Furrion tankless water heater freeze mode or freeze damage

Use this when a Furrion tankless water heater shows freeze-protection behavior, Fd winter-use mode, or visible freeze-damage/leak symptoms after improper winterization.

Owner-safe checklist

  • Shut off water, LP, and power if the heater is leaking or visibly damaged.
  • Do not rely on freeze-protection mode to winterize the entire RV plumbing system.
  • Photograph visible damage, the display state, model label, and winterization history for warranty or service.
  • Contact Lippert/Furrion or a qualified RV technician before operating a suspected freeze-damaged heater.
