Componentes OEM comúnmente utilizados en calentadores de agua 5186A

What water heater does the 5186A model number refer to?

The 5186A is an Atwood/Dometic RV water heater model. This collection brings together the OEM components most commonly replaced on the 5186A, including gas valves, thermostats, thermal cutoffs, ECO switches, and burner assemblies. Always confirm your model and serial number on the unit's data plate before ordering to verify the correct part revision.

Are these parts OEM or aftermarket?

The components in this collection are OEM replacement parts sourced to match the original specifications of the 5186A water heater. Using OEM parts protects fitment on the gas train, electrical connections, and mounting points, which matters on a sealed combustion appliance. For related RV winter prep, see our RV winterizing kits.

How do I know which 5186A component has failed?

Common failure points include the gas valve (no ignition on LP), the thermostat or ECO switch (no heat or repeated lockout), and the thermal cutoff (one-shot fuse that opens after an overtemp event). Check for error codes on the control board, listen for the spark at the burner, and verify 12V at the board before replacing parts. If you need help isolating the fault, text or call 817-984-1852.

Do you carry replacement doors and access panels for Suburban and GE water heaters too?

Yes. If you also need an exterior access door, shop our Suburban on-demand tankless water heater doors and GE Appliances RV water heater doors. Match the door by tank size (6 gallon, 10 gallon, or tankless) and confirm the cutout dimensions before ordering.

What is the shipping cost on 5186A water heater parts?

Most small components in this collection (valves, switches, thermostats, fuses) ship standard ground. Orders over $100 ship free. Larger items such as full burner assemblies or tank components may carry a freight charge, which is shown at checkout.
