Bradford White 243-54252-00 Control Box

The Bradford White 243-54252-00 Control Box and Wiring Assembly is listed in Bradford White’s parts book as the Control Panel Assembly, 5,000 RPM Ignition (item 4). It is the complete control panel for the Commander Series UCG commercial gas atmospheric vent water heaters. Parts list 238-54253-00 applies it to the UCG80H125, UCG80H199, UCG80H270, UCG100H199 and UCG100H270 models in the N and X gas versions.

Check the input rating on the nameplate. The 399 kBTUH UCG models use a different 3,000 RPM ignition control panel, so this 5,000 RPM assembly applies only to the 80H and 100H models rated 125, 199 and 270 kBTUH. The assembly shown is a light gray metal panel carrying a Resideo SOLA hydronic control with POWER, FLAME, ALARM and RESET indicators, a factory wiring harness with color-coded leads and plug-in connectors, and a ground lead. That control sequences ignition and supervises the flame, and its indicators are the first place to look when a heater locks out.

The same parts book itemizes the control panel components separately: the SOLA control module, the SOLA control display and display mount, the 120V to 24V transformer, sensor harnesses, the spark cable and the ground wire. Bradford White notes that ordering a complete assembly can lengthen delivery, so if only one component has failed, diagnose it first and order just that piece; if the panel is damaged by moisture, a lightning surge or a wiring fire, the full assembly is the faster, cleaner repair.

Key Benefits

• Complete Panel Replacement: The control, harnesses and mounting panel arrive as one assembly, so you are not chasing individual connectors and leads.
• Matched to 5,000 RPM Ignition Models: Specified for the UCG80H and UCG100H heaters in the 125, 199 and 270 kBTUH ratings.
• SOLA Control With Status Indicators: The POWER, FLAME, ALARM and RESET indicators speed up troubleshooting and lockout resets in the field.
• Genuine OEM Assembly: A Bradford White factory part for the Commander Series UCG platform, built to the original wiring layout.

Common Questions

• Which models does it fit? The Commander Series UCG80H125, UCG80H199, UCG80H270, UCG100H199 and UCG100H270 gas models, per parts list 238-54253-00. Verify the model and serial number on the rating plate.
• Will it fit the 399 kBTUH models? No. Those models use a 3,000 RPM ignition control panel, not this 5,000 RPM ignition assembly.
• Can I replace just one component? Yes. The parts book lists the SOLA control module, transformer, display and harnesses individually, so replace only the failed component when that is all the diagnosis calls for.
