Frequently Asked Questions

Are you an authorized Dometic dealer?
Yes, Accumar Marine is a fully authorized dealer and service center for Dometic marine air conditioning systems. Our technicians receive factory training to ensure we are up-to-date on the latest Dometic technology and repair protocols. We have the diagnostic tools and genuine parts to get the job done right.
What are common issues with Dometic Passport I/O units?
Some dock talk revolves around Passport I/O units having control board failures or refrigerant leaks. Often, it's just a clogged sea strainer or a tripped breaker. We can quickly diagnose the real issue, whether it's a simple fix or something requiring a more in-depth repair on the hard.
How often should I service my Dometic DTU unit?
For a Dometic Turbo (DTU) unit to run reliably, we recommend an annual check-up. This includes a full system flush, cleaning the coils, checking refrigerant levels, and testing all electrical connections. Proactive maintenance prevents costly emergency repairs during peak season and avoids a frustrating turnaround day.
Can you get parts for older Dometic and Cruisair models?
Absolutely. As an old salt in the marine business, we have extensive sources for Dometic and Cruisair parts, including for legacy systems. We stock a wide range of common components and can quickly source harder-to-find items to minimize your vessel's downtime.
My Dometic AC is showing an error code. What should I do?
First, check our Dometic error codes page for a quick diagnosis. If it's a simple issue you can resolve, great! If not, or if you're not comfortable troubleshooting, give us a call. A bilge rat might just start swapping parts, but we use proper diagnostics to fix the root cause.
