Dometic OD-5001 burner ignites but water temperature is too low

Use this when the OD-5001 burner lights but hot water is still too cool during use.

Use this atlas to identify likely meaning and prepare for service. Shut off power, LP gas, fuel, or water when a listed appliance condition involves flame, gas smell, exhaust, generator shutdown, high temperature, moving jacks/slides, refrigerant, 120 VAC, control boards, repeated ignition failure, or a persistent lockout. Call the appliance maker, RV dealer, or a qualified RV technician for repair.

Owner-safe checklist

  • Slow hot-water flow if supply water is very cold and the heater is at capacity.
  • Keep one fixture flowing steadily while checking temperature.
  • Stop use if temperature becomes unsafe or unstable.
  • Call service if the burner lights but the water remains too cool.
