Then, check if the on-off switch is lighted. Ensure that the operating temperature control is set higher than the current water heater temperature. Inspect the flame safeguard control for a bad ground or control, replacing it if needed. Verify that the combustion air blower fan connection terminals on the flame control are closed. Check for 24V at field access terminal C2, as a remote interlock may be open. Also, the fan VFD may be defective, verify proper voltage.

Inspect the flame safeguard control for a bad ground or control, and replace if necessary. Examine the hot surface igniter for its amp draw during heat-up, replacing it if amps exceed 3.1A, and check for overheating due to damaged refractory. Verify the air-proving switch isn't bouncing; adjust or replace it if needed. Ensure proper inlet static and dynamic gas pressure. Inadequate flame signal may result from improper combustion, so adjust to proper CO2 levels at low fire. Check for a proper ground from the flame control to the burner housing. Lastly, check all safety limits for a fault co...
