What's wrong?
The inverter in a 2021 Forest River Berkshire motorhome changes stored battery power into household-style electrical power for coach equipment. On these motorhomes, the Magnum 3000W inverter was installed with 10 gauge Romex wiring. That wire size has to match the current the inverter and breaker allow through the circuit.
On affected Berkshire motorhomes, production used the incorrect wiring size when switching from the older 2000W inverter to the 3000W inverter. The newer inverter had a 50 amp breaker, and the existing 10 gauge Romex wire was not sized for that current. Forest River determined the setup needed heavier 6 gauge wiring, a 12V disconnect, and 50 amp breakers, or a lower-output replacement inverter.
Forest River lists no warning sign before failure. There is no warning sign before failure, so an owner should not expect a dashboard light, sound, smell, or appliance change before the wiring is overloaded.
Who's affected?
Both component labels point to the same Magnum 3000W inverter.

What's the safety risk?
The concern is overloaded wires and an increased risk of fire. Forest River lists no warning sign before failure, so use unusual electrical smells, heat, or smoke as a reason to stop using the vehicle and call the dealer. Repair is free at any franchised Forest River dealer.

- Bring the recall notice if Forest River mailed one. If not, reference recall number 20V540 when you call.

- Call Forest River customer service at 1-754-533-5934 with questions.
What happens at the repair
At the dealer, a Forest River technician replaces the original 3000W inverter with a 2800W inverter so the electrical load matches the wiring covered by the recall. The replacement parts and labor are free under the recall. Forest River's general reimbursement plan covers eligible documented out of pocket repairs paid before the recall notice. Bring receipts or repair paperwork to the service desk and ask how to submit them under that plan.
