When your Dometic Penguin 15K rooftop air conditioner stops cooling effectively or the condenser fan quits spinning, this is the direct OEM replacement motor that restores proper airflow across the condenser coil. Rated at 115 volts, 1/4 HP, and 1650 RPM with 3-speed operation, part number 3310424.000 is purpose-built for Penguin models ending in .331 or .336 -- no modification required.
The condenser fan motor is one of the hardest-working components in your rooftop AC. It pulls ambient outside air across the condenser coil to reject heat from the refrigerant loop. When this motor weakens or fails, head pressure climbs, compressor temperatures rise, and cooling capacity drops -- sometimes causing the compressor to cycle off on thermal protection or fail entirely.
Dometic part 3310424.000 is the factory-spec replacement for the condenser side of the Penguin 15,000 BTU unit. It installs in the same mounting position as the original, uses the same dual-shaft design, and requires no rewiring beyond reconnecting the original plug connectors.
Engineered specifically for Penguin 15K models ending in .331 or .336. No adapters, no modifications, no guesswork on shaft length or diameter.
Two output shafts (5-11/16" and 4-5/8") allow precise fan blade positioning and secure mounting within the Penguin condenser shroud.
Factory 3-speed winding matches the original control board outputs. Maintains proper low, medium, and high airflow profiles.
Backed by Dometic's limited 90-day warranty against defects in materials and workmanship when installed as directed.
Rooftop AC motors are exposed to UV, road vibration, rain intrusion, insect debris, and wide temperature swings -- conditions that are far more punishing than a residential split system. Bearings dry out, start windings degrade, and the run capacitor (separate from the motor) can cause symptoms that mimic motor failure. Before replacing this motor, confirm the run capacitor checks out; a weak capacitor is a common cause of hard-start symptoms in Penguin units.
Common signs of condenser fan motor failure include: fan blade not spinning while compressor runs, loud grinding or buzzing from the rooftop unit, AC running but not cooling, or the compressor tripping its thermal overload repeatedly.
This motor fits Dometic Penguin 15,000 BTU air conditioner models whose model numbers end in .331 or .336. Locate the full model number on the serial tag inside the AC shroud before ordering. Penguin models ending in other suffixes (such as .531 or .631) use different motor specifications.
Replacing the condenser fan motor on a Penguin unit is a mid-level DIY repair. The rooftop shroud must be removed to access the motor mounting bracket. Disconnect shore power and discharge any stored capacitor charge before starting work. The motor mounts to the center divider panel with a bracket and bolts; the condenser fan blade slides onto the shaft and is secured with a set screw. Typical shop time is 45--90 minutes for an experienced technician.
This listing covers the motor only. The condenser fan blade, run capacitor, and mounting hardware are not included. Inspect the existing fan blade for cracks or balance issues and replace it separately if needed. Reusing a damaged blade on a new motor will cause premature bearing failure from vibration.
The Penguin 15K unit contains two separate fan motors: one for the condenser (outside/top) and one for the evaporator/blower (inside/bottom). This part, 3310424.000, is the condenser fan motor. If your indoor blower is the problem, that is a different part number. Verify which motor has failed before ordering.
After installation, inspect the condenser coil fins for debris, bent fins, and bug nests. A clogged condenser coil will overheat a new motor just as quickly as the old one failed. A gentle coil cleaning with AC coil cleaner and a soft brush extends motor service life significantly.
