Introduction: The Role of the Dometic Penguin 630035.331 Fan Motor
The Dometic Penguin 630035.331 is a rooftop air conditioner and heat pump unit commonly used in RVs and mobile homes. It’s well-known for its low-profile, aerodynamic design and efficient performance in both cooling and heating modes. At the heart of this system lies a critical component—the fan motor—which ensures proper airflow across the evaporator and condenser coils, allowing the unit to maintain comfortable temperatures efficiently.
Over time, fan motors can wear out due to continuous use, dust buildup, or electrical issues. Replacing or troubleshooting the Dometic Penguin fan motor is essential for keeping your RV’s climate control system running at peak performance.
What Is the Dometic Penguin 630035.331 Fan Motor?
The fan motor in the Dometic Penguin 630035.331 unit is responsible for driving the blower and condenser fan blades. This dual-function design helps circulate air inside the RV and exhaust heat outside the unit. The fan motor is usually a permanent split capacitor (PSC) type, which offers reliable operation and quiet performance.
Key specifications include:
- Voltage: 115V AC, 60Hz
- Current Draw: Approx. 3.5 amps (running), up to 10 amps (startup)
- Cooling Output: 13,500 BTU (typical for Penguin units)
- Compatible Replacement Motor: Dometic Part Number 3309333.007
This fan motor works in conjunction with the compressor and capacitor to ensure optimal airflow and system balance.

Step-by-Step Guide to Replacing the Dometic Penguin Fan Motor
Warning: Always disconnect power before performing any maintenance on your RV’s AC system. If you’re unsure, hire a qualified technician.
Tools Needed:
- Screwdrivers (Phillips and flathead)
- Socket wrench set
- Multimeter (for voltage and continuity checks)
- Replacement motor (Part #: 3309333.007)
- Electrical tape and zip ties
Step 1: Power Down the System
Turn off the RV’s power supply or unplug the shore power cord. Flip the breaker for the AC unit to be safe.
Step 2: Remove the AC Shroud
Climb onto the roof and unscrew the plastic shroud covering the AC unit. Store screws safely.
Step 3: Disconnect the Wires
Locate the fan motor and take a photo or label each wire connection. Carefully disconnect them using pliers or your fingers.
Step 4: Unbolt the Motor
Use a socket wrench to remove the bolts holding the fan motor in place. Gently lift the motor out, avoiding damage to the fan blades.
Step 5: Install the New Motor
Place the new fan motor in the exact position. Bolt it down securely, making sure the shaft aligns with the fan blades.
Step 6: Reconnect Wiring
Match the wires to your labeled diagram or photo. Secure them tightly and use electrical tape for added safety.
Step 7: Test Before Reassembly
Turn power back on and test the unit. Confirm that the fan spins freely, airflow is strong, and no unusual noise is present.
Step 8: Reinstall the Shroud
Once satisfied with the test, shut the system down again, reinstall the plastic cover, and tighten all screws.
