What Solid ON (red) means on a Bradford White water heater
On Bradford White water heaters equipped with the Gas Control V2 unit, a solid red LED indicator does not represent a fault condition or system malfunction. Instead, this steady red light is a deliberate status signal confirming that the gas control valve has been placed in the OFF position. The control module uses this illumination pattern to distinguish between an active shutdown state and other operational or error states that use different LED behaviors such as blinking patterns.
The Gas Control V2 is the electronic brain of the water heater, managing gas flow, ignition sequencing, temperature regulation, and status reporting through the LED indicator. When a user or technician rotates the gas control knob to the OFF position, the control immediately registers this input and holds the red LED in a continuous solid-on state. This is by design, giving a clear visual confirmation that gas flow has been intentionally interrupted and the unit is not attempting to fire.
Because this is a normal operational state rather than an error, no troubleshooting of components is required. The appropriate response is to simply wait until the LED extinguishes, which signals the control has fully transitioned out of the OFF state, before attempting to restart the unit. Restarting before the LED clears can result in improper ignition sequencing. Once the LED is off, the knob can be rotated through the pilot lighting sequence to resume normal operation.

Common causes of Solid ON (red)
- 01
Gas control knob turned to OFF
Wiring / connectionThe most direct cause of this indicator is the control knob being manually rotated to the OFF position, either by a user, technician, or during a previous service visit. Check the position of the knob on the gas control valve.
- 02
Intentional shutdown before service or vacation
Wiring / connectionHomeowners or technicians often turn the unit off before performing maintenance, leaving for an extended period, or shutting off the gas supply. The solid red LED will remain on until the control fully powers down.
- 03
Control knob bumped or moved accidentally
Wiring / connectionIn utility rooms or tight spaces, the gas control knob can be inadvertently rotated to OFF if something comes into contact with it. Inspect the knob position and surrounding area for anything that may have shifted it.
- 04
Post-shutdown state after a prior fault clearance
Wiring / connectionA technician may have rotated the knob to OFF as part of a reset procedure following a previous fault condition. The unit remains in OFF state until manually restarted through the pilot lighting sequence.
