Key Takeaways

• The Jayco North Point fifth wheel is factory-equipped with a Suburban SW-series water heater, available in both LP gas and dual-fuel (LP + 120V electric) configurations.
• The most common Jayco North Point water heater repairs include thermostat/ECO replacement, heating element swap, and anode rod service — all of which can be performed by experienced owners with the correct parts.
• The anode rod should be inspected annually and replaced when 75% depleted; neglecting this interval accelerates tank corrosion and voids many manufacturer warranties.
• RVIA-certified service professionals recommend draining and bypassing the water heater during winterization to prevent freeze damage to the tank, thermostat, and element.
• Gas-side repairs — including burner assembly, gas valve, or pilot components — should always be performed or inspected by a certified RV technician or licensed plumber.

What Water Heater Does the Jayco North Point Use?

According to RollingRambles’ certified technicians, the Jayco North Point fifth wheel — including 2018 and later model years — is factory-equipped with a Suburban SW-series water heater, most commonly the SW6DE or SW10DE depending on trim level. These units are six- or ten-gallon direct spark ignition (DSI) water heaters capable of operating on LP gas, 120V AC electric, or both simultaneously in dual-fuel mode.

The 2018 North Point RV water heater configuration typically uses the SW6DE (six-gallon, dual-fuel) unit mounted in an exterior compartment on the curbside of the coach. Owners should verify their exact model by locating the data plate on the front face of the heater, visible from the exterior access panel. The model and serial number are required when ordering replacement parts to ensure correct fit.

Suburban SW-series heaters use a screw-in 1440W heating element (part number 520900), a combination thermostat/ECO (energy cutoff) limiter on the electric side, and a separate gas thermostat assembly controlling the LP burner. Understanding which system is malfunctioning is the first diagnostic step RollingRambles’ maintenance team recommends before ordering any components.

How Do You Replace the Thermostat or ECO on a Jayco North Point Water Heater?

The ECO (energy cutoff) thermostat is a thermal safety device that interrupts power to the heating element if the water temperature exceeds a safe threshold — typically 170°F on Suburban SW-series units. According to RollingRambles’ RV maintenance team, a tripped or failed ECO is one of the most frequent causes of “no hot water on electric mode” complaints on the North Point.

Electric-Side Thermostat Replacement Procedure

1. Disconnect shore power and switch off the 120V breaker feeding the water heater. Use a non-contact voltage tester to confirm power is absent before touching any wiring.
2. Open the exterior access panel and locate the thermostat/ECO assembly mounted directly to the tank body, behind the junction box cover.
3. Remove the two Phillips screws securing the junction box cover and photograph the existing wire connections before disconnecting anything.
4. Press the red reset button on the ECO. If the unit immediately trips again under load, the thermostat assembly requires replacement rather than reset.
5. Disconnect the two wires from the thermostat terminals. Using a flathead screwdriver, release the retaining clip and slide the thermostat assembly off the tank.
6. Install the new thermostat assembly, ensuring the sensing bulb or body makes full contact with the tank surface. Reconnect wiring to match the original configuration.
7. Restore power only after the access panel is closed. Test the unit by running in electric mode for 30–45 minutes and checking for hot water delivery at the nearest faucet.

For Suburban SW-series units, RVIA-certified service professionals recommend the OEM-equivalent Suburban Manufacturing 120V T-Stat/Limiter 232306 as a direct replacement thermostat. Based on technician recommendations and verified compatibility, the following parts meet RollingRambles’ standards for this repair:

For owners who prefer a multi-pack thermal cutoff kit — useful for those keeping a service spare aboard — the AMI PARTS RV Water Heater Thermal Cut Off Kit (9-Pack) includes ECO thermostat assemblies compatible with comparable RV water heater configurations. The Dreyoo RV Water Heater Thermal Cutoff with ECO Thermostat Assembly Kit (2-Pack) is another verified option for owners wanting a backup unit on hand.

How Do You Replace the Heating Element on a Suburban SW-Series Water Heater?

