Troubleshooting guide

Dometic OD-5001 rapidly cycles on and off

Use this when an OD-5001 burner starts but cycles rapidly during hot-water 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

  • Open the hot-water outlet enough to keep steady flow through the heater.
  • Clean faucet aerators or shower screens only where they are owner-accessible.
  • Avoid operating the heater below the minimum flow described by Dometic support.
  • Call service if rapid cycling continues after restoring normal water flow.
