The model identifies a 50-gallon (50) natural gas (N) atmospheric water heater with Bradford White’s FVIR Defender Safety System (F). Parts that most often need replacement include the pilot assembly and thermocouple, the gas valve, the MI5036FBN anode rod, and the dip tube.

MI5036FBN Water Heater Build Details
This MI5036FBN uses a gas burner, so there is no electric MI5036FBN heating element, and the MI5036FBN thermostat is part of the gas control valve rather than a separate component. Its parts list shows two pilot designs across production: a pilot with a thermocouple and spark igniter, and a pilot with a thermopile. The two are not interchangeable, so match the pilot on your heater to the diagram before ordering. The FVIR system includes a flame arrestor and a thermal switch; the list for this model shows a resettable thermal switch. The MI5036FBN manual and MI5036FBN diagram cover lighting, venting, and component positions. For MI5036FBN repair steps, visit the water heater troubleshooting page.
Most Replaced Parts on the MI5036FBN
Pilot Assembly, Thermocouple, and Thermopile
A pilot that lights but goes out when you release the button points to the flame sensing part of the pilot: the thermocouple on one design or the thermopile on the other. Test it before suspecting the gas valve. If the pilot will not spark, check the igniter switch and lead. Order the pilot assembly that matches your build.
Gas Valve, Thermal Switch, and FVIR Shutdowns
If the burner shuts down and will not relight, check the flame arrestor and air intake for lint or dust first, then test the thermal switch. Replace the gas valve only when the pilot sensor and thermal switch test good and the valve still will not hold or regulate.
Anode Rod and Tank Protection
The anode rod corrodes so the tank does not. Inspect it every two to five years, sooner with hard or softened water, and replace it when the core wire shows. A sulfur smell from hot water often means the rod is reacting with the supply. Order a matching anode rod.
Dip Tube and Fast Hot Water Runout
A cracked MI5036FBN dip tube lets cold inlet water mix at the top of the 50-gallon tank, so hot water runs out quickly or turns lukewarm. Plastic flakes in faucet aerators confirm it. Replacement tubes are under hose, tube, and fitting parts.

MI5036FBN Water Heater FAQ
Why won’t the pilot on my MI5036FBN stay lit?
The thermocouple or thermopile on the pilot is the usual cause. Test it first. If it is good, check the pilot orifice for debris and the arrestor for lint before suspecting the gas valve.
Which pilot assembly fits my water heater?
This model has used both a thermocouple pilot and a thermopile pilot. Compare the pilot on your heater with the diagram and order the matching design.
Does this water heater have a heating element or separate thermostat?
No. It is a gas model, so the burner heats the water and the thermostat is built into the gas control valve.
Why does my hot water run out so fast?
A broken dip tube, sediment buildup, or a worn burner can cut capacity. Check for plastic pieces in faucet aerators, which point to the dip tube.
