folosem RV refrigerator circuit board 3316348.900 — 3-top 7-bottom pin power module with re-ignitor, AC/DC support

If your RV fridge has stopped cycling correctly or the control board is visibly damaged, this folosem 3316348.900 module is designed as a like-for-like replacement for a wide range of Dometic models. Built with improved materials and a re-ignitor circuit, the board supports both AC mains and 12V DC supply lines and was inspected for better longevity compared with older versions. Before ordering, verify pin counts and model compatibility: this unit specifically features three pins across the top and seven on the bottom and will not replace boards with eight or ten bottom ports.

How do I confirm this board fits my RV refrigerator?

Match the physical connector layout and the control board part numbers on your existing unit. Look for three pins at the top and seven at the bottom; if your old board shows eight or ten bottom ports, this folosem module is not compatible.

• Check the printed part numbers: 3316348.900, 3316348900, 3316348.000 and listed cross-references.
• Compare the bottom connector: this board has exactly seven bottom ports.
• Confirm your fridge model against the compatible Dometic list provided in the product info.

What electrical specifications and power connections does this module use?

The module accepts standard RV electrical inputs: 120V AC (3.5A, 60Hz) and 12V DC (1.9A) to power the control circuitry and re-ignitor. Wiring must follow the fridge manufacturer’s wiring diagram and safety practices to avoid circuit damage.

• AC input: 120V, 3.5A, 60Hz for household power operation.
• DC input: 12VDC, 1.9A for vehicle battery operation.
• Integrated re-ignitor function for gas absorption systems where applicable.

Which Dometic models are commonly compatible with this replacement board?

This folosem board commonly replaces many Dometic circuit board part numbers and supports numerous refrigerator models, but compatibility is model-dependent. It is intended for a broad set of Dometic RM and DM series fridges; still, check your board’s part code and connector count prior to purchase.

• Typical compatible models: DM2652, DM2662, DM2663, DM2852, DM2862, DM3862 and family variants.
• Also listed: RM2351, RM2354, RM2451, RM2454, RM2551, RM2554, RM2620 and others.
• Not compatible with older boards beginning with “293” or boards with 8 or 10 bottom ports.

How difficult is installation and what should I prepare?

Installation is straightforward for someone comfortable with basic RV electrical work and fridge removal. Power must be disconnected before swapping boards; follow the fridge manufacturer’s service manual or consult a qualified technician if unsure.

• Turn off AC mains and disconnect 12V battery before starting.
• Remove the refrigerator control cover, compare pin layout, then unplug and replace the board.
• Verify operation after reconnection and test each power mode (AC/DC/gas) as applicable.

Who is this for: The folosem 3316348.900 board is aimed at RV owners, mobile technicians, and service shops seeking a durable replacement for Dometic refrigerator control modules that use a three-top/ seven-bottom pin configuration. It suits anyone who needs a direct-fit power/control board with an integrated re-ignitor and improved materials for longer service life, provided the original board’s connector pattern and model number match.
