for my use on a 30amp RV combined with a 15k BTU AC The specific Dometic Soft Start DMC87RR says its for the FreshJet model. The newest FreshJet is model 5 replaces the old FreshJet 3 model. Do you know if part DMC87RR is compatible with the newest new FreshJet 5 models?

Hey Mike, great question! I reached out to Dometic and they said the Dometic Soft Start for FreshJet Mechanical Air Conditioners # DMC87RR is also compatible with the FreshJet 5. You can use this to add a soft start to your new AC unit.

Any big trips coming up with your Airstream this fall?

Thank you and great to learn. I appreciate you reaching out directly to Dometic to confirm compatibility. Next Airstream adventure is the Florida Keys in a couple months.
