Bradford White Water Heater EF60T125E3N2

Service Procedure V — Blower Testing & Replacement

Warning: 120-volt potential exposure; use caution making voltage checks.

Confirm the blower energizes when the thermostat calls for heat

Check for 120VAC across the terminal-block black and white wires

Check for 120VAC at the ignition module/control board and blower wiring

Repair or replace the harness or blower as indicated

Does the blower energize but seem weak?

Check amp draw on the black blower-motor lead (should read 0.6–3.0 amps)

Confirm the blower wheel is secure on the motor shaft

Service Procedure II — Combustion System Testing

Observe burner operation through the sight glass

Verify minimum gas supply piping size

Confirm static inlet gas pressure is stable between 7 and 14 in. W.C.

Adjust or replace an inadequately sized regulator if pressure is unstable

For models with Hot Surface Ignition

Confirm the inlet gas pressure does not drop more than 2 in. W.C. during ignition

Check that the igniter glows through the sight glass during warm-up

Check for 120VAC at the ignition-module igniter terminals

Service Procedure VIII — Flame Sensor Testing & Replacement

Be cautious of 120-volt potential exposure and hot flame sensor

Check for a minimum of 1 microamp during the 1.5-second flame-proving period

Is the flame-sensing circuit okay?

Check for expected 24VAC at ignition module/control board flame-establishing terminals

Call technical support if 24VAC is absent

With sensor disconnected, check for continuity to ground

Service Procedure I — Thermostat Circuit Testing

Unplug electrical power to the water heater

Check continuity of the wire harness to the sensor

Is the resistance close to 0 ohms?

Replace the harness if resistance exceeds 0.5 ohms or wires show damage

Check sensor resistance against the temperature/resistance table

Restore power and run the heater through a heating cycle

Service Procedure XIII — Vent Safety Switch Testing and Replacement

120-volt potential exposure; use caution making voltage checks.

Confirm the exhaust collector compartment is not overheating (350°F) before resetting the switch; call technical support if there is evidence of overheating.

Locate the harness connection and check continuity through the grey lead wires of the heater-side harness; call technical support if there is none.

If continuity is present, depress the reset button on the high-limit switch and check for continuity across it, replacing the vent safety switch if there is none.

Reset the heater and observe a heating cycle to confirm the switch does not reopen before 350°F is reached; replace the switch if it opens prematurely, and do not operate the heater if temperature exceeds 350°F without contacting technical support.