When the Jayco North Point water heater fails to produce hot water in electric-only mode and the ECO thermostat tests good (continuity confirmed with a multimeter), RollingRambles’ maintenance team identifies a failed heating element as the next most likely cause. The Suburban SW-series uses a screw-in 1440W element torqued into a threaded port on the lower tank body.

Heating Element Replacement Procedure

1. Disconnect all power and LP gas supply before beginning. Turn off the water pump and city water connection, then open a hot-water faucet inside the coach to relieve pressure.
2. Attach a garden hose to the drain valve at the base of the tank and direct water away from the coach. Open the pressure-relief valve to allow air in and fully drain the tank (typically 10–15 minutes).
3. Locate the element access port beneath the junction box. Using a 1-1/2″ socket, remove the existing element with a steady counterclockwise turn. Do not use an impact driver — the tank threads are aluminum and can be damaged.
4. Inspect the element for scale buildup, pitting, or visible burn marks. A failed element will show an open circuit when tested with a multimeter (no continuity between terminals).
5. Wrap the threads of the new element with two to three layers of PTFE (plumber’s) tape before installation. Hand-thread first, then torque to approximately 20–25 ft-lbs — firm, but not over-tightened, to avoid cracking the element flange.
6. Close the drain valve, remove the garden hose, and refill the tank completely before restoring power. Running the element dry will cause immediate burnout.

Based on technician recommendations and verified compatibility, RollingRambles’ maintenance team recommends the ATEEfaee Upgraded RV Water Heater Elements Kit for Suburban SW Series, which bundles the 520900 heating element, a magnesium anode rod, 1-1/2″ and 1-1/16″ wrench sockets, and PTFE tape in a single purchase — making it a practical choice for a complete service job. For those needing only the element, the Suburban 520900 Screw-In Element Kit (1440W) is the OEM-specification replacement.

How Often Should the Anode Rod Be Replaced on a North Point RV Water Heater?

The magnesium anode rod is a sacrificial component designed to corrode in place of the steel tank lining. According to RollingRambles’ certified technicians, this is the single most neglected maintenance item on RV water heaters and a leading cause of premature tank failure on the Jayco North Point and similar fifth wheels.

RVIA-certified service professionals recommend inspecting the anode rod at least once per camping season and replacing it when the rod is 75% depleted — meaning less than approximately one-quarter of the original diameter remains on the magnesium core. In high-mineral water areas, depletion can occur significantly faster. The anode rod on Suburban SW-series heaters is accessible via the exterior drain plug port and requires a 1-1/16″ socket for removal.

Owners who perform their own element replacement are advised to replace the anode rod at the same service interval, as both components require draining the tank. Doing both jobs in one session minimizes labor and water waste.

How Should Owners Winterize the Jayco North Point Water Heater?

Winterization of the Jayco North Point water heater is a critical seasonal procedure. RollingRambles’ RV maintenance team notes that freeze damage to the tank body, heating element, or thermostat is not covered under most RV manufacturer warranties when proper winterization procedures were not followed.

Water Heater Winterization Procedure

1. Turn off the water heater at least 30 minutes before beginning winterization to allow the tank to cool.
2. Shut off the water pump and depressurize the system by opening a hot-water faucet.
3. Connect a drain hose to the tank drain valve and fully drain the six- or ten-gallon tank. Open the pressure-relief valve to accelerate draining.
4. Locate the water heater bypass valve(s) — Jayco installs a factory bypass kit on most North Point units, accessible inside the rear wet bay or utility compartment. Engage the bypass to prevent antifreeze from entering the tank during the antifreeze flush.
5. Proceed with blowing out the water lines with compressed air (max 50 PSI) or pumping RV-safe propylene glycol antifreeze through the system per Jayco’s owner’s manual procedure.
6. Leave the drain valve open and the pressure-relief valve tab slightly lifted for the storage season to prevent residual moisture from pooling.

RollingRambles’ maintenance team emphasizes that the bypass valve must be returned to the normal (service) position before the first use of the following season. Failure to do so will prevent the tank from filling and can burn out the heating element if the electric mode is activated with an empty tank.
