Bradford White 243-46614-02 Control Box

The Bradford White 243-46614-02 Control Box Assembly (Single Sensor) is the factory control box for the single-sensor D-Series commercial gas water heaters that Bradford White builds with an automatic flue damper and electronic ignition. In Bradford White's own Commercial Gas Replacement Parts List 238-47821-00, it is the control box on the D75T125, D75T160, D100L199, D100L250, D100L270 and D100L300 models, including the suffix variants shown in that book. On the D100L models the book limits this box to heaters with serial numbers prior to GB13067706; heaters built on or after that serial use the dual-sensor 243-46560-03 control box instead.

The control box is the enclosure that carries the heater's electronics and wiring. For these single-sensor models the parts book lists the Integrated Control Board (Single Sensor) 233-47260-00, the Resideo temperature control display 233-46557-00, the 110V transformer 415-44072-01, the power on/off switch 239-49391-00, the control box cover assembly 243-46615-01, the control box cover 239-46509-00 and the control box panel 239-46508-00. The wiring around it includes the damper wiring harness 239-46527-01 or 239-46527-03, the gas valve control wiring harness 239-46529-01 or 239-46529-02, and the display, transformer and power cord harnesses 239-46944-00, 239-46617-00, 239-46531-00, 239-46530-00 and 239-46533-00. Those items are listed separately in the parts book, so check what is already on your heater before you order.

The dash number identifies the revision and the model and serial range it was built for. Siblings in the same family include 243-46614-01 (the D38T155 models) and 243-46614-03 (the D100S199 and D100S250 models, serials before HA14465923), while the dual-sensor boxes are 243-46560-01, 243-46560-02, 243-46560-03 and 243-46560-05. A single-sensor box pairs with the 233-47260-00 board and the 239-46527 damper harness; a dual-sensor box pairs with the 233-46616-00 board and the 239-46526 harness, so the two are not interchangeable. A control box is normally replaced for water damage and corrosion, burned or melted wiring, a cracked housing, or intermittent power and display faults traced back to the enclosure wiring. Before condemning it, confirm the 120V supply, the transformer output and every harness connection. Shut off gas and electrical power, photograph the connectors before you disconnect anything, and verify the flue damper operates through a full cycle after the work.

Key Benefits

• Factory Bradford White Part: The OEM 243-46614-02 control box, not a universal enclosure.
• Parts-Book Fit: Listed in Bradford White's 238-47821-00 book for the D75T125, D75T160 and D100L models.
• Single-Sensor Match: Pairs with the 233-47260-00 integrated board and 239-46527 damper harness used on these heaters.
• Documented Companion Parts: The transformer, display, switch, cover and harness numbers are all identified, so one service call covers the whole box.

Common Questions

• Which water heaters use the 243-46614-02? The D75T125, D75T160, D100L199, D100L250, D100L270 and D100L300 commercial gas models. On the D100L models it applies to serial numbers prior to GB13067706.
• What if my D100L was built after serial GB13067706? Those heaters use the dual-sensor 243-46560-03 control box. Read the model and serial number on the rating plate before ordering.
• How do I tell the single-sensor 243-46614 boxes from the dual-sensor 243-46560 boxes? The 243-46614 series is single-sensor and the 243-46560 series is dual-sensor. They use different control boards (233-47260-00 versus 233-46616-00) and different damper harnesses, and the -01, -02 and -03 dash numbers are tied to the model and serial ranges listed above.
