Keep your Bradford White M45036FBN water heater running safely and efficiently with genuine OEM replacement parts from Repair Clinic. The M45036FBN is a 50-gallon natural gas water heater from Bradford White’s Defender Safety System series, featuring the ICON System electronic gas control with piezo ignition and thermopile, Vitraglas enamel tank lining, Hydrojet cold water inlet tube, and ScreenLok flame arrestor. Like the RG240T6N, the M45036FBN uses a thermopile rather than a traditional thermocouple, a distinction that changes the pilot-out diagnosis from thermocouple testing to thermopile millivolt output testing. Repair Clinic stocks genuine Bradford White OEM parts for the M45036FBN including the ICON System gas valve, anode rod, dip tube, and T&P relief valve.

M45036FBN: Defender Safety System and the ICON Electronic Gas Control
The Bradford White M45036FBN uses the same ICON System electronic gas control as the RG240T6N, including the Defender Safety System ScreenLok flame arrestor and resettable thermal switch. The ICON System’s green LED diagnostic indicator flashes a code identifying the fault when the system fails to ignite or maintain pilot, a feature that distinguishes this model from simpler standing pilot water heaters with no diagnostics. The thermopile on the M45036FBN converts pilot flame heat into electrical power for the gas control valve, and thermopile failure is the most common reason the ICON System’s LED indicates an ignition fault. The water heater repair help section covers ICON System thermopile testing and LED diagnostic code interpretation.
Most Replaced Parts on the Bradford White M45036FBN
ICON System Gas Valve for the M45036FBN
The ICON System gas valve on the M45036FBN controls pilot and main burner gas flow and contains the microprocessor that displays diagnostic codes through the green LED. A valve that fails to maintain pilot, fails to open the main burner on demand, or has a failed thermopile connection requires replacement with the OEM Bradford White ICON System valve to preserve the diagnostic capability.
Thermopile Assembly for the Bradford White M45036FBN
The thermopile converts heat from the pilot flame into the millivolt electrical signal that powers the ICON System gas valve. A weakened thermopile causes intermittent pilot outages that worsen as the thermopile continues to degrade. Testing output with a millivoltmeter at the gas valve terminals confirms whether the thermopile is producing adequate power before the valve is condemned.
M45036FBN Anode Rod
The sacrificial magnesium anode rod in the M45036FBN’s 50-gallon Vitraglas-lined tank protects the steel tank from internal corrosion. At 50 gallons the anode rod is longer than in a 40-gallon unit and may degrade at a different rate depending on water quality. Inspect every two to three years and replace when heavily corroded.
Dip Tube for the M45036FBN
The Hydrojet dip tube in the M45036FBN is engineered to reduce sediment accumulation and improve first-hour delivery by creating a turbulent mixing action at the cold water inlet. A cracked or broken dip tube allows cold water to short-circuit to the hot outlet, producing inconsistent hot water delivery symptoms that resemble a failed burner or thermostat.

Bradford White M45036FBN Water Heater Parts FAQ
What is the Bradford White M45036FBN and how large is the tank?
The M45036FBN is a 50-gallon natural gas atmospheric vent water heater from Bradford White’s Defender safety system series. The 45 in the model number indicates the approximate BTU input, and 036 identifies the series production configuration.
Does the Bradford White M45036FBN use a thermocouple or thermopile?
The M45036FBN uses Bradford White’s ICON System with a piezo igniter and thermopile to power the electronic gas control valve. It does not use a traditional standing pilot with a thermocouple.
How often should I replace the anode rod on a Bradford White M45036FBN?
Inspect the anode rod every two to three years. Replace it when it has corroded to less than half its original diameter or when more than six inches of the steel core wire is exposed. The standard rod is magnesium; an aluminum alternative is available for areas where the magnesium rod causes sulfur odor in hot water.
Why does my Bradford White M45036FBN pilot go out repeatedly?
On the ICON System M45036FBN, a pilot that goes out repeatedly usually indicates a thermopile that is no longer generating sufficient millivolt output to hold the electronic gas valve open. Test the thermopile output with a millivoltmeter before condemning the gas control valve.
